Improving the technology of superconductors, already used in the Large Hadron Collider and MRI machines, would revolutionize our everyday life. Here’s how.
For long range cable it doesn’t even need to be so cheap. If you can transport cheap solar electricity nearly without losses from the equator to more polar regions, that could be economically feasible already. Doesn’t need to connect every house with that material, just the big distances between generating and using regions.
Lossless electrical transmission, tho deployment depends of financial viability of course, so the material would need to be relatively cheap
