From seawater to drinking water, with the push of a button

I think part of the confusion is we don’t normally have units for rates of change.

So let’s create one: the “walk” is the speed a person can walk — 3mph.

Then I can say the store is “3 walk-hours away”, even if I normally drive the 9 miles with my car.

3 walk-hours = 3 hours @ 1 walk = 18 minutes @ 10 walk (or 30mph)

Batteries are rated in “watt-hours” for the same reason:

3wH = 3 hours @ 1 watt = 18 minutes @ 10 watt

Then I’d say you walked 1.5 miles in 30 minutes. The equivalent to saying generated 15 watts of power over 30 minutes from a panel that’s providing 30wh of power.

I’m assuming what I’m saying is wrong, I just can’t spot it. Thanks for the help.
