"Hydrovolts' floating Flipwing turbine is simple to deploy and connect. Just drop it in the water and tether or anchor. No dams, weirs or site preparation are needed, reducing costs and minimizing environmental impacts..."

Paravane generator in focus here: http://www.hydrovolts.com/

Scalable. Any flowing water: tether to relatively fixed device.

Any static water:  drag the paravane using a moving system, perhaps an air kite.
