How does a water turbine make electricity?
The water turbine is powered by a flow of water, like a stream or ocean waves. There are blades that extend into the flowing water, causing the blades to turn a shaft. The shaft is then attached to a generator. The “generator” “generates” electricity by turning. Inside are copper windings that spin around a magnet. You could easily get an old generator from a junked car in a salvage yard. Then it’s a matter of using gears to change the turning force of the blades into the needed speed of the generator.
