Water Wheel In GreenPoint Editorial Image

A walk through the GreenPoint park in Cape Town South Africa. Water Wheel telling the history of water in CapeTown The use of water to generate power is demonstrated at Green Point Urban Park with a turbine and a water wheel. The water wheel, which is 3.5m in diameter, makes use of about 20l/second of water coming from the Main Spring Stadsfontein in Oranjezicht to generate around 0.2kW of power. As this water fills the buckets on the water wheel, the extra weight on one side turns the wheel and drive shaft thus generating electricity. The Main Spring is the original source of water that enabled Cape Town to be established in 1652. The reliable flow from these springs was identified by mariners, and supported those who lived here many centuries ago. The demonstration of renewable energy at Green Point also includes taking the 500kPa pressure and flow of water 20l/second in the pipeline bringing the water from the spring to Green Point Common through a water turbine prior to discharge over the water wheel.
