GM to Research Shape Memory Alloy for Heat Recovery Systems
GM's R&D has to build a prototype of a thermo-mechanical waste heat recovery system using a Shape Memory Alloy (SMA) heat engine to generate electricity from the heat in exhaust. Noticeable is the fact that GM was between the 37 other candidates that received the ARPA-E award.
Solar Impulse Aircraft to Make the First Solar-Powered Flight Around the World
The Solar Impulse aircraft, officially known as HB-SIA, successfully underwent its first engine run up on Friday at an airbase near Zurich in Switzerland. It is designed to make the first solar-powered flight around the world.
Swing Door WaveRoller Generates Up to 300KW of Energy in the Surge Zone
One of the simplest ideas of harvesting the ocean power was developed by Rauno Koivusaari, a fin diver who got inspired by exploring the depths of the seas and lots of shipwrecks.
EarthSure's Wind & Solar Powered Electric Car: Would It Work?
EarthSure, an innovator in alternative energy sources and renewable energy company is planning to develop a zero-emission electric vehicle powered by solar and wind energy. Called AirRay, the new car will be equipped with four wind turbines and a solar roof. All of these to generate necessary electricity to keep the batteries charged up.
Metal-Air Ionic Liquid Battery: 11 Times The Capacity of Li-Ion
A spinoff company from Arizona State University is planning to develop a metal-air battery which unlike lithium-ion batteries has an energy density 11 times greater, for less than one-third the cost. Last week, the US Department of Energy awarded a $5.13-million research grant to Scottsdale, AZ-based Fluidic Energy. This company hopes that its ultra-dense energy storage technology to become reality.
New Solar Farm That Generates Electricity Even After Sunset
The new solar farm will be based on the use of 17,500 large mirrors called heliostats which will be arrayed in a circle around a 538-foot concrete tower. Each one will measures between 24 - 28 feet, being attached to 12-foot pedestals.
Bulk Fluid-Processed Carbon Nanotubes Could Make Better Power Lines
Scientists at Rice University have developed a new method for producing carbon nanotubes in bulk fluids. It could lead to revolutionary advances in nanoelectronics, materials science and power distribution.
Torotrak's Flywheel System Could Be Cheaper Alternative to Hybrid Car Batteries
Flywheels are known to be very good mechanical energy storage devices. They have a certain weight and, by spinning, they capture the energy in their momentum. That energy can be released by electromagnetic means and transformed into electricity.
Mirror-Based Solar Device as Cheap as Coal-Burning Electric Power Plants
Steward Observatory Mirror Lab from the University of Arizona has produced a prototype of a solar device that is able to produce energy at a price comparable with the cheapest fossil fuels.
Sharp Releases 450mW Solar Cell Module for Cellphones
Sharp Corp. has announced the development of an improved solar cell module for cellphones at Green Device 2009, a trade show that will be open to the public from Oct 28 to 30, 2009, at Pacifico Yokohama, Yokohama City, Japan.
