Lucid spherical turbine Power System is a water- to-wire energy recovery solution. Lucid spherical turbine is an in-pipe turbine generator to capture the energy of fast-moving water inside of large, gravity-fed pipelines, converting it into a continuous source of low-cost electricity. Unlike other renewable energy systems, Lucid spherical turbine produces predictable, base load energy with no environmental impact. The Lucid spherical Power System can be installed in a day and energy generation can begin in less than a week. This keeps permitting and installation costs low and project returns high. This electricity can be used on-site to power pumps and other devices, to charge storage systems, or to connect to the grid for net metering.

INTRODUCTION Overview of Turbine: A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. A turbine is a turbo machine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery. A turbine is a machine that transforms rotational energy from a fluid that is picked up by a rotor system into usable work or energy. Turbines achieve this either through mechanical gearing or electromagnetic induction to produce electricity. Types of turbines include steam turbines, wind turbines, gas turbines or water turbines. Mechanical uses of turbine power go back to ancient Greece. The first wind wheels relied upon gearing and shafts to power machinery. Windmills and water wheels are forms of turbines too and might drive a millstone to grind grain, among other purposes. Thermal steam turbines driven by burning oil or coal or the use of nuclear power are still among the most common methods of producing electricity. Green electricity applications include wind turbines and water turbines used in applications for wind power and tidal power. Because of the turbine’s many applications in a wide variety of technologies, research is still ongoing to perfect turbine and rotor efficiency. Hydrokinetic Turbines: A "Hydrokinetic" turbine is an integrated turbine generator to produce electricity in a free flow environment. It does not need a dam or diversion. In stream Energy Systems has coined the phrase Instream Energy Generation Technology or IEGT places turbines in rivers, manmade channels, tidal waters, or ocean currents. These turbines use the flow of water to turn them, thus generating electricity for the power grid on nearby land. In effect, IEGT is like planting windmills in the water and is
