An MIT team has identified a process that could be used to harness methane that is now wasted by being burned off at wellheads.
Researchers at Binghamton University, State University of New York have created a micro-scale biological solar cell that generates a higher power density for longer than any existing cell of its kind.
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research at Los Alamos National Laboratory's Nanotech Team, the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.
Wind turbines suspended high in the sky have potential as an alternative power source for Saudi Arabia.
TU Graz researchers observe enzymes breaking down cellulose to aid the production of biofuels. The results are now published in Nature Communications.
MIT researchers have developed an 'air-breathing' battery that could store electricity for very long durations for about one-fifth the cost of current technologies, with minimal location restraints and zero emissions. The battery could be used to make sporadic renewable power a more reliable source of electricity for the grid.
MIT researchers have found that supplies of raw materials are unlikely to limit increased production of lithium-ion batteries, although they could pose temporary bottlenecks.
With the sharp and largely unexpected increase in the long-distance movement of domestically produced crude oil, ethanol, and natural gas since 2005, a number of concerns have arisen about the safe transport of these hazardous materials, particularly in relation to railroad track defects, rural communities' emergency response preparedness, and the older tank car designs that will continue to be used in multi-car unit trains, says a new report from the National Academies of Sciences, Engineering, and Medicine.
We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of Penn State engineers have a different type of lithium sulfur battery that could be more efficient, less expensive and safer.
Lithium ion batteries are flammable and the price of the raw material is rising. Are there alternatives? Yes: Empa and ETH Zürich researchers have discovered promising approaches as to how we might produce batteries out waste graphite and scrap metal.
