Spray-on Solar Power, Printers That Make Buildings & Generating Power While We Walk | 40Tech

Green tech isn’t waiting on the sidelines while the rest of the tech world progresses. Innovations are happening daily as scientists and visionaries search for ways to tap cleaner, sustainable energy sources. Some of the things that are coming out of those big, green-focused brains are nothing short of amazing, and the folks over at Inhabitat.com have put together a list of inspiring examples. Check out the highlights below:

  • Remember when solar panels were big, ugly… panels? Well, now there is a transparent nano-particle spray that can generate energy across the surface area of an entire building — or the top of a car, or most anything else.
  • Freaked out at the cost of building materials? There’s a 3D printer in development that can print entire stone buildings out of sand — at less cost and with less waste than Portland cement.
  • What do you think about floor titles that convert the kinetic energy you expend walking into useable energy? Wouldn’t that be a neat way to power a subway system? What about mini-generators in the soles of your shoes? You know, to charge your cell phone or power some blinky lights while you run?

Me? I think this all sounds very, very cool. My one concern would be the energy needs and waste that would result from mass production of this kind of tech. After all, if you kill 10 fish in a pond just to catch one with a “humane” hook — next season will be rather slow, yes?  (* /metaphorical-wisdom *)
