Forced Air Heater Solar PART 3 Passive Heating HOW TO Use Sunlight Power Wooden Frame

PART 3 DiY Wooden Frame. This is a simple alternative to the soda pop can solar furnace. Simply placing a black backer behind glass with a very thin air gap allows for maximum air mixture. In later videos we will testing some 12v blower fans for different CU volume.

    I live in colorado — I can’t imagine, on a cold snowy day, that this thing would be very effective. I know my car certainly doesn’t warm up like your car did here — not when it’s zero degrees outside.

    careful… that looked like a FEMA helicopter. A prepper GREEN guy… like yourself could be considered a target for Obama’s boys. LOL

    Is the use of spray can paint bad for the ozone?

  4. lfvfd421 says:

    I could be wrong, but wouldnt it heat up alot faster and provide better heat if there was some sort of solid metal in the chamber? Like maybe a section of tin?

    @lefty0mtl You know you love the way paint smells, and tastes. And if Paint isn’t your thing.. you could use a giant Sharpee on it :P Jokes

    1000 watts equivalent are very nice, because I live in Europe we have to buld stuff like that.. energy prises here are skyhigh.
    1KW is 30 dollarcent
    1 litre of carburant is 1 dollar
    1 litre of gasoline for the car 1,45 euro 1,8 ; 2 dollars depending on the value…..

  7. 215alessio says:

    @lefty0mtl I have the same questions, because the air flows on alot of painted surface that is baking in the sun.
    I guess it will be unhealty…
    I think the sodacan’s is a more healty way because the inside is very clean and the paint never gets in touch with the flowing air (or very minimal inexisting touch)

    WOW !!!! That black mass of steel wool reminds me of my ex-wifes back! Reason # 753 why she’s my ex- wife.
    But seriously,does this work in a cold cloudy climate during winter. where yeti ex-wives roam the hills howling at the wind looking for more credit cards?

    haha… overspray on the lens

    @lefty0mtl sorry but where is denise??

    A quick suggestion… A friend of mine took an old refrigerator, painted it black, put the interior tank of a water heater in it, also painted black, and made a solar water heater out of it. I think he also put some sheet metal or a mirror in the back to reflect some of the light to the back of water heater. His first model used a single pane of glass as your construction on the solar forced air heater uses. His water got pretty hot. Model 2 used a double pane sliding glass door = much more heat

    Im curious to know how much heat could be brought into a house if you simply cut plywood panels more or less the same size as your house windows and hung these panels inside the house in front of the windows, maybe from decorative chains from the ceiling. The backs of the panels could be painted white to reflect heat in the summer if you just turned the panels around with the white side facing out.. Sure they would be ugly but curious if I would get the same heat output..

    In a future design, I imagine adding some thermal mass that would bake inside the glass frames would be able to store energy above and beyond what is being transferred in the air. A thermostat that runs the blower intermittently rather than all the time would regulate the temperatures too.

    Basicaly it`s just basic, you get the Basic idea though..

  16. astrialkil says:

    Could you put one of these up on the side of a trailer house and just paint the metal black rather then using the plywood?
    Do you need the heavy thermal mass of the plywood or would light metal work?


    @lefty0mtl Acrylic paint is inert after 2 weeks of open sun exposure. The smell goes away. If you are concerned (understandable) You could place a sheet of glass over the wood base and seal with silicone so the paint is sealed behind glass.

  18. lefty0mtl says:

    Quick question. Does the heated air you get from this solar heater stink like spray paint?? And if so wouldn’t it be safer to use a non-VOC paint, preferably rolled on to waste less paint at the same time?

  19. lefty0mtl says:

    One idea to save you time on the plywood attachment would be to use flooring screws which have a smooth shank above the threaded screw. Then you wouldn’t have to reverse your drill and ‘pilot’ your plywood every time when you were using those drywall screws. Awesome series of vids!! Thanks.

  20. screamingservers says:

    @Ongytenes Great idea

  21. pirucreek says:

    I wonder if instead of glass you can put steel sheet on top.

  22. brandon14872 says:

    at the first part of the video it looked like a flat screen t.v.

    by the way nice videos

  23. Ongytenes says:

    Do you think if you built vertical thin walls of flashing inside to create a maze to force the air to zig zag through the box to cover every sq in. it would make the heat claimed to be more efficient? I was thinking if the air followed the path of least resistance, there would be pockets of air that would be very slow moving or standing still. You could still pack the wool into the channels to maximize the surface area.

    Great video! Very educational (as they all are)! Keep up the good work! Thanks!
    I look forward to the finishing touches and attachment!

    hahaha I like how he gets all distracted be the helicopter.
