  2. +Jerry Yuen hi there. yep, i’ve tried it without cans or screen mesh. the
    temperature, on average, is 25 to 35 degrees lower without either. (the
    screen absorber “build video” has footage of that test)

  3. Did you somehow make sure or test if the air flow is identical? The
    temperature alone does not cover thermal performance…?

  4. Deer hunters talk about a nice quiet way to stay warm in the blind? Duck
    hunters too. I bet you can face these to the South and stay nice and warm.
    Stealth campers this would be ideal to stay warm? Ever thought of adding a
    vacuum tube to the box? Wonder what type temps they would kick off. Can you
    run vacuum tubes without water? We know water boils 212 well I have gotten
    water to boil with a vacuum tube in the sun no reflector or collector in
    about 45 min with a collector I hear they will boil water in 15 min.

  5. saw one made with metal lath mesh, bent at angles to increase surface area
    in box.
    does the angle to the sun have a major effect to the temperature?

  6. Great comparison. My vavourite absorbers are blinds from thin, black strips
    of aluminum. Give them a try and you will be surprised.

  7. Hi there, is a great simple design. And great comparison video. Have you
    done a temp measurement on just the empty black paper lined box with glass
    only, without cans or mesh. I am curious to know what the temperature
    reading.

  8. So not much difference if any and the screen absorber is probably easier to
    make. I was going to make one with some black aluminum photo foil. I think
    that would be easier than cans and last longer than screens in that heat.
    Just a thought. Nice job. I enjoy all your videos.
