Superconductivity near room temperature
> "Materials known as superconductors transmit electrical energy with 100% efficiency."<p>What is the level of (in)efficieny for say power lines? And power cords, etc around the office/house?<p>That is, of the electricity produced, how much is lost due to how it's transported? Does decentralizing production (e.g., solar panels on your own roof) help in any way?
