Mechanical Transmission of Power: Endless Rope Drives

You don't need electricity to send or receive power quickly.

In the second half of the nineteenth century, we commonly used fast-moving ropes.

These wire rope transmissions were more efficient than electricity for distances up to 5 kilometres.

Even today, a nineteenth-century rope drive would be more efficient than electricity over relatively short distances.

If we used modern materials for making ropes and pulleys, we could further improve this forgotten method.
