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

Gread video, I will build one for next winter,
Dose it heat up in night time?
Thank you

@minh2817 no heat at night

@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.

@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 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, 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 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 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.
