Concentrating solar-thermal power technologies can help eliminate carbon dioxide emissions from the energy sector. UC Davis and eight partnering institutions were selected to receive $4.6 M from the Department of Energy to advance high temperature receiver development for industrial process heat and solar thermal power generation. The team, led by Vinod Narayanan and Erfan Rasouli at UC Davis, will design, develop, and de-risk a 150-kilowatt solar-thermal receiver able to heat supercritcal carbon dioxide or air to temperatures from 600-900°C.
A small Nevada wildflower named Tiehm’s buckwheat might still be living in obscurity if it had not happened to grow in soil full of lithium. As it is, that could prove its downfall.
Lithium is needed to make the high-powered batteries that are helping the world transition to electric vehicles. Demand is soaring, and mining companies are eager to take it out of the ground at several new sites in Nevada, already home to the only existing lithium mine in the U.S.
“One guy on a bulldozer could drive it extinct in one afternoon,” says Patrick Donnelly, the Great Basin Director for the Center for Biological Diversity and one of the flower’s biggest advocates.
He and some other conservationists see the flower and the mine as emblematic of a broad and disturbing trend: There is a growing conflict, they say, between efforts to address two environmental crises—a rapidly warming climate on the one hand, and a staggering rise in extinction on the other.
