I wasn't shure wherw to put this, to hho or gravity. It's based on the work of Tibor Simonfi and me, Dieter Marfurt.
Uses athmospheric Water circulation. Mechanics are tricky to build tho. May be useful for some of you. Needless to say, it's a weak Motor. Principle is hereby declared public domain.

hi.
is this some kind of steam engine ?

No, it stands over cold water. Paperstripes near the water pick up moisture quickly and deform(expand). Threads willl keep the axis a few mm on the right bottom side, resulting in a constant rotation. No more than 60 rpm expected. More of a toy. It is based on www.overunity.com/watermotor/ but even if I think it should work, a practical model failed due to mechanical misconceptions. That the model 1 I mentioned / linked to, works, that I know for sure.
These concepts work, the volume changes of eg. wood fibres, when exposed to moisture changes, these volume changes are indeed an untapped sea of energy. In the above design, there is only a 2D action, but when used in 3D, the power may be remarkable, considering that the effect lasts for months or years, contrary to when you just burn some wood.

Why does it have to be complicated, the age old water wheel would still be a very good, relatively cheap and durable solution.
At any river or stream one can build bigger or smaller ship water wheels, which can even be moved to an other location if necessary:

Modern materials (aluminum or simply steel) and modern electronics to turn the generated electricity into useful 220 V 50 Hz AC for distribution would make it very simple to build water wheels, even very big ones.
The many wind wheels now erected everywhere in Austria and elsewhere are a good concept. But I think that water mills (on ships on streams and rivers) or built as buildings (near a stream or river) would be cheaper and more easily maintained.
I see it often, simple and proven solutions are abandoned for reasons which are not clear to me. It does not have to be Mega-Watt to be useful. Small is beautiful, we have to learn that.

We all know water mills, you are way off topic. This thread is about standing water, that is the whole point.
"why so complicated?" ::)
Besides, at least here it is impossible to get a permission for such a water mill. Nice picture tho. But please stay on topic.

if river are avaliable everywhere, maybe there is no energy crisis issue.
and maybe Overunity.com never born ::)
