Thermoelectricity is typically associated with the breaking of the electron-hole (EH) symmetry. Here intriguingly we show that a paradigmatic EH symmetric system such as superconductor-insulator-superconductor (SIS) junction could generate nonlinear thermoelectricity that
could reach very high values. This is a consequence of the spontaneous breaking of EH symmetry. Further, we will provide sufficient and general conditions for nonlinear thermoelectricity which are valid also well beyond the superconducting paradigm. Finally, 
we will present other applications such as thermoelectric switch/memories and thermoelectric relaxation oscillators. In the second part, I will discuss the non-local thermoelectricity in Cooper pair splitters as a consequence of the non-local EH symmetry induced by nonlocal entanglement would.
Non-local thermoelectricity can be used to identify helical edge states for topological materials where the hall bar geometry cannot be designed. Finally, I will discuss how topological hybrid Josephson junction can be used to manipulate the entanglement in Cooper pairs and easily measure it with a standard critical current measurement.
