The Department of Energy and IBM are serious about developing lithium air batteries capable of powering a car for 500 miles on a single charge – a five-fold increase over current plug-in batteries that have a range of about 40 to 100 miles, the DOE said.
The agency said 24 million hours of supercomputing time out of a total of 1.6 billion available hours at Argonne and Oak Ridge National Laboratories will be used by IBM and a team of researchers from those labs and Vanderbilt University to design new materials required for a lithium air battery. The calculations will be performed at Oak Ridge and Argonne, which house two of the world’s top ten fastest computers, the group said
The European Union officially communicated its target to cut CO2 emissions by 20 per cent by 2020 compared to 1990 levels, with an option to raise the offer to 30 per cent if other nations make comparable efforts, the European Commission said on Thursday.

The 2010 Environmental Performance Index (EPI) ranks 163 countries on 25 performance indicators tracked across ten policy categories covering both environmental public health and ecosystem vitality. These indicators provide a gauge at a national government scale of how close countries are to established environmental policy goals.
Can ethics be quantified? Or, better yet, can a lack of ethics be quantified?
This week, the Swiss research firm Covalence released its annual ranking of the overall ethical performance of multinational corporations. The idea behind the Covalence research is that there’s value — both for companies and consumers — in measuring corporations against an ethical standard.
