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.
Scientists have produced the largest flexible, plastic solar cells in Australia - 10 times the size of what they were previously able to - thanks to a new solar cell printer that has been installed at CSIRO.
The production of biofuels from lignocellulosic biomass would benefit on several levels if carried out at temperatures between 65 and 70 degrees Celsius. Researchers with the Energy Biosciences Institute (EBI) have employed a promising technique for improving the ability of enzymes that break cellulose down into fermentable sugars to operate in this temperature range.
NASA's remotely piloted X-48C hybrid-wing-body subscale aircraft, which demonstrates technology concepts for cleaner and quieter commercial air travel, completed an eight-month flight research campaign on April 9.
