Heat-energy storage device could make household solar power more feasible

By - October 15, 2014
Although solar panels are active while the sun is shining, they typically don't do much once the sun goes down. This is why some systems incorporate water tanks. The water is heated during the day via the panels, then that stored thermal energy (heat) is used to warm the home at night. While the tanks are effective, they also take up a lot of space, making them difficult to fit into peoples' homes. A newly-developed device, however, stores just as much heat in half the space – using paraffin instead of water. Read More

University of Washington fusion reactor promises "cheaper than coal" energy

By - October 12, 2014
In the 21st century, the world lives with two futures ahead of it – one of looming energy shortages, and another of godlike energy abundance. The key to this whether it’s possible to turn fusion reactor technology from a laboratory exercise into a real-world application. Engineers that the University of Washington are working on a fusion reactor that, when scaled up, could produce energy on a practical scale, yet at a cost rivaling that of a conventional coal-powered plant.

MIT's improved all-liquid battery could make renewable energy more competitive

By - September 24, 2014 2 Pictures
Our ability to store energy has proven a big hurdle in the adoption of renewable energies. But now a team of researchers from MIT has developed a new all-liquid battery system that extends the life of such devices while also costing less to make, a development they say could make wind and solar energy more competitive with traditional sources of power.

Buddhist singing bowls could inspire highly efficient solar cells

By - September 14, 2014
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
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
