Green tech finds: Got some organic matter lying around?

Dead leaves? Grass clippings? Fruit and vegetable peels? Sure, you could compost them, or you could turn them into robot fuel or solar cells. Plus, a gadget for harvesting the power you generate while walking, and an app for showing off your gas and carbon savings from driving a plug-in vehicle.

Turn your Fall leaves into solar panels?: Or grass clippings, or other plant waste? It’s possible: plants do run on solar power themselves through photosynthesis. A new published report discusses advances in the field of “biophotovoltaics”; MIT physicist Andreas Mershin discusses the concept above. (via Cleantechnica)

The almanac that comes to your inbox: Thinking about starting a garden this Spring? Not sure when to plant what? Sprout Robot is an online service that will send you email notifications about when to start and plant seeds based on your location. (via Adam Sweet at Google+)

The poop-powered robot: The Bristol Robotics Laboratory in Great Britain has been experimenting for years with natural power systems for robots. Their latest, the Ecobot-III, would actually gather organic material (including human waste) to power its microbial fuel cell. It would also “poop” itself: “…at the end of the day, it gets rid of its own waste. It literally craps into its own ‘litter’ tray.”

Grad students design new “Eco-Fridge” concept: You won’t find these at the appliance store any time soon, but grad students from UC Berkeley and the Universidad Nacional Autónoma de México collaborated to create a concept for a refrigerator that uses 40% less energy. Sorry, fellow Americans: you may not find this one as useful as you’d like, as it’s designed specifically for Mexican households.

Show off your carbon footprint: Or, for that matter, your gas savings – the new GreenCharge app tracks all of the data from your plug-in vehicle that you’ll need to prove your green cred to the neighbors. (via Sierra Club Compass)

Walk your way to more battery power: Tired of your electronics batteries running out of juice, especially when you’re nowhere near an outlet? Take a walk: the nPower PEG harvests the kinetic energy you generate from walking, running, or biking. (via The Wall Street Journal)

The recycled razor: Feel a twinge of guilt every time you throw away a razor blade head? Schick’s got your back (a bit, anyway): its new Xtreme3® Eco™ razor has a handle made from 100% post-consumer plastic. (via @crispgreen)
