Shell backs Alphabet's power-generating kites in latest renewable bet
Alphabet is turning yet another one of its X projects into a business, but this time it's enlisting the help of an unusual ally. Makani Power, a venture making electricity-generating kites (see above), has become a full-fledged subsidiary of Alphabet thanks in part to a minority investment from Shell -- yes, the fossil fuel giant. The two hope to shift the technology from the land to offshore, where winds are stronger. They're betting that the kites will be easier to deploy than conventional wind farms, since they could deploy with floating buoys instead of requiring platforms that reach down to the ocean bed.
World’s first floating wind farm powers up in Scotland
The blades of five huge turbines have begun spinning on the world's first floating offshore wind farm, located over 15 miles off the coast of Peterhead, Aberdeenshire in Scotland. First Minister Nicola Sturgeon is cutting the ribbon on the renewable energy site today -- presumably in an on-land ceremony -- which is capable of pumping 30 megawatts of clean electricity into the grid. In more human terms, that's enough to power approximately 20,000 homes. The turbines of Hywind Scotland stand 253 meters tall in total (around 830 feet), with 78 meters (256 feet) of that bobbing beneath the surface, tethered to the seabed by chains weighing 1,200 tonnes.
ICYMI: Floating wind farm, autonomous robot delivery & more

Scotland's coast will be home to Europe's largest offshore wind farm. And Georgia Tech researchers are studying fire ants to try to engineer self-healing materials.
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]
Baryonyx to build largest offshore wind farms in the US, power massive data centers
Uh oh Mr. Pickens -- looks like you've got some competition down in Texas. With the aforesaid energy baron scraping plans to plant 687 massive wind turbines in Texas' panhandle, Baryonyx has stepped in to do the honors via a slightly different project. Just this past week, Baryonyx won a bid to create a pair of sizable offshore wind farms that Jerry Patterson -- Commissioner of the Texas General Land Office -- says "could be the biggest offshore wind farms in the nation." Additionally, another lease was granted for a prospective wind energy development in the panhandle, and now the company is eager to get going on the green energy gigs. The best part of this whole plan involves that actual purpose of the turbines; aside from providing juice for grids, they'll also be used to energize forthcoming Tier 4 server farms, with a minimum of 750 megawatts of power being pumped to two coastal areas all the while. Ma Earth would be proud.[Via CNET]Read - Baryonyx announcement [PDF]Read - Patterson announcement [PDF]
UK wants every home wind-powered by 2020
In an ambitious scheme than even industry proponents seem skeptical of, Britain has unveiled plans to power every home in the country via off-shore wind farms by the year 2020. Right now the UK produces approximately half a gigawatt through this method of power generation, enough to provide 2% of the country's electricity, but nowhere near the 33 gigawatts called for in business secretary John Hutton's proposal. According to the British Wind Association Trade Group, while more offshore farms are always welcome, it is far more reasonable to expect a 20 gigawatt output by 2020 -- the bottleneck, apparently, is in procuring an adequate number of turbines. Another issue is the economic cost of wind power, which continues to exceed that of fossil fuel-based alternatives; luckily for the Brits, favorable exchange rates should help them pick up some American-made turbines on the cheap.[Thanks, WebOn]
