City of Johannesburg mayor Parks Tau announced in his 2015 State of the City address that Joburg will harness energy from water flowing through its citywide pipe system using in-pipe turbines.
Electricity using water pipes made headlines earlier this year after a 200kW system installed in a water pipeline in Oregon came online.
The system in Oregon uses the LucidPipe Power System – which works by taking conventional water pipes and replacing them with Lucid Energy’s pipes. The new pipes are fitted with turbines, and as water passes through the pipes the turbines spin and generate electricity.
“As velocities increase, power production increases. Due to the lift-based design of the LucidPipe turbine, the system generates power across a very wide range of velocities,” said Lucid Power.
The company said the design of the turbine does not interrupt water flow and allows for power generation at low pressure levels.
“One mile of 42-inch diameter pipeline could produce as much as 3 megawatts or more of electricity.”
How it worksThe LucidPipe Power System uses the flow of water inside a water pipeline to spin turbines that produce electricity.
The hydrodynamic turbine is designed to maximize efficiency and power generation while limiting the onset of cavitation. As velocities increase, power production increases.
