Perception tells me those blades at 4:40 are not proper for water. I dont think you can have a blade been tractioned in the water (or in the ocean for that matter) this way without suffering structural damage. This blade design here is good for airplanes. I think the hydrodynamic solution would be to create a blade more like a corkscrew where more of the blade would be connected to a long hub. You can have corkscrew type blade within a cylinder, etc... Now use your brain!
love to hear it, volume is too low, everything maxed and no hear.
