Hello,   thank you for mentioning me!   ARCHIMEDES SCREW Archimedes screw are efficient micro hydropower converters. At the moment, for practical reasons, the maximum diameter of the screw is 4 m, that corresponds to 8 mc/s of flow rate, so maybe you would need of two smaller screws. Here a my brief article, with a picture with three screws in parallel. https://www.prescouter.com/2016/11/hydrodynamic-screws-archimedes-electricity/ Consider that for installiung a screw you need an hydraulic head, i.e. a drop in the channel bed.   WATER WHEELS   The same reasonings written for Archimedes screws are valid. In this case the flow rate that the wheel can use depends especially on the width of the wheel, in addition to the diameter. Also in this case you need an hydraulic head. https://www.prescouter.com/2016/10/water-wheels-hydropower/ http://www.sciencedirect.com/science/article/pii/S0360544215005344   Otherwise, if you want to install a water wheel in flowing water, you can use a floating water wheel, but the efficiency are lower. please, give as look to this my article. https://www.prescouter.com/2016/11/hydrostatic-pressure-energy-production/   Regards
