Human v. Fossil power

In a brilliant demonstration of the energy density of our modern (fossil) fuel sources,* the BBC TV show Bang Goes the Theory set about to power all the electrical loads of a British household using a warehouseful of stationary bicycles (and their human pedalers!) fitted with generators. Although we in the U.S. can't directly view the show's UK feed, they did provide this web-ready clip for worldwide players. Simply brilliant.

*Both UK and USA generate about 20% of their grid electricity in nuclear power plants. Uranium is a kind of fossil fuel, too. In any case, it's a finite fuel source, innit?
