Engineers at the University of Bath have shown that it’s possible to capture and use energy created by the natural reactions occurring in microorganisms within soil.
A team of chemical and electrical engineers has demonstrated the potential of cheap, simple “soil microbial fuel cells” (SMFCs), buried in the earth to power an electrochemical … [more…]

Mixing drinking water with chlorine, the United States’ most common method of disinfecting drinking water, creates previously unidentified toxic byproducts, says Carsten Prasse from Johns Hopkins University and his collaborators from the University of California, Berkeley and Switzerland.
The researchers’ findings were published … [more…]
