I think they could do with a graphics overhaul for their presentations. Check out PAX - their presentations are extremely professional looking. Otherwise the details look good.

I wasn't aware of their East Gippsland project (or maybe I had just forgotten about it). Why are the major geothermals in Australia (PAX aside) going for more difficult and risky EGS implementations for their first Aus projects? I would have thought a HSA project would be less risky and quicker to market? Any ideas?

Also, I have recently been trying to figure out what this HEWI system is. The web site says: "Petratherm's unique "Heat Exchanger within Insulator" (HEWI) model which aims to achieve "low risk, low cost, higher return" is different from other EGS companies. The HEWI model (refer figure below) contends that significant cost and risk reductions can be achieved by creating the requisite underground heat exchanger within the naturally permeable and porous insulating rock above the granite heat source." I take it the model therefore is to create a reservoir/heat exchange system by fracturing the sedimentary layer above the granite rather than the granite itself, is that all it is?

Cheers in advance, BB.
