I've seen a few posts where folks are discussing their ideas for water and heat/insulation.
I, too, am experimenting: I want to make a solar heater with a panel of aluminum cans painted black under plexiglass, with the insulated conduit running from the top of the panel into the coop, coiling through a box of sand for a heatsink, and then back out into the bottom of the solar panel. Waterers would sit on the sealed box of sand.
Am I nuts? Look at how well these panels can work: http://www.treehugger.com/files/2007/04/pop_can_solar_p.php
LOVE this idea! Was even considering having the return stretch be made out of copper and done in a flat coil to express as much remaining heat as possible before entering the panel again, so the coop would be heated from that loss...
