Fusion energy is the ultimate solution for the Earth's energy problems - if we can make it work. We still can't, but a major step forward was announced. Scientists at the National Ignition Facility have gotten more energy out of the fuel in their experiment than they put in. We're still a long way from a commercial machine, but this event caused some jubilation among physicists, not normally thought of as party animals.
I'm hardly a physicist, and I don't know how close we are to fusion. But as long as we are making progress, it's worth the investment.
Unproven claims from certain people selling something called the e-Cat (never tested without its inventor present) notwithstanding, this is the path to the future.
