DAVID: How are you installing this contraption and how are you expecting in generating the power and what is the area you need to illuminate >???
Many questions indeed and what is the life you hope to have ?. I can not follow your procedure or thoughts so detail to understand if you have a feasible system. What is the velocity of the river in the area of interest, the volume, depth etc. Regards Nando ----- Original Message ----- From: "dnmillrod" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Saturday, February 19, 2005 12:11 PM Subject: [microhydro] Planning a homemade waterwheel for kayaking spot in river > > > > There's a kayaking "playspot" on the Delaware river between NY & NJ > called "Scudders Falls".
