Summary
| Description |
English: Illustration of two basic setups for closed-loop geothermal systems. One, called a U-tube, is where cool water is pumped down one deep vertical pipe, which then extends horizontally for a certain distance at a depth where the rock is hot and then comes up in a different location. The other, called a tube-in-a-tube, is where the cool water is pumped down along the outer layer of a pipe to a certain depth, and then the pipe takes a 90-degree turn and extends a horizontal distance at that depth. Then the hot water hits the end of the pipe and is pushed into the inner pipe, back up the way it came. |
