Description
TITLE
Water Turbine Engine for an automobile FIELD
Water turbine engines.
BACKGROUND
Electrically-powered automobiles, due to limited battery technology, require recharging with a range of about 200 miles, and have proven expensive. Full-scale use of electric cars requires the implementation of massive inffrastructure. A need exists for an efficient, low maintenance and low emissions form of transportation.

The outlet is in fluid connection with the water tank. The outlet is configured to transfer spent water from the at least one turbine vane back to the water tank.
Water at high pressures is injected onto the blades of a turbine to achieve the rotation of a spinning wheel. Spent water is scavenged back into at water tank and re-injected onto the spinning turbine. The turbine may have a single blade at a fixed angle, or rows of two or more turbine blades at different angles.

DETAILED DESCRIPTION
A water turbine engine generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 4C.
Structure and Relationship of Parts:
Referring to FIGS. 1 and 3, the basic concept of water turbine engine 10 is illustrated.
Water turbine engine 10 consists of a water tank 12, a high pressure pump 14, a jet inlet 16, a turbine 18, an outlet 20, and a secondary pump 22. Water from water tank 12 is pumped by high pressure pump 14 into jet inlet 16. Jet inlet 16 is preferably oriented to jet pumped water along at tangential location of turbine 18, in order to transfer the maximum amount of mechanical energy of water pressure to turbine 18. Water is then collected through outlet 20 and pumped back to water tank 12 using secondary pump 22.
Referring to FIG. 3 high pressure pump 14 may be provided as a 2hp electric motor, for example a portable utility pump. Typical portable utility pumps have a maximum flow rate of 350gph and produce a pressure of 300-500 psi. High pressure pump 14 may have a throttle valve 24 controlling volume and pressure flow into jet inletsl6.
Throttle valve 24 controls the rate of spin of turbine 18. Turbine 18 may be provided as a conical rotor impeller with at least one set of waterflow vanes 26. Vanes 26 may have diameters of, for example 7-2 5 21 inches, and vanes 26 may be provided as blades. Vanes 26 are connected for rotation about a drive shaft 36. Vanes 26 may be mounted to drive shaft 36 using rivets (not shown). Jet inlets 16 direct water flow to vanes 26 at 90 and 270 degrees, for maximum power transfer.
An additional pump 28 may be provided to pump water from water tank 12 back to high pressure pump 14. Turbine 18 is connected to a freewheel gearbox 30. Freewheel gearbox 30 is designed to couple or decouple flywheel 32, in order to change speeds.
Flywheel 32 may be heavy weighted. Referring to FIG. 2, flywheel 32 connects to a continuously variable transmission 34 by a drive shaft 35. Transmission 34 may be manual or automatic, and may include a clutch (not shown). Water turbine engine 10 may be powered by a battery, a gas or electric engine, or a combination thereof. An example of a battery may be a 12 volt automobile battery. Water turbine engine 10 is preferably used to power a small automobile, for example a tuk-tuk or a motorcycle.
Referring to FIGS. 4A-4C, different configurations of jet inlets 16 and vanes 26 are illustrated. There may be at least one jet inlet 16 provided. Also, there may be various or multiple configurations of vanes 26. Turbine 18 may have a single vane 26 at a fixed angle, or rows of two or more vanes 26 at different angles. Multiple turbine vanes 26 impacted by two or more water jets becomes essential when higher power output and higher engine speeds are required.
Advantages:
The power and torque of the engine is achieved by precisely controlling the pressure, volume, and direction of flow of water. Thus, as compared to combustion engines, noise is reduced, and there is no combustion or exhaust and therefore no greenhouse gas emissions.
While the engine operates in a closed loop, it may be necessary to top up the water tank periodically.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiments without departing from scope of the Claims.
FIGS. 4A-4C are a series of side elevation views showing different jet inlet arrangements.
