USA Science & Engineering Festival 2010
Inaugural USA Science & Engineering Festival
October 23 and 24, 2010
Argonne’s Division of Educational Programs staffed a booth with the “Energy Bike”, which is equipped with a generator and a panel of standard incandescent bulbs, CFLs and LEDs.
Pedaling the bike with either bank of bulbs connected to the generator provided, firsthand, a graphic (and tiring) demonstration of how much less energy CFLs and particularly LEDs require. They also tried to power a hairdryer from the bike, a daunting task.
There was a line to ride the bike from 10am to 5:30pm both Saturday and Sunday. Over 350 children and adults rode the bike during this festival.
