Cleaning water while generating energy
A fuel cell system that can generate electricity from organic compounds and clean up wastewater at the same time has been developed by scientists in China; the cell uses light energy to degrade organic compounds in wastewater, generating electrons that pass through to the cathode, which converts the chemical energy into electrical energy

Researchers develop controversial earthquake detection network
Researchers at a Silicon Valley company are hard at work developing an experimental network of electromagnetic sensors that could predict large earthquakes as much as two weeks in advance; the theory behind the research is disputed, but Tom Bleier, the inventor and chief engineer behind project QuakeFinder, hopes to prove seismologists wrong

Radiation fears cripple Japanese food exports
Japanese agricultural exports have yet to recover from the 11 March earthquake and tsunami due largely to fears of radioactive contamination; to combat these fears, local governments have done all they can to assure consumers that their products are safe; consumers remain wary despite these reassurances, and as a result the Japanese agricultural sector is struggling

Storing CO2 underground to extract electricity
A team of scientists, led by the Berkeley Lab, hopes to become the first in the world to produce electricity from the Earth’s heat using CO2; They also want permanently to store some of the CO2 underground, where it can not contribute to climate change

Towing icebergs to provide fresh water for parched regions
A third of the world’s population — more than two billion people — lives without access to clean drinking water, and studies show that the situation will only get worse; a French innovator has an idea: towing icebergs from the Greenland and Antarctica to regions most in need of fresh water; a computer simulation shows this solution to be viable and affordable
