Hydropowered turbine system

A hydroelectric turbine, comprising a base member having a fluid inlet, a fluid outlet in said base member above said fluid

• inlet and being positioned to allow fluid exiting said base member to exit in an upward direction,
• a vertical rotor shaft having lower and upper ends and a vertical elongated axis,
• means for supporting said rotor shaft with one end thereof adjacent said fluid outlet,
• a plurality of spaced arcuate blades having upper edges secured to the end of said shaft adjacent said fluid outlet, and partially extending into said fluid outlet,
• said upper edges having a parabolic shape and dwelling within a parabolic-shaped spherical plane.

• said base member having a hollow cylindrical compartment below said fluid inlet,
• a needle valve slidably mounted for vertical movement within said compartment, and adapted to be moved from a lower open position to a closed upper position above said fluid inlet,
• and a fluid conduit connecting said fluid inlet and said compartment at a location below said needle valve to permit the fluid pressure above and below said needle valve to be substantially equalized.
