If an output rate of 1 to 2 gallons per day is too small to specify, I'm happy to run a 1 gallon per hour water maker for only 1 to 2 hours per day -- provided it doesn't cost thousands of dollars.
1 to 2 gallons per day is my actual usage now, so I don't want to spend $3,000 to $5,000 for a 1 gallon per hour watermaker
-- unless I have 23 crewmates aboard (which is impossible on my 26 foot boat). When crewing
on other boats, I am astounded at the gluttonous water wastage. I suppose that's why there's such a large market for high output water makers. Using more than 1 gallon for bathing would get you kicked off a submarine (where those kinds of wasteful baths are called a "Hollywood Shower" requiring special permission). In temperate climates, I can't drink and cook with more than 1 gallon per day. I avoid foods that require boiling.
I'll appreciate any links to DIY
I recently retired from NASA. They allocated 2 liters (~ 2 quarts) per day to each astronaut for bathing on ISS. For bathing aboard I use what I call a modified ISS bath:
1) Add 1 cup (250 ml) of water to a ceramic bowl. Add a little liquid soap and a hand towel.
2) Heat in microwave for comfort (about 1 minute - 2 amp/hours consumption
from the 12 volt battery
3) Wash body.
4) Empty bowl.
5) Rinse hand towel in 1 cup of water.
6) Empty bowl.
7) Add 1 cup of water to bowl.
8) Heat in microwave for 1 minute.
9) Rinse body.
10) Rinse hand towel with 1 cup of water. Hang to dry.
So that's 4 cups of water (~ 1 liter) and 4 amp/hours off the batteries
for a "bath."
I shave with an electric
shaver (recharged from the battery
bank - maybe 0.1 amp/hour per day, max.). All power is generated by sunlight and a towed impeller generator
clothes: In warm weather
, I wear cheap
all-cotton hospital scrubs (with no synthetics) for a few days each and then toss them overboard
and biodegradable), or I put clothes in a fishnet, drag them overboard
, and hang up to dry. If I'm lucky, they get rained on while hanging. Residual salt
residue is minimal.
I wouldn't know what to do with 24 gallons of water per day, let alone where to store it all.
