Hi there Hydroconversions (smile)
I really disagree with the idea that Steve doesn't know what he's talking about. Can you accept that this is what I believe - Steve has a really good idea of what makes things tick.
I also think that when you ask someone for help and they respond to the best of their ability they deserve thanks.
How to make "Hertz".
Electric power can come in 2 forms - DC and AC.
DC is the kind of electricity that comes from a car battery.
As for AC, imagine you had a light bulb connected to a battery through some switches. You could set things up so that first the light bulb was connected one way round, then the other way round, so fast you wouldn't notice any breaks in the light. So first the electricity would flow in one direction, then in the other. Electricity going backwards and forwards like that is called "Alternating Current" or AC. Of course real AC is never made that way and changes direction smoothly, but the switches explain it a little.
Hertz means number of backwards-and-forwards cycles the electricity goes through every second.
You want to make AC at anywhere between 20,000 and 150,000 cycles per second. This is easy. You could use a 555 integrated circuit (see
https://secure.wikimedia.org/wikipedia/en/wiki/555_timer_IC) to do that. Less than $5.
You need to spend a bit on the power section in order to handle the large currents at low voltages I see you want.
BTW I've met a few people over the years who very seriously believe in the kind of technology you're talking about. None of them has ever shown me anything that wasn't scrawled on the back of an envelope, and none of them has ever had any grasp of physics, and they have all told me that people who study physics don't know what they're talking about - not one of them had an ounce of humility.
If they studied their Joe cells properly would they eventually become physicists and thus disqualified from taking themselves seriously?
What would happen if you personally took up a study of physics? Would you gain a knowledge of electricity and chemistry to aid you in your quest for understanding? The alternative I have sometimes heard is that you would lose some kind of ability to think in a brand-new way, albeit a way of thinking which doesn't seem to me to work.
I started out with the same kinds of questions you need answered a long time ago. I too had impossible dreams, and I set to work to try and find out what is real so I could make my little contribution, because things that aren't real don't work.
