life cycle

Last night someone told me about a great-sounding programme that had been on TV a couple of weeks ago, where a family moved into a house, but what they didn't know was that the electrics in the house were supplied by pedal power.

Out of sight, a team of cyclists provided all the energy the family required. When someone turned on a light or opened the fridge door or switched on the kettle, the TV audience could see exactly how many cyclists it took to meet that extra demand. The best bit, apparently, came when the wife put a cold chicken in the oven.

Anyone see this programme or know what it was called?
