$1 portable, collapsible solar hot water collector
Making hot water using unmodified trash bags (which were later used for their intended purpose). You can’t beat the ROI on these DIY solar collectors. In cold, cloudy or windy climates, an additional layer of plastic can be put over the top to hold the heat in like a greenhouse. Some day I will replace these with an inclined box and a toilet valve filler, complete with shower head.

@gazzat5 These worked well even in the cool Alaska summer. I took luxurious hot baths without worrying about the heating bill. I was going to replace these with a rigid, insulated collection box angled toward the sun, but I spent the winter in a nice, warm place where it was not necessary. A heater core would probably not work because it is too small of a collection area for the cost.

genius! How well did it work?
I’m thinking about the uses of a heater core from a car, they’re available on ebay for pretty cheap or probably junk yards.
