Normally a hydro turbine requires a pressure head of several meters or must be in a fast current to develop power. Power plants kill huge proportions of fish through their cooling systems. This is not the case with the Brayfoil turbine.
With a high lift to drag ratio, the drag is minimal to power produced, and this energy form is likely to be the most environmentally friendly source yet discovered. The currents flow all year round and can be a good source of base power, which is different from most other environmentally sourced renewable energy, such as wind or solar.
Totally invisible, non-invasive to marine life, very low maintenance and completely pollution free, this energy form appears to be the answer to South Africa’s power problem.
Fish strike and resultant high fish mortality rates from existing turbine types prevent many turbine installations in estuaries and tidal applications. Unlike most turbines in water, this turbine turns slowly and never exceeds the speed of flow, making fish mortality very unlikely.
There is far more power available from water than air, and this morphing wing has the ability to create lift from very slow moving currents.
The hydro turbine applications of the morphing wing are limitless.
