Researchers use IPCC AR5 models to forecast 10% drop in Colorado River flow in next few decades

Green Car Congress

It may not sound like a phenomenally large amount except the water and the river is already over-allocated. The present study narrows in on three key regions for water managers—the Colorado River headwaters; the greater California-Nevada region; and Texas, which gets nearly all of its water from within state borders.

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

The microbes and minerals in soil systems regulate water, cycle nutrients, filter pollutants, physically support plants, and sequester greenhouse gasses. Climate change also causes indirect effects on health, such as food and water insecurity, the spread of climate-sensitive infectious diseases, and population displacement.

NREL researchers report on two approaches to upgrading biomass pyrolysis oil for hydrocarbon fuels

Green Car Congress

At last month’s World Renewable Energy Forum 2012 in Denver, Colorado, researchers from the US National Renewable Energy Laboratory presented papers on two different approaches to upgrade pyrolysis oils to hydrocarbon fuels or fuel intermediates. Fast pyrolysis can convert about 70% of the mass and energy into the liquid product.

AI-Guided Robots Are Ready to Sort Your Recyclables

Cars That Think

That’s a lot of material made from finite resources that needlessly goes to waste. In the future, AI systems could also sort by combinations of material and by original use, enabling food-grade materials to be separated from containers that held household cleaners, and paper contaminated with food waste to be separated from clean paper.

Robert Kahn: The Great Interconnector

Cars That Think

Bob Taylor, then at the Advanced Research Projects Agency (ARPA) , got interested in connecting computers, in part to save the organization money by getting the expensive computers it funded at universities and research organizations to share their resources over a packet-switched network. But I had come from the conceptual side of the world.
