Re: Engineers harvest clean, continuous energy from air
#2The paper says a cubic meter of the material could generate more than a kilowatt (per hour?)... sounds promising if it actually gets commercialized.
I assume it would only work well in places where there are significant humidity swings, I didn't read the paper very carefully though.

#3News releases like this are always optimistic, but there always some hidden cost they don't tell us about.

> more than a kilowatt (per hour?)
Not sure what you mean, Watt already has a unit of time in it.

Nope.

And now it's your job to figure that out!

#8Despite being a chemist, I don’t fully follow this, though it seems legitimate.
But if there’s that much latent energy, I really have to think that there could be some kind of atmospheric, “local ecological” side effect on microorganisms or “something” at scale. It’s not like nature lets massive amounts of energy go completely unused.

#9We really need an "absurd level of clickbait" button on HN, to burry such headlines.

Nope.
Watts are a rate of one joule per second.
If you want to talk about a quantity of energy rather than a rate of energy production/consumption, the units would be either kilowatt hours or joules (1 kWh = 3,600,000 joules).
