Great news!
Now, who gets to him first? I understand that Ron Davis (whose
September 04 posting caught my eye) also wanted to find him.
Ideally, I would like to locate someone in Europe with a unit as I am
based in Morocco and even Peru is a bit of a hike from here.
On a more practical note: my renewed interest in this unit is due to
my awareness of some potential micro-hydro applications in the Atlas
mountains but also because it would appear that in the right
circumstances the same type of unit could be suitable for a wind-power
set-up.

George
