T1 - The Litho-Jet method - an essential requirement for the economical realisation of the geothermal power systems JF - Acta Montanistica Slovaca N2 - Currently, there is a global problem of an increasing need of energy. There will be less fossil fuel, which will be more expensive in the future. The regenerative energies are getting more and more important. The subject deals with the problem of economical feasibility of geothermal energy systems. Its goal is to analyze nessesary conditions and aspects for realizing geothermal energy systems in comparison to and competition with traditional energy sources. The geothermal energy recovery is economically advantageous if the investment costs, esp. the drilling costs, could be reduced significantly. It only seems possible to open up a big opportunity for realizing geothermal energy systems by using a rock melt drilling technology, to reduce the investment costs significantly.
