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.

Early dutch rainmaker in action

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.

Herre Rost van Tonningen. pointing to his project in South America

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!

Looking at the RO setup. It has to be said hydraulic pumps are cheap!

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.

The Solteq turbine, now probably broken down.

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.
