(1) It uses steam, so high pressure, and expensive Helium which leaks easily is not needed.

(2) It needs no highly pressurized crankcase, so its weight is very light.

(3) Cost of the engine is far cheaper than conventional high pressure Helium Stirling engines, even if low or middle pressure conventional boiler system is included.

(4) Any kind of heat source, as biomass, solar, can be used for the heater of the engine and or boilers.

(5) By experiments, it is known that SSSE and Stirling engine fit to hybrid EV car and boats very well with batteries.

 

The new type engine, SSSE which main parts are the combination of Stirling and Rankine cycle engines, should be widely researched in the world, of 21st century for the use of renewable energy sources.

Especially this should be studied and utilized at developing countries for inland and coast water ways, where multi natural heat sources as biomass and solar etc. are abundant.
