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 10 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. 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 6 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 3 weeks ago

Last year, astrophysicist Steve Tomczyk of the National Center for Atmospheric Research in Boulder, Colo., and his colleagues asserted that corkscrew-shaped Alfven waves were converting the motion energy of the sun's roiling material into heat.

But the authors of the new study argue that the waves Tomczyk's team saw were not Alfven waves but kink waves. picked by deepchill 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 5 months ago
