Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

Department of Energy (DOE) released a report suggesting that, in theory, over 300 former and present coal power plants could be converted to nuclear. Most nuclear plants around the world today are large light-water reactors, with capacities well over a gigawatt—quite a bit more than typical coal plants. On 13 September, the U.S.

US DOE Awards $37 Million for Marine and Hydrokinetic Energy Technology Development

Green Car Congress

The 27 projects range from concept studies and component design research to prototype development and in-water device testing. The system will employ tidal turbine blades to pressurize and push the water without using any underwater high-ratio gears or electrical components. DOE Funding: $160,000. Total Project Value: $192,000.

NRC report projects sea level off most of California will rise at slightly higher rate than global average; lower rate for Oregon, Washington, NorCal; variety of factors affect outcome

Green Car Congress

Projected sea-level rise off California, Oregon, and Washington for 2030 (blue), 2050 (green), and 2100 (pink), relative to 2000, as a function of latitude. Sea levels off Washington, Oregon, and northern California will likely rise less, about 60 centimeters over the same period of time.

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

This indicates that we may be greatly underestimating the methane fluxes presently occurring in the ocean and from underground into Earth’s atmosphere. In the hydrate phase, a methane gas molecule is locked inside a crystalline cage of frozen water molecules. The stability of the hydrate stability zone is climate-dependent.

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

Green Car Congress

You need large auxiliary systems to remove the carbon dioxide and water, and it’s very hard to do this.” All active masses of the cathode throughout cycling are solid, which presents not only large energy density but compatibility with the current battery manufacturing infrastructure.
