Folding Solar Panel

    Someone asked about using solar panel on long trips. I did some testing this
    week. My Quest running during daylight with the backlight on and ending with
    a gain on the internal battery. Next I plug the panel onto a drained 12
    volts battery, pack down to 5 volts, on my gage. after more than 7 hours the
    gage read 12.5 volts. details are here;
    http://www.billcotton.com/quest_on_bicycle.htm
    This was a stationary test. I plan to mount the panel on the top of my rear
    pack and tent. However I will have a shadow problem in some directions. But
    when camping without electric this will come in handy.

    Well, ... for one ... I have always been interested in the possibility
    of recharging AA batteries this way while on tour — or simply while on
    rides around home for that matter. It's free energy.

    ----
    Speaking of that — does anyone else have one of those inductive, no
    battery flashlights? I accidentally left mine on for a long time (days -
    in my bike pack) and now I can not get it to stay on more than a few
    seconds at at time - if that (even after shaking it - magnet through
    coil - for two minutes). It must have come with a big charge on the
    capacitor (they will stay on for a couple of days when new). I'm
    wondering how to get that charge back on there. I liked the idea of
    having a "perpetual" and very light weight flashlight in my bike pack at
    all times. But now, it's kaput.

    Can't help you with getting your light working again, but you should
    try the hand cranked dynamo LED flashlights. They work very well and
    it's a more direct motive force than the induction - more reliable.
    Some of them have built in radios.

    I'm betting what you have isn't a true Faraday, and has little batteries and
    not a capacitor?

    It's certainly got a coil and a magnet that slides back and forth
    through it. But I actually have no idea what stores the charge
    (capacitor or small rechargeable battery). Either way, I'm getting the
    idea (after reading more on the 'net) that they are sort of scam.
