Pocket power.

Why shoud you care about being green if there’s nothing in it for you?  The reason you should care about renewable energy is that it gives you lots of ways to start generating your own energy to power all those energy hungry gadgets you love.  You won’t even notice that you’re doing it thanks to future technology.

NASA Makes Longer, Straighter Piezoelectric Nanowires in Microgravity

Microgravity provides nano solutions.

Piezoelectric nanowires are the stuff that make power-generating pants a possibility, and that prodigious potential has drawn the attention of NASA. You see, self-powered spacesuits are awfully attractive to our nation’s space agency, and a few of its finest student researchers have discovered that the current-creating strands of zinc oxide can be made longer and straighter — and therefore more powerful — when freed from gravity’s unrelenting pull. That means nanowires grown in microgravity could lead to higher capacity batteries and the aforementioned juice-generating interstellar garb…

Transforming the Wind’s Vibrations into Electricity

As a renewable energy resource, wind has lots going for it – but one major downside is the cost to set up the wind turbines themselves, not to mention the problematic visual impact and the noise pollution it generates (often likened to a small jet engine, especially for those living close by). However, undergraduate students from Cornell University’s Vibro-Wind Research Group are working on a space-saving prototype that will harness wind power more cheaply and efficiently – by transforming the wind’s vibrations into electricity.

Electronic Gadgets Could One Day Be Powered By Blood Flow

This image show an experimental test of piezoelectric nanowires that harness a hamster’s wheel-turning energy into usable power. 

Power generated from flowing blood, simple body movements or a gentle breeze could one day be converted to electricity to charge iPods, cell phones and other personal electronic devices.
