MIT team outlines path to low-cost solar-to-fuels devices; the artificial leaf

Green Car Congress

A team of researchers at MIT has described a framework for efficiently coupling the power output of a series-connected string of single-band-gap solar cells to an electrochemical process that produces storable fuels. This paper performs an equivalent circuit analysis for multiple series-connected devices. Source: Winkler 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.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. aligned with the low-cost systems engineering and.

MIT team develops sub-terahertz-radiation receiving system to help steer driverless cars through fog and dust

Green Car Congress

MIT researchers have now developed a sub-terahertz-radiation receiving system that could help steer driverless cars when traditional methods fail. Our low-cost, on-chip sub-terahertz sensors will play a complementary role to LiDAR for when the environment is rough.

Independent testing shows 21.2% reduction in fuel consumption with XL Hybrids retrofit system

Green Car Congress

XL Hybrids’ hybrid electric powertrain is a low-cost, low-risk, bolt-on, post-transmission parallel hybrid technology designed for Class 1–3 commercial vehicles that integrates seamlessly with the conventional internal combustion engine and transmission. Our hybrid controller connects to the CAN; our controller is read-only.

MIT’s fleet of autonomous boats can now shapeshift

Green Car Congress

The autonomous boats—rectangular hulls equipped with sensors, thrusters, microcontrollers, GPS modules, cameras, and other hardware—are being developed as part of the ongoing “ Roboat ” project between MIT and the Amsterdam Institute for Advanced Metropolitan Solutions (AMS Institute). Collision-free trajectories.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

The aerobic microbe has been engineered at MIT and is capable of converting a variety of organic compounds into oil, from which biodiesel may be produced. The process will produce butanol and will also be able to produce ethanol The research team has a strong connection with Microbial Fuel Cell Technologies, LLC in this area of research.
