Sievers, R., Hunt, T., Hendricks, T., Barkan, A. et al., "AMTEC Internal Self-Heat Pipe," SAE Technical Paper 1999-01-2660, 1999, doi:10.4271/1999-01-2660.
The alkali metal thermal to electric converter (AMTEC) technology has grown tremendously over the past 10 years. Innovations such as wick pumping, remote condensing and multi-tube cells have advanced the technology substantially. New innovations have been identified that will further advance the technology. The internal self-heat pipe (ISHP), for example, is predicted to increase the efficiency by a full 3 points. Proof-of-principle tests have been completed, and prototype testing is about to begin. This paper will present the design concept and available test data for this new AMTEC innovation.
