Hasta La Gadget!

Solar may be the green energy source that’s been hogging the headlines lately, but there are other fossil-fuel free ways that can help meet society’s electrical needs. One of these is tidal power, and the US is set to start harnessing the ocean’s electricity-generating potential this summer with the TidGen Cobscook Bay project — the first such commercial project in the States. Located just off the coast of Eastport, Maine, turbines will be placed in 50-100 feet deep water to take advantage of the 100 billion tons of water that flow in and out of Cobscook Bay each day. When the project goes live, it’ll feed into the public power grid and generate enough juice to power between 75 and 100 homes, and the plan is to eventually install enough turbines to generate 3MW of power — which should cover the needs of over 1,000 homes and businesses. There’s more info, plus plenty of political self-congratulation in the source below.

It’s been a great week for two of our favorite things over at Inhabitat: LEGOs and Star Wars. First, a group of LEGO builders from LEGOLAND Windsor built the tallest LEGO tower ever, snatching the title back from South Korea and returning it to the UK. Then, using 152,455 LEGO bricks, Rolls-Royce built a half-size replica of the jet engine that powers the Boeing 787 Dreamliner. In one of the most ingenious LEGO constructions ever built, LEGO pro Rene Hoffmeister built a barrel organ that plays the Star Wars theme song. And in other Star Wars news, we reported on the renovation of Luke Skywalker’s boyhood home in Tatooine (actually it’s in Tunisia). And finally, we shared a photo of this 7-centimeter-tall origami Yoda — the most adorable bit of Star Wars memorabilia ever made.

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.
