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

Green Car Congress

Now, oceanographers at MIT, the Scripps Institution of Oceanography, and elsewhere have carried out an experiment at sea for the first time to study the turbulent sediment plume that mining vessels would potentially release back into the ocean. Earlier post.). To pin down these dynamics, the team went to sea. n Bancaria “la Caixa.”.

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 engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains. Dubbs Professor of Chemical Engineering at MIT and the senior author of the new study. —Michael Strano.

MIT study finds materials risk exposure increases significantly with vehicle electrification

Green Car Congress

Now, a study by a team from MIT’s Materials Systems Laboratory, with support from Ford, provides insight into how electrification is changing vehicle composition and how that change is driving supply risk vulnerability. Modern automobiles are built with more than 2,000 different compounds comprising 76 different elements.

MIT study finds stiffer roadways could improve truck fuel efficiency

Green Car Congress

Now, a study by MIT researchers suggests that small changes in roadway paving practices could reduce that efficiency loss, at little to no cost. The study examined state-by-state data on climate conditions, road lengths, materials properties, and road usage, and modeled different scenarios for pavement resurfacing practices.

MIT study finds computational load for widespread autonomous driving could be a huge driver of global carbon emissions

Green Car Congress

Realizing that less attention has been paid to the potential footprint of autonomous vehicles, the MIT researchers built a statistical model to study the problem. This research was funded, in part, by the National Science Foundation and the MIT-Accenture Fellowship. Sudhakar, Soumya, Vivienne Sze, and Sertac Karaman.

MIT study finds workplace charging and delayed home charging can mitigate electricity demand and cost

Green Car Congress

A new study by MIT researchers examines these risks and how they amplify or mitigate each other. Large-scale deployment of battery electric vehicle (BEV) and photovoltaic (PV) electricity technologies could raise electricity costs by increasing peak evening electricity demand and causing overgeneration of electricity during midday.
