MIT study finds Uber & Lyft increase congestion, decrease transit ridership and don’t affect vehicle ownership

Green Car Congress

Researchers at MIT report that the entrance of transportation network companies (TNCs)—specifically Uber and Lyft, which together have a 98% share of the market—in cities led to increased road congestion in terms of both intensity (by 0.9%) and duration (by 4.5%); an 8.9% —Diao et al.

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.

MIT team discovers two mechanisms at work in Li dendrite formation

Green Car Congress

Researchers at MIT have carried out the most detailed analysis yet of lithium dendrite formation from lithium anodes in batteries and have found that there are two entirely different mechanisms at work. The MIT team carried out tests at higher current levels that clearly revealed the two distinct types of growth. Brushett and Martin Z.

MIT analysis finds current EVs could replace ~90% of personal vehicles now on the road based on driver’s energy consumption

Green Car Congress

A study by a team at MIT has concluded that roughly 90% of the personal vehicles on the road in the US could be replaced by an electric vehicle available on the market today, even if the cars can only charge overnight.
