..IMO...the unexpected tapping of high pressure water at Karratha and the subsequent trauma has stopped everything until the new well-head is installed. I believe WS was simply focussing on a Geothermal application [his passion and a good Greenie] for the GT's. What happened at Karratha "threw a cat amongst the emu's]...so next time the unexpected happens, I hope it won't be water but OIL!....always lookin' on the bright side...LEE
