Exporting US coal to Asia could drop emissions 21 percent
Under the right scenario, exporting U.S. coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning the fossil fuel at plants in the United States, according to a new ...
A bump circuit with flexible tuning ability that uses 500 times less power
A bump circuit with flexible tuning ability that uses 500 times less power and is smaller than previous circuits has been demonstrated by researchers at the University of Tennessee in the US.
Biological effects of Fukushima radiation on plants, insects, and animals
Following the 1986 Chernobyl nuclear power plant meltdown, biological samples were obtained only after extensive delays, limiting the information that could be gained about the impacts of that historic disaster. ...
Satellite system makes eagle spotting a doddle in Scotland
Monitoring natural resources, biodiversity and wildlife data is crucial for economic and ecological sustainability. But in areas that are hard to reach, monitoring becomes a problem. In Scotland, for example ...
Gasification of oil palm biomass to produce clean producer gas for heat, power generation
