How does the 'non-contact' part work if it is a turbine? Wouldn't you have to have a least a bit of the turbine in the flow (and therefore incurring losses because there has to be energy transfer for it to work)? Perhaps the point is that it is pretty small.
The actual application is flooding a backyard ice skating rink...you essentially fashion a shallow swimming pool, fill it up and let it freeze. It takes me about 20 hours to get 30,000 litres from my household supply. I was interested to see how flow changed during that time as other activities (showers, toilets etc.) put demands on the system.
