Hydro-electric >30kw anyone done one?

I am interested in this as I have an irrigation supply channel through my place which runs about 500 megalitres a day. The only regulator on my place drops 150cm.

What sort of hydro generators are available that could just be dropped in the flow.

Any sort of undershot wheel normally found on barges in rivers would work

An old school friend installs this for a living. Henry's site is here.

I can't vouch for his work but he has won lots of awards, may be worth a call

not really many but I think with a drop this low you would be looking at a vortex :

This only my thinking on vortex systems, unless this vortex is in the southern hemisphere, would it not be better if the rotation is the same as a bathtub plughole? There is no point in going against nature.

There is a very minimal effect that would not be seen in moving water:

Bang goes my theory!
