If you are looking for a way to lower your heating bill this year you probably want to look into this Pop Can Solar Heater idea. It is quite simple and is nice since much of the contents of the system is recycled. " The Cansolair Solar Max 240 consists of a four by seven solar collector (28 Square feet, or 2.6 square meters). Solar Max 240 has 15 vertical columns of cylindrical shape, making the actual surface exposed to the sun greater than 2.6 square meters.The same cylindrical shape allows the Solar Max to receive solar radiation for a longer period due to the angle of incidence of the sun hitting the solar panel. Peak BTU performance was observed during the noon hour period in October 2001 wherein the temp rise was 50 to 54F degrees resulting in a 9000 to 9720 Btu or 2636 to 2847 Watts. Peak BTU performance will actually increase in colder weather due to the rise in temperature between input and output temperature and a lower angle of incidence. The Solar Max 240 has a quick response rate of 8 minutes from the appearance of sun to “cut-in” based on 100 degree F output temperature. Solar Max 240 uses the most conductive black paint available for solar collectors. Solar Max uses a lexan outer cover which allows sunlight in and is resistant to the elements."

Wow! Cool gadget!! Pop can, huh…

well this article shows how technology is going to the next level. Kudos to the fastest techs

I like the idea, but do not need the heat in the daytime as much as I need it at night. What about heating oil (olive oil, perhaps?) with the sun, and then circulating the air over the olive oil. The olive oil will hold the heat from the sun longer than the air.

Really? 100 cubic feet per minute? My computer moves more than that.
What a great idea… if you live someplace cold, but heating is easy, it’s cooling that’s hard

I’m surprised that this is the first time you guys have looked at this, he’s had this company going for at least 4 or 5 years now and even then it was relatively big news because the provincial governments were helping him. However, there is a couple flaws in the design, first and foremost being that lexan does yellow and therefore will lose the heating capacity of the unit, next is that he has nothing in there to keep the system from reversing at night. Also, how long would it take for you to put holes in approximately 400 cans and then tig weld them all together? Yes, novel idea, but…there has to be a more efficient way of doing it.

One issue to easily overcome is that most cans have a coating on the inside. I wonder how many of them have coatings containing Bisphenol A. Like estrogen, in very small quantities it causes massive changes in gene expression in the human body. When will the scumbag corporate controlled U.S. EPA ban it??!! I would search for cans without such interior coatings and let them burn off in hot sun for many days before I pipe them into your house.
You could make just as effective a unit using aluminum foil kitchen/food wrap. Then you only have to heat the paint to stability in the hot sun. Again a week or so should be enough. In any case let the paint dry without the lens in place , for about a week or so. When paint dries it release harmful volatile organic compounds,, so let the stuff dry well, then let it cook for a week with lens in place before you pipe it into your house.

Daniel,lexan is uv stabilized,will not yellow for very long time.Also to keep from reversing at night it has double check valves http://cansolair.com/features.htm .Its 240 cans,holes are easy,cans are glued together w/caulk,not tig weld. just my 2-cents;
