A new design for nuclear plants built on floating platforms, modeled after those used for offshore oil drilling, could help avoid disasters in the future. Such floating plants would be designed to be automatically cooled by the surrounding seawater in a worst-case scenario, which would indefinitely prevent any melting of fuel rods, or escape of radioactive material.
Engineers have created new ceramic materials that could be used to store hydrogen safely and...
Zero-emission hydrogen fuel cell systems soon could be powering the forklifts used in warehouses...
A project has demonstrated that the superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.
The problem with solar power is that sometimes the sun doesn’t shine. Now, scientists have come up with an ingenious workaround— a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand.
Researchers have developed a glass fabric-based thermoelectric generator that is extremely light and flexible and produces electricity from the heat of the human body.
Porous silicon, manufactured in a bottom up procedure using solar energy, can be used to generate hydrogen from water, according to mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material.
Experiments have explained the behavior of electrons at tiny step edges on titanium oxide surfaces. This is important for solar cell technology and novel, more effective catalysts.
Scientists have created a copper-based catalyst that produces large quantities of ethanol from carbon monoxide gas at room temperature.
On the less glamorous side of space exploration, there’s the more practical problem of waste— in particular, what to do with astronaut urine. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and much-needed drinking water.
Energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This find may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.
Navy researchers have demonstrated novel technologies, developed for the recovery of carbon dioxide and hydrogen from seawater and conversion to a liquid hydrocarbon fuel, by fueling a radio-controlled replica of the historic WWII P-51 Mustang red-tail aircraft.
Scientists have made a surprising discovery about the degradation of solar cells that could help pave the way to creating a longer lifetime for these cells.
In a recent advance in solar energy, researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible.
Researchers have genetically engineered trees that will break down to produce paper and biofuel more easily. This breakthrough will mean using fewer chemicals, less energy and creating fewer environmental pollutants.
Saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy sufficient to run on-chip applications, according to an international team of engineers.
The electrochemical reactions inside the porous electrodes of batteries and fuel cells have been described by theorists, but never measured directly. Now, a team has figured out a way to measure the fundamental charge transfer rate— finding some significant surprises.
Researchers at have improved the performance and capacity of lithium batteries by developing better-performing, cheaper materials for use in anodes and cathodes.
New research has found that the trailblazing “perovskite” material used in solar cells can double up as a laser, strongly suggesting the astonishing efficiency levels already achieved in these cells is only part of the journey.
Research has shown that a carbon coating on electric car batteries not only affects conductivity and performance, but also alters the chemistry of the battery material’s interactive surface.
The first 3-D nanoscale observations of microstructural degradation during charge-discharge cycles could point to new ways to engineer battery electrode materials for better performance.
Researchers have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications.
With biofuels being used globally on a wider scale than ever before, scientists are discussing the implications of their use on human and environmental health.
Researchers have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bacteria for the production of advanced biofuels.
Scientists have developed a next-generation solar cell material that can emit light, in addition to converting light to electricity. The discovery happened almost by chance when a physicist asked his postdoctoral researcher to shine a laser on the hybrid Perovskite solar cell material they were developing.
Researchers have found that, from an energetic perspective, the wind industry can easily afford lots of storage, enough to provide more than three days of uninterrupted power. The solar industry can afford only about 24 hours of energy storage, because it takes more energy to manufacture solar panels than wind turbines.
The Obama administration hopes to fight global warming with the geeky power of numbers, maps and even gaming-type simulations. Officials figure the more you know about climate change the more likely you will do something.
