Possible Free Energy

So this guy right here claims to have created a nuclear fusion reactor at his home that produces more energy than is put into it. Thus free energy. Awesome. :D Even if he hasn't actually done it, it's still cool. :)

Just a thought, could this be the way to power space ships to the ends of the galaxy and beyond? I mean, it seems that one of the major challenges of getting a spaceship really far out there would be fuel, but if there is an energy source on the ship that can produce unlimited energy to drive the ship... Well, that's just plain awesome. Haha. :)
The thing that makes this all so much cooler is that this is just a guy living his dream and inventing just for the love of inventing. Kudos to him. Maybe there's something we can learn from how he lives.
