alternative energy

New MIT research points the way to a technology that might make it possible to harvest much of the wasted heat produced by everything from computer processor chips to car engines to electric powerplants, and turn it into usable electricity.
More than half of the energy consumed worldwide is wasted, most of it in the form [...]

In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-energy process that outweighs the benefits of not using petroleum to power vehicles.
New findings from a team of researchers from the University of [...]

An adhesive used in products like laminate countertops may also help cement a place for economically viable biofuels, according to a Kansas State University researcher.
Susan Sun directs K-State’s Bio Materials and Technology Laboratory, where she studies bio-based materials. Her research group is studying adhesives made from by-products of soybean, corn, sorghum and biomass fuels.

A new report from the National Research Council examines and, when possible, estimates “hidden” costs of energy production and use — such as the damage air pollution imposes on human health — that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. The report [...]

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To [...]

A new ceramic material described in this week’s issue of the journal Science could help expand the applications for solid oxide fuel cells — devices that generate electricity directly from a wide range of liquid or gaseous fuels without the need to separate hydrogen.
Though the long-term durability of the new mixed ion conductor material must [...]

The largest U.S subsidies to fossil fuels are attributed to tax breaks that aid foreign oil production, according to research to be released on Friday by the Environmental Law Institute (ELI) in partnership with the Woodrow Wilson International Center for Scholars. The study, which reviewed fossil fuel and energy subsidies for Fiscal Years 2002-2008, reveals [...]

Chemical engineers at Oregon State University have invented a new technology to deposit “nanostructure films” on various surfaces, which may first find use as coatings for eyeglasses that cost less and work better.
Ultimately, the technique may provide a way to make solar cells more efficiently produce energy.
The films reduce the reflectance of light, and in [...]

A team of environmental scientists from Harvard and Tsinghua University demonstrated the enormous potential for wind-generated electricity in China. Using extensive metrological data and incorporating the Chinese government’s energy bidding and financial restrictions for delivering wind power, the researchers estimate that wind alone has the potential to meet the country’s electricity demands projected for 2030.

Watermelon juice can be a valuable source of biofuel. Researchers writing in BioMed Central’s open access journal Biotechnology for Biofuels have shown that the juice of reject watermelons can be efficiently fermented into ethanol.
Wayne Fish worked with a team of researchers at the USDA - Agricultural Research Service’s South Central Agricultural Research Laboratory in Lane, [...]

Expansion of renewable energies should appreciably improve the health status of the 700,000 US workers employed in the energy sector, according to a commentary by Medical College of Wisconsin researchers, in Milwaukee. Their review is published in the August 19, 2009, issue of JAMA, the Journal of the American Medical Association.
Steven Sumner, M.D., who completed [...]

The American Chemical Society’s (ACS) 238th National Meeting will be the site of a rare “thought experiment” intended to focus the creative genius of hundreds of scientists on solutions to one of the 21st Century’s most daunting problems: Finding sustainable new sources of energy. The exercise will use a computer game format in the Walter [...]

To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such catalyst. The results [...]

At a time when water supplies are scarce in many areas of the United States, scientists in Minnesota are reporting that production of bioethanol — often regarded as the clean-burning energy source of the future — may consume up to three times more water than previously thought. Their study appeared in ACS’ journal Environmental Science [...]

Researchers the world over are striving to develop organic solar cells that can be produced easily and inexpensively as thin films that could be widely used to generate electricity.
But a major obstacle is coaxing these carbon-based materials to reliably form the proper structure at the nanoscale (tinier than 2-millionths of an inch) to be highly [...]

Call it a “shrimp cocktail” for your fuel tank. Scientists in China are reporting development of a catalyst made from shrimp shells that could transform production of biodiesel fuel into a faster, less expensive, and more environmentally friendly process. Their study is scheduled for the Aug. 20 issue of ACS’ Energy & Fuels, a bi-monthly [...]

Concerns about dwindling fossil fuel resources, current levels of petroleum consumption, and growing pressure to shift to more sustainable energy sources are among the many factors prompting the transition from our current energy infrastructure to one that uses less carbon and requires the efficient conversion of energy. This necessitates collecting energy from ambient sources including [...]

Scientists in Nevada are reporting development of a new and environmentally friendly process for producing biodiesel fuel from “chicken feather meal,” made from the 11 billion pounds of poultry industry waste that accumulate annually in the United States alone. Their study is scheduled for the July 22 issue of ACS’ Journal of Agricultural and Food [...]

The stress of rising natural gas prices is leading many consumers to rethink how they heat their homes. For some this means moving towards modern alternative energy options, while others have been turning to a more traditional method for a solution to these rising costs. In Canada and the United States, wood burning stoves have [...]

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have demonstrated a way to fabricate efficient solar cells from low-cost and flexible materials. The new design grows optically active semiconductors in arrays of nanoscale pillars, each a single crystal, with dimensions measured in billionths of a [...]
