If any form of alternative energy actually worked, wouldn't the patent owners all be billionaires like Bill Gates and Warren Buffett?

Why does every single option have to be propped up by the government just to remain on life support?

Warren Buffett invested 5M in wind power and Bill Gates has placed millions in fuelcell, both of which are alternative energy sources. Does anyone know WHICH company, stock or shares that these guys have invested? Thanks!
