Future wind-turbine farms

The Yokohama Renewable Energy International Exhibition 2010 earlier this month revealed some visually spectacular new designs for wind turbine technology. The Wind Lens has the potential to triple the amount of electricity produced by offshore turbines according to experiments. Kyushu University professor Yuji Ohya spoke of the merits of the 112-meter diameter structures being able to increase energy output “two or three fold”, as well as being about to reduce the dreaded noise pollution so often associated with wind turbines, and improve safety too.

20x More Energy From Sewage…By Adding Gold?

An energy bonanza?

Sewage is a surprising resource when it comes to harvesting energy during its treatment. According to researchers from Oregon State University, investing a little more in sewage could provide substantially bigger yields. They’ve found that adding gold nano-coatings to the anode chamber of a fuel cell could help produce 20 times more electricity from sewage treatment. The findings could mean bid news for combining wastewater with renewable energy generation.

Brother Industries Shaking Up the Battery World with Vibration-powered Batteries


Vibration-powered Generating Battery

Brother Industries Ltd developed small vibration-powered generators that can replace AA and AAA batteries.  For example, when the generator, which the company calls “Vibration-powered Generating Battery,” is set inside a remote control, it is possible to use the remote by shaking it to generate power.

RAPS (Remote Auxiliary Power System) Lets You Steal Electricity From Power Lines


powerline_hook 2222

Score power from your neighbor!

Check out this neat device called RAPS designed and created by Dave Coates of Dayton, OH.
RAPS was originally created so that Air Force personnel in the field could suck electricity out of power lines and recharge their equipment. The device is a hook that pierces a power line’s outside layer and then converts the AC power into DC power for consumer devices. Looks easy to use. [via]


Makeshift DIY AC Batteries Power Your Electronics

AC Battery Oiwer

Batteries adapted to AC Power saves $

It’s expensive replacing batteries for devices that don’t have an AC adapter socket, but if you’ve got a little time you can make your own AC-powered “batteries” that will power your device without heavy modification.

Instructable user lspcrash found that his camera ran through batteries like water, but his camera didn’t come with a DC input adapter which made it impossible to use a normal AC power source. Instead, he strikes gold by running AC adapter wire ends to specific contact points, powering the camera. It’s a cheap, effective fix that requires little modification to your device.

Say Hello to The World’s Most Advanced Electric Motorcycle

The future on two wheels.
The technology behind the MotoCzysz E1pc isn’t just the future for motorcycles, it’s the future of electric vehicles. When you have 10x the battery power of a Prius and 2.5x the torque of a Ducati it’s easy to see why.Michael Czysz, the man behind the machine, has made the MotoCzysz E1pc so advanced that all the major parts of the E1pc—from its motor to its battery packs to even its aerodynamics—are all new and class leading. The battery, obviously key in any electric vehicle, is connected without wires and thus can be easily swapped out in seconds. The batteries are hand assembled by a company that develops for NASA and its electric motor runs at nearly 500 volts which is powerful enough to turn a wrench into a pile of molten metal. The motor, called “D1g1tal Dr1ve,” offers a nearly direct connection between the throttle and rear wheel, which allows it to be nastily fast.

Medical Devices Powered by the Patient’s Own Heart


A single zinc oxide nanowire can be attached to a heart, where it produces electric current as it bends with every beat.

A tiny, nearly invisible nanowire can convert the energy of pulsing, flexing muscles inside a rat’s body into electric current, researchers at Georgia Institute of Technology have shown. Their nano generator could someday lead to medical implants and sensors powered by heartbeats or breathing.

Researcher Shows How the Next-Generation Smart Energy Grid can be Hacked


Smart meter

One researcher shows how your house’s power could be shut down remotely, but the threat is only theoretical–for now. Components of the next-generation smart-energy grid could be hacked in order to change household power settings or to spoof communications with a utility’s network, according to a study of three pilot implementations.

MIT Analysis Suggests Large-Scale Wind Farms Could Impact Climate


Wind farm

Wind power has emerged as a viable renewable energy source in recent years — one that proponents say could lessen the threat of global warming. Although the American Wind Energy Association estimates that only about 2 percent of U.S. electricity is currently generated from wind turbines, the U.S. Department of Energy has said that wind power could account for a fifth of the nation’s electricity supply by 2030.

It’s not often that a press event at the American Association for the Advancement of Science Meeting features a car. But the car that was driven into the press room today was an electric one, with some added communications skills: it could talk with the electric grid…
