Dexim's DVA004 Power Case for Apple's iPod 5G

China's consumer electronics manufacturer Dexim has announced the release of a multi-functional power case to complement the new iPod Nano 5G. Coming with a powerful flashlight to help shoot video in low light conditions, a built-in speaker for desktop listening and an antenna for improved FM radio reception, the DVA004 will also gives extended play courtesy of its lithium battery pack.  Read More

Dexim's solar-powered P-Flip power pack was launched at CES 2010

Dexim has launched five new accessories to be used with the iPod, iPhone and BlackBerry at CES 2010. One of the more clever offerings is the solar-powered P-Flip foldable power pack. The power pack can be flipped horizontally or vertically for hands-free viewing and is capable of extending talk time by up to eight hours.  Read More

Fully autonomous wireless temperature sensor powered by a vibrational energy harvester

Working within the Holst Centre program on Micropower Generation and Storage, researchers have developed a small piezoelectric device capable of harvesting 85 microwatts of electricity from vibrations. Fabricated using MEMS technology, the fully autonomous temperature sensor generates enough power to wirelessly measure and transmit environmental data to a base station every 15 seconds.  Read More

Researchers have discovered that common bacteria suspended in a solution can be made to turn microgears. This opens up the possibility of building hybrid biological machines at the microscopic scale. The researchers say the discovery demonstrates how microscopic swimming agents, such as bacteria or man-made nanorobots, in combination with hard materials, can constitute a "smart material", which can dynamically alter its microstructures, repair damage, or power microdevices.  Read More

The GREENS solar panels can be rapidly deployed in the field to provide front line forces ...

In response to a Marine Corps requirement from Iraq for an expeditionary renewable power system, the Office of Naval Research (ONR) Advanced Power Generation Future Naval Capabilities program has introduced technology designed to harness some of the sunlight that beats down upon U.S. Marines operating in the Arabian Desert. Fueled by the sun, the Ground Renewable Expeditionary ENergy System (GREENS) is a portable, 300W, photovoltaic/battery system that provides continuous power to marines in the field.  Read More

The Oyster wave energy device was launched this week by Scotland's First Minister Alex Sal...

Rounding off a big week in renewable energy is news that the world’s largest working hydro-electric wave energy device has been officially launched in Scotland. Known as Oyster, the device, stationed at the European Marine Energy Center (EMEC) Billia Croo site near Stromness, was installed this year and is, at present, the world’s only hydro-electric wave energy device which is producing power.  Read More

Using the new technology automobiles and aircraft, like this Airbus A380, could harness cu...

Previously, we’ve looked at technology to generate electricity from roads embedded with piezoelectric crystals that produce electricity when squeezed. Now a group of researchers is looking to shift the technology from the road to the vehicles themselves and use piezoelectrics placed on the vehicles to convert their kinetic energy into electricity.  Read More

The ocean is a potentially vast source of electric power, yet wave-energy systems are rare as they generally offer limited efficiency, must withstand battering storms, and need to be tethered to the sea floor. But by applying the principles that keep airplanes aloft, a team of aerospace engineers is creating a new wave energy system that is durable, extremely efficient, and can be placed anywhere on the ocean, regardless of depth.  Read More

A laptop generating a little too much waste heat (Photo: secumem via Wikipedia Commons)

That heat emanating from your computer as you sit reading this article amounts to nothing more than wasted energy. And your computer is not alone. More than half of the energy consumed worldwide is wasted, most of it in the form of excess heat. But new research at the Massachusetts Institute of Technology (MIT) indicates it might be possible to harvest much of the wasted heat produced by everything from computer processors to car engines and electric powerplants, and convert it into usable electricity. This kind of waste-energy harvesting might lead to mobile phones with double the talk time, laptop computers that can operate twice as long before needing to be plugged in to mains power, or energy plants that produce more electricity for a given amount of fuel.  Read More

The Shelf solar sunshade - can collect enough solar energy to power a vehicle's air condit...

As the motoring world moves ever-closer to the welcome infiltration of electrically-powered cars, one thing holding them back is the availability of charging stations to “refuel” the vehicles which so far have an average range of around 120 miles between charges. The Shelf, a concept by Chinese designer Leon Zhu, takes advantage of the sun’s solar energy and collects enough of the stuff on a hot day to power the car’s air conditioner, tail lights and other electronic equipment, therefore extending the life of the car’s onboard batteries. What’s more, the solar panel protects your vehicle’s expensive duco from long exposure to the sun. Just don’t try to extend the solar panel while you’re driving.  Read More
