Ultrathin Device harvests electricity from Human Motion

A new, ultrathin energy harvesting system developed at Vanderbilt University has the potential to power your cell phone, fitness tracker and other personal electronic devices as you walk, wave and even when you are sitting down. Based on battery technology and made from layers of black phosphorus that are only a few atoms thick, the … Continue reading “Ultrathin Device harvests electricity from Human Motion”

First Battery-Free Cellphone makes calls by harvesting ambient power

University of Washington researchers have invented a cellphone that requires no batteries — a major leap forward in moving beyond chargers, cords and dying phones. Instead, the phone harvests the few microwatts of power it requires from either ambient radio signals or light. The team also made Skype calls using its battery-free phone, demonstrating that … Continue reading “First Battery-Free Cellphone makes calls by harvesting ambient power”

Solar Impulse 2 Completes Historic Trip Around The World Without A Drop Of Fuel

The experimental zero-fuel aircraft, Solar Impulse 2, has completed the final leg of its global circumnavigation attempt. It is the first circumnavigation of the world by a piloted fixed-wing aircraft using only solar power. The Solar Impulse prototype has already set eight world records, including first solar aeroplane to fly through the night, between two … Continue reading “Solar Impulse 2 Completes Historic Trip Around The World Without A Drop Of Fuel”

Scientists increases the energy efficiency of solar fuels production from 18% to 22%

Researchers at Monash University have designed a solar fuel generating device that has established a new record in energy efficiency for the production of solar fuels. The new device can produce hydrogen fuel at 22 per cent energy efficiency, breaking the previous record of 18 per cent. Professor Leone Spiccia explained that the process of … Continue reading “Scientists increases the energy efficiency of solar fuels production from 18% to 22%”

New solar flow battery achieves 20% energy savings over traditional batteries

After debuting the world’s first solar air battery last fall, researchers at The Ohio State University have now reached a new milestone. Researchers at The Ohio State University have invented the prototype of a new patent-pending device, “aqueous solar flow” battery—which combines a solar cell and a battery into a single device—now achieves a 20 … Continue reading “New solar flow battery achieves 20% energy savings over traditional batteries”
