Solar Scorcher -- Tests heating water

  • Solar scorcher that I finished building. Fresnel lens came from a free, 50" Toshiba rear projection TV. Framed up with 2x2, but I still need to build an adjustable table in order to place things within focus of the lens, or near focus, depending on the application.

    i Liked your practical uses with the 'Fractal Lense'.... :)
    Grant's Version is rather extreme, but demonstrates it's full potential.
    Thankyou for your video. It was very informative.

    The hottest the water is going to get is 212 with it being an open system. Steam is taking the energy away with it.

    Hello! Im very interested to buy a big fresnel lens. Im looking for a flexible one, with around 1mx1m size. Its not gonna be used in solar issues, instead Ill film a video with the lens creating visual effects.
    Can anyone give me some information?

    Thanks in advance!

    Heat is escaping through the hole used to pour the water out. Try a pressure cooker so that energy from inside cannot get out.

    I wonder about the other vids, the screws and other objects were melted so easily and reaching over 2000 degrees?  Was it a factor of the distance to the Object as well as the lens magnification?  I'm sure he uses a spot lens, now I wonder about the magnification?

    Be careful! I  made one of these from a TV magnifier lens and went inside to get some stuff. I got delayed and when I went out my deck was on fire! Very dangerous !  Never, ever leave these things unattended! FYI

    Hey there, I'm looking to build one of these too, what would you say is the max temp you can get out of your setup on a good sunny day?
