Abstract: The behavior of fluids in an accelerated frame of reference has led to a novel concept known as the Rotating Frame Bernoullis Equation. A very important application of this equation is in the design of the centrifugal field rotor pump. This is a centrifugal rotor with tunnels discharging the fluid into a chamber at high pressure. Here, liquid at low pressure enters the fast rotating tunnels in the disc, where it is acted on by a centrifugal force field. The pressure of the liquid increases due to the centrifugal effect on it, as it flows through the tunnels to attain the pressure in the discharge chamber. This process of increasing the pressure of a fluid without a work transfer, but via the effects of a centrifugal force field is referred to as a Centrifugal Induction Process (CIP). Here, due to a change in the centrifugal potential energy of the flowing fluid, work is done internally by the centrifugal weight of the fluid on the fluid, thus increasing fluid pressure. When the high pressure liquid in the centrifugal rotor pump is conveyed through the outlet to power a water turbine, it then establishes a new phenomenon known as the Centrifugal Hydro-Power Concept, which is very similar to the present conventional Gravitational Hydro-Power Systems. Analyses conducted have shown that a centrifugal hydro-power system could attain ideal renewable energy densities in the range of 25-100 kJ/kg-H2O, depending on how much fluid pressure that could be withheld. When compared to energy densities in the range of 2-10 kJ/kg- H2O, attainable at present in gravitational hydro power systems, they are regarded as very high. Centrifugal hydro-power plants utilizing such an energy density range would be able to generate millions of mega watts of very cheap electricity to meet the ever increasing power needs of mankind.
