Thermionic generator converts heat directly into electricity using thermionic emission rather than first changing it to some other form of energy. A thermionic power converter has two electrodes. One of these is raised to a sufficiently high temperature to become a thermionic electron emitter. The other electrode called a collector because it receives the emitted electrons and it is operated at a significantly low temperature. The space between the electrodes is sometimes a vacuum, ...
