Researchers at the University of Alicante have patented a new device that allows more efficiently to cultivate microalgae and can be used as raw material for biofuel or for other valuable substances in the agri-food or pharmaceutical industry.
Pakistan is one of the countries most vulnerable to climate change - risks range from the disastrous 2010 floodings that acted as a wake-up call to retreating glaciers impacting freshwater supply. To confront this challenge, the new Centre for Climate Research and Development (CCRD) took up its work this month - a substantial effort to build up indigenous scientific capacities in a place where substantial climate change impacts are actually happening.
The vision of a society in which each inhabitant of the earth manages to consume only 2000 watts has already been around for 15 years. During this time, there has been a steady increase in environmental awareness in the West. Technology has become more efficient and there appears to be very little standing in the way of a sustainable lifestyle. However, as a study by Empa and the Federal Institute of Technology (ETH) Zurich now shows, Mr and Mrs Swiss are still a long way from achieving this.
Bacteria can move electrons at least half a millimeter across a scaffolding made by themselves, of themselves, even under starving conditions. This new finding challenges conventional wisdom, which held that electrical resistance within bacterial biofilms - robust structures held together by a strong matrix - would restrict long-range electron transfer.
Researchers working to improve durability in fuel cell powered buses have discovered links between electrode degradation processes and bus membrane durability. The team is quantifying the effects of electrode degradation stressors in the operating cycle of the bus on the membrane lifetime.
The discovery of potential environmental and human health effects from disposal of millions of rechargeable lithium-ion batteries each year has led scientists to recommend stronger government policies to encourage recovery, recycling and reuse of lithium-ion (Li-ion) battery materials.
Ninety-seven teams from 28 Colorado schools participated in today's car competitions hosted by the US Department of Energy's National Renewable Energy Laboratory. The student teams raced solar and lithium ion powered vehicles they designed and built themselves.
A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year in the United States, one-twelfth of the country's yearly needs.
A cutting edge system is being developed to deploy more solar-based energy plants, enabling the delivery of cleaner power more efficiently, while keeping Europe at the leading edge of energy technologies.
