The global popularity of a shift toward clean-burning and renewable energy sources pendulums regularly depending on political climates, times of war and peace, singular events, and of course, supply and demand.
Kennedy School Fellow Daniele Lantagne is using her engineering background to expand on a program, partially developed by Professor Michael Kremer, to provide clean water to communities in rural areas.
Increased intake of dietary calcium may be key to addressing widespread dental health problems faced by millions of rural residents in Ethiopia's remote, poverty-stricken Main Rift Valley, according to a new Duke University-led study.
Sabesp, the water utility in Sao Paulo, is facing growing pains. Charged with delivering water to one of Brazil’s largest cities, its water system leaks 134 gallons each day from each of its connections.
(Nanowerk News) Nuclear and coal power plants are some of the thirstiest machines on earth. The turbines that spin inside of them to generate electricity require tons and tons of steam, and all of that water has to come from somewhere. Recent studies have estimated that roughly two-fifths of the nation's freshwater withdrawals and three percent of overall freshwater consumption goes to supplying the steam generators at large power stations in the United States. In order to cut down on the enormous quantities of water required to operate these plants, scientists have begun to look for new technologies that could improve their efficiency and reduce the demand for water. As part of a larger consortium involving partners from several energy companies, universities, and government agencies, researchers at the U.S. Department of Energy's Argonne National Laboratory are developing a special class of nanoparticles that partially melt as steam evaporates from a plant's cooling towers, absorbing a significant percentage of the diffused heat in the system.
