Solution Overview
Problem
Traditional water supply systems waste excess water pressure energy due to higher pressures than necessary for delivery, necessitating a method to harness this energy for alternative uses.
Innovation Solution
A hydroelectric turbine system is integrated with water supplies to convert excess pressure into electricity using a Tesla turbine design with bladeless discs and a magnetic shaft coupler, generating DC electricity through fluid torque transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If excess water pressure is reduced to standard delivery pressure, then water delivery service is ensured, but energy is wasted
Solution Approach 1:
The patent converts the harmful waste of excess water pressure energy into a beneficial energy source by installing a turbine system that captures this pressure differential. The turbine is positioned between the high-pressure incoming water supply and the low-pressure distribution system, transforming the previously wasted pressure energy into electrical energy while still delivering adequate water pressure to consumers.
Solution Approach 2:
The turbine system acts as an intermediary device between the high-pressure water supply source and the low-pressure distribution network. It mediates the pressure differential by extracting energy from the flowing water through its blades, converting mechanical energy from the water flow into electrical energy, and then releasing the water at reduced pressure to the distribution system.
2Loss of energy
If a turbine system is installed to capture excess pressure energy, then energy recovery is achieved, but device complexity increases
Solution Approach 1:
The turbine system is designed to serve multiple functions simultaneously: it acts as an energy generation device, a pressure reduction device, and a flow control device. By integrating these functions into a single compact unit, the patent reduces the need for separate equipment and simplifies the overall system architecture despite the complexity of the turbine mechanism itself.
Solution Approach 2:
The turbine system is designed to operate automatically using the natural pressure differential of the incoming water supply. The water flow itself provides the driving force for the turbine blades, eliminating the need for external power sources or complex control systems. The system self-regulates based on the pressure differential between inlet and outlet.

AI summary
Systems and methods for generating electricity from a hydroelectric turbine are provided. In one aspect, the system employs a Tesla turbine to rotate a drive shaft, the drive shaft providing torque to operate an electrical generator. The incoming fluid flow that operates the Tesla turbine enters a hollow portion of the drive shaft and exists the system as an exhaust flow. The system may operate from standard water supplies provided to a residence or business, thereby reclaiming excess water pressure energy.
