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. Electric power generation is the greatest contributor to out-of-state pollution-related deaths, the findings suggest.

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. The research was supported by the MIT Arthur Samberg Energy Innovation Fund. —Daniel Cohn.

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% —Steven Barrett, professor of aeronautics and astronautics at MIT and corresponding author. increase in block fuel burn.

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. —Dr Eastham.

MIT-led study suggests mobile-phone data provide a deeper picture of pollution exposure in urban settings

Green Car Congress

A study led by MIT researchers, focused on New York City, suggests that using mobile-phone data to track people’s movement provides an even deeper picture of exposure to pollution in urban settings than by studying air-quality levels in fixed places. —Nyhan et al. But that’s sensitive to where the [measuring] stations are.

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.
