hot rocks pioneer tries volcanic area, page-4

Considering the run on the other geothermals, it seems like a good top-up time for PTR. I wonder what the scale for expansion would be using volcanic thermal systems? PTR has it's focus set on becomming a sprawling multinational, but the and interesting and pending development is if their low cost/devlopment risk HEWI model is successful.

Does anyone know enough about the non-volcanic Spanish geology to speculate whether HEWI will be applicable there?

If this technology is viable, then PTR may surge ahead to lay claim to the highest GEO market cap, and rightly so. Quite a big 'if', but what isn't down this speculative end of the market? Definately worth buying at these current prices.
