looks pretty cool, but $3800 USD is not worth it IMHO, still cool though :-)

Agree, but if you had a group of like-minded people ……...

Geez sleepydude, that's very ambitious!! I remember a plane trip where we were served bagged fresh apples. I don't know how they were preserved, but they ad an unusual taste on them. Thanks for the link VegHead - very interesting.

I've often thought about getting a freeze drier, but there's no way I could justify the cost. As VegHead said, a group could make it worthwhile.

Big $$ item that's for sure, even if the food keeps as long as the commercially available stuff and you have the time to do large amounts it would be hard to justify the cost, especially compared to home canning. The value of the Aussie dollar doesn't help either. But, as mentioned, if you can get a few like minded people together it would be very cool to have

I've been experimenting with a few different lower tech/lower power ideas, such as giving food freezer burn on purpose and creating a lower pressure vacuum chamber and putting in the freezer without much success. It's a simple idea really, put food in a vacuum and the water evaporates/sublimates [https://en.wikipedia.org/wiki/Sublimation_%28phase_transition%29] out over time. I am still waiting on a vacuum sealer for mason jars, to which will be my next test, though I'm getting that 'mostly' for vacuum sealing of dry goods, to which it will be useful and the benefits are known. Not only is it the cost of the unit, it's also the cost of running and how would you run it in an austere environment and I would think that the sums would suggest just buying the commercial freeze dried goods at twice the cost it takes you to make it. Aka, it would take a lot or freeze dried goods to make buying a unit worth it.
As already mentioned, dehydration works pretty well, is cheap, easy. Canning obviously too is an option.
