The gear ratio needed to drive a generator can be ridiculous! Wide water wheels are best for pumping and other low-RPM mechanical tasks.

Most micro-hydro generators use a Pelton wheel, which spins very fast. A Pelton wheel is effectively a bunch of spoons. Water is squirted directly into them using a nozzle. At least 20 PSI is needed to efficiently generate electricity.
