Lossless Power Grids
Superconducting cables carry electricity across continents without loss, and storage and magnets become cheap.
Open in the interactive tree →Power grids lose roughly 5 to 10% of energy on the way to consumers. A cheap superconductor that works at everyday temperature would remove that loss, allow compact high-power cables and make very strong magnets inexpensive.
What it brings
- Continental power transmission without losses
- Compact magnetic energy storage
- Cheaper MRI machines, maglev trains and fusion magnets
