Big magnets, for MRI, and for trains. Maybe flying cars :)
Run a big, refrigerated line (or just dig underground where it's cooler), and you can transmit unlimited power coast-to-coast, or even around the world. You could put some big nuclear power plants in the middle of a desert (or several deserts, to reduce the risk of a failure taking out the world's power supply), and a wind/solar grid around the world, and send that power anywhere. They are already building this kind of thing (Tres Amigas SuperStation), but it's expensive and small-scale.
- ramchip 16y agoWouldn't you still hit a wall due to the maximum field in the superconductor? I'd expect the wires needed to transport gigawatts of power to be pretty large and require exotic metals to build, so much that it may not make economic sense compared to a regular, slightly lossy wire.
