Makani *

Makani was an Alphabet (Google X) moonshot developing airborne wind energy — "energy kites" that flew in crosswind loops to generate electricity and sent power to the grid down a tether. Backed within Alphabet and partnered with Shell, Makani wound down in 2020 after roughly 13 years of development. On closure the team open-sourced its full flight-simulation, autopilot controller, visualization, and avionics software stack under Apache-2.0 and published the Energy Kite Collection of technical reports, designs, and flight logs. Makani has no commercial or developer API surface; this API Evangelist profile tracks the company for network completeness.

Makani * is profiled on the APIs.io network. Tagged areas include Company, Frontier Tech, Renewable Energy, Wind Energy, and Airborne Wind.

Makani *’s developer surface includes documentation and 9 more developer resources.
