Claim 13:
14. A system to generate geothermal power, the system comprising:
at least one mobile heat generation unit; and
one or more conduits configured to divert a flow of heated fluid from one or more heat sources to the at least one mobile heat generation unit,
the at least one mobile heat generation unit including:
a pair of heat exchangers mounted at elevated positions adapted to facilitate access,
a pump configured to pump a flow of a working fluid through the heat exchangers,
a first fluid path extending through the heat exchangers and along which the flow of heated fluid is received from at least one of the one or more conduits and is directed through the heat exchangers,
a second fluid path extending through the heat exchangers and along which the flow of the working fluid directed through the heat exchangers for indirectly transferring heat from the flow of heated fluid passing through the heat exchangers along the first fluid path to the flow of the working fluid passing through the heat exchangers positioned along the second fluid path to cause the working fluid to be heated so as to change phases from a liquid substantially to a vapor, and
an ORC unit including a generator, a gas expander, and a pump, the ORC unit positioned such that a substantially closed fluid recirculation loop for the working fluid is defined between the at least one mobile heat generation unit and the ORC unit when connected to the second fluid path of the mobile heat generation unit, so that during operation the flow of the heated working fluid into the ORC unit causes the generator thereof to generate electrical power via rotation of the gas expander of the ORC operation, after which the working fluid is cooled so as to cause the working fluid to change phases to the liquid phase, wherein the liquid phase working fluid is recirculated back to the at least one mobile heat generation unit for reheating.
