Nice, I like it. You want to think about a way to close it off in the summer and if you can put a small fan in there it should do better. You can buy a small DC voltage regulator board on ebay and vary the fan speed.
so are you saying that this design produces more heat then the pop can design? I am looking for the most efficient one befor I build. Would love your input!
How do you plan to shut off the vents to prevent cold air from coming in at night? I have a powered one but I have to manually block the holes at night to prevent the cold air from coming in.
During the might in winter those open holes will act as cold air conduits with no cover on them. Any test on how hot the air is during the day in the winter? Also did you consider the path of the sun before the installation as the idea depends upon sunlight entering the box? And lastly what about insulating the box to prevent heat loss during the winter? Touch a window pane during the winter and see how cold it is and that would draw heat out of the box.
The only way this would be beneficial is if the air was compressed much like a Heat pump other wise as others have mentioned, if its -20 out your not going to get 120 degree air on a empty box with aluminum roofing as a heat exchanger!
Nice, warm project! I used beer and pop cans in my first solar house heater which measured 3 foot by 5 foot with a heat output of 55 C. For my second solar heater I used aluminum down spouts which was way faster. It measured 3 foot by 6 foot with a heat output of 140 F (60 C). So I scaled it up to 6 foot by 6 foot and it has a heat output of 203 F (95 C). They work great adding free heat to my house every sunny day! ua-cam.com/video/7S8CWsIcK20/v-deo.html
this was in 2012 using a pocket shooter camera with video clip ability. he is hand holding it. he is not a videographer. Absorb the knowledge be thankful.
Nice set up, thank for sharing this information.

*SOOORRRIIEE*
this shows how easy it is to make a heat panel and be enogh energy wise. good job!
you are the only person I know who can hold something over 140 degrees and not burn your fingers
Good easy build with passive heat - good job!
Incredible invention..thanks for sharing...!

The Solar Air Heaters look great and inexpensive; but, do you lose heat through them during the night or non-sunny days?
what kinda heat would you get when its minus 20? just wondering
nice idea!
is this solar heater still working today? does it have the same result since the first time you use it?
Hi, I'm looking at making a solar hot air box and I need your expertise advice, would using onduline bitumen corrugated sheeting be OK to use?

Just a drywall mudding tip, make it as smooth as possible and sand less, layers not to thick, drywall mud shrinks alot when drying

You cold connect the ventilator to a small solar panel.
No sun, no air.
You need to use a single piece of glass for a solar heater, Insulated units are a thermal brake, they are made to block out heat
Holds heat in. I don’t think the sun knows there’s two panes of glass.

I was hoping you had a thermometer in the bottom hole 2
much better without cans

Get a 50 W solar panel and. a 12 vdc fan.
They only work in day light : (
duh
What is it with you video makers and the constant moving of the camera? Focus on one thing and leave it for more than a second. Jeez
