MIT researchers developing LiDAR on a chip

Green Car Congress

This mechanical apparatus limits the scan rate of the LiDAR system while increasing both size and complexity, leading to concerns about long-term reliability, especially in harsh environments. Silicon’s index of refraction—which changes the speed and phase of light passing through it—depends on its temperature.

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.

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

New ultrafast camera for self-driving vehicles and drones

Green Car Congress

Unlike typical optical cameras, which can be blinded by bright light and unable to make out details in the dark, NTU’s new smart camera can record the slightest movements and objects in real time. Each pixel in the sensor can individually monitor the slope of change in light intensity and report an event if a threshold is reached.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

” The MIT report said that natural gas should be seen as a “ bridge ” to a low-carbon regime, rather than as the ultimate long-term solution itself. MIT: The Future of Natural Gas. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Source: IEA.

Video Friday: Lunar Rover

Cars That Think

In December of 2021 at the mock lunar surface environment in JAXA’s Sagamihara Campus, the GITAI lunar robotic rover R1 conducted numerous tasks and mobility operations, successfully completing all planned tests. This is cool looking, but I'd need to know more about how this system can deal with an actual lunar environment, right?
