1. A method of generating a geothermal well, comprising:
drilling a geothermal well comprising an entrance and an exit at a surface, wherein the entrance and the exit are in fluid communication via a path, the path comprising:
a first segment extending between the surface and a target depth, the first segment comprising the entrance;
a second segment in fluid communication with the first segment and extending radially outward at the target depth, the second segment being substantially perpendicular to the first segment;
a third segment in fluid communication with the second segment and extending in an arc at the target depth;
a fourth segment in fluid communication with the third segment and extending radially inward at the target depth; and
a fifth segment extending between the target depth and the surface, the fifth segment comprising the exit, being in fluid communication, and substantially perpendicular to the fourth segment.
