His maps won’t get you from A to B, but Denis Wood’s diagrams definitely tell something unique about a given area. The illustration above shows a neighborhood’s phone, cable and power line setup. "We did a lot of walking and looking to make this map."

It’s surprisingly cool, in a weird first of the month kind of way.

Elan’s new Vero ENB-100 device is, according to them, the"world’s first solar-powered Bluetooth hands-free car kit. As long as there is available sunshine, you are good to go. At night, you have 15 hours of operation on a single charge. Get it in the UK only for £60 (or about $120).

It looks like a Pennsylvanian has found a way to allow saltwater to burn when it’s being exposed to the proper frequencies. Can you say new fuel source?

Though a long way from being commercialized, the new battery developed by Sony generates electricity using glucose, which is chemically broken down with enzymes. Apparently, you can power small electronics endlessly through a supply of glucose solution which you pour into the battery (I’m sure airline security will love that). While glucose-powered batteries are more environmentally friendly because they don’t emit carbon dioxide, at this stage of development, they’re not yet very practical. The output of a single glucose cell is 50 milliwatts; in the photo above, four cells are linked together to generate sufficient power to operate an MP3 player.

Cool, now if i can get a battery to run off my fat cells….now THAT’S an idea

It’s basically paper-based battery technology, using carbon nanotubes and an electrolyte embedded in the paper. It’s scalable, and could conceivably be bent into any shape. Connected to solar cells, it could provide on-the-go power to just about anything. With flexible screens and nano devices of all sorts, one day we’ll just roll our computers up and stick ‘em in our back pockets. All thanks to researchers like those at Renssalaer Polytechnic Institute.
