Sinusoidal blade apparatus

An apparatus for manipulating a substance, the apparatus comprising:

• a blade having a fin hub associated with a fin formed by a sinusoidal outer edge and an inner surface extending from the sinusoidal edge to a center of the fin, wherein the sinusoidal outer edge surrounds the inner surface, the fin hub being associated with a portion of the sinusoidal outer edge of the fin, such that to cause the fin hub and the fin to rotate simultaneously about a rotational axis that is coaxial with the fin hub;
• wherein, when the blade rotates about the rotational axis in said substance, said substance is simultaneously pulled in via two opposing vortexes that are coaxial with the rotational axis, toward said portion of the sinusoidal outer edge of the fin, and said substance is also simultaneously pushed out 360 degrees around and away from the rotational axis.

A blade comprising:

• a fin having a sinusoidal outer edge and an inner surface extending from the sinusoidal edge to the center of the fin, wherein the sinusoidal outer edge surrounds the inner surface;
• and
• a fin hub associated with the fin.
