I was being shown a new hydro plant at our local river a few days ago (From

technical as he could go on the topic).

This meant that in time of high flow it is throttled back considerably.
Isn't it possible to generate DC and convert it electronically to AC?
Wouldn't this mean that higher speed would give more amps?

yebbut it costs more and river flow generation is lousy on output anyway.

Maybe he meant that at *full* flow the generator would exceed the
designed output and overheat?
