Circumventing the Glass barrier for Solar

We know solar panels as big flat frames with glass in front and an aluminium rim, plastic at the back. They are quite heavy, for instance the 320 Wp LG Neon Black panel we recently used in a 10 panel installation weighs 18 Kilogram.

Strangely there is no real need for both the aluminium and the glass in these panels, but they have been required by law for panels imported in the EU. Solar panels have been put under severe scrutiny from the beginning (apart from Shell basically killing the industry for 20 years) simply because they compete with the then very rich and ruling energy cartels. You can find many examples of how the fossil energy interests have stifled development or market entry of renewable energy sources, this is just another one of them.

Saint Gobain has a lot of Building Integrated PV experience

For ‘bespoke’ panels or ones made in Europe rules must be different. 10 years ago already we say simply laminated plastic panels measuring 3 by 4 meters about, at the Saint Gobain factory when we visited to test some glass laminated panels. Once you have a big machine that can melt the EVA you can make panels using UV resistant plastic that last a long time. Those panels with big cells (20 cm x 20 cm) where not for sale as far as we know.

Tesla Solar Roof tiles are made of laminated hardened glass and meant for a more esthetic roof

Now there are new types of glass. Thin films of glass can be laminated together to build bridges and car roofs (like in the Tesla Model 3, X and S). Glass when thin is more elastic and the lamination distributes forces to make it even more resilient to cracks and impact. This seems to create a loophole in the “a solar panel needs a glass front” rule.

Solarion glass foil panels

The above panels look like the 12 volt laminated ones for caravans and boats, but apparently they are 210 Wp roof PV panels. Frameless yet with glass fronts. We think this is an important product to come on the market, because it is greener to produce, it is as effective but less of a hassle to install.

“The Solarion M210 glass-foil modules are encapsulated framelessly between a glass panel and a plastic roofing membrane”

There’s a trade off between solar panel angle and the yield per rooftop m2. Say you have 17 meters by 4 meters, you can fit 40 320 Wp solar panels on that space and produce 12800 Wp with less yield because they lie flat or you can make two rows of 10 panels each at a 30 degree angle (in Holland) and produce 6400Wp with maximum yield. For some the total output of the roof is the most important thing. Compare

Stuff needed for normal solar installation :

  1. Panels
  2. Supports (22 x 25,-)
  3. Balast (about 900 Kg)
  4. Lots of manpower and time

vs. the flat roof installation:

  1. Panels
  2. Glue?
  3. Less manpower and time

The cost advantage is not only in less stuff but also in the panel itself and in the hassle of its logistics. The glass/aluminium framed panels are heavy and fragile, they are 4 cm high typically so you need space and power to move them. They require a serious logistics chain to produce, from bauxite mines to desert glass melting plants (in Mauritania for instance).

Flush (traditional) panels in Australia

All in all we think this type of panel, along with the Tesla Solar Tiles will quickly start to dominate the market. We are at least happy a product like this is available to speed up introduction of solar to its maximim, because that is what is needed. They are not for “Low load bearing roofs” but for breaking through the idiocy of heavy glass/aluminum panels!

Climate Anger or the coming “Climate denial shit no longer flies” moment..

The world is slowely discovering it is screwed, at least the world that’s not to preoccupied with competing for their part of the fossil driven world economy (or too desperate because they’ve been excluded from it wholesale).

Africans should be angry, because the western countries and their fossil credit banks are still eyeing and working to get a hold of their minerals and ores, forrests and whatever else isn’t welded or bolted to the ground. In Asia people are suffocating because of either palm oil fires, coal power plants or drought induced wildfires.

Indeed the above tweet says it all. Neoliberalism and related pro fossil credit political philosophies have (for indivdual commerical reasons) all sold out to perform a dance to entrance the public, ravel it in fake conflicts and antagonisms, just like the main stream media have been doing. Whoever consumes media is at risk of drowning in an upsetting storm of irrelevant memes and tropes, all to paralyze us and disable us from exiting the current economic model.

Regional government states that even existing plans will have to be altered to conform to zero-emission housing targets.

To escape any situation anger is called for. What does anger do? It fixes our minds on something that’s either out of our comfort zone or moving out of our reach because of external pressures. An angry mind persists hoding on to an idea, whether this is a territory or a self image or the relationship with someone else. Anger means we can drop everything in order to protect whatever idea we are angry about. To say “To hell with the world, but the world is not going to hell!” sounds contradictory but it isn’t.

We will hopefully see more “must change” or “Will be altered” “Scrapped” “Revised” and other expressions of hard line climate action even against strong lobbies (like coal). This is anger at work : What we where hoping to do is wrong and bad for our future, we will discard those plans and make new ones that take into account the need for people to survive, not that of the banks and fossil energy cartels.

We’re heading to a “climate denial shit no longer flies” moment. Lies kill people.

On a more human level this will mean we will see more doing in spite of objections and warnings, but this time not building a gas pipeline in spite of resistance, but shutting down pollution plants in spite of it’s resistance, or maybe even scrapping gas pipes in spite of whoever is backing it. The anger is there and it is building because one can take only so much fake incompetence and lying.

The Economics of a Useless Narrative, or why Kate Raworth gets attention.

Kate Raworth is all the rage these days. She presents a donut shaped representation of the nine planetary boundaries and asks economists to think about it when they use their simple model of producers and consumers. It sounds great. We need to take care of poor people, our planets resources etc. You’d think we’d be happy, but we’re not. The reason is that she fails to do two very important things :

1. Do more than state the problem

Our world economy is defended by econonomists, not designed by it. It’s already running, money flows, resources get scavanged and mined, oil (very imporant) drives trucks, cranes and the banks try to optimize their profits and the amount of money flowing. Economists have one option : To work in service of that system. The other option is to not work or choose another profession. Why? Because they are the key salespeople of the economic system, the ones that will always sell it more no matter what you say. So does Kate. This is the second failure:

2. She fails to name the key driver behind all the destruction : Fossil energy

Granted, she does mention that the flow of energy is very important, but then she talks about the sun, food production. She never mentions oil, gas, coal. This is insane. Our economic system would instantly collapse if we could not buy oil, gas or coal with our money. Every transaction we make still largely depends on some fossil fuel being available somewhere to burn, whether in the factory, the power plant, the truck, the home of the worker.

