"They typically had a steel casing, copper for conducting power down them and optical fibres for collecting data, " he said.
To make the light travel enormous distances, thousands of volts of electricity are sent through the cable's copper sleeve to power repeaters, each the size and roughly the shape of a bluefin tuna.
The real advantage is that the lack of resistance means that a given thickness of superconducting cable can carry between two and ten times as much power as the same thickness of copper.
And if those copper wires were replaced with something better, even more power could be piped through the grid.
Think about that as your hybrid runs stealthily on battery power, brought to motion by the conductivity of copper.
In cyclical sectors like steel, coal, copper, or even aerospace and oil I can model average earning power over a full cycle or even use a discount table on assets in the ground.
