A self-operated incinerator system is disclosed. The self-operated incinerator system comprises: an incinerator; a steam boiler configured to receive waste heat from the incinerator so as to produce steam; a turbine device configured to generate a turbine rotational force by receiving the steam produced by the steam boiler; a generator configured to generate power by using the turbine rotational force generated by the turbine device; and a storage battery configured to store the power generated by the generator and to use the power for starting or normally operating at least one from among the incinerator and the steam boiler.

A turbine arrangement for a bi-directional reversing flow is provided. The turbine arrangement may include a rotor rotatably mounted to rotate about an axis of the turbine arrangement, and the rotor may have a plurality of rotor blades disposed circumferentially thereabout. A first set of guide vanes may be circumferentially disposed about the axis for directing the bi-directional reversing flow to and from the rotor blades via a first flow passaged defined by a first duct. A second set of guide vanes may be axially spaced from the first set of guide vanes and circumferentially disposed about the axis for directing the bi-directional reversing flow to and from the rotor blades via a second flow passage defined by a second duct. The guide vanes may be disposed at a greater radius than the rotor blades, such that the guide vanes are radially offset from the rotor blades.

A turbine wheel (100) for a turbocharger includes a hub (110) and blades (120). The hub includes a primary outer surface (116), a back wall surface (115), a peripheral edge (119) extending between the primary outer surface and the back wall surface, and a central axis (111). The hub has a back wall thickness measured parallel to the central axis from the primary outer surface to the back wall surface. The blades (120) extend from the primary outer surface of the hub and are integrally formed with the hub by casting. Each blade has a blade thickness measured tangential to the central axis between opposed surfaces of the blade. A maximum diameter of the peripheral edge is 60 mm or more. Over a majority of a radially outer region (117), a thickness ratio of the blade thickness to the back wall thickness varies by 25% or less. The radially outer region extends from the peripheral edge to a 25% meridional.

Kinetic Energy Electric Power is an ecofriendly method of producing utility-scale electricity. It does not need high pressure steam to operate, there is no need for expensive steam turbines, nor do any of its operating plants need to be placed within any particular geographical location or weather condition such as sunny, windy, near water, etc. This invention is driven by heated air flowing through a system of solar thermal panels containing mineral oil, or another suitable heat-retaining liquid, that is circulated within a closed circuit piping network through one or more thermal energy storage tanks then through heat exchangers located in one or more large heat chambers that have a chimney stack extending skyward in order to facilitate the draft of air. As the air inside the chambers is heated and expands, it is forced out the top, because of stack effect, through the chimney, thus forcing fresh air to flow in through an opening at the chambers' bottom that brings outside air in via a passageway and travels through one or more paddlewheel-like wind turbines that drive multiple large, weighted flywheels that have multiple electric generators attached to them via gear/clutch mechanisms and producing utility-grade electricity 24/7, 365.
