A turbine and a turbine-generator device for use in electricity generation. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

A hydrocarbon reclamator consists of a closed chamber having an exhaust inlet port, a hydrogen inlet port, and a hydrocarbon outlet port. A magnetic flux is generated at the base of the closed chamber and a rotor is suspended by the magnetic flux within the closed chamber. The rotor is formed as a Tesla turbine having axially spaced discs concentrically mounted on a central shaft, a catalyst is formed on surfaces of the discs, and flow holes are formed through the discs. Venturi forces direct gas to release kinetic energy against the discs, so that hydrogen entering the chamber combines with carbon entering the chamber to form a hydrocarbon that exits the chamber via the hydrocarbon outlet port.

Embodiments of the invention are shown in the figures, where a system for vibration detection is shown, the system comprising: one or more drivelines including a rotatable component rotatable about a rotational axis relative to another component; an electrical machine having a rotor and a stator rotatable with respect to one another, the rotor being arranged to at least one of drive and be driven by a part of the driveline, the electrical machine being adapted to provide signals indicative for at least one of a motion and a force between the rotor and the stator and a torque applied on the rotor; and an analysis unit adapted to receive the signals and to detect a vibration signature of the rotatable component with respect to the other component based on the signals.

A noncontacting intershaft seal system includes force generating mechanisms to reduce contact related effects. A sealing system includes an outer shaft that has a hollow interior. An inner shaft extends through the hollow interior of the outer shaft. Spaced apart end plates encircle and rotate with the inner shaft. A gland opening is defined between the inner and outer shafts and between the end plates. A ring is disposed in the gland opening. The end plates and/or the ring include force generating elements that generate force to separate the ring from the end plates, reducing contact related heat generation and wear.

An impeller is configured to be rotated by a flowing fluid. A fluid stator includes a fixed ring parallel to a plane of rotation of the impeller. The fixed ring has a center in-line with a center of rotation of the impeller. A rotatable ring is rotatable relative to, and parallel to, the fixed ring. The rotatable ring has a center in-line with a center of rotation of the impeller. Stator vanes extend between the fixed ring and the rotatable ring. The stator vanes define an inlet cross sectional area upstream of the impeller. The cross sectional area is dependent upon a relative position of the fixed ring and the rotatable ring. An actuator is configured to rotate the rotatable ring. An electric rotor is coupled to, and configured to rotate in unison with, the impeller. An electric stator encircles the electric rotor. The electric stator includes coil windings.

An electric power generation system receives a gas flow at a heater, heats the gas flow at the heater with a heated fluid from a waste heat process, and directs the heated gas flow to a turbine wheel of an electric generator. The heated gas flow drives rotation of the turbine wheel, and in response to rotating the turbine wheel, electrical current is generated by the electric generator. Generated electrical current is then directed to power electronics.
