\"soda<\/a><\/p>\n

We’re finally cooling off after a brutal Summer here in St. Louis. While I’m thoroughly enjoying the temperatures in the 60s and 70s, they’re a good reminder that Winter will be here soon, and that we’ll be paying to heat the home<\/a>.<\/p>\n

That got me thinking about a concept I first encountered a couple of years ago: the soda can solar heater<\/a>. Very similar in design to Gary Reysa’s\u00a0thermosiphon air collector<\/a>, this concept uses aluminum cans to build columns that collect and transfer heat from the sun. While I’ve come across a number of variations on the concept, most tinkerers who’ve tried this project point to Rich Allen’s video walk-through of building one of these heaters as their starting point.<\/p>\n
