high magnetic fields cause motor wires to move, this invention uses a polymer like hypersilk, buckminsterfullerenetube, or kevlar that is much stronger than Cu to keep the winding geometrically on spec. The silver plating just happens to outmass the polymer, while being more conductive than Cu to create a stronger motor wire of equal or greater conductivity
This might be particularly advantageous at the size of power plant generators, as the higher dimensional regularity creates an opportunity to narrow the space between the rotor n other magnet thus giving greater efficiency-- beanangel, Feb 03 2012 this says Ag is 9 pt. more conductive than Cu, so replacing an equal mass of polymer with Ag should be a conductivity benefit above Cu wire http://wiki.answers...ptholene_conductive [beanangel, Feb 04 2012] 5800 power plants at US, 25 or 30k globally, so each pt. efficiency at the generator is like 250 or 300 power plants http://205.254.135....s/faq.cfm?id=65&t=2so thats 25-30,000 powerplants globally 1/100 of that is 250 or 300 entire power plants of energy [beanangel, Feb 04 2012] aerogenerator figure http://www.scientif...rst=421&FORM=IDFRIRScientific American image of a windturbines wires, the higher voltage moderates the eek its too simple looking feeling [beanangel, Feb 06 2012, last modified Feb 08 2012] This might be more practical for very thin wires, bit if you check the cross section of a typical conductor in a power plant generator I think you might agree that silver plating is not going to be a thin coating on the top of something else.-- Ling, Feb 03 2012 Could be used for more efficient motors in electric cars (or terminators).-- DIYMatt, Feb 03 2012 //The silver just happens to outmass the Cu// so ?-- FlyingToaster, Feb 03 2012 What, precisely, is "hypersilk"?-- MaxwellBuchanan, Feb 03 2012 I assume it's harvested from pan-dimensional silkworms.-- spidermother, Feb 03 2012 That would be tricky - shirley they live in wormholes?-- MaxwellBuchanan, Feb 03 2012 Baddum-tish.-- spidermother, Feb 03 2012 Equal or greater?
Pshaw! No element known to man conducts as efficiently as silver.
Too bad it rhymes with nothing. What a star it would be otherwise.-- Zimmy, Feb 04 2012 Apart from superconductors, of course. Also, copper and several other metals have a greater conductivity than silver by mass.-- spidermother, Feb 04 2012 Niftiness, I appreciate the replies. The idea value is that if generators are 1/100 to 1/20th more efficient as a result of creating higher intensity magnetic fields with more dimensionally stable, narrowly spaced windings then this technology represents dozens or hundreds of power plants of energy.
I have always been impressed with the person that created amorphous transformer alloy, raising the electrical efficiency of everything 1pt. I am kind of making an effort to find an even niftier technology, thus the superwire as well as polepieces on conductor ideas.
If I were an engineer I might be pleased to have created an entire power plant, this could create the equivalent of dozens or hundreds of power plants energy with the same amount of motion (wind, hydro, OTEC) or fuel currently used
Silver is described online as 9 pt. more conductive at volume, which is what would be preferred to create the highest magnetic field. The wire gets to have the same diameter even though it has a strengthening polymer core occupying some volume.
hypersilk is my casual way of describing the published silks produced from genetically engineered mammal milk. Last time I saw a thing on it, it was stronger than the strongest ferrous metals less strong than kevlar thus far.
This effect may also have relevance. As electrons like to travel on the outside of a conductor, its possible that silver coated wire has a few pt. greater magnetic field at the surface to create magnetic motion as the electricity prefers both the outer area as well as the silver. do you think it will work?
the other critcisim I thought might have occured was that a coil differs from a weave, how does the polymer actually keep things tight? The thought there is that the polymer core could occasionally surface-- beanangel, Feb 04 2012 How about replacing the wires entirely with plasma?-- MaxwellBuchanan, Feb 04 2012 Haven't they done that with some of the super-sensitive detection equipment on the LHC? I know I read something having to do with low-temperature plasma conduction or some such. Hang on, I'll go see if I'm remembering it correctly.
<later: never mind, it was a plasma lens for proton _collection_, not a conductor. My mistake.>-- Alterother, Feb 04 2012 //the faraday effect says electrons like to travel on the outside of a conductor// No, the Faraday effect is something different. You may be conflating two different things:
· Charge accumulates on the outside of a charged conductor (but that's irrelevant, since we are interested in current, not charge).
· Current flows more towards the outside of a wire carrying alternating current (the skin effect). I considered that, and it does favour hollow conductors, but it's only important for very thick wires or very high frequencies, so I didn't bother to mention it.-- spidermother, Feb 04 2012 I rewrote the annotation to make more sense-- beanangel, Feb 04 2012 [beanangel], I would like to share some stuff that I've picked up over the years - the reason for doing this is just to provide food for thought...
Electric machines (motors, transformers), have 2 basic losses which are of any importance (ignoring eddy current losses, friction losses):
1. I squared R losses 2. Magnetisation losses
The first is related the the power loss in the windings which goes up in proportion to the resistance, but also by the square of the current. It would seem that reducing the resistance is good, but reducing the current is better. Current can be reduced by increasing the voltage. Voltage can be increased by using better insulation. Did you know that power station generators typically operate at 2300V only, and are stepped UP for transmission? Also, they are cooled by Hydrogen (!) for best heat transfer, and least windage friction losses. You will probably be already aware of the ever increasing voltage of power distribution due to better materials. This is purely for efficiency. The magnetisation losses are due to the area in the B-H curve of the material. But if the air gap is bigger, more current is required to generate the magnetic field (see I squared R losses). It is a strange thing that we are taught, in high-school physics, that a current carrying conductor experiences force in a magnetic field. However, in a motor, the magnetic field bypasses the winding and is concentrated in the magnetic material around the winding. How, then does the conductor experience a magnetic field? It is probably the interaction of the magnetic field from the winding in the local magnetic material around the winding. Then one could suppose that the center of the winding has a bigger 'air gap'.
The final thing we could mention is that the efficiency of these machines is variable according to load. For example, at no load we have magnetisation losses, so the effiency is, Um, pretty bad. The magnetisation current is generally regarded as fixed (it's a good approximation). As the load increases, the I squared R losses rapidly increase. The maximum efficiency of the machine might not be at full load...but generally it is. The point that I am making is that if the machine is highly efficient, but then operated at the wrong point, it is also not a good overall design.
Hope this stuff is useful to know.-- Ling, Feb 05 2012 [Ling] much appreciated you have given me a bunch to think about, your previous comment about a generator idea actually caused this one.
Perfect field printed rotor
I was thinking that a 3d printer could actually print the perfect bigger diameter of conductors at the perimeter along With just the right magnetic alloy so the insulated wires were actually mingled with the alloy, further noting that a disk rotates more rapidly at the edge than the center you could use magnetic alloys of different hysteresis amounts at variously perimeter, middle, center of the rotor to always shape the field better as well as make it oscillate with higher efficiency-- beanangel, Feb 06 2012 So, maybe (silver core, polymer coated wire) would work better?
Apologies if I've misread, it's late.-- csea, Feb 07 2012 I have a very dumb question, probably. With conductive materials serving as the wire's 'jacket,' how do you prevent the current from simply shorting across the wires rather than travelling along them all-orderly like?-- RayfordSteele, Feb 07 2012 Speaking of printing, has Polymagnet considered applying their printed magnet technology to motors and generators?-- notexactly, Jun 09 2019 random, halfbakery
