Can one idea be energy's holy grail?

Michel Laberge quit his job to invent a "glorified jackhammer" that he hoped would save the planet. That was 10 years ago.

Now, investors are betting more than $30 million on that jackhammer idea, which may yield a holy grail of energy -- a safe, clean and unlimited power source called hot fusion.

Laberge is trying to do something that no one has ever done: create a controlled "net gain" fusion reaction that creates more energy than is required to produce it. It's the same process that powers our sun. If it works, it could solve huge problems like climate change, the energy crunch and reliance on foreign oil.
