Reused cans, solar "heat pump" (sort of)

That technology has been around for quite awhile-but I like the fact that this individual had the capital to make it a business.

I built one similar to that unit two years ago(soup cans as I don't drink soda, plywood box with a reclaimed window for the face, wrapped PVC pipe through a SIP window block and a leather 'hinge' for a one-way valve) and I have never regretted the $5 worth of high-temp gasket sealer nor the $10 block of SIP...paid for itself in savings in one month. In the summer, I run the heat feed into an all-purpose curing/dehydrating cabinet, and cure wood for walking sticks or make jerky-works a treat on bamboo fishing poles too!

Frankly,it astounds me that A) there is enough of a demand now that this innovator was able to start a business building these units, and B) that the people wise enough to buy these units aren't wise enough to manufacture their own for the cost of spare parts and elbow grease...the manufacture of Solar Thermal isn't exactly a Trade Secret, after all...

...true, but there are SOME people (who shall remain nameless) who don't know a hammer from a shoe heel, or a screwdriver from a butter knife, and have been known to donate more blood than an Ice-Hockey Player just while fumbling with the instructions (wink,wink)!

I happen to resemble all of the above...and I built one. Also, paint fills in a lot of heel marks, butter knife scratches and bloodstains!

I suppose some people still think that Labor=Money=Labor=Product (make money to pay someone to build it) makes more sense to some than Labor=Product (build one). I guess that's Economics for you-mind you, I wish the gentleman in that video all the best at filling that niche.
