US DOE awards ~$5M to expand research on methane hydrates

Green Car Congress

When methane hydrates are “melted,” or exposed to pressure and temperature conditions outside those where the formations are stable, the solid crystalline lattice turns to liquid water, and the enclosed methane molecules are released as gas. Massachusetts Institute of Technology (MIT). MIT will work with the U.S. Earlier post.).

MIT Researchers Elucidate Model for Escape of Underground Methane in Frozen Regions; Current Rate of Escape May be Much Faster Than Earlier Believed

Green Car Congress

Graphic / Ruben Juanes, MIT. Researchers at MIT have elucidated how underground methane in frozen regions—e.g., In the hydrate phase, a methane gas molecule is locked inside a crystalline cage of frozen water molecules. Video / Ruben Juanes and Antone Jain, MIT. Click to enlarge.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V)

Behind the Wheel, Under the Hood of Rivian's R1T

Cars That Think

Scaringe—a bespectacled mechanical engineer with a PhD from MIT—a billionaire by the age of 38. But for proof, the R1T successfully completed the TransAmerica Trail, a roughly 5,000-mile gauntlet from North Carolina to the Oregon coast. Instead, it’s the Rivian R1T, from the California start-up that’s already made founder R.J.

Video Friday: Turkey Sandwich

Cars That Think

Engineers at Georgia Tech are the first to study the mechanics of springtails, which leap in the water to avoid predators. MIT ] The researchers from North Carolina State University have recently developed a fast and efficient soft robotic swimmer that swims resembling human's butterfly-stroke style.
