Mister Fusion

Fusion power is running behind schedule, at least if it's going to be installed on our flying cars before 2015.

Oh, no flying cars yet, either.

Researchers are still working on it, however (The fusion power, I mean. I don't know about the flying car part) and there is hope that one group working on a contract from the Navy might be about to produce a test reactor that produces more energy than it consumes.
