Abstract: An energy conversion system includes a stationary structure and a rotatable structure configured to rotate relative to the stationary structure. The system includes at least one blade member mounted to and extending radially outward from the rotatable structure. The blade member is configured to interact with fluid currents to cause the rotatable structure to rotate about an axis of rotation. The system includes a first magnetic bearing component disposed on the rotatable structure and a second magnetic bearing component disposed on the stationary structure. The magnetic bearing components have an aligned position in which the components are axially aligned along the axis of rotation with respect to each other. Axial displacement of the magnetic bearing components from the aligned position generates a magnetic field between the components that provides an axially-directed restoring force between the rotatable structure and the stationary structure to reposition the components to the aligned position.

Abstract: An apparatus for performing magnetic electroporation is disclosed. A required electric field for electroporation is generated using a pulsed magnetic field through a closed magnetic yoke, such as a toroid, placed in a flow path of a fluid medium to be processed. The fluid medium flows through the orifice of the magnetic yoke, with the fluid medium flowing through and around the yoke. The required power to send a maximum flux through the magnetic yoke is less than the required power in a conventional apparatus for performing electroporation.
