THIS IS A 64 CAN , MY FIRST TRY AT MAKING ONE SO I MADE A VIDEO OF IT

@0urGaia Only thing is about co2 is that it could all be bullshit and co2 might do nothing different other than plain old air. I was thinking about car exhaust though….and my other thought was how much heat soil retained…the unit might be heavy as hell…but what if the cans or whatever held soil?…maybe even aspault coating the metal..
@magicyte think CO2 is very clever idea. I am not terribly educated in such things but guessing the heat loss is from black body radiation from the cans not from the heated air within the box.. If so perhaps laying 1 inch wide aluminum foil strips couple inches above the deepest line of curvature of the cans might help reflect some of that reflected IR back down at cans instead escaping through the glass.
@magicyte But after concideration…who really cares about a boost of R1 to the glass…whoopie. I wonder if there’s a reflection material that can coat glass on one side that will reflect heat…yet still allow the original visible light through.
@0urGaia For sure…but I’m fairly satisfied with the amount of energy we can absorb right now…it’s pretty damn good. I’d say our biggest problem is the glass. I’m building mine double pane…but even then it’s losing a ton of heat…besides going triple pane I don’t really know what else we can do. I was thinking of filling the glass with co2 though…
@magicyte, black reduces reflection visible light not IR. If we could get our hands on military energy absorbing stealth paint then we’d be cooking.
@0urGaia True…except when aluminum is painted/powder coated black that makes up for that factor. Too bad copper is just too expensive…black copper would be amazing.
@magicyte, but aluminum is is also good reflector of IR which is why its used building industry as an insulator, no? Much too poor for diamonds, guess have to wait for IBMs newly discovered tungstan film which has dendrites that absorb and trap 96% of the energy it receives.
@0urGaia Steel has a lower thermal conductivity than aluminum. simple fact. Btw..if you want more heat you go the copper route…and if you’re rich…try gold…or even better…diamonds.
@minh2817 no heat at night
Gread video, I will build one for next winter,
Dose it heat up in night time?
Thank you
That’s really great! Well done, I enjoyed your commentry and know how, thankyou.
Nice work,but i believe it more effective if you matched airflow through the unit with the port sizes. That is to say, if you need three can diameters to match the diameter of the inlet/outlet, then place 3 cans in parallel throughout the unit and have a channelling effect so that there are only 3 long channels flowing through the box from inlet to outlet. air is then being heated for a longer distance,absorbs more heat &there will be no restrictions in the air flow if the ports match the ducts

Great job! Where are you located – what state? Far North or Far South? What latitude?
Thanks.
Think making solar heater out of aluminum cans is not such a good idea. Rays from sun reach us at different frequencies which aluminum doesn’t absorb very well. I use to sit on steel plate in park during work breaks which was very hot even on cold cloudy days. So mine will be made of scavenged steel plates or pipes.

could you duct tape them handley?
I see from a TV program about the Solar system, The Sun puts about a 1 Kw of energy per square metre of the earth surface.
So should make it easy to calculate how much heat you can expect.
I like your ideal. Can someone make this one & show it on youtube?
I close my windows up in the winter anyway & it looks like I’m living in a cave till spring. Can you give more info?
Thanks.
Easier way.. get a sheet of Insulfoam from Home Depot. Measure you window and make a box out of the foam ONLY. Paint the inside black and cans. Put a ledge across the bottom. Make hole along top and bottom. Insert a small computer fan run by solar charger. Then place this unit into the windows from the INSIDE of the house. It is very lightweight and can be taken down when summer returns. Produces 120-150F heat.
Here in the UK we can get a Flue seal Silicone that can withstand 300′c
how much heat does it generate in winter?
cool ideal if you covered the whole thing with cans would help even on cloudy days temps run about 20 degrees higher on heaters please post vid if you make it rich
hi if i was going to glue them together would use the gutter glue the mortar does start to flake have you watched my loose can heater? works just as good and less work
Hey, I am very motivated by your video. Thank you for putting it here for us. I would like to ask if the High Heat Mortar that you used is performing well. You added that Aluminum Gutter Glue works well too.
My boyfriend and I are excited to build one following your pattern, but he wondered if the glue was made for masonry and would be flexible enough after it cured and was put into use. Thanks again for your video!
