"After previously investing in the company, Google has now acquired Makani Power, a green energy startup that is currently building airborne wind turbines. The acquisition was first reported in Brad Stone’s Businessweek story about Google X, and judging from Stone’s story, the team will join Google X. Google invested $10 million in the Alameda, Calif.-based company in 2006 and another $5 million in 2008. As far as we can see, this also marks the first time Google has acquired a company specifically for its Google X skunkworks."
