Unfortunately the river has a summer rainfall rise of 4-5 meters. what I need is a tube type system secured 1,5 meters below river level at the lowest time of year, against the side of the earth head or rock face. the tube must house all the necessary turbines and ancillaries required to generate electricity. 220v and about 15-25Kv. at a steady 50hrz.. front inflow protection must be provided for floating debris. the only give away will be small bore pipe running up the embankment housing the power cables. the unit must be submerged and out of sight. Do you think a system can be constructed to harness the natural flow/velosity of the water? thanks and regards Arthur Crook. good day Martin,

Probably 100% eff.??? What micro turbine type to fit ?highest efficiency Have you heard of vortex shedding bluff body hydro electric generators developed at the u. of Michigan. Are they applicable.They have less environmental impact. Thank You---Marty Working with the University of Hartford and our water co.on conduit hydro.
to provide energy to filtration plants and the grid as follows
3 conduits;

1. 5 mgd @20ft.= 6KW less 1mile -30 inch diam conduit
2. 20mgd@40ft.=48KW less 1 mile-36inch conduit
3. 40mgd @ 40ft.=96KW less 1mile-36 in. conduit
Assuming straight concrete conduit and use of your calculator. Probably 100% eff.???
What micro turbine type to fit ?highest efficiency
Have you heard of vortex shedding bluff body hydro electric generators
developed at the u. of Michigan. Are they applicable.They have less
environmental impact.
Thank You—Marty

All are Micro class. We wish to harness them but have run into an insurmountable road block in FERC regulations. We wish to sell to National Grid but there is no possible way to overcome the cost of all these FERC exemptions. WHAT SHOULD WE DO? Thanks, Pete We have 50 dams in town. All are Micro class.
