Definitions

• Typical turbine system comprises of rotor blades that traps the wind flow or the water flow energy to do rotational motions, in order to generate electrical power.
• alternator Power generation for smaller application like air/water surface and air based vehicles uses alternators.
• An alternator has a rotor, driven by belts to generate electrical power to provide power vehicle and charge battery.
• the rotor has to be driven by engine or other apparatus.
• an alternator is not practical for capturing wind or water flow energy. See, for example, U.S. patents 6897575 (2005), 7566980 (2009), 5998903 (1999), 6740995 ((2004), 6455946 (2002), 7629719 (2009), 20060208581 (2007).
• the present compact wind water turbine is designed to omit the use of rotor, belts and rotor blades. It is designed to substitute for or phase- out previous shaft-mounted rotor blade based turbines. [0011 ] It is also contemplated to integrate or assemble the components of the
• CWWTSTM into any shape or space. Due to its space saving concept, there is no need for rotor blades, lengthy shaft and a huge standing structure. [0012] Most components are concealed inside the housing equipped with trappers, such as vanes. The housing rotates due to trapping of fluid flow energy and results in producing electrical power by a concealed generator in the housing. In an embodiment the generator and housing are supported by a center shaft that includes an inner-coil. [0013] As a substitute to the rotor blades and shaft, there is now a housing that is rotating.
• Coil rotation can be set to be stationary or rotational. When outer coil is stationary inner-coil rotates, When inner-coil is stationary, outer-coil rotates. Also both inner and outer coils can be set to rotate same time if desired. Concealing electrical power generating generator into the inner structure of housing saves space. The trappers function is to trap fluid flow energy, for example, from wind or water flow. [0015] The housing has these features;
• Compact wind and water turbine is designed to produce the power as per requirements. Due to its flexible design capabilities; it can be designed for large, medium, small, compact, mini, and micro turbine. It can be integrated into any shapes, in any positions of the structures.
• a device can be manufactured in any size. It can generate power from minimum to maximum, per requirements.
• a CWWTSTM can be beneficially incorporated with any moving object that operates on surfaces; air and space, where the moving objects can take advantage of air or water flow energy. When water and air flow energy is constantly rotates the housing, the flow of electron is generated that generates electric current, which can, for example, supply charging current to the power storage device or electrical devices and other components. This enables vehicles operated by electric, battery or power storage devices and hybrid motorized moving objects, to travel for longer period without having to stop for recharging the battery. Besides providing constant and uninterrupted electric power supply, the concealed generator and compact design is a significant feature of this device.
• Compact wind and water turbine system can be installed in any place where energy can be extracted from fluid flow energy by generating electrical current, for example, under or on the surface of flowing water, in any water or air conduits, such as, for example, in water lines, sewer lines, rivers, canals, gas- exhaust pipes and stacks, in any windy location, such as wind farms (where it can substitute for massive rotor blades based, costly, complex, and conventional wind turbines), in addition to on moving objects (either through the water or air) as described above.
• a CWWTSTM Due to its compact design, a CWWTSTM can be integrated into most structures in any position. It can be use for residential applications and reduce the load on the power grid. Installing multiple units can increase the electrical power generating capacity and redundancy.
• Clustering multiple compact wind and water turbine system units can increase or decrease electrical power generating capacity and redundancy. Also in case of failure, repair, replace, maintenance or upgrade, is easy and simple. An individual unit can be replaced without shutting down the entire system. Having multiple unit has advantage of running system constantly with minimal to none down time.
• the turbine is long regarded as renewal and clean energy source, however, it has not been successfully applied on the surfaces of land, air and space- based vehicles.
• Compact wind and water turbine is designed to apply for many applications. Air, surface and space based moving objects will benefit most. Also this technology will help reducing carbon foot print and help reduce harmful gas in our environment.

• the housing is configured to rotate by the force of the trappers, and includes an interior hollow that is the space enclosed by the housing. Within this space or interior hollow is enclosed the electrical generator, including rotors and stators.
