What on earth do you need 20 kilowatts continuous for? That's a huge amount of power for domestic use.

What on earth do you need 20 kilowatts continuous for? That's a huge amount of power for domestic use.
- throwanem 6y agoTypical US domestic service is 24kW (120V/200A nominal at the main breaker).
- dTal 6y agoFair enough. Still, it's one thing to be specced for 24kW peak load (the breaker) and quite another to require 20kW continuous (two 10kW nuclear power plants). I still think 20kW is an awfully huge amount of power - the average US house only uses about 1 kilowatt when you smooth it out.
- User23 6y agoWhat on earth do you need more than 640k of memory for? That's a huge amount of memory for domestic use. Nobody knows what kind of innovations a huge readily available sustainable energy supply would allow, but I bet they'd be cool.

- xyzzyz 6y agoHow can you use electricity to cool things in space?
- andruby 6y agoPiezo-electric? But then you need to cool the other side even more..
- sandworm101 6y agoYou run a pump on a coolant loop, just like any air conditioner.
- sandworm101 6y agoSame as in a car or any air conditioner. You pump a hot fluid to/from radiators. Look at the iss. See the big black structures always held perpendicular to the solar panels. Those are the radiators. https://en.wikipedia.org/wiki/External_Active_Thermal_Control_System https://en.wikipedia.org/wiki/External_Active_Thermal_Contro...
