A question about resistance

[Philip Hardcastle]

Re tornadoes

If electrons within a metal are considered as a gas, then a temperature gradient causes turbulence.

voltages are produced in wires due to temperature as we all know.

What is overlooked is the fact that an electron carries heat as well as charge.

So if we create a vortex similar to a tornado then perhaps we can create an electrical generator in a shaped piece of metal fed by heat at the right points and with the exhaust at an apex, and maybe its efficiency could be quite high.

Now this does not rhyme at all, but does it ring a bell?

[Mr.Entropy]

So, from the little that I know, resistance of any given wire,
is determined  by the material it is composed of and by it's diameter,
is that correct so far?

No.  The resistance of a wire is determined by the material, diameter, and length.  The resistance of a particular diameter of copper wire is given in ohms per foot.  You have to multiply by the number of feet to get resistance in ohms.

What would happen if  we create a wire that is non linear?

The resistances of each little section of wire, over which the diameter is pretty much constant, add up to the resistance of the whole wire.

@Philip,

I'm in no position to determine
if what you say holds water,
but it is quit intriguing, to say the least.

Is there a way to release the heat
from the electron instead of his charge?
Is that what happens in commonly found
heating bodies, like in a kettle? 

Maybe there's a way to use that heat
directly without electricity as the middle man?

@Mr.Entropy,

Thanks for the clarification about resistance.
As for the second part of your comment,
I think the image that I have in my head
is not getting through.

What I was thinking of is a wire that
has no sections, but rather a continuous
slope. In such a case the constant will
no longer be the diameter, it would be the
changing of the diameter.

I'm not even sure why I insist on this
point, but it feels like there's something
here that is eluding us.
What might happen if we take a wire
of this kind and make a coil out of it?


Thanks for your time,


Adam.

@Adam,

glad you asked, pls see curled ballistic thermionics on this site (actually misspelt as "Curled Ballisitic")

Clearly heat (kinetic energy) of electrons does work in thermionics to escape the surface of a metal.

What excess energy (kinetic) it has can be used too.

I believe Thermionics is the purest form of free energy available.

@Phil,

Thanks for your input,

I read your thread and it's very interesting.
My background is in industrial design so I
couldn't escape the feeling of a child eavesdropping
on an adult conversation 
Nevertheless I was very impressed with your
attitude and passion, we can all use some of that.

As I already said, my knowledge of physics is
somewhat limited. That might seem like an obstacle
to some, but it leaves me free to fantasize and speculate
outside the restrictions and "laws" of convectional science.

One of the deepest insights I had, as to do with the
shape of things and how it affects the energy flow
in them. My biggest source of inspiration is nature
and the myriad of shapes that it manifests.
Natural shapes have one thing in common,
they are never static. They are always on the move,
without even moving. Ever expanding or ever contracting,
depending which way you look.

@all

Another question that bugs me is about the
piezoelectric phenomena. If I understand correctly,
the current produced by a piezo crystal, consists of high
voltage and very low Amps. So, my question is:
How come a huge voltage with low Amps can pass
through my body hardly noticed, while much lower
voltage with higher Amps will fry me? what is this
mysterious component we call Amps? and why does
it have such a nasty bite?

Thanks in advance for any comments,

Adam.
