Re: Infinite Electricity
As of October 2007, the highest temperature superconductor is a ceramic material consisting of thallium, mercury, copper, barium, calcium, and oxygen, with Tc=138 K.
In February, 2008, another different family of high temperature superconductors was discovered. Hideo Hosono of the Tokyo Institute of Technology and colleagues found that lanthanum oxygen fluorine iron arsenide (LaO1-xFxFeAs) becomes a superconductor at 26 kelvin. Other researchers quickly found other materials in the same family that have transition temperatures as high as 55K. Experts hope that having another family to study will simplify the task of explaining how these materials work.
