A recent discovery in a study of room-temperature superconductivity, if borne out, could make the dream of super-efficient long-distance electricity transmission and levitating trains a little closer ...
Researchers in Germany have claimed a breakthrough: a material that can act as a superconductor — transmit electricity with zero resistance — at room temperature and above. Superconductors offer huge ...
Here’s an interesting recipe. Take a spoonful of graphite powder and stir it into a glass of water. Leave for 24 hours at room temperature and then filter the powder. Finally, bake overnight at 100 ...
