Ice slide, avalanche risk from flat areas, due to lubrication of ice from rain or glacial melt, with increasing precipitation in recent years

Climate change could be to blame for one of the world’s largest document ice avalanches, which is flummoxing researchers. Around 100 million cubic meters of ice and rocks gushed down a narrow valley in Tibet on 17 July, killing nine herders and hundreds of sheep and yaks. The avalanche was unusual because it started from a flat point, rather than …

Blade coat, thin film solar strategy pays off for NIST team

Cross-posted from Clean Technica, by Tina Casey  A research team based at the National Institute of Standards and Technology has determined that an economical process for cranking out thin film solar cells can get this close to hitting the “sweet spot” of 10% conversion efficiency. The process yields thin film solar cells that clock in at just over 9.5% and …

Visualization of self-driving carpool fleet by fullness of car, Lisbon, Portugal

A fascinating new simulation finds that self-driving cars will re-form cities: 90% of cars will be eliminated, acres of land will open up, and commute times will drop 10%. A team of transportation scientists at the Organization for Cooperation and Development took data on actual trips in Lisbon, Portugal and looked at how a fleet of self-driving, shared “taxibots” would …

Coal causing 366,000 deaths a year and transportation 137,000 deaths per year from air pollution in China

An August 2016 report by the Health Effects Institute provides the first comprehensive assessment of the current and predicted burdens of disease attributable to coal-burning and other major sources of air pollution in China at the national and provincial levels.  Top findings: Coal-burning was the most important contributor to ambient PM2.5, responsible for 40% of population-weighted PM2.5 in China. Given the large …
