Porsche 911 GT3 R Hybrid Using 160hp Flywheel for Its Electric Motors
Porsche has already been recognized all over the world as building quality performance cars, despite their "heavy" price and big engines. It looks like now Porsche is trying to green itself out and use an innovative hybrid technology based on a flywheel, installed in a racing car.
Semprius's Micrometric Solar Cells Efficient in Concentrated Photovoltaic Systems
Concentrated photovoltaic systems are usually more effective than regular, flat ones, because a lens focuses the sunlight on a smaller surface of some efficient and more expensive solar cells 500 times stronger than the cells would receive in regular operation. Heat is mostly a problem with concentrated PV systems, since it has to be efficiently dissipated through complex and expensive cooling technique.
World's Smallest Solar Powered Sensor Invented by University of Michigan Researchers
University of Michigan engineers developed the smallest solar powered sensor system, having only 9 cubic millimeters, that can harvest energy from ambient light to operate.
Scientists Develop a Quantum-Dot Process to Split Water and Generate Hydrogen
Fuel cells can be used in various applications such as spacecraft, remote weather stations, large parks, rural locations, military applications and automotive industry. Fuel cells have hydrogen as the base element for their power.
Utah-Based Company Digging Underground Compressed Air Batteries
Underground caverns may have never been seen as energy containers, but a Utah-based private equity group promises to use them filled with compressed air to generate electricity the classic way - by spinning a turbine.
Composite Nanomaterial Could Transform The Car's Body Into a Battery
The interesting fact is that the material resembles a fabric, and can be shaped into different objects, so maybe in the future mobile phone users won't have to have a battery in their cellphone, just because its case will do the job.
Self-Powered Solar Circuit Could Help Computing Become Greener and Faster
A team of scientists at the University of Pennsylvania have developed the world's first circuit powered by solar energy that can power itself, as long as it's left in a beam of sunshine. It could eventually power a new line of consumer devices or even model the human brain.
Japanese Thermoelectric Modules Aim Reaching Record of 11% Efficiency
A new test will be performed by Showa Denko on Feb. 15, 2010. The thermoelectric device is designed to be attached to the exhaust pipe of a car and supply electricity to the car's air conditioner, thus improving the fuel mileage.
Astounding Discovery: Marine Algae Using Quantum Mechanics Principles for Light Harvesting
Professor Greg Scholes, the lead author of the study published recently in Nature, says: "There's been a lot of excitement and speculation that nature may be using quantum mechanical practices. Our latest experiments show that normally functioning biological systems have the capacity to use quantum mechanics in order to optimize a process as essential to their survival as photosynthesis."
Sixtron's Antireflective Coatings Solve Safety and Efficiency Issues in Solar Cell Technology
Up to now, the most used antireflective coating method has been the vapor deposition of a silicon nitride film by using a highly-flamable silane gas, which can ignite when exposed to air. Transporting, storing, ventilating silane gas and other safety-keeping operation make the process very expensive.
