A vortex generating apparatus has the capability of attracting and removably adhering one or more solid objects. The apparatus comprises an impeller housed within a shell. The vortex attractor generates a vortical fluid flow generally in the form of a helical or spiral shaped flow. The fluid flow creates a low pressure region extending from the impeller end of the device. This low pressure region is contained by the walls of the fluid flow, thus directing the attractive forces toward a surface and minimizing effects of ambient fluid on the system. When t...
1. A method for providing a substantially recirculating cylindrical vortex fluid flow creating a low pressure region comprising the steps of: providing one or more rotatable impeller vanes coupled to a containing ring; rotating said impeller vanes; reducing parasitic fluid flow through said impeller vanes; and constraining said low pressure region to a desired location; wherein said substantially recirculating cylindrical vortex fluid flow creates a low pressure region that results in an attractive force. 2. A method according to claim 1 wherein sai...
