  7. To figure your efficiency though you must figure the amount of sunlight
    blocked from warming objects that it would have shined on.

  8. you should title this passive heating down south, because this would not
    work in the north east. lol.

  12. what was the room temperature difference? is that the goal? to keep
    people warm or to cook eggs on the window? ;o)

    Do you guys get enough snow to play around with snow forts? I live in Phx
    - but with the possible mini ice age comin (ck out suspicious 0bservers if
    you get bored one day) I only say because he explains the trend of
    temperature extremes (vs “ice age” like the media propagates) and it makes
    me go hmmmm and recall the scriptures about how after the end times perhaps
    implying the sun being very insufferable (yet 1/3 of the lights in heaven
    go out) confusing kind of like its confusing now with all the wacky weather
    globally :) Also, I want to go cave hunting (because for some reason
    there are indications that everyone is going to be running for them – not
    sure if we’ll be here at that point or if we’ll have caught air – won’t
    hurt to know my area tho. Happy Friday!!!!

  14. So you can’t heat when it’s snowing, just sunshine days?

  15. What about adhesive backed velcro attachment? Instead of chalkboard paint
    how bout a “window scene”? ;) )

    This will also help out with light discipline when thing go south.

    Good stuff brother.

  16. Awesome, God bless!

  17. Great video! Thank you!

  18. Thank you for another easy inexpensive prepper project. It may not heat a
    large house, but should, at a minimum, reduce the need for other heat
    sources (gas, wood, oil, etc.). Saves some money!

  19. great idea.thx

    By b h on Mar 4, 2015

  22. Wow. Very cool !!! I work in a factor in the recieving dept. TONS of
    cardboard. I have some to black out my windows in an emergency, but now
    I see they can be used for even more. Thank you!!!

  23. Thinking of doing something like this to heat a green house using thermal
    mass water barrels… Much less water than a pool…

    By Mike Warner on Mar 4, 2015

  24. Did you have any results to share from this? I was thinking of building
    exactly the same setup.. keen to know if this can have any impact on
    heating a pool?

    By Dean Attewell on Mar 4, 2015

  25. Also many thanks for sharing

    By Aaron Williams on Mar 4, 2015

  26. I am looking forward to Part 2 and any performance data you may have.
    Wifey has horses and wants me to build something similar to your heater for
    her stock tanks.

  27. Other than cost is there other reasons for not using copper tubing

    By Aaron Williams on Mar 4, 2015

  28. What a great idea! How has it worked? You could focus mirrors or a fresnel
    lens (from an old TV) on that, It could probably handle colder temps than a
    less massed solar heater or be placed inside a window and not lose any
    heat. I bet it would heat your bale shed with no problem while
    thermosiphoning a 30 gallon drum. That would be interesting. Probably too
