Freeze drying is the process most of the long term storage food uses. Home units cost In the $3500.00 range, but I think I can make my own. The food is frozen first, then a vacuum is applied for 10 to 12 hours. The vacuum reduces the boiling point below freezing, and the water outgasses through the pump; leaving the food dry, and in the original configuration.
I just can't justify the the expense, especially if I can make it myself. The commercial pressure cooker I already have will make a good vacuum enclosure!
They say freeze dried will last 25 years if kept dry. I have some 2 quart canning jars that should work for that!
I want to have 3 years of food stored, and tgen live off of my produce. That way, if I have a bad year, we are safe. When we have a good year, we can restock the supply.
Thr wallipini (buried greenhouse) here should produce food year round, without added heat.
I want to build one of these wallipini things. so many projects and so little time. Considering I have an average of only 106 frost free days in a row, I think they should be utilized more in my region.
I intend to run a long piece of 6 in tubing below the frost line, by circulating air through the tube I can draw ground heat into the walipini. Here that means I can probably grow plants year-round without added Heat, in your area it might give you six months. Adding additional Heat, could further increase this time for you.
The long tube below the frost line, is called an earth battery; it is used to both heat and cool. With the base of the walipini Underground, and the north side of the walipini being bermed with the removed dirt, you draw a lot of the earth temperature without using the Earth battery. With a big wall on the north side, with dirt behind it; you have good support structure for columns going down to the ground on the Southside. These columns can support the glazing for the greenhouse itself!
Then you plant like you know what you're doing, LOL!
Sorry, chronic reading and rain rot, LOL! I've been studying alternate energy since 1980, so I picked up a thing or two.
I'm going to use the Earth battery on my walipini to heat and cool it. They are circulating through that tube will hold about 59 degrees if it's deep enough. Locally 18 in is enough I intend to go down about 3 ft. Where you are it would have to go deeper, wheee that numberis for you I'm not sure exactly where you are. I know it would be below the frost line where you run your water lines, so I'd put it a foot deeper than your waterlines are normally buried.
They use earth batteries in Arizona on the earthships for air conditioning. So it works either way.
YES! Same sort of thing as a heat pump. The idea is to get 60 F temps to the surface and that works great for cooling and is easy to heat to comfortable room temp in the winter.
Apparently, we need to go down 8 feet for this earth battery to work for us. My husband just said that he would go down 10 to 15 ft because when we get a bad winter the frost goes very deep.
This is exciting! I have given my husband so many new tasks since I met you! :-P

♡♡♡♡Sounds fun. How long term are you hoping to keep your food?

♡♡♡♡Wow! Exciting! I have heard of a heat pump but not an earth battery. You have a lot of interesting knowledge.
