I remember watching a documentary about electric cars and this guy had a engine that was performing close to gas engines in some areas and surpassing it in other areas. It was extremely quiet and there was no messy engine, and hardly any engine upkeep.
This efficiency, would reduce multiple companies profits and the killed this engine during the market testing. People were using these cars and LOVING them. And then these companies lead by the gas industry basically got them all repo'd.
Sucks man, I think this same guy, (or maybe a different one) invented solar panels that basically look/replace the shingles on your roof (or part of it) and they were so efficient that it would power every need in the house year round, storing energy for the night.
He got stopped as well but he has it on his on personal house in Sweden or something somewhere and was giving a tour of it.
