We’ve seen some pretty energy efficient homes here at Inhabitat, but houses that actually give back to the grid seemed to be a thing of the future — until now. Swedish designers are currently constructing Villa Akarp, a residence that aims to combine energy conservation, energy recovery and energy generation technologies. If all goes as planned, the home will actually produce more energy than it uses and provide the excess to the grid.
Imagine a building designed with the latest green technologies that also showcases innovative technologies of the future. Kind of blows your mind, right? Well that’s exactly what Spain’s green roofed and solar powered BTEK Technology Interpretation Center accomplishes. Designed by architecture firm ACXT, the new building is part of Spain’s Vizcaya Technology Park, where it will serve as an interpretation center that introduces student visitors to all kinds of forward-looking technologies.
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.
If you’re like the rest of us, you’ve got a pile of chargers left over from retired cell phones. You can’t use them with your new phone, but finding an innovative way of recycling the tangled up mass of wires can be difficult — quite the ecophile’s conundrum. Luckily, the International Telecommunication Union (ITU) aims to revolutionize the cell phone industry. The UN group recently unveiled its Universal Charging Solution, a charger that can be used in all future cell phone makes and models — as long as cell phone companies comply.
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.
Harvard scientists believe in the power of the good earth — literally. A team at the Boston-based college have created microbial fuel cell (MFC) batteries that derive energy from naturally occurring bacteria in soil. If the product takes off, the eco-friendly batteries could provide power for some of the 500 million people in sub-Saharan Africa who lack access to electricity.
As the United States government continues to drag its heels on passing climate change legislation, it’s encouraging to see folks in Europe making moves in the right direction. Last week, the French government announced it would dedicate $2.2 billion to creating a network of battery-charging stations for electric vehicles. The plan came as part of a much larger initiative that aims to move France towards a cleaner transportation system involving electric vehicles.
Creating the perfect solar cell (i.e. a cell that’s both efficient and cheaply produced) is certainly a work in progress. Researchers across the world have attempted to create cells from silicon, plastic and even human hair! Now, researchers at Cornell University came up with another concept: crafting solar cells from carbon nanotubes. Though still in the very early stages of development, if perfected, carbon nanotube-based cells could provide a more efficient method of converting light to electricity.
Fast food lovers may finally feel a little less guilty about getting greasy burgers. One New Jersey Burger King recently equipped its drive-thru with a speed bump that harvests electricity from cars that pass by. The speed bump is part of a pilot project from New Energy Technologies, and if all goes well, drivers could see energy-harvesting speed bumps at drive-thrus, toll plazas and even shopping centers.
The field of geo-engineering has launched all kinds of outlandish ideas for combating climate change, from dumping iron into the world’s oceans to shooting mirrors into space. A report published last Thursday from the Institution of Mechanical Engineers (IME) suggested that a forest of 100,000 artificial “trees” could be “planted” near depleted oil and gas reserves to trap carbon in a filter and bury it underground. The carbon suckers look more like fly swatters than actual arbors, but researchers say that once fully developed, the “trees” could remove thousands of times more carbon than a real tree.
Homer’s beloved character, Odysseus, may have garnered international acclaim by traversing the globe in a ship, but we think the famed traveler’s latest namesake represents a much hotter way to roam. Aurora Flight Sciences has unveiled a solar-powered concept plane, the Odysseus. The autonomous surveillance craft boasts the ability to fly above the earth for up to five years straight, deriving power solely from its solar panels.
Ever since the movie Chitty Chitty Bang Bang came out, fans across the country have awaited a flying vehicle that doesn’t produce CO2 emissions. While a flying car powered by magic really isn’t feasible (unfortunately), members of the Human-Powered Flight Club of the University College London’s Student Union (HPFC UCLU) are in the process of developing the next best thing: a hovercraft powered by pedaling. Dubbed the Steam Boat Willy, the craft recently completed a test run across the Thames River, and was even displayed at the UK Hovershow this July.
Plastic sure has gotten a bad rap lately — it takes petroleum to produce it, most kinds are notoriously difficult to recycle and it can leach harmful chemicals like BPA. But that hasn’t stopped researchers from using plastic for good — many are trying to make inexpensive, organic solar cells from the substance. Now, a team of University of Washington researchers has overcome a major hurdle is making those plastic solar cells a reality by creating a way to study plastic cell structure at the nano-level. The team’s findings could significantly speed up the plastic cell development process.
Recently Edinburgh-based company Aquamarine Power unveiled plans to install a new type of wave power system in place in the seabed off the Orkney Islands coast. Dubbed the Oyster, the system utilizes an on-shore base that is much easier to maintain than standard wave power designs, and the system is capable of operating at shallow depths, making it more consistent than systems that operate far out at sea. Each unit is capable of producing 300-600kw of electricity, so a commercial farm of ten units could provide clean energy for a town of 3,000 homes!
Everyone knows that trees combat climate change by absorbing carbon dioxide out of the air. Now, plant leaves are tackling global warming in another way — by serving as models for a technology that produces clean, renewable power. UC Berkeley researcher Michel Maharbiz, has worked with other scientists to develop an alternative energy system based on transpiration, a natural process where trees pull water from roots to tops, with liquid eventually evaporating off of the leaves. The system relies on artificial glass leaves to generate a steady stream of energy and is yet another example of biomimicry at work.
If you’re in search of a home that can withstand even the most powerful natural disasters, the solution might reside in the nearest tree. A team of researchers from five universities are currently working on ways to make wood earthquake-proof. If they succeed, the world may soon see cheap, sustainable wooden homes that can hold up even when earthquakes shake them to their cores.
The Big Apple’s known for its bright lights, but the city’s iconic luminescence also sucks up huge amounts of power every year. Luckily, a team of designers came up with a plan to keep the city’s lights burning bright by harnessing the power of its massive rivers. One of the most exciting entries into Metropolis magazine’s 2009 Next Generation Design Competition, Richard Garber and Brian Novello’s design provides a way to power street lamps using tidal power.
These days, it seems everything from rooftops to cell phones come equipped with solar panels. Now, huge cargo ships are the latest entities to join the solar power fray. The M/V Auriga Leader, now docked at the Port of Long Beach in California, recently unveiled an impressive array of 328 solar panels that will power the ship’s main electrical grid, making this the first ocean liner to be propelled in part by the sun’s rays.
Chickens may start losing sleep over more than Americans’ love of McNuggets. Chicken consumption in the US creates over six billion pounds of feathers each year. Previously discarded as waste, researchers at the University of Delaware are developing an innovative way to put all that wasted plumage to use — as fuel to power hydrogen fuel cell vehicles. If this technology was implemented in a fuel cell vehicle, it would cost about $200, as opposed to using carbon nanotube tanks (which cost about $5.5 million) or metal hydrides (which cost about $30,000).
It seems virtually everyone—from Wall Street bankers to small business owners—has been affected by the economic downturn. Now, the recession’s latest victims may be American cities. The Obama administration is reportedly considering plans to raze sections of 50 economically depressed US cities, condensing these towns’ shrinking populations and city services to smaller areas. The plan, dubbed “shrink to survive,” may seem kooky, but it could be big news for environmentalists: In many cases, bulldozed districts would be returned to nature via forests or meadows.
