The world needs a new source of energy, an unspillable source.

Why isn’t more studied about Nikola Tesla?

Can anyone tell me if there is anybody picking up where Nikola Tesla left off when it comes to AC current, and his many other inventions? And if all of our homes did run on AC current, how much would that affect the environment if we had clean ways of producing it for the masses? I think that there is just as much that we can learn from past inventors as much as we have present.
