<p>A natural geothermal power generating system is provided and comprises heat exchanging means being arranged to receive water. The heat exchanging means comprises a plurality of heat exchangers (26a...h) connected in series, each successive heat exchanger being located in rock at a greater predetermined depth below the surface of the Earth than the previous heat exchanger. Turbines (6) are located above the heat exchanger closest to the surface of the Earth, and a substantially vertical riser passage (40) extends from the lowest heat exchanger up to the turbines. Naturally generated heat from the rock surrounding the heat exchanging means converts the water in the heat exchanging means into steam which rises up the riser passage at a pressure capable of driving the turbines.
