Abstract
A high-efficiency turbine generates energy from a fluid flow, such as wind or water currents. The turbine has a central axis with a plurality of foils rotatable about the central axis in a general paddlewheel arrangement. Each of the foils has a foil axis parallel to the length of the foil and the central axis, and is rotatable about its foil axis. During operation of the turbine, each foil assumes an attack angle to the direction of the fluid flow with the attack angle dynamically controlled about the foil axis as the foil rotates about the central axis so as to maximize the foil's moment about the central axis.
