Or so says Montgomery Burns. Others, however, have learned what plants have known for billions of years, that the sun is a cheap source of energy. One such person is my cousin who, apparently, does this for a living. Here's his 5 minutes in the sun (ha!) on Fox.
On a related note, one benefit of attending MIT is that the alumni magazine, Technology Review, is actually worth reading. I wish I had a longer history of reading this periodical, so I would know if their predictions/hype are accurate harbingers of the future of technology. But if they are, we're not that far from generating a helluva lot of energy from solar. Analogous to computers, look at where we were 25 years ago. I really want to play Pogo Joe again, by the way -- I'm pretty sure there was a board entitled "Tennis, Antibody?" which is just hilarious.
