Hi all, I just looked at a thread involving a wind turbine on a car or something of that sort and I have a similar idea... but it does not involve a car. It is similar in the aspect of something creates energy , and you add something else to it to get more energy, but I'm not sure if the system would be more efficient. The idea: A wind turbine rotates which rotates a shaft, which is conected to the generator. (typical) Now what if small rods were embedded into the rotating shaft in the outward normal direction, lets say 3 rods on one plane, separated by 120 degrees. Now if pvdf's or piezoelectric strips were added to an outer housing, such that these strips were deflected by the rotating rods, how would it effect the efficiency of the system? Of course, these strips will add friction, but most of the time they are very very thin, and also smooth. They are easily deflected, but at higher Rpm's im sure more of an effect would be seen. I think decent voltage can be aqcuired through these pvdf's but compaired to the generator I think it is minimal. You would need a lot of these strips in order to get a noticable difference. Im not normally apt to sharing ideas of this nature on forums due to a fear of someone stealing my idea, but I dont plan on doing anything with this idea in the near future. (got other stuff on my plate) but if someone developed this it would be really neat. I would like to see how it would effect the efficiency of the wind turbine.
