Li-ion Batteries Last Three Times Longer with SiO2 Anode

Written by , on May 29, 2014

Researchers at the University of California have developed a new way to make lithium-ion batteries, using a common material, that will last three times longer between charges compared to the current industry standard.  Read more »

New Way of Generating Electricity from Heat

Written by , on May 27, 2014

Researchers at MIT and Stanford demonstrated a new way to transform waste heat into electricity, particularly in situations where the temperature gradient is small.  Read more »

Dual-carbon Battery – Safer, Longer Life & Charges Faster

Written by , on May 15, 2014

The Japanese company Power Japan Plus has announced that it has development a carbon battery that can be charged 20 times faster than an ordinary lithium-ion cell, is cheap to manufacture, safe and environmentally friendly. The company says that it is planning to mass-produce its “dual-carbon” battery which would be ideal to improve the range and charging times of electric cars.  Read more »

Aviation Fuel from CO2, Water and Sunlight

Written by , on May 10, 2014

The Solar-Jet project has successfully demonstrated the entire production chain for renewable kerosene obtained directly from just sunlight, water and carbon dioxide captured from the air. The process also has the potential to produce other types of fuel, such as diesel, gasoline or pure hydrogen, for transport applications in a more sustainable way. The project […]  Read more »

Efficient New Solar Cell Material Can Also Emit Light

Written by , on April 27, 2014

Scientists at Nanyang Technological University have developed a solar cell material which can emit light as well as converting light to electricity. The new cells not only glow when electricity passes through them but they can also be customised to emit different colours.  Read more »

New Wind Turbine Design Based on Bird Wings

Written by , on April 15, 2014

The German industrial automation and control company, Festo, has developed a dual wing generator. In contrast to conventional small wind power stations, the system uses two pairs of opposing wings instead of rotor blades to generate power.  Read more »

Energy Dense “Biobattery” Runs on Sugar

Written by , on March 18, 2014

A research team at Virginia Tech university, led by Professor Y.H. Percival Zhang, has developed a sugar-powered fuel cell that stores ten times as much energy as the equivalent-size lithium-ion battery. The new sugar-powered cell has an energy density an order of magnitude higher than previous “”biobatteries” – allowing it to run longer before needing to […]  Read more »

Storing Energy in Silicon Cells

Written by , on March 17, 2014

Researchers at Vanderbilt University in Nashville have devised a way to store electricity on a silicon-based supercapacitor that potentially would let mobile phones recharge in seconds and continue to operate for weeks without recharging. Whereas batteries store energy in chemical reactions, supercapacitors store electricity by assembling ions on the surface of a porous material. As […]  Read more »

More Efficient, Self-cleaning Solar Cells

Written by , on March 17, 2014

Researchers from Changchun University of Science and Technology, Xi’an Technological University and Cardiff University have found that a patterned layer on top of the active part of a solar panel can avoid the energy losses due to reflection from the surface. They have devised an approach to the lithographic process used to “print” microelectronic circuits […]  Read more »
