Science, Big and Efficient

It looks like the folks at NASA caught a black hole consuming a star. Is it up on YouTube yet?

A bigger story has nothing to do with size. The old adage claims that it's what you do with it that matters. Solar cells have to be large because they aren't terribly efficient. And any electronics that are large are expensive. The Department of Energy has announced a solar cell with a stunning 40% efficiency. Such high efficiency cells are half of what we need to solve the energy problem. The other half is good storage solutions, by which I mean something not chemical batteries. Hopefully capacitor breakthroughs will follow, and then things will get really interesting.
