You know how we have wind turbines scarring (and killing birds) our hills, mountains and valleys, well this idea is based on the same principle. Using horizontal turbines and placing them in our rivers, streams, waterfalls and oceans is a vast, potential source of free energy. HGenergy.com is already experimenting with 2 projects on the Mississippi (one near a dam with the grid close). Think of the old Sutter’s mill. Horizontal turbines placed in a waterfall could generate significant energy. The turbines (Hgenergy.com has their own version) could also be placed on the side of rafts and respond to tidal flow in the oceans. The potential is enormous.
