Autonomous Boats Seem More Solvable Than Autonomous Cars

Cars That Think

Where autonomous vehicles have had the most success is in environments with a lot of predictability and structure, which is why I really like the idea of autonomous urban boats designed for cities with canals. MIT has been working on these for years , and they're about to introduce them to the canals of Amsterdam as cargo shuttles and taxis.

MIT team calls initial performance results of magnesium-antimony liquid metal battery “promising”

Green Car Congress

Sectioned Mg||Sb liquid metal battery operated at 700 °C showing the three stratified liquid phases upon cooling to room temperature. The observed cause of failure was evaporation of the molten salt electrolyte into the surrounding containment vessel, a mechanism that could be mitigated by alternative cell designs with reduced head space.

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. The membrane-less design enables power densities of 0.795?W?cm 2 at room temperature and atmospheric pressure, with a round-trip voltage efficiency of 92% at 25% of peak power.

3D Printed Solid-State Battery Rivals Lithium-Ion

Cars That Think

Lithium-ion batteries are everywhere: in smartphones, laptops, electric vehicles, and even in your wristwatch. The next frontier, they say, is the solid-state battery — and perhaps 3D-printed ones, at that. "To The company's 3D-printing platform is based on the binder jet printing process developed by MIT.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Early utility companies like Boston Edison and New York Edison organized EV fleets, favoring electric trucks for their comparatively capacious batteries. In the early years of the automobile, battery-powered electric cars were competitive with cars fueled by gasoline and other types of propulsion.
