Nit: I believe you meant 500W. 500wHrs would only keep the air breathable for an hour. Doesn't change your conclusion though!

- ChuckMcM 10y agoYou are correct, 500W for 1 hour (.5kWh) would completely counter the breathing of one crew member for that 1 hour.
- CalRobert 10y agoA rule of thumb for remembering whether you want to say "power" or "energy". If you could replace "power" with "horsepower", you're on the right track! If you could say "gallons of gas" instead of "power", you mean energy! wHrs is energy (and kind of a dumb unit. Watts is already joules per second, so you're saying (joules/second)*hours. It would make more sense to just say joules.
