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 11 months ago

Denmark, a world leader in wind energy production and consumption, has built the world’s largest offshore wind park in the North Sea as it aims to generate 75 percent of its electricity needs with wind power by 2025. picked by AutumnLotus 1 year ago

Using concentrated solar energy to reverse combustion, a research team from Sandia National Laboratories is building a prototype device intended to chemically “reenergize” carbon dioxide into carbon monoxide using concentrated solar power. The carbon monoxide could then be used to make hydrogen or serve as a building block to synthesize a liquid combustible fuel, such as methanol or ev... read full post picked by AutumnLotus 9 months ago

US Air Force may soon be refueling tiny spy planes by stealing energy while hanging from power lines. It could even temporarily change its shape to look more like innocuous piece of trash hanging from the cable. picked by 2manyusernames 8 months ago

Introducing the family car that runs on hydrogen and pumps out only pure water from its exhaust pipe.

Honda's FCX Clarity is the world's first production hydrogen-powered 'fuel cell' car - with its own onboard power station which creates electricity to drive its motor. picked by AutumnLotus 2 months 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 2 years ago

A new energy concept called a solar tower could generate enough electricity for 200,000 homes. Looking like a giant smokestack, it would release no noxious fumes — just sun-heated air. picked by deEPCHIll 2 months ago

The station has offset its electricity with 100 percent certified energy certificates, according to station officials.

That means every bit of power used at the studios on the 2400 block of North First Street in San Jose is replaced on the grid by clean energy created by wind farms. picked by johnnytitan 6 months ago

Galaxies today are struggling to clump together against the incredible repulsive power of dark energy, hints a new survey of thousands of galaxies.
