I know this is a science forum and not a forum for conspiracy theorists but I have always been intrigued by the idea of a world where everyone has access to 'free' energy. What impact would it have on the world? Would it solve 99 per cent of all problems?
There will never be "free" energy. You'll always pay a fee to the power company to maintain the plants and transmissions lines, regardless of what the power itself costs to create.
I think the term you might be looking for is "unlimited" energy?
