Meet The Energy-Saving Gadgets Of The Future IRA FLATOW, HOST:
This is SCIENCE FRIDAY; I'm Ira Flatow. Imagine walking through
Times Square, and every step you take it converted into a tiny
electric current by the special pavement underfoot. Now multiply
by the third of a million people who walk through Times Square
on any given day. Wow, it could be a pretty awesome source of
renewable energy, right, perhaps enough to power all those neon
lights and flashing billboards. Well, maybe a little while yet
to go before the sidewalks of New York are electrified, but one
team of high school students, inventors, are already working on
the idea, and they've built a prototype sidewalk tile that
converts your footsteps to watts, that's with two T's, earning
themselves second place nationally in the Siemens We Can
Challenge the World Challenge. Those teen innovators and a few
more are joining us to share their stories and inventions, many
of them energy-saving gadgets, and they're all created by these
young scientists. L
