Re: [EVDL] Magnetic Shock Absorber & EV
Danny said "Peltiers are thermocouples."
Here is a clarification from http://www.its.org/node/3767
Effect 1 is what I was refering to as thermocouple. The idea I had was
to take strips of iron and copper and create a long accorian folded
isolated thermopile that mounted on the exhaust manifold. Wide strips
for current electrically in series for a higher voltage.
Effect # 3 is what I refer to as a peltier, in that it takes 2
complimentary junctions of special materials.
International Thermoelectric Society.
Whilst it is generally accepted that there are only three thermoelectric
effects, it is in fact possible to describe four.
The four thermoelectric effects, listed in chronological order of their
Effect 1 - If two different conductors are joined and the two junctions
are maintained at different temperatures, an electromotive force is
developed in the circuit.
Effect 2 - If a current flows in a circuit consisting of two different
conductors then one of the junctions is heated and the other is cooled.
Effect 3 - When a temperature difference exists between two points in a
single electrical conductor an electrical potential is established
between the points.
Effect 4 - If a current passes through a conductor in which a
temperature gradient exists, this current causes a flow of heat from one
part to the other.
These effects are very closely related. Indeed, each of them represents
a reversible effect whereby effects 1 and 2 are the reverse of each
other, and effects 3 and 4 are similarly the reverse of each other.
Thomas Johann Seebeck first identified Effect 1 in 1821. He spent the
rest of his scientific career measuring the size of this effect for
different pairs of dissimilar conductors in contact with each other.
Seebeck died in 1831.
In 1834 Jean Charles Athanase Peltier first identified Effect 2, the
reverse of Effect 1. Peltier died in 1845.
Significantly later (around 1854-1855), William Thomson first deduced
and demonstrated BOTH of the effects numbered 3 and 4.
Starling and Woodall partly describe Thomson's contribution thus (from
"Physics", Longmans, 1950):
