Abstract
Systems and techniques relating to blades, in particular to symmetrical blades for turbines. In one general implementation, the present application relates to a method for increasing efficiency of a symmetrical blade comprising providing a rigid portion of the symmetrical blade and providing a flexible portion of the symmetrical blade. The rigid portion of the symmetrical blade can be connected to the flexible portion of the symmetrical blade. The flexible portion of the symmetrical blade can be adapted to bend with a flow across the symmetrical blade. The symmetrical blade can be adapted to rotate in one direction for a bi-directional flow across the symmetrical blade. The symmetrical blade can be adapted for at least one of a Wells Energy Conversion (WEC) system, a fan, an exhaust system, a blowing system, and a suction system. The rigid portion of the symmetrical blade can be fixed to an axis perpendicular to a direction of flow. The symmetrical blade can be rotated in a direction orthogonal to the direction of flow and orthogonal to the bending of the symmetrical blade. The rigid portion may comprise metal, wood, and plastic. The flexible portion may comprise plastic and rubber. The symmetrical blade may comprise a pear-shaped blade or a rectangular-shaped blade.
