Re: [EVDL] Magnetic Shock Absorber & EV

Peltiers are thermocouples. Either one is technically called a Seebeck
device when generating a voltage from a temp differential.

Thermoelectric cooling's effectiveness is not that great, and few
devices have any sense of very long-term durability. Larger devices can
make a few watts. The thermal expansion and contraction makes thermal
mounting very difficult and stresses the device. Sometimes they
delaminate in a mechanical failure, exposure to elevated temps also
degrades them and eventually causes failure. A temp regulated heat
source greated reduces that problem, but that won't happen in an ICE.
