A fluidic device is disclosed, comprising an enclosed passage that is adapted to convey a circulating fluid. The enclosed passage comprises a flow unit having a first electrode and a second electrode offset from the first electrode in a downstream direction of a flow of the circulating fluid. The first electrode is formed as a grid structure and arranged to allow the circulating fluid to flow through the first electrode. The fluidic device may be used for controlling or regulating the flow of the fluid circulating in the enclosed passage, and thereby act as a valve opening, reducing or even closing the passage.

The disclosure includes an outer electrode and an inner electrode. The outer electrode defines an inner volume and is configured to receive injected electrons through at least one aperture. The inner electrode positioned in the inner volume. The outer electrode and inner electrode are configured to confine the received electrons in orbits around the inner electrode in response to an electric potential between the outer electrode and the inner electrode. The apparatus does not include a component configured to generate an electron-confining magnetic field.

Magnetic fluid partially fills a channel built into the main body an object (or mechanically attached to it). Magnetic fields are selectively applied in a controlled manner so that the magnetic fields actuate the magnetic fluid into motion and thereby actuates the main body into motion by applying a force to the channel which the magnetic fluid partially fills.

An apparatus for generating electric power from the motion of a vehicle according to the disclosure includes: a magnetic fluid storage unit in which a magnetic fluid is stored and from which the magnetic fluid is discharged by a pressing force of the vehicle; a pipe unit through which the magnetic fluid discharged from the magnetic fluid storage unit moves; and an induction coil unit arranged to surround a circumference of the pipe unit so that an induced electromotive force is generated when the magnetic fluid moves.

In some examples, a system can include an electronic device and a cooling system that transfers heat among other components of the system. The cooling system can include a pipe that contains a fluid, for example. In some examples, the cooling system can further include a magnetic piston, one or more electromagnetic coils, and a power supply. The electromagnetic coils and power supply can generate a magnetic field that moves the piston to cause the fluid to circulate in the fluid pipe. In some examples, the cooling system can further include a magnet and one or more pairs of electrodes coupled to a power supply. The magnet, electrodes, and power supply can generate a Lorentz force that causes a conductive fluid to circulate in the fluid pipe.

The present disclosure describes systems and methods for using an ionizing fluidic accelerator that may encompass the use of an ionizing fluidic accelerator including a substrate, an electron emitter having a negative bias and being formed on the substrate, an anode having a positive bias and being formed on the substrate, and an attractor having a negative bias and being formed on the substrate. The electron emitter and the anode may be separated in a first direction and the negative bias of the electron emitter and the positive bias of the anode may produce a first electric field in the first direction. The anode and the attractor may be separated in a second direction, the positive bias of the anode and the negative bias of the attractor may produce a second electric field in the second direction, and the second direction may be orthogonal to the first direction.
