Stirling in deep space

Article Abstract:

The author discusses the impact of NASA's decision to replace the existing radioisotope thermoelectric generators with new and cheaper system called the Stirling technology. The new process is found to be based on an old invention that provides more power with less fuel and hence can easily be used in deep-space studies.
