I was talking about the tests at Hydrodynamics, where there is a valve at the machine and also a nozzle at the end of the steam pipe, both of them restricting the flow out of the boiler. There is also a pump pushing the water (or steam) through. It is semi-pressurized, in other words. Not high pressure. The boiler had a pressure gage and Rossi should have one too. Rossi has a pump pushing the feedwater into the device. If he did this test, it would be good to restrict the outlet side a little, with a nozzle. That would solve this problem. The Hydrodynamics gadget is called a pump but ironically it does not pump. You need an aux. pump. I guess water pressure would work. The ones I saw had a feed tank and pump. The ones in carpet factories use wastewater from the production line. That's the whole point. It acts as a purifier, or a way to concentrate the gunk in the water, and it also reduces the factor demand for water. A normal gas or electrically fired boiler does not do a good job vaporizing wastewater. - Jed
