The Saphonian › Tests and results
The tests we have done with our various prototypes (V.1 and V.2) have confirmed and validated most of our theoretical assumptions / projections. They also proved that the Saphonian is by far more efficient than a comparable bladed turbines and that its Performance Coefficient (Cp) is above Betz Limit (59.3%). The Saphonian efficiency level stands at the outstanding level and its generated power is increasing exponentially with the wind speed. The Saphonian has no rated wind speed and the synchronization of its motion with the different wind speeds enables it to remain at its efficiency optimum level at any wind speed.
Giving its bladeless design, the Saphonian has no tip speed ratio (ƛ).
