Solar well pump using stirling technology, looking for realized project

[assembler]

hi all,

i am looking for a documentation of a realized and working system
consisting of a solar well pump using stirling technology.
Something that allow me to demostrate the feasibility of such a project.
the system should feature very simple tech and low cost.

does anyone know if there is something like that on the net??

There are a couple on youtube that people had made.  Not sure how much they will pump.
