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 1 year ago

Galaxies today are struggling to clump together against the incredible repulsive power of dark energy, hints a new survey of thousands of galaxies. Measuring this anti-clumping effect puts a new arrow in the quiver of cosmologists seeking to uncover the nature of the mysterious force. picked by deepchill 10 months ago

One of the most widespread misconceptions out there is that a higher power supply unit will automatically mean a higher energy consumption and of course a higher power bill. picked by maxriter 1 year 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 4 months ago

"Reading this, your body at rest is emitting about 100 watts into the environment. If you're sitting in an open plan office, count the number of surrounding colleagues and you don't need to be a maths genius to appreciate the possibilities of tapping into all that wasted energy. Instead it could provide a renewable energy source to power office lighting or laptops - and it may be possible ... read full post picked by Jetka 10 months ago

A revolutionary device that can harness energy from slow-moving rivers and ocean currents could provide enough power for the entire world, scientists claim.Existing technologies which use water power, relying on the action of waves, tides or faster currents created by dams, are far more limited in where they can be used, and also cause greater obstructions when they are built in rivers or the sea... read full post picked by smantyla 3 days 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 month 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 5 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 12 months ago

Meet the standard British electrical socket; actually designed with an on/off switch. Many electrical appliances draw electricity even when they’re turned off. Here’s the euro solution: Every electrical socket in my flat here in the UK has an on/off switch. Imagine how much energy we could save if we cut off the electricity to every socket not in use. This is cutting down on wasted ene... read full post picked by pitim 1 year ago
