Sounds like it was really quite "low-tech." The stationary bikes spun an old car alternator, which recharged a battery. The battery
was used for whatever they had running in the office. (If I'm wrong, please correct me... I doubt a car alternator could provide more than maybe 1000 watts. Which wouldn't be enough juice to power a toaster or a hair dryer. They must've really been on "impulse power" in the office all day. But it's some interesting symbolism.)Here's something for you to consider.
If it takes the efforts of 9 cyclists to spin a car alternator, how much bike-power would it take to spin the alternator, and maybe an A/C compressor... and also actually propel a 4000-pound vehicle down the street? It boggles the mind to think how much energy the typical car-commuter requires, to get from Point A to Point B. (And multiply that by the millions of car-commuters out there, on any given day.)
