Hello Ian, Collegues of mine have recently launched a floating 500KW turbine which is placed behind an existing low head (let's say 2 meters) dam. Once the turbine has put down its aspiration conduit into the lower level the siphoning process can start. In fact it is half floating as the machine has four hydraulic legs. It only can be floated at some distance from the dam once the conduits are empty.
These guys have installed some floating watercurrent turbines in Africa in spots where the water have a velocity close to 2meters/second. These machines are in the 5 to 10 kw range. In one specific project where I have been involved the machine is the only source of electricity for an hospital in the jungle. They come now with a new concept of a bigger machine able to produce theoretically up to 500 kw. I have been suggesting to them to start with a project in the range of 20 to 100 Kw. So if you or somebody from this group have the feeling to know a spot where such a project could be implemented, please contact me.
