On: NASA can now reliably produce a tree’s worth of oxygen on Mars

[secondcoming]

'A tree'... what's that in Olympic-Sized Swimming Pools?

[spywaregorilla → secondcoming]

A tree's production capacity seems like a very natural unit of measurement for oxygen production to me?

[Arnavion → spywaregorilla]

Different trees produce oxygen at different rates, due to difference in size and difference in species. Also even knowing about one standard tree doesn't tell you how many people it would support, for example.

[Tade0 → spywaregorilla]

Which tree specifically and what age?

[spywaregorilla → Tade0]

If you have the capacity to use that information, you also have the capacity to understand the ballpark of what is meant by "a typical tree".

[pessimizer → spywaregorilla]

And if you don't, you don't, and a comparison to something that you understand would be better. Give me man-minutes.

[spywaregorilla → pessimizer]

Man minutes in a suit with controlled oxygen? Man minutes in a cockpit? Man minutes in open atmosphere? A bunker? A ship? Large man? Woman? Obese man vs fit? Golly this is as poorly defined as the tree problem isn't it.

[Tade0 → spywaregorilla]

Actually, no, because the variance is so high that the "ballpark" is meaningless.

[spywaregorilla → Tade0]

Seems like a pointless appeal to non cognizance to me.

Show me the distribution and I'll show you the median.

Are you suggesting trees migrate?

[spywaregorilla → InCityDreams]

No?
