The Power of Sun

The other night this TreeHugger happened to catch part of a TV documentary, simply called The Sun. We think it came via the BBC, but can't seem to locate an original link for you. Suffice to say, given all the talk about the need to rethink our energy needs beyond oil and coal, we were quite taken with a few of the mindbending stats. Apparently the sun has enough of a fuel store to keep on shining for another five billion years. And it's energy output is estimated to be 386 billion, billion megawatts. Or put into more meaningful language; "in 15 minutes the sun radiates as much energy as mankind consumes in all forms, during an entire year." No wonder it is the nuclear reactor that William McDonough most prefers.