What kate does is exactly what banks (World bank etc.) have been doing for decades, which is to focus on fighting poverty. What does that mean? Expansion of fossil fuel use (if you don’t put the focus on that). How do we know Kate is old school? Because the use of solar, wind, renewables totally upends the economic system, and totally breaks the domination of that production/consumption cycle.

Fossil energy drives pollution also because it allows competition where there would not be the resources for it otherwise. The most stark example of this is wars. Fossil fuels allows for the production of weapons for both sides, endless amounts. Only when people fight over fossil fuels is there any reason for banks, oil companies, industry to stop the fighting.

Kate simply restates the problem and then distracts us from the real challenge, which is how to have an economy based on replenishing resources like sun and wind. We have written about the Roboeconomy before, which is an economy where robots do most of the work, including restauration of our ecosystems, all running on renewables.

The roboeconomy will come about as extraeconomic nuclei grow and connect into networks of waste free, energy self sufficient wealth creation systems.

A key aspect of the roboeconomy is the growth of ‘extraeconomic’ nuclei of activity. These are regions where interaction with the wider economy is not allowed or not necessary. Imagine a water botteling plant, that runs on solar, that has solar trucks, that recycles bottles it brings back from the supermarket itself, and that also recycles bottles using solar. All this fully automatic. What will the cost of water be? Of course there is an initial investment, but what if the plant was set up using cash, no loans. Then it could run with minimal maintenance (of course there will be maintenance robots). It will outcompete all other water brands.

A simpler example is a zero-meter house, one that doesn’t need any fossil or electricity energy input. Such a house doesn’t have gas, electricity connections, it doesn’t make money flow but it keeps it’s owners warm and comfortable. It has become an extraeconomical island because if it is fully owned, payed off, then the owner barely needs to go out into the world to work. Only for some food. But if it has a basement with hydrophonic vegetable robots that run on solar from the roof, even that is no necessary. Think zero-meter greenhouses. Of course right now hydrophonics is used to sell as much plastic oil and other crap, because it exist in an economy that has a core function : To maximize the utilization of fossil fuels.

The key strategy of the fossil fuel/banking or what we call the carboncredit system is to distract us by making us look for solutions 1. Where there are none 2. That involve using the fossil credit economy.

So we are not impressed with Kate, she is a distraction and she doesn’t point out the real challenge to economics, which is that it will have to deal with the disappearance of banks, of big financial institutitons, and needs to prepare to become expert in the managing of local autonomous independent ecosystems, EVEN independent of bank loans. Surprisingly enough economics is already pretty good in these things, because most companies function as autonomous independent systems, with one difference, they’re always deep in debt and working hard to pay it off (or just pay the interest) by seeking profit and being agressive in the market. This is where the biggest change will come : Less competition.

Just think of the bakers in the world. Most of them don’t compete, they fullfill a function locally, they are spread out over the urban areas quite evenly. They don’t have to go into deep debt to dominate the bread baking world, at least not if there isn’t some crazy financial tirant in charge. Of course we do have global bread, bagel, donut, hamburger franchises, which compete unfairly (judging by the tax incentives). But we don’t need to, and we won’t have them if bakers and farmers cooperate to grow, harvest and bake in a closed cycle extraeconomic system. Then bread will be very cheap or even free.

Kate puts poverty first, then living within our ecological means. If we don’t do the second thing first, we will never be able to do the first in any lasting or meaningfull way, in fact, we’re likely to do the first by doing the last.

The above will happen with many products we use, they will become debt free autonomous production systems. The largest portion of the money, which now goes from consumers to the fossil energy companies through the banks, will evaporate. Money will mainly be used to divide tasks because 1. energy will never be payed for and 2. resources will always be recycled. 3. labour will be avoided when it isn’t spiritually enriching. Kate’s trick is to mention all the aspects that we need to consider and strive for but not the key change which is the dissapearance of fossil fuel cashflow and credit dependence. Yes of course we should consider our well being, of course we should work within the limits. The real challenge for economists is to understand the robo- and extra- economy, but that’s really not what their future employers (banks, financial institutions, insurance companies etc.) want. Nor Kate.

Johan Rockstrom (Mentioned by Kate) Adapt, resilience  Johan Rockström massive challenge feeding 9 billion people. “We can not expand , we have to use current land” “Carbontaxes it won’t work” “We can feed the poor” “What are the planetary boundairies”. Rockstrom is also a pro fossil typical ‘adapt, move with the punches’ non contributor.

Will Steffen (also mentioned by Kate) How do we fit in with the cycles of the planet. Reduce pressure of agriculture. Carbon neutral aviation fuels. That sounds much better, short term solutions.

The Impossible Responsibilities of a Consumer

We follow the news, we learn what is going on in the world, and it’s not pretty. What we see is that there’s powerfull technolgies, dangerous industrial processes, bands of agressive profit seekers that are not controlled. Talking about the ‘economy’ is just a weak attempt to feign structure and coherence, in fact, the Ubers and fracking companies and other ‘disruptors’ show us there’s only as much prosecution of crime as there is profit in prosecuting.

Here’s the thing : We’re born human. We have a limited capacity to grasp our surroundings, we try to find food, shelter, company. Of course we are raised in a culture where those things are readily available and there’s lives that can be lived with lots of quality and happiness, and then there’s ones that suck, that in some cases matches our talent, in others are the result of oppresion and abuse.

