Thermal energy in choke valves

Provide a detailed explanation of a new way on how to convert the thermal energy in choke valves to electric energy. For example, how to use “Ni45Co5Mn40Sn10 alloy” in the choke valve and how exactly it can turn the heat into electricity if used inside the choke valve. I need at least 3 patents number as work cited. also include a detailed sketch of this can work.
