I wonder if I used this method to spin a Faraday Disc
http://hackedgadgets.com/2006/05/26/hard-drive-platter-tesla-turbine/

Would I land two birds with one runway?
And would the liquid mercury brushes splatter all over the place?
Would a custom fender cover that problem?

uh?  I had a lot of time on my hands the last two days.
but it doesn't make me a spammer, all my ideas went
into the correct forum catagories.  But ok, I'll cut back
on the coffee.

As for the Idea of spinning a faraday disc like you would
a Tesla Turbine, what's wrong with that?  This is after
all, the "Half Baked Ideas" section.  It could even spin
several at 15,000 RPM, but just realized this is "Brushless"
Sorry, I'll shut up and listen, hoping you solve the problem,
as it would be a great breakthrough.

Paranoid?  me? ...er?  you're only asking that to set a trap, and use the answer against me later, but I'm not falling for your trick question.

Hey, what would happen if microamp HV was introduced to a spining Faraday Disc, via Wimshurst Machine, or other device, tipping hat to Diode along the way, would the output of the Faraday Disc then have a higher voltage, while retaining it's high amp boasting rights?
Thus allowing more efficient brush use?

It works with cocktails.

Maybe I can send Low Volt High Amps from Faraday Disc to giant Joule Thief.
Which would in theory give me spikes of High Voltage, whilest maintaining high amps.
A Great Dane works the same as a Chiuaua.

oh, ok well the best way I heard for extracting the most current
was to run the disc through a pool of mercury, but as I said that
was a hand cranked model, over 1oo years ago, and the mercury
is (I assume) considered a "brush"?  But I will think on this.

Well "Half Baked Ideas" under any other name,
is still usually where most of the world's best
inventions came from.

That Illustration looks interesting.

I was wondering (forgive me if it's already been mentioned)
But I was wondering if a jet of water were used to spin the disc,
the way air or water spins a Tesla Turbine, would that water
conduct a current like a brush, but not slow down the wheel?
It is after all, the driving force.  How well water conducts is
another story, well, not "well water" but,..

...what, ...one Starbucks is all I had.

.....what if we mimicked the way lightning formed.....

PhoneBoy,
I'm thankful for the submission of course,
but could you share your thinking a bit more ?

The set of numerous things that happen in the formation
of charge/finger/discharge in lightning lends me to need to ask.

Which phase are you referring to?

Here is what I can say is probably and error on my part.
A direct short to the disc has three possibilities.

The disc melts,
the shorting bar melts,
but most probably the brushes/contacts melt (First).

So the heating issue would have to be carefully persued.

But the idea you have has merit
as long as you change your idea a touch.

The disc needs to build the potential
across the whole disc's surface.

But if my original question is stands true,
and the potential can be harvested from the edge
without contact that is in motion in relation to the disc.

Then an insulator across the majority of the disc's surface,
but allowing your idea to make conact at the center and edge only.

Might yield a viable idea.

But I want to understand your idea still.
Charge to plasma is an awsome concept to follow. 



Edit:
Upon thinking this over,
and as my original question still stands.

Whom is to say that a pair of disc's
with opposite magnet forces acting upon it
don't have a potential dipole at all points
of opposing face from the center to the edge.

If true, a medium sensitive to the dipole
could and would react to advantage. 

There are other liquid metals less toxic than mercury.
Can build these with the shaft vertical, and wheel horizontal,
Then use the Bill Beaty Pipe Cap Brush Design.
