Helping superconductors turn up the heat
Researchers from the University of Miami (UM) are unveiling a novel theory for high-temperature superconductivity. The team hopes the new finding gives insight into the process, and brings the scientific community closer to achieving superconductivity at higher temperatures than currently possible. This is a breakthrough that could transform our world. Superconductors are composed of specific […]
Catching some rays
Solar cells make a leap forward Drawn together by the force of nature, but pulled apart by the force of man – it sounds like the setting for a love story, but it is also a basic description of how scientists have begun to make more efficient organic solar cells. At the atomic level, organic […]
ORNL microscopy reveals workings behind promising inexpensive catalyst
A newly developed carbon nanotube material could help lower the cost of fuel cells, catalytic converters and similar energy-related technologies by delivering a substitute for expensive platinum catalysts. The precious metal platinum has long been prized for its ability to spur key chemical reactions in a process called catalysis, but at more than $1,000 an […]
Environmental benefit of biofuels is overestimated, new study reveals
Two scientists are challenging the currently accepted norms of biofuel production. A commentary published today in GCB Bioenergy reveals that calculations of greenhouse gas (GHGs) emissions from bioenergy production are neglecting crucial information that has led to the overestimation of the benefits of biofuels compared to fossil fuels. The critique extends to the Life Cycle […]
Photovoltaic cells tap underwater solar energy
WASHINGTON — Scientists at the U.S. Naval Research Laboratory (NRL), Electronics Science and Technology Division, dive into underwater photovoltaic research to develop high bandgap solar cells capable of producing sufficient power to operate electronic sensor systems at depths of 9 meters. Underwater autonomous systems and sensor platforms are severely limited by the lack of long […]
Energy sector expected to drive growth in the screw jack market
IMS Research forecasts continued stable growth in the screw jack market over the next five years. The global screw jack market is mature and has had a low single digit growth profile in recent years. Screw jacks perform important handling and lifting functions in industry, civil transport and energy sectors. According to the IMS Research […]
Four-Watt, AC/DC power supplies meet “green power” requirements
The MPM-04E Series, available now from MicroPower Direct, is a family of low cost, single and dual output 4W AC/DC power supplies. These compact modules are specifically designed to meet the “Green Power” requirements of the ErP directive while providing the small size, robust performance and economy required by many board level power applications. Ten […]
Slip-and-slide power generators
Researchers from Vestfold University College in Norway have created a simple, efficient energy harvesting device that uses the motion of a single droplet to generate electrical power. The new technology could be used as a power source for low-power portable devices, and would be especially suitable for harvesting energy from low frequency sources such as […]
Solar plane begins 1st transcontinental flight
GENEVA (AP) — An experimental solar-powered airplane took off from Switzerland on its first transcontinental flight Thursday, aiming to reach North Africa next week. Pilot Andre Borschberg planned to take the jumbo jet-size Solar Impulse plane on its first leg to Madrid, Spain, by Friday. His colleague Bertrand Piccard will take the helm of the […]
