I'm sorry I'm having trouble replying to my own post and those of other
writers in this news group using Google groups.

My thinking tends toward rather divergent novel posts anyway which are
difficult to relate to previous posts so it's not a total loss of advantage.

Today I have a significant development to report in my efforts to construct
a homopolar bicycle hub suitable for deceleration, theft resistance,
potential energy capture, and limited maneuvering assistance such as
driving the outside wheel in a very sharp turn on tough terrain, and
backing a tricycle up which is a feature that almost no tricycles have and
I mean human power tricycles here human electric hybrid tricycles.

So that said the homopolar makes use of the generator term in the faradays
law I stated in my other post on Maxwell's equations and faradays law. The
generator term is the positive term in the sum for e the electric motive
force. The alternator term is the negative term in that sum.

Well I've been tinkering with a small machine tool using a plastic chuck
called the unimant one. I've owned one since 1987. I've gripped a small
ring magnet made of neodymium iron boron alloy in the three jaw chuck on my
machines tiny headstock which is separable from the rest of the machinery.
Then what happened that is the development is this:

I had been toying with the idea of using a plastic core armature to measure
voltage induced by spinning the magnet rapidly with the driver motor from
the unimat. I gave up that idea. I ordered an inductor stock from Digi key
and it has a ferret core which is fairly strongly attracted by the magnet
on the chuck.

Well what happened today is I realized that if I insert plastic sheet or
washers between the magnet and the ferrite inductor I can establish a
uniform gap with variable friction and explore and plot and that is the
crucial part of many scientific and diverse, plot out the relationship
between the gap and a limiting current plotted on the y dependent axis
which would be the current at which the things stops being stalled assuming
that I can get any motion at all and that the heat does not melt the
plastic.

So I really wanted to share this with you all in case I need one has
explored homopolar motors in the physics lab. One vendor and I believe they
are in Czechoslovakia provides a homopolar motor disproof kit which
establishes that no EMF is generated even when the magnets rotate. I don't
have that kit so I can't report on the null result.

A fully developed homopolar bicycle hub motor would have North Pole facing
North Pole with a gap between, and an armature wound with a toroidal form
having some turns of wire, the core of the armature being a soft magnetic
material. Other components made of soft magnetic material would complete
the magnetic circuit and ferrofluid can be added to increase that
completion effect. In I am nowhere near there.

But I am making progress and I do like to report progress.

This reply is just a comment about a dream I have also. In my
schedule of things is to get advice about a drone motion power system.
The drone is supposed to be flown to a location just above a tower
system of high tension power lines. At a near distance the ac electric
field just might have enough power to cause drone linear motion. I
would need to, I believe, make a coil system that causes a linear motion
alternator. I believe the main issue is how to state the imaginary
component of the field. Like in an alternator. The force as effect is
an issue. Can I just make a generator field and AC or DC power a
propeller. Or can the coil magnet system directly cause repulsive force
in the flight direction.

I can't reply as a theorist, but my impression is the amazing existence
of an alternator.
