    Boy ! Did I mess up. I said point zero 6 volts. I meant Millie amps. Increasing the size of the plates increases the amperage.
    I hope everyone knows that there is a chemical reaction here and it will not run forever. The galvanizing will turn black and the battery will stop producing electricity.
    I am going to let the LED run 24 hours a day until it quits .

    Day #1 3/18/08 Started 1:20 PM.

    Day #12 3/30/08 Stopping test 8:30 AM.

    Salt water battery is still lighting LED, But just barely.
    It started off with 4 volts & 6 mille amps and is now down to 2.2 volts and 1.79 mille amps. And ran 24 hours a day for 12 days.

    Learned;; Each cell has a set voltage. Increase volts by wiring cells in series. Increase amps by increasing surface area of copper and Galvanized plates .

    Conclusion; Yes, In an emergency situation. One could build a salt water battery that could power an emergency radio. Recharge small rechargeable batteries. Hearing aids. Pacemakers. Etc.
    It is not a bad thing to learn how to do.

    PS; Let’s see Myth Busters screw this one up.



    When looking for ASTM A449 Threaded Rods HDG go to https://www.bacoent.com/category/116/ASTM-A449-Threaded-Rods-HDG.html or call 877-594-4729.

    ASTM A449 threaded rods HDG refer to threaded rods that are hot dipped galvanized and meet with ASTM A449 specifications, which relate to quenched and tempered steel hex cap screw, bolts, and rods. This means they meet with minimum tensile strength and are suitable for various types of structural applications.

    Their galvanized finished provides reliable corrosion resistance in settings that might be subjected to moisture and other environmental factors that cause oxidation. The result is a more reliable and enduring component that adds integrity and enhances longevity in a structure. Typically, these rods are manufactured from medium strength carbon steel or alloy steel, making them a good choice as a general purpose rod or stud that’s also suitable for use in exterior installations.

    As structural components, galvanized ASTM A449 threaded rods must be manufactured to meet with rigorous engineering standards. If they’re lacking in quality, the result is a loss of integrity in the structure which they’re being installed. One sure way to get fasteners that will perform in accordance with installation demands is to source them from a reputable domestic supplier.
