How does a water mill with a vertical turbine produce electricity?

Answer 1

In the same manner as a turbine with a horizontal one, by the water moving the blades. its tha rotation that generates the power. The alignment of the shaft doesn't matter, its the force transferred to the generator/alternator that matters.

There shouln't be any significant change in the turbine blades.

It may be easier in certain designs to couple the generator set to the shaft if its mounted vertcially in some locations.

Answer 2

There must be overpressure of water on the input side of the turbine - by the height of the water column or by the flow of the water. I guess that the previous alternative gives more constant pressure against the turbine blades but I also know cases in Scandinavia where a vertical turbine is installed in a power plant by a big river, next to previous horizontal turbines.

Answer 3

Basically water is introduced above a large turbine and the water falling through the turbine causes it to rotate (like a ship's propeller working in reverse). This drives a shaft which is attached to a generator set (generally also vertical and placed above the turbine) which produces electricity.
