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

By - August 18, 2014
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

Cigarette butts transformed into high-performance supercapacitor component

By - August 6, 2014
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
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

Sainsbury’s supermarket to be powered entirely by its own food waste

By - July 23, 2014
It's an unfortunate fact that every day around the world, supermarkets throw out tons of food that has spoiled before it could be purchased. While it would be best if that spoilage could be avoided in the first place, British grocery chain Sainsbury's is taking what might be the next-best approach – it's about to start using that unsellable food to power one of its stores.

Moth eyes inspire more efficient photoelectrochemical cells

By - July 17, 2014 3 Pictures
As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.

Net-zero energy test home ends year-long study with surplus energy

By - July 10, 2014 8 Pictures
Braving a harsh winter with snow-covered solar panels, the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has come up trumps in a year-long study of its energy harvesting capabilities. Located on campus at the National Institute of Standards and Technology (NIST), researchers used computer simulation to replicate the energy consumption of a family of four. At the end of its first 12 months, there was a large enough surplus to power an electric car for 1,440 miles (2,317 km). Read More
