Blog Hemmings: voitures classiques et de collection et des pièces
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. For that reason, I never hooked up the first one – in fact, I gave it away to a friend – and set about building a bigger, better version, suffering through three cold winters in the garage. I started out by looking for a sliding glass door, which I found locally for free, then took all my measurements from that. Recall that the first version pushed out a paltry 15 degree temperature differential.
