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.

Costanera Sur is a proposal for a vertical zoo in Buenos Aires that transforms a pile of rubble into a towering pillar of falling water. Designed by Visiondivision, the project aims to reclaim debris left over from the construction of Buenos Aires’ decades-old highways, is entirely self-sufficient, and could theoretically provide water and energy to surrounding structures.

Biofuels are often touted as the next big thing in airplane fuel technology, but solar power shouldn’t be discounted — as was recently proven by the team behind the Solar Impulse. The solar-powered plane just took its first test down the runway, and eventually the plane is expected to take a 20 to 25 day trip around the world.

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 beautiful thing about upcycled materials is that the end results often bear no resemblance to the original items. Such is the case with sculptor Kris Kuksi’s toy sculptures, which are constructed out of old toys, statues, and mechanical parts.

Imagine: a hurricane is barreling towards your house, but instead of hiding in the basement, you can stay safely and comfortably in your living room, all thanks to your X-Flex Blast Protection System wallpaper. It’s not a fantasy; the wallpaper, invented by Berry Plastics in a partnership with the U.S. Army Corp of Engineers, actually exists — and a single sheet is strong enough to stop a wrecking ball.

A person who drives 60 miles to work every day has different needs than someone who drives across town. So instead of designing electric cars to match the performance of petroleum-powered vehicles, researchers at Carnegie Mellon’s ChargeCar initiative think that EVs should be designed for individual commuting needs. To that end, ChargeCar hopes to create a so-called “commute ecology” based on crowdsourced data to develop EVs for different types of commutes.

Nearly 1.6 billion servings of Coca-Cola-branded beverages are served each day. Now some of them will be just a little bit greener now that Coke has announced the global rollout of its PlantBottle, a plastic bottle made from a blend of petroleum-based materials and 30% plant based materials (derived from sugar cane and molasses). The new bottles stand to cut down on carbon emissions by up to 25% compared to traditional PET bottles.

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!

Is there anything the iPhone can’t do? Researchers at NASA’s Homeland Security Cell-All program have brought the latest mind-boggling application to Apple’s phone in the form of a stamp-sized chemical sniffing device. The prototype chemical sensor can sniff small amounts of chemicals like methane, ammonia, and chlorine gas.

It sounds like something out of a science fiction novel, but architects at the Massachusetts Institute of Technology have a plan to build a massive digital cloud above the London skyline. The Cloud, which has been shortlisted in a competition to build a tourist attraction in the Olympic Park with a lasting legacy, would feature 400 foot-tall mesh towers topped with solar powered plastic bubbles that show images and data — i.e. weather information, Olympic race results, and spectator numbers. If built, the cloud could also be used as an observation deck and a park.

What if you could drive onto the highway, take your hands off the wheel, and sit back and read a book? That might not be as far-fetched as you might think if an EU-financed research project is successful. The project, dubbed SARTRE (Safe Road Trains for the Environment) wants to link vehicles together in eight-car “road trains” led by a professional driver. The project, which is aimed at commuters traveling long distances, could drastically cut travel time, congestion, and fuel consumption.

The Progressive Automotive X-Prize is heating up as the May 2010 start date approaches, and one of our favorite entrants is the eVARO, a three-wheeled plug-in hybrid from Future Vehicles Technology. The sleek electric vehicle can go from 0 to 60 MPH in 5 seconds and purportedly reaches 275 mpg under certain conditions. And for those times when there isn’t a gas station in site, the eVARO can cruise for up to 90 miles on pure battery power.

Instead of moving goods on resource-intensive trains, Spain-based technology company Novateq Guerrero SNL wants to build out a different kind of transportation network–one that uses super-powerful magnets to propel vehicles. Novateq has already developed a prototype of its system, which uses Neodymium magnets, or rare-earth magnets, as a driving force. The magnets are 9 times more powerful than conventional models.

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.
