    Today I decided to try using my solar sand battery to dry out stock I have for my kelly kettle. I put the semi moist wood in, and at end of the day I pulled out crispy dry kindling.

    With my tricks I have learned I was able to boil 6 cups of water in 5 and 1/2 minutes with the dry wood.

    I was wrong about how many solar panels I am using I have 3 240 watt panels hooked up to the single burner…. So at max 720 watts of power….

    So… At last my toy moves to being a dehydrator. I was using 5 panels before… I think because I had the nicrome wire part of the burner too insulated with sand that, and spilling sand on the burner is what killed it.

    Now I can dehydrate more things…

    I am getting like 6 hours of time at temps from 200 – 340 degrees F. Using 3 solar panels and 5 gallons of dry sand. Now, I believe I just need to improve insulation… I am thinking layers of cardboard around the outside should do the trick as I have an airgap between the trash can and the 55 gal barrel which is holding up well…
