Fiddlesticks and horse apples!
We have been working on controlled fusion since 1953. So far, there has not been a fusion reactor design that produced enough excess energy to light up a single LED. There is good reason for this. Fusion, unlike every other reaction we obtain energy from is not a self-sustaining chain reaction. It's main selling point is its mos serious weakness. No, a fusion reactor could never runaway and overheat the way a fission reactor would, but just getting the damned thing to start is a major problem in and of itself.
Still, this is Lockheed's Skunkworks we are discussing here so I will take a wait and see approach, but I am not going to hold my breath. So far, the one design I have seen with any real promise can be found here:
