Superconducting Power Grid Launches in New York

EmagGeek writes: "There is an article in IEEE about a new superconducting power grid that was energized in April in New York State. The lines operate at 138kV and are cooled to 65-75K to maintain superconductivity. These lines are run underground and can carry 150 times more electricity than copper lines of the same cross section (the article didn't say if they meant current or energy). The project is funded with taxpayer dollars through the Department of Energy."
