Micro turbine drilling set to improve the efficiency of geothermal systems

Scientists at Fraunhofer, Europe's largest application-oriented research organisation, have developed an innovative tool that enables additional branches to be drilled off of the main well of a deep geothermal system, which decreases the risk of dry boreholes and improves the output.
