I asked a question about using molecular sieves, solar power and thin

nitrogen and water 5,000x from Mar's atmosphere - to provide water,
oxygen and nitrogen - needed to sustain life on Mars. Each person
needs about 10 watts per day for this purpose - out of a budget of 165
watts per day.

One who can write "watts per day" is manifestly technically
incompetent. One who can write Mar's is manifestly ill-educated.

You don't grok. Grokking requires glial cells.

You think you can keep all this straight all the time?

Dude, that's why we invented wiki. To help keep it all straight.

Its not that I didn't get it straight, how could one forget that Joule/
sec = watts? Its that I mispoke, - a malpropism its called. And the
Mars' thing - is a simple typo.

The point is the '10 watts per day' should have been '864,000 joules
per day to provide the daily requirement of oxygen and water' and
the 165 watts per day should have read 14,256,000 joules per day total
energy budget.

Of course when you divide these daily rates by 86,400 seconds per day
you DO get a rate of power - 864,000 joules per day may be supplied by
an average power usage rate of 10 watts. 14,256,000 joules per day
may be provided by an average power usage rate of 165 watts.

The malpropism came not from any deep seated ignorance of the
difference between watts and joules - but what I was trying to
communicate. The power levels required to do ALL the things needed
to survive on Mars and the relative disparity of supplying oxygen and
water on Mars needed by a person each day, and the average power level
needed to supply those daily needs.

Watts per day - read as a stand-alone statement is confusing - its
either a rate of power growth, or a mistake. In the context of this
discussion it is a malpropism caused by the fact I'm looking at the
power requirements to sustain the physical needs for oxygen and water
each day on mars. 10 watts continuous supplies oxygen and water
needed by an adult male from the atmosphere of mars. This power level
allows the extraction of 909 grams of oxygen and 6.7 liters of water
each day from the martian atmosphere. Rather than write that I wrote
the malpropism which contracted it all - and left Stockton with the
wrong impression.

haha.. thing is I thought anyone who understood what was going on
would see the malpropism (and the typo) and understand what I was
getting at. I guess this just goes to show, some people are fools
regardless of badges.

Human life sustained on Mars for a mere 10 watts.h

Now that's even impressive for a true shut-in wizard like yourself.

Of course at 10 mb it's going to demand a great deal extra O2 than at
1 bar, not to mention the daunting task of keeping your biological
aspects reasonably ticking while more than half the time it's colder
than enough for making loads of dry ice, and otherwise it's nearly a
vacuum and irradiated enough to get rid of any cancer cells throughout
your entire body within the first few days, if not sooner.

And you seriously expect not having to pay folks big bucks for
attending your Mars expedition?
