A team of scientists report in a new study that they have found evidence of hardy, methane-producing microbes in a fresh water spring. Previously methane-producing microbes that feed off chemical reactions between water and rock were found in vents deep on the ocean floor. The scientists are now confirming the evidence of this process has […]






MIT’s new approach to the design of a liquid battery uses a passive, gravity-fed arrangement similar to an old-fashioned hourglass. The concept could offer great advantages due to the system’s low cost and the simplicity of its design and operation. The MIT team of researchers has made a demonstration version of the new battery. Liquid […]






Sweden’s KTH The Royal Institute of Technology researchers are using thermoelectric generation to save vehicles hundreds of liters of fuel and reduce their carbon emissions by as much as 1,000 tons per year. Working with automotive manufacturer Scania, the researchers from Sweden’s KTH Royal Institute of Technology have been testing semi trucks equipped with a […]






Chemists from Hiroshima University have developed organic radical batteries that are re-chargeable and continue to function at below-freezing temperatures. The Hiroshima team uses a new synthesis method to make an organic battery. The team has a step into one of the hardest problems of batteries – how to function well when cooled down. Transporting power […]






Australian engineers at the University of New South Wales (UNSW) have edged closer to the theoretical limits of sunlight to electricity conversion by photovoltaic solar cells with a device that sets a new world efficiency record. The new solar cell configuration developed by the engineers has pushed sunlight to electricity conversion efficiency up to 34.5% […]
