Solar "pop/beer" can heater

[Shark]

Sorry if this was already posted but I couldn't find anything so here it is once again.

Looks pretty easy to build, low cost, & would be a good supplement for cold weather heating.

It looks like this guy actually builds "nice" units & sells them:

But there are tones of other video's of home-built units that operate in the same fashion.

Yep, that's a cheap, easy way to provide supplemental heat. It's something I've been thinking about myself. Living in an RV though the winter is going to require a lot of energy, and I really don't want to pour money down the drain buying propane to heat this poorly insulated little box on wheels. Cans would help immensely. However, I do already have my solar thermal collectors for domestic hot water. I will probably use them for supplemental RV heating in the mean time. By adding a storage tank, I can extend the heating period. I figure I can just install a small radiator in the intake portion of the RV's heating ductwork.
