Tocardo International T1 Turbine
The Tocardo T-1 turbine generates clean energy from tidal currents. The T-1 has power outputs from 50 kW to100 kW. The turbines are made to last with very minimal maintenance. The design lifetime is at least 20 years. The T-1 turbine power generation commences at flow speeds of 0.4 m/s and peaks at 4.5 m/s producing 100 kW. At flow speeds above 4.5 m/s the turbine enters ‘stall mode’ which is a control strategy used to prevent overloading of the turbine. T-1 turbines are capable of being operational up to 6.8 m/s, and can safely withstand 9.0 m/s speeds (survival). Another unique (and patented) feature is the smart reverse system which enables the turbine to operate in opposite tidal flows. Instead of using maintenance sensitive yawning systems which turns the entire turbine, we only let the rotor blades flip. The whole system is powered only by the force of the water (passive pitch).
