A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable.
Scientists today unveiled new technology intended to move soybeans, second only to corn as the top food crop in the U.S., along that same use-to-all path as a raw material for a wider portfolio of products.
With enough sunlight falling on home roofs to supply at least half of America's electricity, scientists have described advances toward the less-expensive solar energy technology needed to roof many of those homes with shingles that generate electricity.
A computer model that can identify the best molecular candidates for removing carbon dioxide, molecular nitrogen and other greenhouse gases from power plant flues has been developed by researchers with the U.S. Department of Energy (DOE)ís Lawrence Berkeley National Laboratory (Berkeley Lab), the University of California (UC) Berkeley and the University of Minnesota. The model is the first computational method to provide accurate simulations of the interactions between flue gases and a special variety of the gas-capturing molecular systems known as metal-organic frameworks (MOFs).
An economically feasible way to store solar energy in existing residential power networks is the subject of an award winning paper written by two Virginia Tech electrical engineers and presented at an international conference.
Life evolved in a toxic world long before humans began polluting it, according to a University of Massachusetts environmental toxicologist, who added that understanding life's evolutionary response to environmental poisons can help people to fight destructive effects.
A new discovery should make the alternative fuel butanol more attractive to the biofuel industry. University of Illinois scientist Hao Feng has found a way around the bottleneck that has frustrated producers in the past and could significantly reduce the cost of the energy involved in making it as well.
Engineers at Oregon State University have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity.
