UC Merced Professor Roland Winston and his team of student researchers have designed and developed a system that gathers and concentrates sunlight onto specially made collector tubes. The heat generated can then be transformed using existing technology for cooling, heating and other potential uses.
Iowa State researchers have developed technologies to efficiently produce, recover and separate sugars from the fast pyrolysis of biomass. That's a big deal because those sugars can be further processed into biofuels.
More than 10 years after electricity deregulation, the nuclear power industry has decreased greenhouse gas emissions by nearly 40 million metric tons of carbon dioxide and saved $2.5 billion a year as a result of operating more efficiently over the past decade, according to a new study.
A new "subconscious mode" for smartphones and other WiFi-enabled mobile devices could extend battery life by as much as 54 percent for users on the busiest networks.
Scientists at Rensselaer Polytechnic Institute are working to optimize a promising new nanomaterial called nanoblades for use in hydrogen storage. During their testing of the new material, they have discovered that it can store and release hydrogen extremely fast and at low temperatures compared to similar materials. Another important aspect of the new material is that it is also rechargeable. These attributes could make it ideal for use in onboard hydrogen storage for next-generation hydrogen or fuel cell vehicles.
Virginia Tech and U.S. Department of Agriculture researchers have shown that transgenic yeast used during fermentation of barley will help modify mycotoxin in the animal feed that is a byproduct of ethanol production.
Batteries could get a boost from a discovery that increases power, energy density and safety while dramatically reducing charge time.
By looking to Mother Nature for solutions, researchers have identified a promising new binder material for lithium-ion battery electrodes that could not only boost energy storage, but also eliminate the use of toxic compounds now used in manufacturing the components.
Although the burning of natural gas emits far less carbon dioxide than coal, a new study by an NCAR researcher concludes that a greater reliance on natural gas would fail to significantly slow down climate change. Coal releases more carbon dioxide, but it also releases particles that cool the planet.
A new study of dust-like particles of soot in the air -- now emerging as the second most important -- but previously overlooked -- factor in global warming provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported here today.
Scientists from the University of Kentucky and the University of Louisville have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight.
Panda poop contains bacteria with potent effects in breaking down plant material in the way needed to tap biomass as a major new source of "biofuels" produced not from corn and other food sources, but from grass, wood chips and crop wastes, scientists reported today at the 242nd National Meeting & Exposition of the American Chemical Society (ACS).
The first nuclear power plant being considered for production of electricity for manned or unmanned bases on the Moon, Mars and other planets may really look like it came from outer space.
Dow Kokam and the Department of Energy's Oak Ridge National Laboratory are working together to enhance the Michigan-based company's capabilities to develop and commercialize advanced lithium ion batteries.
A novel microscopy method is helping scientists probe the reactions that limit widespread deployment of fuel cell technologies.
Algae-based fuel is one of many options among the array of possible future energy sources. New University of Virginia research shows that while algae-based transportation fuels produce high energy output with minimal land use, their production could come with significant environmental burdens.
Researchers in the Pacific Northwest have developed a new catalyst material that could replace chemicals currently derived from petroleum and be the basis for more environmentally friendly products including octane-boosting gas and fuel additives, bio-based rubber for tires and a safer solvent for the chemicals industry.
Data from NASA's Terra satellite shows that when the climate warms, Earth's atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to "believe."
For thousands of years, bakers and brewers have relied on yeast to convert sugar into alcohol and carbon dioxide. Yet, University of Wisconsin-Madison researchers eager to harness this talent for brewing biofuels have found when it comes to churning through sugars, these budding microbes can be picky eaters.
Farmers and other astute observers of nature have long known that crops like corn and sorghum grow taller at night. But the biochemical mechanisms that control this nightly stem elongation, common to most plants, have been something of a mystery to biologists--until now.
1) Nanoscale robots that can flow through blood may yet be a possibility. 2) Making Industry Part of the Climate Solution. 3) New band magnetism. 4) Clean energy production. 5) Thermochemical degradation of plant materials.
Researchers have discovered a way to capture energy transmitted by such sources as radio and television transmitters and cell phone networks. By scavenging this ambient energy from the air around us, the technique could provide a new way to power networks of wireless sensors or other devices.
University at Buffalo chemists have used synchrotron light sources to observe the electron clouds on the surface of graphene, producing a series of images that reveal how folds and ripples in the remarkable material can harm its conductivity.
A new model of the single-celled marine cyanobacterium Cyanothece could help researchers use blue-green algae to make renewable energy by predicting which of its genes are central to capturing energy from sunlight.
How does the power output from solar panels fluctuate when the clouds roll in? And can researchers predict these fluctuations? UC San Diego Professor Jan Kleissl and Matthew Lave, a Ph.D. student in the Department of Mechanical and Aerospace Engineering at the Jacobs School, have found the answer to these questions. They also have developed a software program that allows power grid managers to easily predict fluctuations in the solar grid caused by changes in the cloud cover. The program uses a solar variability law Lave discovered.
