Hello, was looking for information for a friend, they own small cabin in Alaska  - they have small creek running thru there land  5-8ft wide 1-2ftD in spots, doesn't have no head. Looking for hydropower generator that can be conceal underwater and removeable... from our understanding we can't mount nothing in the creek like water wheel. any help would be great.. 

My understanding they have: 
24V System with 4 trojan  
Magnum sine inverter box
Midnite controller

    The only off the shelf similar unit I can think of is a sail boat towed water turbine:

    You probably need pretty good water speed (something on the order of 5-7 knots or 6-8 MPH) to get them turning out useful energy...

    They use to advertise one in Homepower magazine. Can't think of the name of the company, but I know Homepower has their whole article history available online now. You might try checking that out.
