Case Western Reserve University Could be woven into clothes to power wearable medical, communications devices Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics. The device is a supercapacitor—a cousin to the battery. This one packs an interconnected network of graphene and carbon nanotubes so tightly that it stores energy...

Tiny Flexible Power Supply
2013-08-07 16:03:26

Peter Suciu for redOrbit.com - Your Universe Online Searchers from the Royal Society of Chemistry have created a tiny power supply that is made of a flexible material. This powerful micro-supercapacitor is just nanometers thick - or thin, as the case may be - and this could help electronics companies develop devices such as mobile phones and cameras that are smaller, lighter and thinner than ever before. The bottleneck for making smaller electronic devices such as mobile phones has been...

Brett Smith for redOrbit.com - Your Universe Online Engineers from Oak Ridge National Laboratory (ORNL) have announced the successful testing of an all-solid lithium-sulfur battery with about four times the energy density of today´s lithium-ion batteries. Energy density is defined as the amount of energy stored in a system per unit of volume. "Our approach is a complete change from the current battery concept of two electrodes joined by a liquid electrolyte, which has been used...

Word of the Day
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
