When we think of farming energy, we generally think of feedstocks like corn that can be processed into ethanol, or perhaps other plant life we can culture and harvest like algae. But don't underestimate the livestock; we've recently seen methane-trapping schemes that can power farms and giant cattle treadmills that turn idle dairy drones into power-producing machines.
Photographing animals in the wild traditionally requires a meticulously engineered infrared camera trap and good timing. Brothers Will and Matthew Burrard-Lucas, however, ingeniously attached a DSLR camera to a four-wheel-drive remote-control buggy, thus creating the BeetleCam.
Supercomputers and massive data centers carry huge energy costs when it comes to keeping their electronic components chilly. Now IBM is set to unveil its next big supercomputer, Aquasar, which keeps cool with a constant circulation of water at 140 to 160 degrees F, according to TechNewsDaily.
Bored guests at a certain Crowne Plaza hotel can now skip the pricey mini-bar and hop on an exercise bike, generate some electricity, and earn some meal vouchers. The hotel in Copenhagen started the free meal idea as a way to boost guests' fitness and shrink their carbon footprint, according to the BBC.
General Motors touted the automatic driving mode of its two-wheel electric car when it unveiled the vehicle last month in Shanghai, China. Now there's a video that shows the hands-off driving experience future commuters can expect from the EN-V.
Here at PopSci we're always looking for the best and baddest in robotics news. But this week -- National Robotics Week -- we'll be ratcheting up our coverage, highlighting some of the most thought-provoking, future-driven concepts in robo-tech each day.
What if we could use our pollution as fuel? That notion seems intractable within the current energy paradigm, in which so many of our pollutants are byproducts of our fuels. But it's precisely that idea that inspired Mexican artist Gilberto Esparza to create "Nomadic Plants," a working art-bot that uses polluted water to power its fuel cell and feed the plants and microorganisms living symbiotically within the bot's body.
A new update from John B. Carnett, PopSci's staff photographer who is using the latest green technology to build his dream home. Read more Green Dream posts here
It's been a long winter. Once the structure was complete, we started putting on the skin—a mixture of 100-year-old hemlock siding, white cedar shingles and a metal roof. All in all, I'm thrilled with the way it's coming together, and hope to be moving to interior work soon. The only serious snag? See that plastic over the window holes?
In the 236 years since oxygen was identified as a life-giving necessity, no scientist anywhere has discovered a multicellular animal capable of living without the stuff. Until now. Researchers from the Polytechnic University of Marche in Ancona, Italy*, have discovered three new species that live their entire life in an anoxic pit beneath the Mediterranean Sea.

Solar power sounds great: electricity from sunshine, for free, no carbon footprint. But solar panels often come with hefty price tags or require complex installations. Now lighter materials are making them less expensive and more convenient, whether you carry them with you or snap them onto your roof.
To take advantage of the strong winds that blow over the ocean, this gearless turbine uses a giant ring of magnets and 176-foot blades

There’s enough wind energy along our coastlines to power the country four times over, and the race is on to build the best offshore turbines to capture it. Manufacturers worldwide are experimenting with two techniques: ever-longer blades to harness more gusts, and simplified drivetrains (including new generators) that slash the need for costly repairs at sea. GE’s upcoming machine, slated to go online in 2012, will combine both into one package.
