The Napa Winery Making Hydrogen from Grape Wastewater
Napa Wine Company in Oakville found an interesting way of producing hydrogen by using the winery's own wastewater, using naturally-occurring bacteria and a small amount of electricity to extract hydrogen the organic material they usually throw away,with a generator the size of a refrigerator.
Israel Highway Equipped With Pilot Piezoelectric Generator System
Yesterday morning, the Hefer intersection along the old coastal road of Route 4 in Israel was the place where a piezoelectric generator was put to the test and generated some 2,000 watt-hours of electricity. The setup consists of a ten-meter strip of asphalt, with generators lying underneath, and batteries in the road's proximity.
Toshiba to Release New Home LED Lighting Devices on Oct. 16
With small steps, LEDs entered in the home and industrial lightning, as well. Toshiba Lighting & Technology Corp will soon release a high-output LED light bulb which power will be equivalent of an incandescent bulb of 60 W.
IBM Chooses Lithium Air Batteries for 500 Miles EV Range
IBM, through its "Big Green" - "Battery 500" project, aimed to produce a battery for an electric car that would be able to carry a family-sized sedan up to 500 miles, spotted the lithium-air (STAIR) invention as its goal, and predicted that they could improve the STAIR battery further with the nanoscale semiconductor manufacturing techniques they possess.
Scientists Researching Fuel Cell Powered by Sugars
Researchers from Brigham Young University have a plan to make different fuel cells than those we actually know, and turn them into something very efficient and reliable. Their goal is to make a cheap fuel cell with a cheap catalyst, which can be even more efficient than a PEM and which can use something easier to make and store than hydrogen and which has no net emissions.
Lithium-Polymer Based Battery System for Solar-Powered Homes
A Malaysian company called ETI Tech Corporation Bhd has developed the world's first lithium-polymer battery system for solar-powered homes. â€Ã…“The lithium ion battery is 100 per cent environment-friendly, unlike the more commonly used lead acid battery,†said ETI Tech Corporation Bhd managing director K. K. Lee.
Helix-Shaped Vertical Wind Turbines Will Power GSM Towers in Africa & US
Too often, regardless of the energy sources being used, the GSM transmission towers' power fails, because of various reasons: theft, heavy rain/snow, disturbances in the grid lines. Helix, a San Diego-based wind company, is working on a wind turbine that is designed to power base stations in hard to reach, remote locations from Africa and the US.
30% Efficiency with Gallium-Nitride Silicon Solar Cells
The Phoenix-based company RoseStreet Labs Energy has developed a prototype solar cell that combines gallium-nitride with silicon, a technology that achieves an efficiency of 25 to 30 percent.
Clean Hydrogen Obtained Through Thermolysis of Water by H2 Power Systems
H2 Power Systems, based in the UK, has designed an on-site and on-demand hydrogen producing system based not on electrolysis, but on thermolysis, which is the splitting of water at very high temperatures.
New Nanostructure Film Reduces Solar Cells Reflection for Better Efficiency
Oregon State University engineers have innovated a new nanostructure film technology that they can deposit on any surface and reduce the reflectance of light. Their technology should perform better and have a lower price.
