MIT, Scripps study examines behavior of midwater sediment plumes from deep-sea nodule mining

Green Car Congress

In April, the BMW Group, WWF and other companies—including the Volvo Group—undertook, as a precautionary measure, not to use deep-ocean minerals or finance deep-sea mining until comprehensive scientific research into the impact of deep-sea mining can be conducted and the consequences for the environment are clearly assessed.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% Current airplane design uses engines anchored beneath each wing. increase in block fuel burn. —Prashanth et al.

MIT Sequential Decomposition Synthesis process produces thin solid-state electrolytes without sintering

Green Car Congress

A team from MIT has developed a new approach to fabricating oxide-based solid-state electrolytes that are comparable in thickness to the polymer separators found in current Li-ion batteries without sintering: sequential decomposition synthesis (SDS).

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. The design was one of two that the team, led by faculty from the Department of Aeronautics and Astronautics, presented to NASA last month as part of a $2.1 Click to enlarge.

Algorithm Uses Evolution To Design Robots

Cars That Think

To accomplish tasks, they need both a well-designed body and a “brain,” or controller. But there are few ways to optimize a robot’s design at the same time. Unless the designer is an algorithm. The results are robots that are patchworks of colored squares, moving through video game-like environments.

MIT team finds aviation emissions’ impacts on air quality larger than on climate

Green Car Congress

Researchers at MIT have determined that growth in aviation causes twice as much damage to air quality as to the climate. —lead researcher Dr Sebastian Eastham, from the Laboratory for Aviation and the Environment in MIT's Department of Aeronautics and Astronautics.
