Here’s a tip for the US government: how about you start getting innovative when it comes to energy, like Japan is?

Developed by Japan’s Sound Power , the FB-0001 platform generates electric power when the hundreds of thousands of station visitors step on its surface. In places where there isn’t enough room for windmills, these can do the trick.

As of now, nobody is sure how much power the devices are going to generate (the experiment lasts until Christmas). But could you imagine if stadium floors were replaced with these things? Or subway platforms in NYC? The possibilities are about endless!

If you’re interested, you can even purchase one right now for 50,000 yen ($550). You can also look at pictures of what they look like here .