But no human sits in his room and thinks “Lets build a nafta cracker” or “Lets roll out a mobile phone network”. These things have come about because of organizations larger than man. They are industrial products, created by many small steps. Motivated by ‘profit’, which is what you need to be able to take more small steps towards more profit. In the process the people in those industries had better lives for sure, but they never stopped eating, drinking, sleeping etc.

This is all fantastic, and we should thank those that discovered penicillin, then found a way to grow it in eggs, then found a way to industrialize that growth process and make the cure to many infections available across the world. Of course you could thank  banks who invested and supplied the infrastructure to trade and manufacture and get things done, even if their main goal was to 1. own everything and 2. sell fossil fuel credit.

The problem is that a new born child will never grasp all of what’s going into enabling its modern life. Many people living today never really tried to understand how a phone works or a television or the internet. They are what we call consumers. They work at a job that has modest economic value, and they live lives as if they where hamsters in a cage really. If they get sick they don’t know how to cure themselves, if the car breaks down they don’t know how to fix it, if they TV or internet stops working they have no clue… And if a nuclear powerplant or refinery nearby explodes what can we expect of them?

You could answer : There there are fire fighters and experts who fix things. You’d think that. But of course the consumers we described above never made sure that was the case. So maybe there isn’t a fire department, or a well trained body of experts to deal with a nuclear calamity. You’d think industries all have thier safety institutions, but they might not, they might not be up to date, they might have become underfunded because politicians not doing their job.

A consumer can’t tell if a politician that tells them taxes go down and immigrants will be send home also takes care of the risks of industry. We may pretend citizens all have this responsibility when they vote politicians into office, but how can a consumer know who is primarily preoccupied with his/her own life know? How can a voter know what the consequences are of voting for Trump or for Clinton? Now that it is Trump how can a voter be held responsible for what EPA chief Scott Pruitt decides to do? How can we pretend a voter is responsible for policy if the corruption is so blatant (like a member of parliament claiming it’s commonplace to be payed by the industries one makes decisions on, or Trump supporting Puerto Rico recovery by handing $300 mln to a company of one of his campaign donors).

The basic consumer in our economy now is expected to keep a machinery going, keeping it safe and well monitored (which when it harms profits of industry is under threat). How can a consumer be expected to ensure medical services remain of the highest standard. How does he/she know we are executing the best policies to ensure health and future of all, meanwhile maximizing the wealth that people create in their jobs? It is insane to expect that!

A big reason why we should NOT expect a consumer to be able to bear this responsibility is because our economy has incentive loops, local reinforcing effects that instead intice people to be irresponsible, especially when they are in a job that gives them control, a job that is entrusted to them because people believed they could handle the responsibilities.

For example, a medical doctor gets invited to a course by a pharmaceutical company. They produce pills that are twice as expensive and a bit more or as effective as the alternative. They come with a training course held in Aspen, Colorado, in the winter. Of course this doctor will go on this trip, take his wife and children. Then he will prescribe the pills, and more money will flow around the system. He doesn’t know more about the pills than the pharmaceutical company tells him, so if 20 years later the pills prove to have been worthless or toxic who can we blame. No consumer patient of this doctor will ever get to decide or know (in most cases).

The incentive loops and shortcuts seem now to have spawned completely fallacious politicians. Trump, May, those involved in Brexit, they lie and lie and lie, but they make the rules the consumers must live by. The incentive shortcut is so obvious in the US, where campaigns are expensive multi hundred million dollar things. The media breath in that money every four years (unless there is an assasination), and will let opponents compete for add space. This is why channels like Fox and CNN are increasingly partisan, it is simply cheaper to buy a channel than to pay to get on one. But how is the voter to be considered responsible for this?

People are dying of hunger and thirst in Puerto Rico, and Trump plays with their dependency (not even aware PR is part of the US) of course other pars of the US are a mess because climate change was not addressed in time, because of the same incentive shortcuts that have nothing to do with the voter. Members of congress are immune from prosecution for insider trading, so if you want to bribe one, just tell him a stock ticker name so he/she invests. Then you buy a lot of those stocks, raising the price, then the congressman/women cashes in, and you get your text in the bill. Of course no lawmaker will think of a law by themselves anymore, they come al ready to copy paste!

The consumer is left with the choice to either be somewhat informed, angry and unhappy or be ignorant and happy. Of course the latter means the world goes to shit, becuase the incentive loops creep into every safety measure that reduces profits for the companies and industries they work for. Consumers want to work, earn money, enjoy their lives that fullfill their dreams, and thus will not care if clother mean slavery, meat means torture, clean air and water become a thing of the past and the Earth swings into climate chaos..

Even though some consumers feel and act responsibly, they do not know a tiny % of what still goes terribly wrong, and in some cases (like in the US right now) they can’t even fathom all they ways their lives are increasingly contained in an industrially designed straight jacket, while the resources they imagine to exist (because nature movies) are being used up, not replaced. They don’t even know if the life they live is the best possible because control and ownership over the local surroundings is minimized and channeld to stuff that makes them good consumers.

The author of this is old school, empirically minded and raised frugally. Now poverty will depress you and make you more realistic (because depression -is- being aware of the bare reality of your life), and thus less of a good consumer. The consumer ‘trusts’ things go right in parts of the economy they don’t understand. A realistic person just feels anxiety about what can go wrong and affect his/her life that is out of his/her control. A war in the middle east or a nuke fired from North Korea to mainland US, a crash of the financial system, a hacking of a nuclear plant or the grid, release of bubonic plague, hospitals without staff, gas stations without gasoline, bakers without bread, no water etc. etc. It all has to go right and the system that should make that happen is out of your control..

Trump not keeping his promises means that your vote for him (if you voted) gave you no control whatsoever. Your vote for Clinton didn’t either, so that once in 4 year event was a useless exercise. You can’t be held responsible, you did not get the responsibility, you are not responsible. Even Trump is not. Nobody is it seems, there are just (financial.status,sexual) incentive loops, and it takes genuine experience and insight to know which of those we should protect and which we should break, if we are even able to do. But the consumer is not able in most cases.


