Although low temperature fuel cells powered by methanol or hydrogen have been well studied, existing low temperature fuel cell technologies cannot directly use biomass as a fuel because of the lack of an effective catalyst system for polymeric materials.
Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide (CO2) underground – and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches.
He found that by adding organic layers between layers of zinc it is possible to improve the performance of thermoelectric materials. The organic layers are also believed to have a major effect in reducing thermal conductivity, which would be very useful in thermoelectric materials.
Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges. These are just two of the possibilities raised by a novel supercapacitor design invented by material scientists at Vanderbilt University that is described in a paper published in the Oct. 22 issue of the journal Scientific Reports.
A lot of energy is wasted when machines turn hot, unnecessarily heating up their environment. Some of this thermal energy could be harvested using thermoelectric materials; they create electric current when they are used to bridge hot and cold objects.
The quest to harness hydrogen as the clean-burning fuel of the future demands the perfect catalysts—nanoscale machines that enhance chemical reactions. Scientists must tweak atomic structures to achieve an optimum balance of reactivity, durability, and industrial-scale synthesis. In an emerging catalysis frontier, scientists also seek nanoparticles tolerant to carbon monoxide, a poisoning impurity in hydrogen derived from natural gas. This impure fuel—40 percent less expensive than the pure hydrogen produced from water—remains largely untapped.
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon.
Waves may not be that predictable, even though technology and forecasting has improved (from World War II, when wave forecasting began in earnest, thanks to the requirements of the D-Day landing, up through the sophisticated models used by sports organizations like Surfline today), but the tides are thoroughly predictable.
Embryonic sharks, still within the egg, can sense danger and freeze toavoid being detected by predators, say marine scientists at the University of Western Australia.
Recent statistics suggest Americans waste up to 40 percent of the food that passes through our kitchens.
By now you've probably seen the teaser commercials for Revolution, the new show by JJ Abrams that's slated to debut on September 17.
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have successfully demonstrated a method of converting carbon dioxide into liquid fuel isobutanol using electricity.
What would happen if you jumped into a lake and then, still wet, went swimming in the ocean?
Dead cellphones could soon be a thing of the past, thanks to a new technology that can harvest enough juice for another call from the user's own body heat.
A team from the University of Tennessee, Knoxville, claims to have developed a low-cost method of power generation based on photosynthetic processes.
Americans own an estimated 250 million vehicles, and drive approximately six billion miles every day.
But what if we were able to harness the energy used in transporting goods and people to generate electricity with no additional emissions?
The key to saving vast amounts of energy? It's right there on your kitchen counter, say scientists at Oregon State University.
Researchers at Michigan State University have developed a new strain of a microbe which can efficiently clean up nuclear waste and other toxic metals while generating electricity.
According to the Department of Energy and Climate Change, households in the United Kingdom use the equivalent of 7.6 million tons of oil per year to heat water.
University of Minnesota engineers say they've discovered a completely new way of generating electricity.
