Yesterday, I wrote an article about the energy we could get out of a fusion reactor in development. Today, it’s about the energy we could get from a fusion reactor already in service: the Sun.

Solar power lacks the flair of fusion, and I’m afraid the story of a plane that cruises at 43 mph probably won’t do much to help that along, but there’s a lot to the Solar Impulse that captures the imagination. There’s its magnificent wingspan, for instance:

It’s empty weight is about the same as your car’s. Think for a moment about the brilliant design and fine construction keeping the weight down must have required. There’s no two ways about it – just the size-to-weight issue makes this a marvel of engineering.
