What smart grid visionaries see coming are home thermostats and appliances that adjust automatically depending on the cost of power; where a water heater may get juice from a neighbor's rooftop solar panel; and where on a scorching hot day a plug-in hybrid electric car charges one minute and the next sends electricity back to the grid to help head off a brownout. picked by kakana 6 months ago

As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment. picked by AutumnLotus 2 years ago

The next time you change a bike tire, think about upgrading your power as well. Scientists at MIT are testing a new power generation, storage and propulsion system known as the GreenWheel that will turn any pedal bicycle into an electric hog. picked by AutumnLotus 9 months ago

Veranda Solar is readying a solar panel that is able to be plugged into a standard home outlet, putting power directly into the system, where duplex plugs are the norm. And it can cost as little as $600. picked by mattgup 9 months ago

Siemens, the electronics and electrical engineering global powerhouse, unveiled the Smart Chopper it commissioned. The bike has a 60-mile range and a 100 mph top speed. An onboard charging unit can be plugged into any 110-volt socket to charge the bike in five hours, and it’ll charge in as little as one hour when plugged into a higher-voltage station. A single-speed, clutch-less transmission... read full post picked by Bingo 4 months ago

A new Taser that fires wireless electric shock projectiles up to 30 metres is being considered for use by UK police forces, the Home Office has confirmed.

But Amnesty International said it was "seriously concerned" about the XREP and worried by the news it could be authorised in the UK picked by Doggylives 3 months ago

California's electricity grid manager warned that power to large energy consumers is likely to be cut later Thursday to keep the state's lights on. picked by Bornbad 2 years ago

A man had to deliver some sand.

Unfortunately there were power lines in the way.

Fortunately his truck fit under the power lines.

Unfortunately he raised the back of the dump truck, hit the power lines, and set his truck on fire.

Fortunately he was already at the fire station.

Unfortunately they had to watch the truck burn for 45 minutes until the power could be shut off. picked by Fanatic 3 years ago

"In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine." picked by ybcool 1 year ago

Scientists have managed to harness the energy-producing power of hamsters by fitting them with tiny detector jackets.

The devices are strapped to the animals as they run on their cage wheels, capturing the biomechanical energy they release as they exercise. picked by AutumnLotus 9 months ago

One of wind powers drawbacks is no one wants it to mar their view. They want it to mar someone elses of course. Placing the turbines far off shore could help alleviate the problem. picked by 2manyusernames 1 year ago
