Claim 4:
5. A method for generating power in the vicinity of a drilling rig, the method comprising:
operating a drilling rig to form a borehole in a subsurface formation;
sensing, via a sensor, an ambient temperature of the drilling rig;
during operation of the drilling rig, selecting one or more fluids from one or more corresponding heat sources based on the ambient temperature of the drilling rig, the one or more fluids selected to flow to one or more corresponding heat exchangers, each of the one or more corresponding heat exchangers positioned to transfer heat from one or more corresponding fluids to a flow of a working fluid to generate a heated working fluid, thereby to cause a power generation unit to generate electrical power; and
in response to a determination that the ambient temperature exceeds an engine operating range, adjusting an amount of flow of the one or more fluids to the one or more corresponding heat exchangers.
