Superconductors won't play a role in energy transport until their installation and operational costs over their lifetime are less then the installation, operational costs and losses of legacy conductors.
- ben_w 6y ago> they are just a few percent to begin with To be more precise, losses are exponential with regard to distance. “A typical loss for 800 kV lines is 2.6% over 800 km”[0], which would be close to 60% losses between antipodes[2]. I think that’s still plausibly worth doing, given renewable prices[1], but it’s not great if you can avoid it.
