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 researchers significantly increase lifetimes of solid oxide fuel cells by changing pH

Green Car Congress

MIT researchers have found that changing the pH of the system can increase the lifetimes of a range of technologies including fuel cells. In the electrolysis mode, electricity from, say, the wind, can be used to generate storable fuel such as methane or hydrogen. They can also be made without using costly metals like platinum.

MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. —study leader Steven Barrett, an associate professor of aeronautics and astronautics at MIT.

Scientists have increased the life of fuel cells – why that matters for solar and wind

Electrek

In research that could jumpstart work on a range of technologies including fuel cells – key to storing solar and wind energy – MIT researchers have found a relatively simple way to increase the lifetimes of these devices: changing the “pH” of the system.

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.).

MIT autonomous boats can target and latch onto each other: dynamic roboat structures

Green Car Congress

To further that vision, MIT researchers have given new capabilities to their fleet of robotic boats—which are being developed as part of an ongoing project—that lets them target and clasp onto each other, and keep trying if they fail. Moreover, the roboat notices if it has missed the connection, backs up, and tries again.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez.
