For, hydroelectric, you buy, off the shelf, little, one house sized generators. You hook up a pipe from upstream ,and run a pipe downstream. The amount of power you get out is based on the distance dropped.

Cooling is done by burying a pipe, at least 9 feet down. Where the temperatures stay the average of the air temperature for the year. Usually about 60°. Under a stream is even cooler.
