## Gravity Cooling

As the world warms water that evaporates is going to rain down less easily. This puts more water vapor in the atmosphere, which absorbs heat from the Sun, warming the atmosphere more. This can be a positive feeback cycle with a seriously problematic end.

Luckily nights cool the atmosphere so that rain can start to fall. Most of the times though it will reevaporate as it falls, so no rain after all.

One factor in this process is the absorption of heat by the falling raindrops. The bigger they get the harder this is, I have no absolute numbers. If what is falling is ice, a ball of ice then the ability of the atmosphere to heat it and evaporate it as it falls is reduced, which is why we get hailstorms : The ice reaches the ground.

If a ball of ice falls from the clouds this is a very good thing, because heat has been shed somewhere up there, and a volume of water under 0 Celsius was returned. Of course it develops kinetic energy as it falls. The question whether a ball of ice really cools the Earth depends on the cold tansported minus the heat donated from the impact.

The energy needed to heat one Kg of ice 1 Degree Celsius is 2 KJ. So if 1 Kg ice is -2 Celsius it absorbs 4 KJ to warm it to 0 degrees. Melting ice into water requires a lot of energy though. 334 KJ for 1 Kg, that is quite a lot. So an iceball of 1 Kg of -2 Celsius absorbs 338 KJ of energy while melting.

The energy of a falling Kg of ice depends on how far it falls. The enegy is mass x gravity x height, so 1 Kg x 9.8 x 6100 meter (estimated average origin of hail) = 5978 Joule so that means an 1 Kg ice ball coming in from above cools the ground about ~332.1 KJs worth. Not bad!

So we can see a convection cooling cycle to ~6100 meter that will cool the ground. Gravity is pushing heat out of the system this way. If you make active convection zones, where you make it more likely water evaporates you may be able to shield sunlight from warming other water and jettison the heat at the surface as the water returns frozen.

One can envisage a controlled convection column say at sea, with high absorbent layers to heat the air at its foot thus pulling in air over the water which increases evaporation. The whole thing looks similar to a solar updraft tower as existed in Spain for a while (it contained a wind turbine at the base of the chimney worked like a charm, was profitable but was broken down anyway as solar tech was reinvented several times to delay its advent).

There are other important facts most people don’t know about rain, hail, water vapor in the atmosphere. It seems that as the effect of water vapor was suspected to be significant it was -not- modelled very accurately or at all in climate scenarios. Now we need to learn more because we want it to rain, not to get cyclones or tornado’s, no huge hailstones etc. We will have to get a grip on weather as well as the climate.

Hailstorms should also be triggerable but more on that another time.

## Making Water with Wind

Or how banks killed a perfectly good water solution

In 2013 I first wrote about a company called “Dutch Rainmaker” that developed a wind turbine that generates water from the air by cooling it. It grew out of a science environment into a demo and soon there where several small turbines running in Holland making thousands of liters of water every day.

You may wonder “where is the company now?”. The answer is nowhere, or at least not in any way making products and selling them. The reason is the reason why so many other companies got “killed” or “frozen” in the years I tracked them, because BANKS want CASHFLOW. In this case the invention was a direct threat to RO desalination systems.

Below a video of the early system, which was an electric turbine that powered a compressor and cooling system that cooled the air until water condensed out of it.

I tracked this company which is by now quite old, as was its original owner, the inventor. the above design was quite simple, so the turbine and tower cost about 10.000 Euro to setup. A perfect product to spread rapidly acrosse the globe. However this was not to be.

The first principle we have to accept is that if banks get a chance they will kill low cashflow products. This they can do in many ways, by underinvesting, by overinvesting, by injectnig a shit CEO, by putting the patent in an inactive company. Any way that gets the original owner to give up control over the idea. This is not a conspiracy theory, this is simply good business sense for BANKS, who don’t care about humanity as a whole.

Later itteration of the Dutch Rainmaker

As you can see in the video above the device has become more complicated. Rather than an electric generator the nacelle now contains multiple hydraulic pumps that are driven by a friction wheel. Many parts that can break or leak. How does this happen? Well, the maker has to be able to patent something to gain investors. And a conventional turbine is not patentable (in this context). So there are two options : The market ignores the product completely (with some help from investors/banks) or the inventor makes the product patentable. The utility of the product does not matter. Banks don’t care about humanity.

I tracked this company and in 2016 I decided to visit (and was allowed) the office that had moved to the high North of Holland. There I spoke to Herre Rost van Tonningen (never asked if he was related) who showed me his setup. Now there where hydraulic pumps in the nacelle, and on the ground the pressure was used to drive Reverse Osmosis pumps!! A completely different concept. Allinged with what banks like though, not disrupting the RO/desalination market!

Herre explained he was going to demo his version on a South American island because water is much more expensive there (see economic motive, maximizing cashflow for banks). I don’t know what happened to it. Will try to find out.

But what happened to the real Dutch Rainmaker? Well, its idea and related patents are owned by a company called “Rainmaker Worldwide” which has a nice website. There is a penny stock called RAKR worth \$0.0025 today.

The company announced its going to cooperate with Mirand Water (purification) systems, which does work for the below companies (so we’re talking toxic waste water treatment). Furthermore there are changes to the company structure and ownership. What is not happening is the construction and deployment of Dutch Rainmakers to provide cheap water to farmers and other people around the world using a low cost barely patentable system. Reverse Osmosis which requires high pressure and energy, and thus causes high cashflow, has been protected.
