TIL: the Perseverance mission is field testing a system for electrolysis of CO_2 to O_2 on Mars' surface, for possible use for in human life support.

The goal of the MOXIE subsystem is to demonstrate 10 to 22g of O_2 production per hour at 300W power consumption -- half what one single human needs. If this works, the CO_2 in the air is free and wouldn't need to be recycled in place, whereas all the water we still need will definitely need some level of recycling.

@progo so 600w of power per hour, per person. Then how ever long the nights are on Mars. Plus some cleaning system to keep panels at peak production.

@ralphw
There is no such thing as 600W per hour. I clearly said 600W per person.

@ralphw
Also it's a tech demo. Actual human village scale may have lower power requirements per person.

@progo 600w per hour is exactly what it would be. Written another way, 600 watt/hours. On earth, such a load would be 600w x 24 hours = 14.4kwh per day. My 800w array makes around 4kwh per day.

@ralphw 600 watthours is 600 watthours. "600 watts per hour" is NOT ACCEPTABLE LANGUAGE.

@ralphw 1 W == 1 Joule per 1 second.

The only time it makes sense to write "Watts / time" or "Watts per time" or anything like that is if you are ramping a generator up or down.

If I read "watts per hour" in any other context I get triggered and I can't see past the illiteracy.
