GDY is much more advanced and also has the best site in Australia which non of the others can match.
Others yet to drill a hole that far down, and do not own their own drill.
I will not buy into any of these until GDY has proven their drilling. The others are far behind.
If GDY fails due to the technology all the rest will follow.
keep an eye on GDY's drilling in the next few months when the rig arrives. If it works there will be plenty of money in geothermal for all to gorge themselves.
I like the technology but will wait alittle longer.
