Magnetic wires as "Free Energy"

[BEP]

On the idea of iron wire...

A magnetic field (circling?) the wire is created with current flow in that wire.

If you could make a magnetic field circle a conductor in the same way as the one normally created would that induce current flow in that wire?

If this is possible (why not? many functions are reversible in electromagnetics) then this would explain the application of an external magnet as some form of starting mechanism.

On the use of iron wire as part of the construction of a coil or transformer I've seen reports of 'no core' pole transformers used during shortages during the great wars and in antique radios. Most of this information came from other researchers of this forum.

the reciever coil of a 'crystal radio' is wound out of iron (magnetic) wire, with an air-core

that alone, with a good anteanna and solid earth ground can power a small speaker.

you'll need a diode, otherwise the collapsing field produces an equal but opposite current to flow in the wire and nothing will happen.

Really? I've built more than my share of these radio sets and never used iron wire. I suppose it could work but the wire resistance would change things a bit. All the ones I've heard of used magnet wire (not magnetic wire). Since magnet wire is usually copper and never magnetic I had no problems.

None would drive a speaker directly. Maybe I need to find some magnetic wire?
Interesting thoughts on what the diode does

The modified thermocouple is a thermopile (combining many of thermocouple metals in a "pile"...)
Oops, looks like it will not power Led's....

I think there are modules which can put a  decent amount of power out.  I think thermoelectric generators have a tremendous potential.  There are so many things we have which waste heat, even the sun.

Bmw sees the potential..There's also a company which about a year ago developed an 80% efficient module..

Hard to find any good ones on the web, this is pretty much all I could find atm.

these work great as generators, and run from $10-15, output around 4-7v per module
if you can keep the cold side cool, you can make all kinds of power from any heat source around.

i have 4 of them i used for my candle-generator,
