The majority of the electrical power is found to be generated from the conventional sources of energy. Due to the rapid exhaustion of the conventional fossil fuels there has been widespread power shortage throughout the globe hindering the upward progressive trajectory of developing nations. In order to solve this problem, the tangible option is to focalize on development of renewal sources of energy. From the different available renewable sources of energy, we chose to study the scope of hydal (water) energy for solving problems of power generation.Hydal energy is the fastest growing energy resource and most importantly is, easily available. Keeping in view all the vital factors low cost hydal energy has been a primary solution. Earlier practices used turbines, but to meet the requirements of task, we choose a different approach in hydal power generation, in small scale power generation and being environmental friendly. This review is a complied study of different in pipe turbines power generation alternatives and selecting the most efficient option.A general Spherical-S turbine configured to rotate transversely with in a cylindrical pipe under the power of fluid flowing either direction there through is operatively coupled with rotating machine or generator to produce electricity. Two vanes are placed to the shaft in the centre of spherical blades to control the flow. The blades of the spherical turbine are airfoil in cross-section to optimise hydrodynamic flow to minimise cavitation and to maximise conversion from axial to rotating energy.
