Good luck!
you've got more in you but quality not quantity! Your video of how to construct a swamp cooler is pretty interesting and hoping that you'll show more of how it actually "works" ... as well as maybe some comments on what off-grid life the "mild desert" would be like without it. Would it be conceivable for you to equip your bigger structure with a similar setup or not?
Unfortunately...the amount of water needed to provide cooling goes up exponentially as the size of the space you need to cool increases. Depending on the size of a commercially available swamp cooler, they begin at using about 3 gallons per hour and go up from there. Large swamp coolers use as much as 20 gallons per hour. Pepino is barely big enough even for my 128 sq ft hut but only uses about 7 gallons of water per day. It is perfect for days when the high temperature is up to 95° - but when it is over 100° it can't really keep up. During the hottest part of the late afternoon (in July) I use my AC for about an hour to take the edge off. What Pepino is most useful for is cooling down the hut after dark and overnight so I have a comfortable sleeping temperature.
Just for comparison - over the course of a cooling season, Pepino uses about 1,300 gallons of water (182 days x 12 hours per day x 7 gallons PER DAY = 1,274 gallons). A small commercial unit running for the same number of days and hours but using 3 gallons PER HOUR would require 6,552 gallons of water per cooling season.
Trying to think back on how much water you can accumulate in a year.. 6552 would probably put a substantial dent in it if not outright very difficult.
My total storage capacity is 22,000 gallons.
Do you get summer storms there? I wonder what months if any, can provide a predictable amount of rain, to budget.
Our "rainy season" is June - October.
John will the next 2018 Field Lab T Shirt be a 'Bucket' silk screen print one?
Huge apologies John. I realise I may be totally out of context here and that my comments have no revelance at all with the current topic at hand. This was just a thought....
