batteries in particular, as well as computer chips,
rerfirgerators and other devices run optimally at a range
of temperatures .
and they also produce alot of waste heat.
these factors are much like warm blooded animals.
scientists have been developing waste heat micro
generators that
are small enough to coat the outside of a
device that is operational and harvest the waste heat.
take these devices, hook them up to small energy
resoivoirs ( electric , chemical, thermal or a spring or
micro flywheel?) to harness and store this energy.
when the temperature of the device gets out of the range
you want, use the heat sink/rerigerator to either heat or
cool the device to its optimal temperature range by
utilitizing the stored energy to either heat or cool the
device.
this would be particularly useful with batteries in cars as i
believe the temperature is constantly changing and
performance could be improved greatly by enhanced
temperature managment on the go. homeostatic batteries
if you will.
