Last night, Stephen Colbert's guest on The Colbert Report was Elon Musk. And, after Musk dodged the question about his inevitable slide into supervillainy, he talked a bit about the future of Tesla, SpaceX, his plan to go to Mars, and a few ideas that are somehow even more ambitious.

Musk told Colbert that he and SpaceX are focused on reusability for space flights: building a rocket that can take off, land, refuel, and take off again is incredibly important. He also says that he'll be sending people to space in two years. He talked about Tesla's desire to personalize your car, and told Colbert that he named his Old Faithful. But the most interesting part of the interview came when Musk asked Colbert what he wanted to see in the future. Colbert said he doesn't want cables, he really wants a jetpack, and then said he wanted wireless power to be everywhere, so we'd never run out of power again.

Musk's response? "Yeah, we'll do it." If we've learned one thing about Elon Musk over the years, it's that he probably means what he says.
