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...
