Makani Power is an Alameda, California-based company that developed airborne wind turbines with the support of Google X and the U.S. Department of Energy office of ARPA-E. Makani is a leader in the development of airborne wind power extraction systems.[1] Makani was founded in 2006 by Saul Griffith, Don Montague, and Corwin Hardham.[2] It received funding as part of Google.org's Renewable Energy cheaper than Coal (RE<C) initiative.[3] "Makani" is Hawaiian for "wind."[4] One of the founders, Corwin Hardham, died in 2012 at age 38.[5] On May 23, 2013, Makani Power was acquired by Google and was folded into Google X.[6]

Working principle

In order to meet its goal of producing low-cost renewable energy, the Makani kite-energy system uses autonomous tethered wings which fly in a circular path and generate electricity via wind turbines mounted upon the main wing, a method already in public domain; expert Miles Loyd in 1980 stated that for large scale purposes flying the generators was expected to be disfavored because of the need to fly the mass of the generators;[7] many of Makani Power competitors have generators kept on the ground, like KiteGen, Italy.[8] The electricity is transmitted to the ground via an electrical cable within the kite's tether.[9] Several patent applications have been made; some have been granted.

Development milestones

In December 2016, Makani operated for the first time a 600 kW prototype with 28 meter wing span.[10][11]