It should be the job of every citizen/consumer to constantly reduce the power of the most powerfull over them. If power can not be trusted to consider their interest, it should not exist. To vote for congress where every representative is backed by millions makes no sense. The average voter is not going to get served. What the politician will do is to make the voter worry about super irrelevant issues like abortion or immigrants, where changes are not going to change the lives, while tax incentives for campaign sponsors are silently implemented. The voter/consumer/citizen should not believe the hype.

It sounds backwards but today nobody needs to decide to build a nuclear reactor anymore. They are obsolete. We have solar/wind/geothermal and wave energy sources which can be easily understood, controlled and managed. Doing this as local as possible makes a lot of sense, and takes power away from unkown, untrusted entities.

Banking need not be global of super long range in most cases. The essential trade is between farmers and non farmers, because one creates the food the other group needs. All other trade is luxury, when there is no trade necessary in water or energy.  So the logical thing is to more clearly connect the farmers and the consumers, so that both know where the other is. Of course the US shielded itself from famines by using printed dollars to buy food of the world market, leading to hunger in the supplying country in some cases!

Once the focus is more on local autonomy, the incentives to lobby and influence a central government weaken, and lawmaking can once again be driven by widely shared concerns, ones people are willing to sacrifice and change their behaviour for.

A simple example is that in the formation of the new dutch government, a law change was added that didn’t come from any of the cooperating political parties, none had suggested to abandon divident tax, which taxes income from holding stocks and bonds. Who did? The VNO-NCW, a right wing (but pretend neutral) advisory board to the government. Why? To lure in Brexit banks and companies (who think about leaving London). The cost of this measure was calculated to be 1,4 Billion Euro. This was expected to be available for education healthcare what have you, but apparently -no- politician decided to give it away.

A normal consumer tied up in his/her lives never thought about the tax break above, never cared where London banks run their business. But in the banking world, real estate world, expat rental world, a financial incentive emerged to tweak the laws so banks and other companies where more inclined to come to Holland. Politics out of control!

The incredible responsibilities we all have to keep our lives safe from calamities with industrial installations or unintended consequences of laws created for profit seems to dictate that we all make an effort to reduce the existing powers to a size we can understand, and that we limit our consumption to where we can see the origin of what we consume. How else can we pretend to be responsible, and if we don’t want to be responsible, how can we feel safe?

Moondust Concept

Earth must cool down. The climate is heating up, and positive feedback loops are kicking in. The habit of geoengineering with fossil fuels is not working for us, we need to geoengineer in the other direction.

To cool the Earth different approaches have been proposed. We could cool it by pumping up deep ocean water, which would also increase O2 generation at the surface. The usual reference is to sulfur powder release in the upper atmosphere, which would reflect sunlight. It would also be quite polluting and rain down on Earth like acid rain.

Maybe there is a less chemically or practically challenging way to reduce the amount of sunlight that reaches the Earth, and that is to rain moondust on it. We didn’t calculate but the idea of a giant dust blower on the moon appeals to us.. It would send dust in the general direction of Earth, then the dust would fall through the atmosphere and reflect sunlight. Once the cooling has allowed life to reabsorb enough CO2 the amount of dust can be reduced..

DigID als Melkkoe

Sinds een jaar of 12 is er DigID, een manier om digitaal in te loggen om zo informatie uit te wisselen met onze overheid. Het heeft gemeenten in de loop der jaren geld gekost, maar ook geld bespaard, en zelfs de service verbeterd. Nu kun je zo van je laptop, tablet of smartphone belangrijke documenten aanvragen, invullen waar je hebt gesolliciteerd of je BTW aangifte doen.

Technisch gesproken is DigID niet zo bijzonder Het is een user/password login, soms met SMS bevestiging. Dat is vrij normaal en zeker niet duur om te laten werken. Je moet het een keer bouwen, maar je kunt de onderdelen letterlijk van het internet plukken. De SMS kost een paar cent per keer. DigID is net zo veilig als de PC of smartphone van de gebruiker. Als die een verkeerde site bezoekt die een keylogger installeert (een onmerkbaar programma dat elke toetsaanslag vastlegt en stiekum naar criminelen stuurt), dan ben je de volgende keer dat je inlogt het haasje. Dat kan beter. De Rabobank heeft een systeem dat werkt met een rekenmachientje dat elke keer op basis van een QR code een nieuw wachtwoord (een getal) verzint.

Enfin. DigID heeft natuurlijk wel een ambtelijk molen om zich heen voor het versturen van brieven enz, en er moet goed opgelet worden of niemand de database hackt of zonder keylogger in gegevens van mensen inbreekt. Maar die kosten vallen in het niet bij de besparingen, en kunnen gespreid worden over ~2200 gemeenten. Het lijkt ons dus niet nodig om iemand te laten betalen voor het gebruik van DigId.

Natuurlijk kan het zijn dat een commerciele partij, bv een energie bedrijf, ook achter het DigId wachtwoord wil, bv. omdat mensen dat makkelijker vinden dan een los wachtwoord onthouden, of omdat dit goedkoper is (en dat is het ook). Die bedrijven mogen betalen omdat ze kosten sparen en omdat ze geen publieke dienst leveren maar een product op de markt aanbieden. Als de concurrentie geen gebruik van gratis DigId maakt zou er prake zijn van oneerlijke concurrentie.

Voor de burger moet DigId echter gratis blijven, of het schiet zijn doel volledig voorbij. De burger zou geld toe moeten ontvangen nu er minder mensen in het gemeentehuis hoeven te werken. Als dat niet zo is dan nog was het niet de burger die hiervoor moet opdraaien, niet bewust althans.

   To our Podcasts en Irrelevante Onzin

Niet elke site over duurzaamheid is ook bedoelt om duurzaamheid te bevorderen, de lobby voor fossiel en voor centrale energie distributie (grid) vind plaats op veel niveaus. Het is daarom slim om af en toe een site te checken die lijkt een duurzame uitstraling the hebben.

