Hey Nutopians,

I have had the oportunnity to build a few \’Ram\’ pumps here in Costa Rica. They are very simple because they use the force from cavitation(implosion) as the motive power for the pump. The one I have built is online at Clemson.edu and costs roughly a hundred dollars to build correctly. This particular model would pump 1/8th of my water supply 200\’ above the pump, which was roughly 40\’ below the source using no electricity.
If you have ever turned a valve in a old house and heard the pipes shake this is cavitation. Essentially, water implodes when it\’s flow is abruptly stopped. In this case, our pump has two valves in sequence, one flap valve and than a spring loaded pressure valve. As the water supply fills the cavity between the two valves the pressure depresses the spring which automatically closes the overflow on the flap valve. The magic occurs on the front side of the check(spring) valve where there is a pressure chamber to amplify the shock wave of the implosion.
Refer to the internet for animations.
In my area these type of pumps have been operational for over 40 years. There seems to be two major drawbacks that to me can be overcome easily. One is they emit a large ping every second or so. This can be nerve racking especially in a tranquil forest environment. Two, the shock wave usually destroys the down pipe into the machine. Most of the money in set up should be securing the pump and the pipes leading into it. The shock wave travels all the way back to the source of the water!
Obviously these pumps are for areas where there is an abundance of water as they only can send a small volume vertically. We usually set them up so the overflow is directed into a pond. In my opinion these pumps do not jeopardize the structure of the water because the water is only pressurized for a split second and than the implosion converts that into kinetic energy. Schauberger was big on using temperature to verify the coherent quality of H20 and these pumps have a cooling effect.

Hey Chris can you tell me more about how you charged your water? Did you charge in a kit or in the cell itself? What\’s your charging circuit?

I have researched these buildings quite a bit. They were my introduction to domes in the 80\’s. We are working on how to build these without the need for the balloon. I have built two geodesic domes from split bamboo and we can apply a sheathing called concrete canvas for a incredibly strong and inexpensive building. We can also build vaults in the same way.
