The Rai is a big exhibition building in Amsterdam....
Daobra,
Some of the old dieselengines had the funny thing that they could run on water, directly....
I heard this from more then 1 person. Myself, i never had the change to test this.
Maybe they ran first on diesel and switched later to water.
About the cell of Thewaterenergy person, i cannot see anything else then you do.
The guy states that it runs in resonance....
He fills an empty waterbottle with steam as a way of measurements......
So, not sure what he is doing....but it looks like some kind of pre-commercial steps....
