I like the idea of running a pump. One of the links showed water pumping where
there is no other source of power. This could be a real plus to people that live
in remote places and need water pumping. One of the things people mention when
they put in water pumping in third world countries is, "who will maintain the pumps?".
Anything that is simple and self sustaining would be much better for those conditions.

I've just added the first photos to my solar stirling web page -
showing an electrical (resistance) heater being used for testing and
the early construction of the wooden prototype parabolic trough frame.

As promised, progress is slow and jerky - but the engine appears to
scale nicely (the most recent engine has a stroke of ~5" with 30W
input).

Many thanks to all who've offered encouragement!

More later...
