Abstract
A fluid displacement device including a center shaft and a plurality of vanes. Each of the plurality of vanes has an inner edge, an outer edge, and a spiraling edge disposed between the inner edge and the outer edge. The spiraling edge of each of the plurality of vanes follows a Fibonacci spiral based on circular arcs traced through a Fibonacci tiling comprising squares having side lengths that are a multiple of at least five successive Fibonacci numbers.
