Re: I know there is no such thing as 'free energy' but what if it was possible?
I watched this documentary about a European engineer (I think Romanian) who invented an electrical generator, that uses the Earth graviational field to produce 200W of electricity. All materials used were basic - rotors, weights, dynamos etc.
This is called a dam.
No. A dam uses water, not gravity and costs billions. This thing you can make yourself and uses no external fuel or another costly force to run. But it's not surprising that there is lack of funding for this kind of inventions.
You can make a cheaper dam for 200W output, and if the dam's not using gravity then the water wouldn't be there right? I was thinking the dam uses earth .. now you got me confused.
