Optical fibers power mobile data networks

Researchers at the University of Electro-Communications,Tokyo, report the ability to supply 60 watt power over a 300 meter optical fiber system, demonstrating the potential of optical feed systems using double-clad fibers ...

Power lines restrict sage grouse movement in Washington

Transmission lines that funnel power from hydroelectric dams and wind turbines across Eastern Washington affect greater sage grouse habitat by isolating fragile populations and limiting movement, a new study finds.

Power lines offer environmental benefits

Power lines, long considered eyesores or worse, a potential threat to human health, actually serve a vital role in maintaining the health of a significant population, according to new research out of the University of Connecticut.

Connecting dead ends increases power grid stability

Climate change mitigation strategies such as the German Energiewende require linking vast numbers of new power generation facilities to the grid. As the input from many renewable sources is rather volatile, depending on how ...

CERN: World-record current in a superconductor

In the framework of the High-Luminosity LHC project, experts from the CERN Superconductors team recently obtained a world-record current of 20 kA at 24 K in an electrical transmission line consisting of two 20-metre long ...