De site “Low Tech Magazine” trok onze aandacht omdat er een post op kwam te staan die wat opzet en inhoud niet van deze tijd is, maar echter zeer herkenbaar, hieronder de url

Hoe duurzaam is een duurzaam elektriciteitsnet?

Laten we dit stuk eens bekijken, eerste alinea :

“Hoewel het potentieel van wind- en zonne-energie groter is dan de energievraag van industriële samenlevingen, zijn deze energiebronnen niet altijd beschikbaar. Om te verzekeren dat het aanbod altijd aan de vraag kan voldoen, heeft een elektriciteitsnet op basis van wind en zon heel veel extra infrastructuur nodig.”

De voorstanders van het smart grid redeneren dat de variabiliteit van hernieuwbare bronnen kunnen worden opgevangen door stroom van andere plaatsen aan te voeren. Daarvoor zou meer infrastructuur nodig zijn. De energie die van ver komt kan fossiel, getijden, golf of wind zijn. Infrastructuur is een zeer brede term, waar ook batterijen onder kunnen vallen, maar dat wordt hier niet bedoelt. Dat is zo al vreemd omdat batterijen natuurlijk het antwoord zijn op genoemde variabiliteit.

Tweede alinea :

“Die infrastructuur maakt van hernieuwbare elektriciteitsproductie een complexe, trage, dure en onduurzame onderneming. Als we daarentegen de energievraag zouden aanpassen aan het wisselende aanbod, dan kan hernieuwbare elektriciteitsproductie wel heel voordelig zijn. Deze strategie was heel gewoon in vroegere tijden, en moderne technologie maakt ze nog interessanter.”

He? wat? Ok, dus het grid (waar wij doorgaans niks van merken) uitbreiden zoals hierboven noodzakelijk geacht, kan opeens niet. Dat is ook weer een beetje kort door de bocht. Er wordt geopperd de energie vraag aan te passen aan het aanbod, dus geen infra, geen batterijen, maar meeleven met zon, wind enz.. Dat lijkt ons mogelijk (bv. vrieshuizen van veilingen kunnen koude bufferen als er aanbod is van zonne electriciteit, en zo ‘s nachts geen stroom nodig hebben)..

Derde alinea :

“Het idee leeft dat hernieuwbare energiebronnen ons in de toekomst onafhankelijk zullen maken van fossiele brandstoffen. Windenergie en zonne-energie hebben met voorsprong het grootste potentieel. De hoeveelheid energie die Europa praktisch kan uit de wind kan halen, wordt geschat op 30.000 terawatt-uur (TWh) per jaar, of tien keer meer dan het jaarlijkse energieverbruik. [1] Het potentieel aan zonne-energie in de VS wordt geschat op 400.000 TWh, of 100 keer het jaarlijkse energieverbruik. [2]”

Ok, afgezien van de rare zinsbouw…

“In praktijk zijn dit soort uitspraken problematisch. Ze zijn gebaseerd op jaarlijkse gemiddelden, en houden totaal geen rekening met de variabiliteit van windenergie en zonne-energie. In een elektriciteitsnetwerk moeten vraag en aanbod altijd in evenwicht zijn. Dat is relatief makkelijk met fossiele brandstoffen, want die zijn op afroep beschikbaar. Maar de opbrengst van windturbines en zonnepanelen is totaal afhankelijk van de grillen van het weer. “

Daar zijn we weer, die variabiliteit. De eropvolgende alineas zeggen dit over wind en zonne energie, dat is ook bekend. Geen probleem als je de stroom ergens kwijt kan. En de gemiddelden vertellen je dan precies hoeveel stroom je zult kunnen opslaan, als je dat niet doet dan heb je natuurlijk een probleem, maar ook kolencentrales worden bij en afgeschakeld, en in het huidge net zitten al verschillende energie buffers.

“Ten eerste zouden we kunnen rekenen op een reservecapaciteit van klassieke elektriciteitscentrales die op fossiele brandstoffen draaien. Die centrales worden dan ingezet als er onvoldoende wind en zon is. Ten tweede kunnen we veel meer windturbines en zonnepanelen plaatsen, zodat er zelfs bij bewolkt weer en bij lage windsnelheden voldoende hernieuwbare energie is.”

Elk redelijk up to date persoon herkent meteen dat hierboven het probleem kunstmatig in stand wordt gehouden. Dit doe je door fossiele buffering voor te stellen of meer wind en zon zonder over opslag te praten. Dat gebeurt in de volgende alinea’s onder de titel “Strategie 1” en “Strategie 2”. Beide zijn natuurlijk slechte oplossingen, hoewel we grote voorstander zijn van hernieuwbare “overcapaciteit”.

“Strategie 3” is (verrassend) meer grid! Dus Europees Elektriciteitsnet, dat er al is overigens, maar dat uitbreiden :

“Voor een Europees elektriciteitsnet met een aandeel van 60-100% zon en wind moet de capaciteit van het hoogspanningsnetwerk zeven-twaalf keer groter worden.”

Dit zijn berekeningen in de trant van “Als we de boot willen leegscheppen met een theelepel zijn de drie jaar bezig.”. Je kunt zo al zien dat deze denkrichting tegelijk dom en kansloos is. Waarom deze zo uitgebreid aanhalen?

“Strategie 4”. Energie opslag, ok, nu komt het! Het is een goed idee maar er zijn problemen..

“Ten eerste: hoewel er geen nood is aan het bouwen en onderhouden van een reservecapaciteit van fossiele energiecentrales, wordt dit voordeel teniet gedaan door de bouw en het onderhoud van de energieopslag. Inderdaad, dit heet vooruitgang, veel minder complex, een batterij kan automatisch functioneren, een centrale niet!

