Claim 10:
11. A system for generating power in the vicinity of a drilling rig during drilling operations, the system comprising:
a drilling fluid container to store an amount of drilling fluid;
a container pipe positioned in fluid communication with the drilling fluid container;
a drilling fluid pump in fluid communication with the container pipe;
a drilling fluid pipe including a first end and a second end, the first end of the drilling fluid pipe connected to the drilling fluid pump so that the drilling fluid pump pumps drilling fluid through the drilling fluid pipe during operation;
a drill string including a proximal end and a distal end, the proximal end of the drill string connected to the drilling fluid pipe, the drill string configured so as to define a cavity for drilling fluid to flow therethrough;
a drill bit connected to the distal end of the drill string and to rotate based on rotation of the drill string and flow of the drilling fluid;
a drilling fluid return pipe positioned above a subsurface geological formation and to receive return of drilling fluid flowing therethrough during operation;
a heat exchanger connected to drilling fluid return pipe and positioned to facilitate heat transfer from the drilling fluid to a working fluid flow; and
a power generation unit to generate electrical power by use of the heat transferred to the working fluid flow.
