Abstract :
The ultimate aim of a Moroccan–German study is to develop a simple solar pumping system, using the concept of low delta-T Stirling
engines. This paper describes the main parts of the engine and presents several experimental measurements made under laboratory and
field-test conditions in Morocco. Measurements with flat plate cooler and discontinuous motion of the displacer were conducted to verify
two essential recommendations of Kolin in expectation of power-output improvements of the gamma-type engine.
