According to Autocar, Tesla will be rolling out 1 MW chargers for their Semi and intend to apply it to the Cybertruck as well:
"The upcoming Tesla Cybertruck SUV will get the same 1MW (1000 kW) charging speed as the Tesla Semi, founder Elon Musk has confirmed.
The firm claims the Semi has the ability to replenish 70% of its 1000-volt, 1000kWh battery in just 30 minutes. Although no battery size has been revealed for the Cybertruck, this could mean a full-charge time in just a number of minutes.
The charging speeds, which will be the fastest ever available to the public, will be rolled out across Tesla's supercharger network in the US next year, Musk said. It is expected to come to the UK with the launch of the Cybertruck next year."
That'll dim the neighbours' lights a bit!
I'm wondering about cable size etc.....it could be like wrestling a python!

I think there is a "Tesla factor" to apply to this.
1MW being 1,000V @ 1,000A.
A 1,000V battery will need over 1,000V once it's passed about 50% SoC. And at low SoC the charger voltage will be lower and therefore the current even higher to reach 1MW.
The problem is I'm pretty sure existing superchargers can't get over about 500V DC so they may well need new hardware.
As usual with Tesla, no actual specs released just some impressive sounding numbers.

Tesla's approach to charging is to push as much power as quickly as possible, often having quite steady declining or stepped charge curves (but still maintaining a high average rate over the period).
So I expect you'll only see 1MW in the sweet spot (typically around 40% SOC on Tesla according to FastNed), but the average rate will likely still be in the realms of several hundred kW.

Liquid cooling of computers was done back in 1985 with the Cray 2 so cooling a cable with similar stuff sounds plausible

Liquid cooled cables are already in use. https://en.wikipedia.org/wiki/Cray-2

But that’s obvious / a given.No semi is ever going to get in to / access the likes of a supercharger for cars
The CyberTruck will ride off the back of this rol out (on the basis that a) they are huge, and b) CyberTruck are likely to be used / drag stuff around as a mini-rig
