Pressure cooker still

Dome,

How large of a mirror, or mirrors, do you think you'd need for Precious to become a solar powered still?

Well K, I’m not sure if you are serious, but a solar cooker uses 4 reflective mirrors to boil water, so I’m guessing would do the same with an 8 gallon stainless steel milk container. Don’t know how long it would take to heat up to 200 deg. Maintaining the temp would hard to do.

Yeah was thinking that same thought... Fine control and duration of heat appears to be the key. But I do recall, before the big ethanol boom/bust years ago some Iowa farmers were getting fined all to be damn for using solar stills and their several plant materials to brew up methanol for running their small engines.

I'm not being a green weenie, but rather a cheapskate. If a big enough bank of solar charged batteries can run heating elements sufficient to cook your mash...
