Q: At the Ride the Drive event last Sunday in Madison, the music stage on the Capitol Square at the top of East Washington Avenue was powered by people riding stationary bikes. How did that work?A few more details at the Wisconsin State Journal.
A: The electricity needed to power the stage lights and sound system for the four-hour concert was provided entirely by people pedaling 12 bikes, said Dan O'Brien, a co-owner of Power by the People, the Waukesha company that provided the system. The bikes were hooked up to generators.
"There was no connection to any outside electricity," he said. "It was all humans."
