How do you water cool a steel plate under a rocket without the coolant instantly vaporizing and blowing up the plate?

> instantly vaporizing and blowing up the plate

It sounds like you are thinking about the water coolant being in or behind the steel plate.

But if you pump water on top of the steel plate there it can instantly vaporize without blowing up anything. If you have sufficient flow then that can keep the steel plate from melting.

They’ll need pumps bigger than the rocket’s fuel pumps.

Nah, just some water towers. You can fill the water towers slowly using small pumps, then drain them quick using gravity.

In the Spaces thing, he described it as being like an upside-down shower head, and to expect lots of steam billowing out during launch instead of dust, so I don't think it's a closed system.

4.16 mega litres a minute.

Must be some fair old pumps on that setup!
