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. —Steven Barrett. The MIT team’s final design resembles a large, lightweight glider.

Porsche presents Mission R concept electric competition car

Green Car Congress

While in conventional electrical machines the cooling fluid flows through a jacket outside the stator, in the case of direct cooling, the oil flows directly along the copper windings. As with the Taycan's electric motors, the hairpin winding contributes to a high yield of power and torque while maintaining compact dimensions.

GM and ABB to Develop Projects for Re-Use of Volt Battery Packs

Green Car Congress

The two companies are collaborating to determine how the Volt’s 16-kWh lithium-ion batteries can be used to provide stationary electric grid storage systems once the batteries have fulfilled their usefulness in customers’ vehicles. The Volt’s battery will have significant capacity to store electrical energy, even after its automotive life.

CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Among the findings of the study, published as an open-access paper in the journal Environmental Research Letters , was that battery electric vehicles with large battery capacity can produce two to three times as much air emissions damage as gasoline hybrid electric vehicles, depending on charge timing.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. High Wind Future: In this scenario, they modified the future case to add wind plants sufficient to produce 20% of generation.
