Samsung Unveils LCD Monitor That Powers Itself Solely From Your PC's USB
Samsung has unveiled a 18.5-inch LCD display that consumes only 6.3W. The announcement, made at SID 2010, has been accompanied by a demonstration in which such a display was powered only via a USB 2.0 cable from the PC it was linked to!
Southern California Implementing 53 MW Ice Energy Storage for Air Conditioning Systems
Ice can be used to store energy (though the other way we may be tempted to think) just like hot bricks or molten salt. Several Southern California municipal utilities will be implementing ice-based energy storage devices to reduce the air conditioning consumption in government offices and commercial buildings. Over the next two years, they will install 6,000 devices at 1,500 locations, storing around 53 megawatts of energy in total.
HP Developing Flexible Solar-Powered Wristwatch For The U.S. Army
HP has started the development of a next-generation wristwatch for the U.S. Military. The wristwatch called â€Ã…“Dick Tracy†may eliminate the need for soldiers to carry backup batteries and cumbersome technological gear.
How to Measure a Stirling Engine's Efficiency (video)
The next video shows a Stirling engine while working to achieve its best, powered by a 70W light bulb. The poster also shows how he measured various parameters of the engine, like speed, torque, input/output power.
The Grey-Faced Buzzard: Asia's First Unmanned Aerial Vehicle Powered by Battery and Fuel Cell
The National Cheng Kung University in Taiwan has developed Asia's first unmanned aerial vehicle (UAV) called the Grey-Faced Buzzard. The green-powered UAV that made its maiden flight in Southern Taiwan is powered by lithium batteries and fuel cell.
Converting Plastic Waste into Clean Energy Without Releasing Harmful Emissions
Student scientists at Northeastern University have designed an apparatus capable to transform waste plastic into an alternative fuel without releasing harmful emissions.
Optical Fibers Mounted Upright on Organic Solar Cells Doubling Their Efficiency
Right now organic solar cells, although cheap, are too inefficient to compete with silicon-based ones. A team of researchers from Wake Forest University in North Carolina have developed a practical method of doubling the efficiency of organic (or dye-sensitized) solar cells by adding a layer of upright optical fibers acting as sunlight traps.
Electricity-Producing Shock Absorbers On Their Way to The Market This Summer
After sleeping for a while, energy-producing shock absorbers appear in the news again. Levant Power, a company from Massachusetts, produces such shock absorbers that are developed by Cambridge. The company claims that their product can lower fuel consumption by 1.5 to 6 percent, depending on the vehicle and driving conditions.
Paper-Printed Solar Cells Invented in MIT's New Solar Research Center
For the first time in history, scientists at the MIT have coated paper with a solar cell at the newly opened Eni-MIT Solar Frontiers Research Center. The coating technique is similar to that of an inkjet printer - the big difference is that the coating is this time a semiconductor, not ink.
Hydrophobic Coating Inspired by Water Ferns Could Make Ships Consume 10 Percent Less
Water ferns have tiny hairs that are superhydrophobic. Their properties, if applied in real life conditions to a sail boat, for example, could lead to a reduction of up to 10 percent of the boat's fuel consumption by reducing friction.
