The battery-size product, the M2E, harnesses kinetic energy, or normal physical movement, to generate power. Clipped onto a belt or carried in a knapsack, the entire generator is contained within a regular battery casing. The wearer's walking or shaking moves magnets in the device. Those magnets infuse the wire coils with energy that can be used to power mobile devices

eveals the question that occupies scientists at the end of the day (and the beginning of happy hour): How might the world end?

aptains would be able to throttle back the ship’s diesel engine and slash fuel consumption up to 50 percent in optimal conditions. The first cargo ship to be fitted with a kites from SkySails is the 460-foot Beluga SkySails owned by the Beluga Group.

The device works by cooling air quickly without using outside energy through a set of turbines. Wind blows through the turbines which then power a series of refrigerated plates. As the air passes over the plates, water condenses onto them and is shed quickly by forcing it to bead and roll into a water collection tank.

China and India's growth is a "legitimate aspiration that needs to be accommodated and supported by the rest of the world"

alled the HB-SIA, the prototype aircraft consists of wing covered with solar cells with a span of 200 feet. Despite that huge wing span, the craft will employ lightweight materials to tip the scales at only 3,300 pounds. That combination will allow the plane to fly at just 28 miles per hour, a speed that will keep energy consumption low, allowing the solar panels to not only power the craft during the day, but to also store up enough energy to keep it flying at night. Construction of the HB-SIA began in June and is expected to be complete by the summer of 2008.

The use of food as a source of fuel may have serious implications for the demand for food if the expansion of biofuels continues,' the International Monetary Fund said in its twice-yearly report on the world economy.

Each small three-foot bolt generates enough electricity to illuminate a 60-watt light bulb for 20 minutes. But a full-scale system, LeRoy believes, could power 30,000 homes for a day with just one lightning bolt. Given that the average Midwest thunderstorm releases enough electrical energy to power the entire U.S. for 20 minutes, who knows what the potential is for the harvesting of lightning fields and arrays of bolt conductors.

The Solar Decathlon joins 20 college and university teams in a competition to design, build, and operate the most attractive and energy-efficient solar-powered house.

They just announced that they have completed their first jet flight with their engines (for most of the flight) running purely on biodiesel. The details so far are sparse, but here's what they are saying: The experimental test flights were conducted starting with a blend of jet fuel and biodiesel. The engine data was measured and the performance was evaluated and found acceptable for continued use, eventually resulting in the landmark flight using 100% renewable biodiesel fuel

The viability of electric cars is set to take a giant leap forward after energy giant EDF announced it is to install 250 recharging stations across the UK by April 2008. The company is to join forces with recharging station manufacturer Elektromotive to provide the recharging stations, which it claims will make electric cars such as the G-Wiz and MEGA City more attractive propositions for urban commuters.
