Many people believe that Stirlingengines as part of a hybrid electric drive system can bypass all of the perceived design challenges or disadvantages of a non-hybrid Stirling automobile.
Approximately one hundred years later, the term "Stirling engine" was coined by Rolf Meijer in order to describe all types of closed cycle regenerative gas engines.
