A power generation device includes a housing, chambers, and conductive fillers. The housing has a rotation axis. The chambers surround the rotation axis and located inside the housing. The conductive fillers respectively filled in the chambers. The chambers include electrodes. The electrodes are located on the chambers and in contact with the conductive fillers.

A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

Described are toroidal devices to produce steady state, helical, Taylor-Couette-like magnetohydrodynamic singular structure flows in plasma or other conductive fluids with full magnetohydrodynamic helicity. Linking of two or more such toroidal devices can be used to generate a laminar kinematic dynamo. Only one is required to confine plasma at the pressures and for times required to produce nuclear fusion. Such high-temperature plasma can also be used for centrifugal ionic separation, nuclear transmutations at production quantity, and in the near term as a study tool in the development of materials to withstand high temperature and neutron flux. Plasma is a high-energy state of matter capable of relativistic velocity en masse, and as such, relativistic plasma or other conductive fluid devices are a means to generate gravity.

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.

This proposed system provides a method to generate electrical power for space-based orbiting satellites, probes, stations, habitations, and interplanetary missions. Electricity is generated by collecting the flow of ionized plasma in the solar system for low earth applications and in the solar wind beyond the earth's magnetosphere, then directing the plasma through a channel using the principle of magneto-hydrodynamics (MHD). The channel has conducting electrodes on two sides and a magnetic field directed orthogonally to the plasma flow direction. This results in an electrical current to power spacecraft functions such as batteries, communications, propulsion, guidance, navigation and control. This MHD generator has the potential of providing higher power generation density (e.g., watts/kg) for spacecraft than photo-voltaic panels. The design includes a control system to maintain voltage quality, regulate electromagnet power and control ion inlet scoop RF frequency and voltage in response to changing space ionized plasma conditions.
