Looking to build a simple solar powered hi voltage low current power supply

  1. I need to build a solar powered colloidal silver generator. To treat my
    water on camping trips. As both a practical way to treat water for drinking
    and for the
    coolness factor of having built something practical that does not need

    I've built DC voltage multipliers before with the diodes and caps in a lader
    fashon. They are not very efficient. So I know I need to build an RL
    then I guess I need a transformer to step up the voltage.
    I would like to step the voltage up to at least 600 volts or as high as 2k
    I don't need much current. The device I use now is a simple three 9 volt
    batteries in series with .999 fine silver for the cathode and for the anode.

    I treat a solution of distilled water which I then pour into the water I'm
    From what I understand the higher the voltage the more stable the silver
    ions in sollution, and the greater the percentage of nano-meter sized silver
    which are the most effective at killing bacteria, fungi, and virus's.

    At just 5 parts per million this sollution is said to kill bacteria in 4 to
    5 minutes
    with no toxic side effects.

    This sollution will even kill pathogens like Anthrax, Small Pox, and

    Thanks in advance for any ideas or input!

    AFAIK you can't 'generate' silver from electricity !

    No, you have to drive a wooden stake through its heart.

    This simple circuit will output around 50 volts with no load.

    go for the second example - the one called "A Circuit Enhancement"

    You can just as easily wind a secondary for even more output voltage
    if you want.

    The silver is supposed to come from the silver electrodes - they
    corrode leaving some super small particles suspended in the water.

    In theory at least . . .

    Silver has bacteriostatic properties and is a weak bactericide.

    Personally, I think the "colloidal silver" hype is just a lot of
    snake oil, but someone has to test this crap . . .

    Copper might be just as effective without the electrolysis since it
    tends to be a much stronger bactericide and corrodes fairly easily,
    but unlike silver it is easier to OD on too much of a good thing.
  8. A few years ago I designed the hardware to automate the filling of
    water cooler bottles. The company had a patent on how they did it, but
    they used colloidal Ag as the steriliser, and it passed all the
    bacteriological tests.

    That's impressive. Any idea of the quantity of silver in suspension
    and how they measured it?
  10. It wasn't that impressive, about 3 or 400 lines of C on an 8051, most
    of it was system self checking, and extreme idiotproofing and a rugid
    optical isolated i/o interface.
    It was straight linear drop through C, very simple

    They just gave us the Ag solution, the containers only had "
    sterilising fluid" on them. In those days I didn't even know it was

    The 3-400 lines of C on an 8051? 3-4 hundred lines of code on an 8051

    So I guess you're saying that there was a way to check the strength of
    the fluid you were being supplied?

    I wondered more about the detection technique. Conductivity or
    particle size, automatic titration or something more sophisticated?
    Did you check the solution itself or the rinse water?
  12. ISTR at89c51, but since the systems were hired out, there was
    significant datalogging, checking flow rates and to prevent

    We used a simple conductivity meter, (10V dc, 100K resistor, and a
    comparator) to make sure they didn't try and swap the sterilising
    agent with a bottle of water, or try to run it without the sterilising

    There was no testing of the fluid, in the software specs

    Oh. I worked in pharmaceuticals we had several grades of water
    cleaner than drinking water.

    "Water for Injection" the highest standard for normal use. Pyrogen

    "Reagent grade water" as good as WFI but with a known assay of

    And "water" in 15 ml flame sealed vials certified by the NBS or
    traceable to them - presumably this was hydrogen and oxygen and
    nothing else.

    D.I. and distilled - for the crude work like dissolving tablets
    rinsing glassware etc..

    I've heard all the colloidal silver stuff from a cousin discovering
    her spirituality in California . . . so I attach some skepticism to it
    (despite, or perhaps because, I lived in CA)

    It is interesting to know that someone thinks there's a real reason to
    be using the stuff.

    and prompts the question " would we be better off with silver
    goblets?" In my case, beer mugs.

  15. That doesn't work on lawyers. You'd need a toothpick.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

    well on a cloudy rainy day you will have no water. neverthless a solar panel $15 12v output a LM555 and a diode cap pump may gets you there from 120 i got 15kv at 12 volts that is going to be way down. power is my concerne a 12 volt solar is as heavy as 5 9v battery so i would say possible but not likely.
