Apple, other thin laptop makers pass latest round of EPEAT tests after summer mini-drama

Apple gave eco-friendly computer fans a brief jolt this July after it backed out of EPEAT certification, only to restore most devices just days later. While we can't say we're completely shocked at the follow-up, EPEAT has confirmed that at least one "ultra-thin" laptop from Apple has just cleared the verification process. The as yet unnamed system is more likely to be a Mac that had already earned the recycling-friendly rating in the past, such as the MacBook Air, rather than a sudden turnaround for the MacBook Pro with Retina Display. The look wasn't exclusively devoted to the Mac side, though -- EPEAT cleared Apple's computer as part of a wider test that also greenlit extra-thin portables from Lenovo, Samsung and Toshiba. We've reached out to get a more definitive list, but the approvals should ease the minds of those worried that ever-slimmer laptops are forcing us to give up our green efforts.

Reported new DARPA chief brings true geek, dash of green tech controversy

Reported new DARPA chief brings true geek, dash of green controversy

Running DARPA has always demanded a certain amount of tech-savviness -- it created what ultimately became the internet, after all -- but it may get an extra coat of green paint with a new leader. The agency has reportedly taken on Arati Prabhakar as its new director, and Wired notes that she has a lot more than just the agency itself under her belt. Along with going so far as to found DARPA's Microelectronics Technology Office, she ran the National Institute of Standards and Technology (NIST) and eventually signed on with Interval Research the venture capital firm that backed the solar power company Solyndra as well as numerous other green tech projects. That last decision has drawn a fair share of flak: Solyndra got about $500 million of public funding and still went under. With that in mind, an anonymous senior military staffer claims that Prabhakar wasn't involved in the questionable government loan and went through "extensive vetting," so it's doubtful that the funding will cast the same shadow over her DARPA technology investments as it did for the outgoing director, Regina Dugan. Even so, there will no doubt be a close watch over Prabhakar if the appointment is made public, both for those who want to keep her honest as well as for the potentially huge amount of insight into clean energy and general technology that she can wield.

Amazon becomes the latest retailer to sell the trendy Nest Learning Thermostat

Amazon becomes the latest retailer to sell the trendy Nest Learning Thermostat

Frankly, we all knew it was only a matter of time before the renowned online retailer, Amazon, would start offering the trendiest thermostat known to man. Joining the likes of Apple, Lowe's and, naturally, Nest's official site, Amazon is the latest shop to welcome the famed Learning Thermostat onto its shelves, with availability expected as soon as tomorrow (June 8th). As for pricing, that won't be changing much, which means you'll still have to shell out $249 -- though, you could see it hit your doorstep sooner without paying extra if you have one of those fancy Prime accounts. In any case, folks looking to grab one of these notorious Nest thermos can do so from either of the source links below.

Apple Store now selling Nest Thermostat: automated toastiness to cost $250

Apple Store now selling Nest Thermostat: automated toastiness to cost $250

Apple liked it so much, it's decided to let the Nest Thermostat share shelf-space in its bricks-and-mortar stores and online. Following rumors that Tony Fadell's latest project would appear at his former employer's store, it's now been confirmed with an online listing. Following some brief downtime on the Cupertino corp's retail site, the unit is set to retail for $250. Aside from sharing some design DNA, the thermostat unit can also be controlled from iPhones, iPads, iPods and Macs -- we presume that Android functionality is still there. Those that like their summers extra comfortable can hit the store link below.

Researchers use virus’s rogue traits to create electricity from motion

berkeley-labs-piezoelectrics-from-virus

Viruses are the swarming bullies of biology, but it turns out their alarming self-replication could one day power your iPod. We've seen them in batteries before, but researchers at Berkeley Labs have now coated electrodes with modified M13 bacteriophage, a harmless bacteria-eating virus, to create the first ever organic piezoelectric material -- which can convert force to electricity. The team explained that such a substance would be non-toxic, organize naturally into thin layers and self-regenerate, giving it a possible advantage over chemical options. In theory, by attaching a thin film of it to your shoes, power could be generated when walking, lending volts to the myriad electronics we pack around nowadays. To see a finger-powered video demo of our frequent-enemies making themselves useful for a change, stroll on past the break.

USC develops printable liquid solar cells for flexible, low-cost panels

USC develops printable liquid solar cells for flexible, low-cost panels

Solar cells are becoming more viable sources of energy -- and as they become more efficient, they're only getting smaller and cheaper to produce. Liquid nanocrystal cells are traditionally inefficient at converting sunlight into electricity, but by adding a synthetic ligand to help transmit currents, researchers at USC have improved their effectiveness. The advantage of these liquid solar cells? They're cheaper than single-crystal silicon wafer solutions, and they're also a shockingly minuscule four nanometers in size, meaning more than 250 billion could fit on the head of a pin. Moreover, they can be printed onto surfaces -- even plastic -- without melting. Ultimately, the goal of this research is to pave the way for ultra-flexible solar panels. However, the scientists are still experimenting with materials for constructing the nanocrystals, since the semiconductor cadmium selenide they've used thus far is too toxic for commercial use.
