Long-lasting, water-based nuclear battery developed

By - September 17, 2014 1 Picture
Researchers working at the University of Missouri (MU) claim to have produced a prototype of a nuclear-powered, water-based battery that is said to be both longer lasting and more efficient than current battery technologies and may eventually be used as a dependable power supply in vehicles, spacecraft, and other applications where longevity, reliability, and efficiency are paramount.

Buddhist singing bowls could inspire highly efficient solar cells

By - September 14, 2014 1 Picture
While the unique shape of Buddhist singing bowls is vital to the creation of their signature sound, a researcher from Australia National University (ANU) has used their design as the inspiration for a new breed of solar cells. In completing his PhD at the University of Cambridge, Dr Niraj Lal found that just as the bowls cause sound to resonate, miniaturized versions can be made to interact with light in much the same way, inspiring solar cells better able to capture sunlight.

MIT researchers propose recycling lead from old batteries to produce new solar cells

By - August 18, 2014 1 Picture
The world of modern technology is one of out with the old, in with the new. For battery technology, that means the expected demise of lead-acid batteries and replacement by a more efficient, cheaper, and environmentally-friendly alternative. This is good news, but leaves the problem of what to do with all the lead in the batteries currently in use when the time comes to dispose of them? Researchers at MIT have an answer – use it to make solar cells. Read More

NASA selects proposals for advanced energy storage technologies

By - August 9, 2014 2 Pictures
Once upon a time, energy systems for space missions were simple. You used batteries for very short missions, solar panels in the inner Solar System, nuclear power generators if you were beyond Mars or needed a lot of power, and fuel cells for manned spacecraft. However, as space exploration starts looking into lunar polar craters, comets, and the icy moons of Jupiter, new energy systems will be needed. To anticipate that need, NASA has made awards to four proposals to develop advanced energy storage technology for future manned and unmanned space missions.. Read More

Cigarette butts transformed into high-performance supercapacitor component

By - August 6, 2014 1 Picture
Billions of cigarette butts are discarded around the world each year and, even when disposed of properly, pose a threat to the environment by leaching arsenic, lead and other nasty chemicals into land and waterways. New research shows these butts could be set for a new lease on life, with a team of Korean scientists demonstrating that used cigarette filters could actually double as a highly-effective energy storage material.

All-in-one system uses plant oils to power, heat, and cool the home

By - August 4, 2014 1 Picture
A team of researchers led by Newcastle University has produced an all-in-one Biofuel Micro Trigeneration (BMT) prototype system fueled entirely by unprocessed plant oils that provides combined cooling, heating, and electrical power. This first-generation system is designed for use in homes, with the potential for up-scaling for larger commercial and industrial applications. Read More

Sponge-like structure generates steam using lowest concentration of solar energy yet

By - July 22, 2014 2 Pictures
Researchers working at MIT’s Department of Mechanical Engineering claim to have produced a sponge-like substance that helps convert water to steam using sunlight one-hundredth as bright as that required by conventional steam-producing solar generators. A composite of graphite flakes layered on a bed of carbon foam, the new material is reported to convert as much as 85 percent of received solar energy into steam. Read More
