Increasing Local Albedo

One of my quests at the moment is to get an accurate idea of what local albedo changes will do to temperature. This is to make it clear for people what they can do to lower temperatures, which can be life saving, not only human lifes but of all lives. I’m working with a climate expert to find answers. The scale we work on now is still crude : 9km x 9km.

A random location in Pakistan

The above shows a region in Pakistan, with farmland next to dry uncultivated land. Possibly because of an underground aquifer or river, but also because of temperature differences. The albedo of green land and sand is similar about 30%, just in a different spectral regions. The model shows the temperature distribution under ‘normal’ conditions.

Normal temperatures

This image shows the sandy area is actually cooler than the agricultural area. This can be because the green shrub and black soil absorp more heat. If you increase the albedo of the entire area you get this result..

Enhanced Albedo Temperatures

This is the area with higher albedo 80%. The agricultual land is much cooler, it seems almost 100 degrees Fahrenheit! But we effectively turned the whole area in a polar ice region. I am working on a more detailed model. What would happen if you add alternating rows of white soil (calcium) between vegetation? If you know good models let me know.

A good question is also : If you increase albedo and the temperatures drop, does that mean it will start to rain? To be continued..

The Most Significant Climate Decision

This is a Roboeconomic post, which is about the now budding awareness of the fatal flaw in Capitalism. Repairing it does not turn it into Communism or Marxism. That is just the dumb Pavlov-response of the proponents of the current style of Capitalism. Any argument against it ends up with “Ah so you’re a communist!” just like any argument against what the state of Israel does ends up with “Ah so you’re an anti-semite”. You know you hit on a very strong ideological bastion if you get such a “there are only two choices” response. This is because capitalism in its current form is not designed to bring wealth but to protect the power of the banks.

The simple principle banks follow when doing business is to ask this question : “Does whatever it is increase my cashflow?”. If the answer is “Yes” the bank will do it (within the law mostly, but banks have done many things to find cashflow while breaking the law or at least moral standards). If the answer is “No” then they don’t do it! Wall Street banks have opened offices on tax havens to handle drug money, they opened loanshark offices in poor neighborhoods to extract onerous interest from already destitue people, they handled the credit card transactions of porn websites, banks generally don’t give a flying fuck about anything but increasing cashflow. I really believe that all misery in the world is caused by banks. 99% of all tragic content in the media is because of what banks did. I live in a nation anxious for homes and affordable energy and food because of what banks did.

This is not capitalism. It is just blind capitalism. It is not the process of increasing wealth of people. It is the process of increasing wealth for a very select nr. of people, those to gain from increased bank cashflow. The part where all the financing leads to more happiness (or could) is presented to us, as well as what happens if =people= make mistakes. Of course it is not people that do drugs that are wrong, it is those that produce the drugs and make it so that its the only affordable escape. It is not prostitutes that choose their seedy life, but the criminals that are somehow also making financial transactions that ship them to where they are totally disoriented and have no friends, because of migrant policies that the bank lakeys in politics have to promote in order to keep control over the biggest threat to their power, the less educated and less patient people in society.

It is clear that banks do not consider consequences as they maximize their cashflow. The obvious tweak we need to do to capitalism is to make sure they do. When it concerns climate change however we then discover that there is a dark relationship between fossil fuels and banks : The main source of cashflow for banks is the use of fossil fuels. In fact most of bank cashflow, if not 90% is related to consumption (burning) of fossil fuels. This is the reason the transition has to be financed by government or private investors, banks only step in when the immediate cashflow gain is just to big to ignore, which usually means there is a large fossil energy investment. The whole Hydrogen story that has no trouble whatsoever to find bank investment is exactly designed to secure bank cashflow and delay the transition to solar/wind/wave/geothermal

This is why any suggestion to change anything about the freedom of banks is immediately stomped on as ‘communist’ or ‘marxist’ or ‘socialist’. By whom? By obvious bank lakeys, fans of the banks, servants, people that feel exceptional because they have been chosen to sing praise to blind capitalism. People that all have no care for what happens after they die.

Making Highly Reflective Paint

To cool your roof or car or boat, you can paint it with special paint that will become highly reflective, so that the Sun is not able to warm it anymore. If you watch the video below from minute 13 you will see how it is done. In the first part he shows how to make a reflective paint but with risky material and waay more complicated.

The maker of the video above uses Acetone, which you should not handle without gloves! I may have given him this idea through a comment with links and am very happy he picked it up! 😉

How to make it:

  • Prepare Aceton and pieces of acrylic plastic
  • Put pieces of clear acrylic plastic in the aceton
  • Wait untill the acrylic is dissolved
  • Add a bit of aceton to a seringe, mixed with a bit of water 1 (water) to 4 (Acetone)
  • Add the water acetone mixture to the acetone with dissolved acrylic (amount depends on the dryness of the acetone)
  • Now you can apply it as a paint but wear gloves and do it outside close the bottle

The cooling effect in the video above has three causes

  1. Light reflection
  2. Emission by a material
  3. Thermal radiation

Reflection

When light is reflected it just bounces off the electrons, that absorb the energy of a photon and then throw out the same photon. This is why metals are reflective : Lots of electrons, and silver being the most conductive is also the most reflective.

What goes on in the bubble paint is that light bounces off spherical voids in the material multiple times until it leaves the material again.

Emission

Now every material has an absorbtion spectrum, meaning it will absorb light energy of certain frequencies and not of others well. This is because the energy of light in certain bands will push the electrons to another band, one it is used to occupying, and when the electron falls back the light is emitted again. This is what makes some materials emit light in certain frequency bands. The maker says that calcium emits in the infra red region that means the material can cool to outer space. This makes one paint cooler during the day than another, and this is what makes the paint he creates special.

Calcium has some emission bands in the IR, barium has less

Thermal radiation

The idea of radiation is based on temperature. It is based on the energy in the material that can cause photons to be emitted. Because of quantum dynamic principles the light can not contain more energy than is available, which then determines its color. This is why for example LED lamps have a ‘color temperature’ of say 2700 for sunlight and 4000 for bleuish (more higher frequencies). All materials radiate photons, and warm materials radiate infra red photons (we call it heat).

The neat thing about the paints is that thermal radiation happens no matter what, a black material radiates as much as a white material. This is why there is no difference between the paints at night : Its all just thermal radiation. The cool thing is (literally) that if the paint is on a heat conductive material it can suck heat from below and radiate it to the sky all night, but then during the day it will not allow it to heat up.
