Florida has been woefully slow about utilizing the vast amount of sunshine that beats down on our heads.
When I was a kid there were still a few of the old school rooftop water heaters in town but everything was going electric back then. There was a resurgence of them in the 80s with more modern panels and pumps, but that soon died out as electric and gas units were made more efficient.
I reckon they still sell em? It aint something anybody but Chunkstyle ever talks about.
Good coffee, good weed, and time on my hands...
