Inhabitat's Week in Green: A modular airplane, and more!
Is the age of the solar-powered car upon us? Hanergy thinks so. The Chinese company just debuted four new vehicles that source all of their energy from the sun. Meanwhile, Clip-Air announced plans to test a crazy modular airplane that carries passengers and cargo in detachable pods. Eleven electric cars set off on a 15,534-mile race across 20 countries and three continents. And cycling infrastructure made huge strides as Paris launched its first bicycle superhighway and the US made progress on a colossal bike path connecting the entire East Coast.
Google invests in Africa's largest wind power farm
Google's big bet on clean energy isn't just limited to the US or Europe -- far from it. The search firm just promised to invest in Africa's largest wind farm, the Lake Turkana Wind Power Project in Kenya, by buying turbine maker Vestas' 12.5 percent stake when the farm is complete. Lake Turkana should generate 310MW of energy when all is said and done, or as much as 15 percent of Kenya's current output. That could not only help the country transition to green energy sources, but give it the kind of reliable electricity that's tough to find in the region.
Vestas Sailrocket 2 breaks at least one sailing speed record, says motors are for slowpokes (video)
Most of the boats achieving technical wonders these days have motors at their heart, even if they're completely fuel-free. Not so Vestas' Sailrocket 2, which just recently broke the 500-meter sailing speed record. A run across Namibia's Walvis Bay, just longer than the nautical mile the team wanted, saw pilot Paul Larsen officially reach a typical 54.1 knots (62.2MPH) with only wind power to carry him along. The necessary technological breakthough, as you'd suspect, comes mostly through the sail. Since the Sailrocket 2 doesn't have to turn in all directions, it uses an asymmetric wing whose optimized shape and lightweight carbon ribbing produce not only a very efficient power-to-weight ratio, but a seemingly logic-defying amplification effect: the sail catches wind generated by the boat's own speed, magnifying the intensity of any gusts until physics prevent going any faster. The kicker may be a slew of additional records coming in short order. As you'll see in the video after the break, Larsen has already hit unofficial averages of 55.3 knots (63.7MPH) over a nautical mile, 59.4 knots (68.3MPH) over 500 meters and 64.8 knots (74.6MPH) at peak speed. If we could reach that kind of pace on the water, we'd start to look at everyday motorboats as downright antiquated. [Image credit: Helena Darvelid, Vestas Sailrocket]
Vestas unveils massive 7-megawatt offshore wind turbine (video)
Building and putting any sort of offshore wind turbine into place is a fairly impressive bit of engineering, but Denmark's Vestas is truly going the extra mile with its new V164-7.0 MW turbine. Not only does it promise to provide seven megawatts of power but, as you can see above, each of the blades is longer than nine double-decker buses, which gives the turbine itself a larger total diameter than the London Eye. Of course, the company also hopes that there will eventually be not just a few of these, but massive farms of the turbines at sea (the North Sea, specifically), although that won't exactly happen overnight -- Vestas only expects to have the first prototypes ready by the end of 2012, with full production expected to begin in the first quarter of 2015. Head on past the break for a video -- don't worry, nothing like this happens. [Thanks, Alex]
Danish wind turbine eats itself
You know how we love wind turbines around here, but we love carnage even more -- so we can't get enough of this 200-foot tall Danish wind turbine shearing itself to bits after its brakes failed during a recent storm. The 10-year old windmill is the one of two different Vestas windmills to fail in Denmark in the past week -- the company is launching an investigation, but might we suggest selling tickets instead?[Via BoingBoing]
