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. and/or ozone.

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. Slocum and some of his students built a 30-inch-diameter prototype in 2011, which functioned well through charging and discharging cycles, demonstrating the feasibility of the idea.

MIT team testing new SiC nuclear fuel-rod cladding that could lead to safer power plants

Green Car Congress

A team of researchers at MIT is developing and testing a new silicon carbide (SiC) cladding material for nuclear fuel rods that could reduce the risk of hydrogen production by roughly a thousandfold compared to the common zircaloy cladding. SiC is “ very promising, but not at the moment ready for adoption ” by the nuclear industry, he adds.
