Hi Don:

further to your reply on feb 02 I thank you very much for all the information.

I am quite knowledgeable on many different types of water wheels and turbines but the one you describe sure has me baffled. I am familiar with the undershot types of wheels but any that I have seen were never completely submerged in the manner you descibe.

Turbines are completely submerged and work well only in this state, I have heard of wheels that were placed in fast flowing sections of a river to capture the motivation of the water current itself without the expense of constructing a dam, they were though usually very prone to ice damage in the northern climates.

What you are describing is very interesting and I would very much like to learn more of this particular technology

Thanks again

NH
