re: #420 prairiefire

Ok, Obdi, I just measured the water I would realistically use. You can do the math, I’m math challenged. 2 cups or almost 1/2 a liter. Add another 6 ounces because I have the habit of rinsing out my mug at work to get the dust out. So 22 ounces a day, for 47 weeks?

I am not Obdi, but that’s half a ton of water (452.375 lbs) a year.

Now, we also need to consider: the energy need to pump that water, the energy need to warm that water (water is expensive to warm), the energy needed to produce the soap each day…

It’s not simple, in part because we all neglect the second paragraph most of the time (and I am included here).
