What are the advantages of Thermionic Power Generators?

There are certain advantages to thermionic generators over other energy converters, such as a traditional Carnot heat engine, which converts heat into mechanical energy in the form of work. One benefit of the thermionic process is that there are no moving pars in the system, which allows for very long operational lifetimes. Furthermore, thermionic converters can be fabricated at a much smaller scale than the Carnot engine, which opens the door for possibilities of thermal energy conversion at the microscale.
