Hello All,
Ironic that FrankG just posted some awesome pics using the cans. Here in Michigan we have a 'deposit' law so they'd cost 10 cents a piece....acceptable. Anyway, back to the ironic part. I just finished a small one 24" accross by 6 feet tall to supplement my four season room. It was based on a design by someone here I think, or maybe Homepower...using a double layer of black screen suspended in the middle of a 2 x 4 frame, plastic greenhouse glazing, holes at top and bottom, simple convection....The whole thing was made from scrap/odds&ends taking up space. Thought I could improve it abit...used polystyrene 1" for the back and then "spray-mented" tinfoil over that to capture the relected energy. I set it up this morning and ran some errands. Normally the room would be about 70 degrees F, but when I got home about two hours later (11:30 am) we were at a balmy 85! Yahoo! NOT!
Unfortuneatly, either some exposed polystyrene or the glue for the foil were giving off some potent gases/fumes. Had to take it outside to let it breathe out so to speak. Almost forgot, it's been about 60 F all day...I'll try again tomorrow after it's been aired out....
