"Blue Blade" Rotor Blades

High-tech carbon fiber rotor blades
Made of 100% Carbon-Fiber material – CFRP
Hand laminated. By using High–Tensile carbon fibers in hand laminated application with epoxy-resin the blades get extremely resistant
Wind channel optimized
Ultra low noise emissions
Balanced for low vibrations
Outstanding strength to weight ratio
Successfully tested according to DIN EN 61400-2 at hurricane speed 122km / h (5480 rpm, with almost speed of sound at the blade tips)


How Quiet is the Silent Wind Generator?

"As for the sound, we had gusts up to 40+ mph the night we installed it (got a 2 minute break from the gusts to get it up) and she was flying! There was very little noise as well. I have heard a few small wind turbines and the sounds they make are horrendous! But this blue bladed bird was very silent except for a small swoosh at the high speeds. The wind made more noise howling than the turbine. Out boat was being healed over close to 20 degrees at times from the strong wind. Also the automatic brake came on 3 or 4 times last night as well. We never noticed when the brake came on except for a small red light on the control box."
