MIT team developing 1MW motor for electric aviation

Green Car Congress

A team of MIT engineers is developing a 1MW motor that could be a key stepping stone toward electrifying larger aircraft. A modular, single-phase winding pattern increases the robustness and power density of the system by enabling single-phase inverter drives. High power density electric machine for turboelectric propulsion.

MIT proof-of-concept demo of ionic wind propulsion for aircraft

Green Car Congress

MIT researchers have demonstrated that an aircraft with a 5-meter wingspan can sustain steady-level flight using ionic-wind propulsion. He expects that in the near-term, such ion wind propulsion systems could be used to fly less noisy drones. The MIT team’s final design resembles a large, lightweight glider.

MIT, NASA engineers develop morphing wing

Green Car Congress

The wing was tested in a NASA wind tunnel. The new wing was designed to be as large as could be accommodated in NASA’s high-speed wind tunnel at Langley Research Center, where it performed even a bit better than predicted. Wing is assembled from hundreds of identical subunits. Image: Kenny Cheung, NASA Ames Research Center.

MIT-Led Team Designs Two Airplanes That Would Use 70% Less Fuel Than Current Models

Green Car Congress

An MIT-led team has designed an airplane that is estimated to use 70% less fuel than current planes while also reducing noise and emission of NO x. Images: MIT/Aurora Flight Sciences. MIT was the only university to lead one of the six US teams that won contracts from NASA in October 2008. Click to enlarge.

MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. The key to this Ocean Renewable Energy Storage (ORES) system is the placement of 30-meter-diameter hollow concrete spheres on the seafloor under the wind turbines. Earlier post.).

Liquid Metal Battery Corp secures patent rights from MIT

Green Car Congress

Liquid Metal Battery Corporation (LMBC), a Cambridge, Massachusetts company founded in 2010 to develop new forms of electric storage batteries that work in large, grid-scale applications, has secured the rights to key patent technology from MIT. Patents for all liquid metal battery inventions were licensed from MIT.
