step forward for hot rock technology ignored!

The news of the progress petratherm achieved in their major fracture stimulating work last week must be a plus for KUTH but the market seems unimpressed. Creating a fracture zone at depths of 4 km is an important and daunting step in proving that the theory behind enhanced geothermal heat exchangers is a technical feasability ( let alone economic). Still lots of huge steps to achieve but it is encouraging to see the feasability of the concept being progressed and not costing KUTH anything. By this time next year Petratherm may have established a second well and sufficient circulation of fluids to be building their pilot plant.
No way KUTH s.p. will be languishing then.
