    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...

    K, you are entirely correct. I currently use a 1500W internal heater to heat up the water when I purify the water in the water purifier. It makes no difference to the equipment as to where the electricity comes from. Last month when I went to Bonnaroo again, I took my 230W solar panel, 5 100Ah batteries, and my 5000W inverter to run my portable AC unit...it’s the same principle.
    When I have the extra positive cash flow, I plan on installing along with the solar panels, I plan on installing
    2 solar evacuated tube solar hot water heaters and a solar hot water tank. Again, same principal, just using Mother Nature to heat the water for me.
