I got the idea from this newsgroup something like a decade or so ago.
You'll never need toilet paper ever again and you'll be cleaner as a result. During Covid, I was wondering why anyone hoarded TP in the first place.
How does Covid make you need more TP?
Good point of view, where I live alone but it doesn't touch the body.
How did you know?
I used to use this but it was just too difficult to keep clean.
Three of these a night tend to be simpler and work better on your side while in bed, with one more kept by the office computer because it's emptied more easily into the five gallon containment bucket (which is a re-used Costco 40 pound jug of soybean oil, or whatever size it is).
For the environment, I collect the thicker stuff in one of these.
It feels good to give back to the soil, where I combine kitchen scraps, wood chips, and humanure in layers in a re-used Costco dichlor bucket with the cap held tightly as the bigger corvids fly around where I've kept it, I guess they're thinking a dead animal lives there or something. :)
I don't think I waste anything as I burn all paper in the fireplace along with the wood in the wood-burning stove, so it's only plastic that I have to place in the recycling bins about once every two months per bucket.
I'm not disagreeing with you as I said I didn't know from the start. I do know pool chemistry though - but not battery chemistry. At least not yet. But keep talking and I can learn from you which is a good thing.
I don't think I've had to add water to a car battery in years. I guess it's done though as the caps come off (two sets of three).
You got me there.
The pool chemistry is simple because pH doesn't matter for sanitation where I just pour liquid chlorine into the pool to maintain the chlorine level at least 7.5% of the cyanuric acid level. That's it for sanitation.
For saturation, there are a half dozen factors, only half of which do you have any amount of control over, the other half (like temperature) are out of your hands so it's a game of matching the saturation index with the expected temperatures combined with the dilution when it rains and the concentration when it evaporates and you have to fill with city water.
I would think battery chemistry has the same "type" of equilibrium constants (Pka is what we deal with in pool chemistry) though.
Just different chemicals and more redox stuff.
