How many people pedaling bikes does it take to power a big-screen TV?
About 2 people pedalingA big-screen TV needs about 150 W, and a rider makes about 100 W.
It takes about 2 people pedaling.
How we worked it out
A big-screen TV needs about 150 W, and a rider makes about 100 W. Each rider keeps up a steady 100 watts, like a brisk ride. Real life adds a little friction and waste, so treat the number as a solid ballpark rather than a lab result. The constants behind every experiment are on the science page.
Watch it happen
This was one of the five experiments in It Took #10. In the game you guess first, then the experiment plays out with your number: too few and it fails, too many and it overshoots.
