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 -

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.
And again, I ask, why don't you make one of those yourself? Why are there dozens, if not hundreds, of these inventions, and not a single guy shares the technical details or instructions for how to build it, and no two people ever seem to build the same type of device?
And before you say "money," we have crowdfjnding and loans. Raise or borrow some money, build one at home, use it to power your neighbors' houses and charge them for electricity, then use that money to pay back investors or bank. Very easy, but no one in the entire world is doing it. Why?
