The greatest problem of thermoelectrics is the need to maintain very low thermal conductivity.
How is it possible that pyroelectrics do not have this limitation and do not need temperature differences to produce electricity from heat?If we will heat all pyroelectric body uniformly it will still generate electricity,right?I know that pyroelectrics work in impulse maner and should be heated in impulses.Therefore pyroelectrics could be more efficient than thermoelectrics at least in cascade.
Disadvantage of pyroelectrics is that they produce very high voltage.This trait could be used even for nuclear fusion purposes.I thought that it would be valuable to create some material which would have best traits of both.Ability to work in impulses and produce low voltage and high current.
What will happen if we will heat thermoelectric in impulse mode?
