As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. This brief study analyzes, for each individual state, the changes from 2018 to 2020 in the use of coal (one of the two most polluting energy sources) to generate electricity. by Michael Sivak, Sivak Applied Research.

Physics Nobel Laureate Herbert Kroemer Dies at 95

Cars That Think

HBTs can handle high-frequency signals (up to several thousand gigahertz) and are commonly used in radio frequency systems, including RF power amplifiers in cell phones. He retired in 2018. Two years later, he received a master’s degree in electrical engineering from the University of Missouri in Rolla.

Brookhaven researchers improve understanding of how plants regulate oil synthesis; potential for more abundant bio-fuels and -products

Green Car Congress

When colleagues at the University of Missouri discovered an inactive version of one of the four enzyme subunits in 2016, Shanklin suspected that this inactive subunit might be the cause of the permanent shutdown—by taking the place of one of the active subunits in the enzyme. 00216.2018; doi: 10.1104/pp.18.00216. 18.00216.

Study finds drone-based delivery could reduce GHG emissions and energy use in the transportation sector, if deployed sensibly

Green Car Congress

The range of regional greenhouse gas (GHG) intensities of electricity in the US is represented by comparing results from low-carbon California to relatively high-carbon Missouri. Additional warehousing requirements for drone and van pathways are included. Drones are favored in regions with relatively clean electricity, such as California.

Hyperloop: An Engineering Marvel or An Elite Day Dream

Get Electric Vehicle

The company claims it will be able to accomplish this by excavating smaller tunnels, developing faster and more efficient digging machinery, and replacing diesel-powered machines with electric ones. Tunnels can cost up to $1 billion per mile to dig; The Boring Company wants to dig tunnels for one-tenth the cost. Virgin Hyperloop One.
