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.
Not me. There is this guy from romania. He was in the DW news in October. And he made sort of a dynamo ran engine, that used weights. Weights were welded onto metal bars and they were just "free" spinning, based on Earth's magnetic field, creating electrical energy using magnets. Nothing else. And it's an early stage of development.
Here is another invention, that might give you more perspective - https://www.youtube.com/watch?v=CUOnYxRcDHU. A Bulgarian guy that lives in Utah.
There is such thing as free energy. It's what drives universe. And people have nothing to do with it. We just have to learn how to master it.
