What kind of wires do you need to handle that power?

The cable is cooled by a mix of water and glycol, which runs through the cable and also cools the connector pins. Tesla use this in their supercharger cables, as without it the cable would be too heavy.

At 1000V, 1000A require 0.13cm wire diameter[0] over 2 Meter with 5V voltage drop, just 15 AWG.

A 5V drop at 1000 Amps also means 5000 Watts of heat generated, you probably want something with less of a drop.

There will be free hot showers, electrically heated Brazilian-style.

Yeah that turns the cable into a 5kW space heater.
