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.
Natural Gas Powered Fuel Cells Project Presented to US Congress
ClearEdge Power has addressed a proposal to the Congress for a new and interesting project. They found a way to obtain heat and power with fuel cells working on natural gas. The investment can be payed back after a six or seven year period as mentioned by Bill Sproull, senior vice president of the company.
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.
The Electric Car's Song
I heard this is a little old, but it fits into GreenOptimistic's subjects, and, there sure are people who haven't seen it.
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.
New Electronic Circuit Cooling System Offers Brighter Electric Car Perspectives
Researchers from Purdue University discovered precisely how fluid boils in capilary cooling sytems, and that by designing a system by using those rules they got a much more efficient heat transfer between the object to be cooled and the liquid.
