Soda Can Solar Heater, v2, Completed
I’ve had plenty of people asking me lately what’s going on with Project HMX, and unfortunately, progress on it has stalled for a number of reasons. Chief among them are the other projects that have taken time away or quite literally blocked me from getting to the HMX. Over the weekend, I got one of those projects out of the way. Ever since I built my first soda can solar heater three years ago, I’ve received plenty of input on how to improve the design for better heat output. Aside from the addition of the insulation, the build went pretty much the same as the last one: Build box, seal it up, drill holes in cans, stack them, paint them, drill inlet and outlet, use shop-vac parts to funnel air in and out. Recall that the first version pushed out a paltry 15 degree temperature differential. Thanks to everybody who offered input over the last three years, and please continue sharing your own soda can solar heat projects!
