I have been studying the use of Archimedean screw turbines, specifically for low head uses, does any one on here know how small a scale they could be manufactured to be able to generate a useful amount of electricity.Huh

Most of the ones that I have seen on the web seem to be rather on the large size (but very fish friendly) Cheesy

i seem to remember seeing from Germany this was a wind turbine but its design could also be used underwater as well.

it was not so much of a screw but it had 3 blades that were horizontal and  twisted with bearings at both ends , there was no maximum speed that t would run at so it was immune from the stronger gusts of wind, but i liked the fact that it's design could also be used under water

The Ritz-atro Archimedes Screw Turbine that Billi supplied the link to is distributed in Ireland by Ei-Hydro Ltd and Wind Water Solar Ltd.
They claim a 25-40 year design life and can operate for low heads of 1m to 10m.

We camped at River Dart country park last year (Dartmoor), they had an Archimedes screw design turbine running there. Can't remember how many KW it was generating - although if you google it one web site says it's a 48KW installation. I recall the video they had of fish swimming along the screw while it was turning.
