There has been invented a method for producing geothermal energy using supercritical fluids for creation of the underground reservoir, production of the geothermal energy, and for heat transport. Underground reservoirs are created by pumping a supercritical fluid such as carbon dioxide into a formation to fracture the rock. Once the reservoir is formed, the same supercritical fluid is allowed to heat up and expand, then is pumped out of the reservoir to transfer the heat to a surface power generating plant or other application.

The mowing arrangement, as defined in claim 1, wherein a mowing unit carrier frame is releasably mounted to said main frame; said main transmission being mounted to said carrier frame; and an arm being coupled between each mowing unit and said carrier frame, with releasable couplings being made with said mowing units, whereby said carrier frame may be disconnected from said mowing units while remaining coupled to said main frame, or said carrier frame may be disconnected from said main frame while remaining connected to said cutting units. 5. The mowing arrangement, as defined in claim 4, wherein said carrier frame is mounted to said main frame for being moved up and down; and an actuator arrangement being coupled between the main frame and the carrier frame for selectively causing up and down movement, whereby said mowing units are moved together with said carrier frame. 6. The mowing arrangement, as defined in claim 1, wherein said main transmission includes a main transverse drive shaft; said mowing units including first and second side mowing units respectively located outwardly from opposite ends of said main transverse drive shaft; said transmission arrangement of said first and second side mowing units each including a power-receiving transmission having a power receiving input shaft; said power-receiving inputs of said first and second side mowing units being respectively coupled to said opposite ends of said main transverse shaft; and said main transverse shaft being adapted for receiving power from a primary power source. 7. The mowing arrangement, as defined in claim 1, wherein said main transmission includes a gear housing that is arranged off center on said carrier frame relative to a longitudinal center line of said main frame and including a forwardly projecting main transmission output shaft; said plurality of mowing units including a front mowing unit centered transversely on said longitudinal center line; said transmission arrangement of said front mowing unit including a power-receiving transmission having a power-receiving input shaft located in substantial fore-and-aft alignment with, and coupled to, said output shaft of said main transmission. 8. The mowing arrangement, as defined in claim 2, wherein said output shaft of said power-receiving transmission is coupled to an input shaft of said power-distributing transmission by an articulated drive shaft. 9. The mowing arrangement, as defined in claim 1, wherein said power-distributing transmissions are belt drive transmissions that can be turned off. 10. The mowing arrangement, as defined in claim 2, wherein said power-receiving transmissions are one of spur gear or belt drive transmissions. 11. The mowing arrangement, as defined in claim 10, wherein three mowing units are coupled to said carrier frame, with one being a front mowing unit and the other two being right and left side mowing units; said right side and left side mowing units being identical and their power-receiving transmissions being belt transmissions; and said front mowing unit differing from said right and left mowing units in that its power-receiving transmission is in an angled gear transmission. 12. The mowing arrangement, as defined in claim 2, wherein said power-receiving transmission of each mowing unit includes first and second angle gear boxes connected together for pivoting relative to one another; said first angle gear box having an input shaft connected to said main transmission; and said second angle gear box having an output shaft coupled to said power-distributing transmission.
