Lockheed -Martin is announcing that their research into fusion reactors looks like it's about to pay off. They have a small prototype which is working as predicted, and seem to think they can have a scaled up version (100Mw) turned on in about 5 years.
This is the humanities holy grail, in its own way. For physicists, it would be discovering the Hamster-Boson and presenting a jar full as party favors at the big Physics convention. For the rest of us this is taking something the physicists have discovered and turning it into something practical and salable.
Others including Polywell Fusion also claim to be hot on the trail of a working fusion reactor, so perhaps we'll see something actually working in the next 5 years or so.
It's atomic, so the Greens will oppose it.