Ten tweede hebben alle opslagtechnologieën laad- en ontlaadverliezen, en bijgevolg zijn er meer windturbines en zonnepanelen nodig om dit verlies te compenseren.” Het grid heeft ook verliezen, maar die zijn groter. Een van de 40 centrales in Nederland draait alleen om de grid verliezen op te vangen.

“Onderzoek heeft uitgewezen dat het efficiënter kan zijn om windenergie te vernietigen dan op te slaan: de energie die nodig is voor het bouwen en onderhouden van de energieopslag, is groter dan de energie die verloren gaat als de turbine wordt stilgelegd. ” dit is onzin, de Giga factory van Tesla gebruikt zonne energie voor batteij productie, maar in het algemeen is er geen verhouding tussen de energie voor het bouwen van opslag en de energie die een turbine levert.

Er wordt vervolgens uitgerekend dat er vele terrajoules opslag nodig zijn om de hernieuwbare energie te bufferen. Dit lijken ons grote getallen, zoals bv 1,5 maand productie equivalent. Waarom 1,5 maand energie opslaan, dat krijg je niet eens opgeladen! Wat wordt vergeten is dat de aanvoer en delving van fossiel miljarden kost, en ook energie vreet, want kolen zweven niet vanzelf naar de centrales, en gas en olie infrastructuur bouwen zichzelf niet. De energie nodig per vat olie is in de laatste decennia gestegen en kan makkelijk groter dan 1 zijn, dwz voor 1 vat olie op de markt worden 40 vaten olie verbrand. De laatste zin over opslag maakt de tendentieuze aard van de ‘analyse’ duidelijk:

“Er zijn veel andere technologieën voor het opslaan van energie, maar die hebben allemaal unieke nadelen die ze onaantrekkelijk maken bij gebruik op grote schaal.”


“De nood om het hele systeem te overdimensioneren verhoogt ook de financiële investering en de tijd die het kost om een overgang te maken naar hernieuwbare energie.”

 Dan hadden we het over 12 keer niet? Dat vergt minder dan die opslag bouwen? En lost het het probleem op?

“Het bouwen van zonnepanelen, windturbines, transmissielijnen, reservecapaciteit en energieopslag met energie afkonstig van hernieuwbare energie is evenmin een oplossing: ook dan wordt een overdimensionering verondersteld, want we moeten de hernieuwbare energie-infrastructuur bouwen die de hernieuwbare energie-infrastructuur zal bouwen.”

Klopt, maar lokaal, bij de productie faciliteiten. Dat is iets anders dan overdimensionering ter bestrijding van variabiliteit.

“Strategie 5” Vraag aanpassen aan het aanbod.

Tja, dat is een nieuwe versie van efficiency. Het voorkomt de transitie naar een gebuffered energiesysteem, iets dat logisch is want kolen zijn tegelijk een energie bron en opslag medium, windmolens en zonnepanelen zijn alleen brond, dus de opslag is een natuurlijke component.

“In dit scenario wordt hernieuwbare energie ideaal gezien alleen maar gebruikt als de zon schijnt of de wind waait.”

De auteur is niet van deze wereld. Ten eerste is dit natuurlijk al het geval, de wind en zonne stroom komt variabel op de markt, waardoor de stroomprijzen dalen en sommige bedrijven nemen dan juist af (bv. alluminium smelters).

“Als we daarin zouden slagen, dan zou er helemaal geen nood zijn aan energieopslag, reservecapaciteit, of een overgedimensioneerde transmissie- en generatiecapaciteit. “

Tja, maar dan loop je 1. de goedkope energie mis en 2. doe je niks aan het klimaatprobleem en zul je 3. toch extra zon en wind capaciteit moeten bouwen.

De auteur gaat door dat we omdat het bovenstaande ook lastig is, maar tekorten zullen moeten accepteren.

“Dat impliceert dat we afstappen van de verwachting dat we 24 uur per dag en 365 dagen per jaar zoveel elektriciteit hebben als we maar willen.”


“als het Verenigd Konikrijk 65 dagen per jaar een elektriciteitstekort zou accepteren, dan zou het elektriciteitsverbruik helemaal op hernieuwbare energiebronnen kunnen steunen (wind, zon, golf, getijden)”

Natuurlijk is bovenstaande opmerking onzin. De redeneerfout die gemaakt wordt is dat de grote getallen suggereren dat iets niet kan. Maar zo is het ook niet met kolen en olie gegaan. Niemand had benzine of diesel motoren, de aanvoer was er niet tot er steeds meer bronne kwamen en men de motoren en andere gebruikers van fossiele energie ging bouwen (in NL bijvoorbeeld het gasnet). Dat vergde enorm veel energie en grondstoffen, maar het gebeurde wel, omdat er mensen aan verdienden.

Bij wind, zon, golg/gedijden en geothermie (voor warmte en electriciteit) hoort opslag. Al deze industrieen zullen de ontwikkeling en beschikbaarheid van opslag oplossingen ondersteunen en als deel van hun expansie strategie hanteren. Elon Musk heeft voorgerekend dat er maar 100 Gigafactories op aarde nodig zijn voor alle stroomopslag.

Ransoenering van fossiel om capaciteit te gebruiken voor de productie van hernieuwbare bronen en opslag lijkt ons echter wel een goed idee!

Het stuk in LowTech Magazine is niet zozeer slecht omdat het een probleem schets dat wij niet valide vinden, maar omdat het een oplossing suggereerd die voorbij gaat aan de bijna niet te stoppen onafhankelijke initiatief rijkheid van onze wereld economie, waarin bijna elke deelnemer belang heeft bij goedkope energie op afroep. Er wordt gesproken van een ‘succesvolle strategie’ maar wat is dan succes? Dat je geen extra zon en wind of extra grid (wat je niet nodig hebt) of opslag hebt gebouwd? Iedereen snapt dat waar een behoefte leeft die zal worden beantwoord door productie. Daarom vinden we het artikel irrelevante onzin.

Stop op Uitbreiding Luchtvaart tbv Electrische Innovatie

De groei van het luchtverkeer loopt uit de hand. Steeds meer kleine luchthavens worden bijgeschakeld, en grotere worden uitgebreid om maar aan de vraag tegemoet te komen. De tickets zijn goedkoop ondermeer omdat er weinig belasting over de brandstof wordt geheven. Ondertussen zitten burgers in de smog en het lawaai.

Ten behoeve van de reductie van CO2 uitstoot zou men al die uitbreidingen en toename niet willen. Dit is zeer urgent omdat emissies die eenmaal zijn gebeurt heel moeilijk zijn terug te draaien. Het is zo urgent om iets te doen dat de politiek niet langer in staat lijkt het noodzakelijke tempo bij te benen, als het dat al zou willen. De Nederlandse politiek is iig nog in grote mate in de greep van de banken en fossiele bedrijven, die altijd geld genoeg hebben om iets te beloven, later, als niemand oplet.

Electrische propellor vliegtuigen zijn veel efficienter dan straalvliegtuigen, omdat een straalmotor op hoogte steeds minder goed werkt.

Intussen staat de techniek niet stil. We hebben niet alleen steeds efficientere vliegtuigen, maar tegenwoordig ook het perspectief van het electrische vliegtuig. Zo’n vliegtuig heeft batterijen aan boord, electromotoren en is stiller, schoner en efficienter. Kleine modellen zijn er al, net als vliegende auto’s, omdat je met electromotoren makkelijk een aantal in plaats van twee of vier kunt gebruiken. De belemmering is nu nog het gewicht van de batterijen. Deze zijn echter in constante ontwikkeling, met af en toe een doorbraak.

De meest recente doorbraak in batterij techniek is de uitvinding van solid state batterijen waarin het vloeibare electroliet vervangen is door plastic of een andere stof. Deze batterijen zijn niet alleen veiliger maar ze halen ook capaciteitswinst. Het is een kwestie van tijd tot batterijcapaciteit groot genoeg is voor een transatlantische vlucht.

Het is idioot om in de vijftien jaar die het nog duurt voordat er een getest groot electrisch vliegtuig is onze toekomst te verpesten met fossiele vluchten, zeker als het om vakanties gaat. De alternatieven, trein, auto, bus, hyperloop, zijn veel makkelijke klimaatvriendelijk te maken dan meer vluchten en meer/grotere luchthavens. Het is daarom geen gek idee om een moratorium op uitbreiding van luchthavens uit te vaardigen, tot electrische vliegtuigen beschikbaar zijn, danwel om de groei van luchthavens te koppelen aan investering in electrische vliegtuigen.

Goedkope vluchten ondermijnen de ontwikkeling van energie efficientere, schonere alternatieven

We genieten enorme welvaart door het benutte van fossiele hulpbronnen, maar deze welvaart wordt nu ook door deze bronnen bedreigd. Het is een goed idee eens een kleine pauze in te lassen voor we blindelings de economische krachten volgen. Deze hebben ons in de huidige rampzalige situatie gebracht, en zullen deze (als we de luchtvaart laten toenemen) nog rampzaliger maken. Een moratorium tot we veiliger, gezondere manieren hebben ontwikkeld om te vliegen lijkt ons fair.

How to “Pick up the Tab” of pollution, as the UN wants..

The above makes perfect sense. Pick up the tab, like a rock band that destroyed a hotel room, our pollutors, when it comes to CO2 or other harmfull ‘externalities’ need to pick up the tab. Pay for the restauration, cleanup. We have seen this in many oil spills, Exxon Valdes, the Gulf oil spill and most probably now in Athens, which has had a major oil diseaster nobody reports on.

Clean this up oil dickheads

But money on it’s own is not the best remedy against such events, whether it is toxins that kill small animals, bees in the US right now, or some mine who’s toxic basins have overflowed in a storm or the dams of which have broken, like it happend in Spain. All these events have and would cost enormous amounts of money to deal with, and these companies (for example BP) would be fighting the claims all the way, or simply fall over like TEPCO, go bankrupt, and go home.

Our money is carbon credit. If it doesn’t buy fossil fuels it is still useless, This is not an accident. Our economy is a system to distribute fossil resources (and indirectly all others) to maximize the cashflow for private banks and profit for private oil companies.

We have been writing about something we call carbon credit. This is our money. It has value in our economic system anyone who owns it can buy fossil fuels with it. This is the hidden fundamental assumption in our economy. Most people think of money in terms of some universal trading token, but it isn’t universal, there is an mechanism at work we need to aknowledge, and this is the competitive distribution of fossil resources through competition for money.

Just try to think of a world in which the Euro or Dollar bought everything except fossil fuels. You could work but you can’t heat your home with your paycheck. You could not drive anywhere. You could not buy bread because the baker needs something to heat the ovens. You could not buy clothes because the logistics of them is fossil based, the growing of cotton is fossil fuel based. You could not go to a movie because the projector needs electricity from fossil powered power plants. Even if the mix is shifting today, our credit system relies on fossil fuels, not renewables. That is why we call it the carbon credit system.

If you ask for money to restore nature you will recieve fossil credit, and using it will destroy the world some more.

“Picking up the tab” in this system, so lets assume for a second there’s no renewables at all, means the pollutor has to allocate money to buy fossil fuels to fix things. The diesel in the ships that clean up an oil spill, the diesel in the trucks that deliver the chemicals that clean the birds, or those that plant trees. In some cases there is no other measure but time, and then the victims are awarded money because their lives have been shortened or destroyed. That money is spend on trips and food and clothes, so on fossil fuels. In the end, as our economy dictates, no real progress has been made, we are stuck in a profitable near misery and mild stress. The disaster has been forgotten, the claim money stream blocked pending a court case the claimants can’t afford. The mentality of the industries that is causing these problems is really that grim.

