       | Fascinating. So by my dummy math, if you could get even 400 of
       | these toaster-size devices on Mars, in just over one year you
       | could produce enough oxygen to provide appropriate levels of
       | rocket-blast-off oxygen for a trip carrying four astronauts?
       | 
       | 6g / hour * 400 = 2400g/hour or 57,600g a day = 21 million grams
       | in an earth year.
       | 
       | 55,000 lbs. = 25 million grams about?
       | 
       | And you'd need about 1/25th that amount for those astronauts to
       | breathe for a year...
       | 
       | Just to say I'm curious to know how this technology could scale.
