Algae is often touted as the next big thing in biofuels, but the slimy stuff could also be the key to paper-thin biodegradable batteries according to researchers at Uppsala University in Sweden. Eventually, the bio batteries could compete with commercial lithium-ion batteries.

Instead of just burning calories, why not use all that energy from exercising to power your MP3 player? The Dancepants Kinetic Music Player, a shortlisted entry in Designboom’s Green Life competition, lets you do just that by converting kinetic energy from running, hopping, jumping, etc. into electricity to power an iPod or other music player. According to the Dancepants designers, the product is a “100 percent interactive way to feel the value of energy on your own.”

The recent evolution of solar technology has been nothing short of amazing, and we are continuously impressed by all the products hitting the market that make it easier to integrate clean tech into our daily lives. One innovative company at the forefront of the solar energy bustle is Sulfurcell, the producer of a new kind of modular solar panel that add energy-generating capabilities to any building. The super-thin panels are entirely self contained, so they don’t require any substructure, and they can be applied to new buildings as well as retrofitted old buildings to provide a sleek look and plenty of power.

Think about how much trash goes into a bin in, say, New York City’s Times Square on a daily basis. What if all that garbage could be used to generate energy? That’s the thinking behind designer Haneum Lee’s Gaon Street Light – a lamppost powered by garbage!

The newest building concept to spring from the mind of eco-designer and artist Michael Jantzen is a testament to the power of renewable energy. His monumental Wind Farm Celebration Center is designed to serve as a visitor center and is very appropriately powered by an awe-inspiring 1.5 MW wind turbine that sprouts up from the structure like a blooming flower.

When it comes to teaching kids to conserve energy, positive reinforcement is the name of the game. Combine that with a cute and fun toy, and you really can’t go wrong. Case in point: Tio, an educational ghost pal and light-switch system for your tot that teaches them how cool turning off lights when we don’t need them can be. When lights are left on for only a short time, Tio smiles and is green. The longer kids leave the lights on, the madder Tio gets! Did we mention that you can use all the money you save on the electricity bill towards your little conservationist’s college education?

Throughout India there are many rural villages that are completely removed from the grid. With no source of power for cooking, light, and heating they currently must rely on firewood, kerosene or diesel for fuel. Now green jobs are blossoming throughout these remote areas as the Orissa Tribal Empowerment & Livelihoods Programme trains women and youth to become barefoot solar engineers. This brilliant initiative provides a bright future for the semi-literate and illiterate rural poor by teaching them to harness the sun through the construction of photovoltaic systems and solar powered lanterns.

Instead of acting as one of the most bland parts of city landscapes, what if manholes served a purpose? That’s what designers Cheolyeon Jo and Youngsun Lee propose with their “Eco Sign“, an electronic manhole cover that gives directions to the closest train or bus stop.

The Birds and the Bees have inspired one startup to send forth a hovering turbine. Green Wavelength, “committed to finding ways of applying nature’s solutions to our man-made energy problems,” presented its xBee prototype to an entrepreneurial buzz at The Perfect Pitch 2009. This biomimetic windmill sports 19-ft. wings of aluminum and carbon fiber that rotate to and fro — à la bumblebees, hummingbirds and dragonflies — to produce 1-10 kW of wind power suitable for homes and small businesses.

We’ll admit it: We’ve never totally understood Nascar’s appeal. I mean, come on, it’s just a bunch of cars going round and round a track like a zillion times! But the World Solar Challenge? Now that is one car race we can really get behind. The event, which started way back in 1987, features solar-powered vehicles created by some of the world’s top engineering colleges. Using the power of the sun instead of polluting fossil fuels, the cars race across thousands of miles in order to advance solar and electric vehicle technology — and to achieve the satisfaction of winning, of course.

Any one point on a busy street can receive up to 50,000 steps a day, so imagine if you could take all that foot traffic and turn it into something useful – like energy! A new product designed by Laurence Kemball-Cook, the director of Pavegen Systems Ltd., can do just that. With a minuscule flex of 5mm, the energy generating pavement is able to absorb the kinetic energy produced by every footstep, creating 2.1 watts of electricity per hour.

The problem with most built-in solar gadget chargers is that it just doesn’t make sense to stick your pricey phone in the sun for the whole day while you wait for it to charge. But the Regen ReNu modular solar panel takes care of that issue–the combination solar panel and battery pack attaches to the back of an iPod/iPhone dock or USB device for easy access to solar power. When you want to charge the panel, just remove it and place it near sunlight!

Rooftop solar panels are unlikely to elicit complaints from neighbors–they’re silent and relatively unobtrusive. But loud rooftop wind turbines? That’s where the virtually NIMBY-proof Ridgeblade turbine comes in. The turbine, designed by a former Rolls Royce turbine engineer at UK-based The Power Collective, boasts a sleek profile that is both powerful and visually pleasing.

Synch your workout with a little river detox, then rehydrate with a cup of the fresh water you just filtered. This people-powered water purification island, designed by Jakub Szczesny as part of the Synchronicity architecture and art festival in Warsaw, Poland, hooks up basic exercise machines to kinetically pump polluted water through four filters into overhead tanks that spill into a large drinking fountain at the end of the cycle. This floating platform on the Vistula River aims to empower citizens toward environmental clean-up, and apparently would work on any body of water with enough local bodies willing to pedal for their potables.

Scientific American recently reported that Sweden uses a pretty strange source for some of its heating fuel: rabbits. Stockholm has an overabundance of the cotton-tailed critters, and the hungry bunnies are decimating city parks. To cut back on bunny populations and create a greener source of heating fuel for Swedes, city employees round up the rabbits, shoot them, freeze them and then ship them to a heating plant where they’re incinerated. And yes, the thought of it makes our soul hurt, too.