So how to deal with pollution from industry in general. The key is to avoid the ‘economy’. The key is to allocate resources towards the creation of an independent capacity to restore and revive our environment or ecological resources. Up until now it has been done within the economic system, and this meant that certain problems (like the manure nitrogen problem) actually became economic cash cows, incentivising the distruction of ground water by dumping nitrogen on land, while also keeping up the nitrogen fertilizer cashflow.

Clean up companies need to be green themselves. So a oil spill cleanup needs to be done with electric ships, running on solar. To get these ships and the solar power plants to power them one can use claim money. The simple pattern is you green your clean up operation first, then clean up. Another is to reduce the need for whatever caused the disaster as a way to reduce the risk. So if a tar oil train derails and burns a town. use the money to lower the demand for tar, using renewables.

This does two things. First it creates an independent capacity to restore and clean up nature, that can operate and very low cost, because it has it’s own energy (and perhaps food) resources. Secondly the punishment of spilling oil is not selling more oil, but less in the future. The money which can run in the billions in each case, is much better spend in long term energy resources, in autonomous clean up capacity, than on temporary fixes.

When the Gulf oil spill happend, the solvent for the slick was tried and supplied kind of randomly. Without testing the health effects. It could be toxic, carcinogenic. It could be waste someone had in a pond that needed to be dumped somewhere, and now it was dumped on the oil spill and people where happy about it. This kind of screaming cowboy shit we don’t want anymore. Let all the disaster corporations pay into a claims fund that is used to run a clean energy powered taskforce that can do cleanups, restaurations, all the stuff you need, and make the money go towards scaling up it’s operations wherever needed, or desired. That is also a great way to start the #Roboeconomy 😉

The Rise of Extraeconomic Communities

We have written here about the Roboeconomy, or real life 3.0 in Max Tegmark speak. It is the economy that succesfully integrated human welbeeing, renewables and automation. We are in a transition to it now as automated systems are becoming easier to own by end consumers instead of producers.

The extraeconomy or an extraeconomy is a small economic system that lives outside the wider fossil credit (EU, Yen, $) controlled economy, and is thus not vulnerable to investors trying to buy it and take its resources.

Extraeconomic communities can exist within the physical wider economy, but are more likely to exist in locations where the fossil credit economy can’t reach, that is to say places that do not have any resources to export, that don’t easily support humans, so where the (fossil fuel) cost of keeping people alive and happy can not be justified by the generation of cashflow elsewhere. The middle of Australia or remote parts of Morocco or any old desert or remote forest village is usually already extraeconomic. These places allow poor lives on the scarce resources available.

But with renewables that can change. This is because renewables provide a resource, electricity (and heat/cooling) that has many applications. Alic Springs is actually trying to get a big solar farm, being resisted in it’s attempts. Now if it has that farm and the energy it provides it can in turn generate water, it can plant trees and green the area. It can shape the land with electic machines to become even more habitable. It can cool offices so the people can be more productive and comfortable. It can solar power any type of logistics it needs and thus become a fully functional community as if it was situated much more favourably. Why? Because the energy is free.

We can imagine that with a few component technolgies being

1. Water harvesting
2. Electric heavy transportation
3. Solar/Wind/Geothermal generation
4. Electic construction equipment
5. (optional) LED growing
6. A separate unique currency that can not be exchanged into fossil credit currencies

Any place with sufficient renewable resources can become viable. Internet, virtual reality and cheap electric transportation (including hyperloop and eflight) will make it acceptable, if not really pleasant to live outside big cities. Then people can tend to large areas of new growth forest, see their surroundings shaped by robots to maximize their enjoyment.

The pressure to survive on a fossil diet means we have to compete for the share given to us, as the amount of fossil fuel is limited. This is done by competing over money, by trying to make profit on our deals, making them inequitable by definition. The renewable resources we are now starting to use are spread out geographically, and thuse distribute production capacity and thus wealth in a way that with a low enough population density nobody needs to endure scarcity or compete.

The above described fossil scracity driven competition is also the reason natural resources are shipped across the globe, this pressure to make profit is nearly everywhere. Of course it is the people with adventurous minds that will be best fit to give way to this competitive pressure, but that’s not the reason why they do it. It’s financial desperation usually. That doesn’t need to exist in the roboeconomy, and will certainly not exist in the extraeconomic communities.

We think we should design an extraeconomic model community for use in different climatic regions. The purpose if them being ecorestauration without economic exploitation, so true addition of natural resources, carbon capture, biodiversity increase, species conservation and giving humans a happy life. The rules are thus:

1. Only use solar, wind, geothermal, wave/tidal energy
2. The community members are to increase biomass, capture carbon dioxide
3. The community lives of a one figure and shrinking percentage of the biomass it creates
4. No external economic involvement is allowed, travel/internet is of course free

A managing body that allows fossil credit to be allocated to the creation of extraeconomic communities, as well as to fund the external existence of community members can be created. It can facilitate the exchange of knowledge and human resources between communities.

Of course we do not need an iron curtain mentality, it is more as if one manages a number of companies, who also do not allow their employees to leave at will, work for other companies or sell assets randomly. In that sense some companies are already becoming partly extraeconomic, like Volkswagen using wind power, but a large portion of their cashflow as well as their product remain tied into the fossil credit economy.

An early 1900 cattle ranch in Australie as extraeconomic, if it did not deplete the land and would not have sold the cattle. Most US settlers lived extraeconomic, as most things one needs to survive have for the longest time been supplied by nature. What makes this extraeconomic concept different is that renewables add a wealth enabling factor in places that without it would be uninhabitable, and thus we can inhabit the most remote unbearable places and make them thrive. Of course it makes most sense to start with easy ones.

Of nobody wants to live in the middle of nowhere planting trees, we still have the Roboeconomic approach, so we use robots to do the job, with maintenance robots to keep things running. But we think the different effect of renewables on the geographical viability of communites will catch on, maybe we can even play a role.
