摘要： Embodiments of an apparatus for generating electric power from flowing seawater are disclosed. Embodiments form fluid channels having magnetic fields through which seawater will flow. Electrodes are arranged with respect to the fluid channels and connected together such that electric power is generated as seawater flows through the channels.

摘要： The present disclosure describes aspects of in-body power harvesting using flowing fluids. In some aspects, an apparatus comprises a magnetic field generator configured to generate a magnetic field to deflect charged particles of a fluid flowing through the body in a space formed by a vessel. The charged particles include positively and negatively charged particles, which the magnetic field deflects such that the positively charged particles are deflected in a first direction within the space and such that the negatively charged particles are deflected in a second direction within the space generally opposing the first direction. The apparatus also includes electrodes configured to harvest energy based on a difference in potential between the positively charged particles and the negatively charged particles. The harvested energy is convertible by a converter coupled to the electrodes into electrical power that is usable by an electronic device.

摘要： A method of producing a charge separation in a plasma having a low particle density which comprises a plurality of electrons and a plurality of positive ions. The method includes generating a magnetic field and passing the plasma having a low particle density along a first axis through the magnetic field. The magnetic field is generated having a component which is perpendicular to the first axis and is configured so as to deflect the plurality of electrons from the first axis and allow the plurality of positive ions to travel substantially undeflected along the first axis. Also provided is a magnetohydrodynamic generator and a low earth orbit thruster making use of the charge separation mechanism.
