Try making the rotors rigid, or adding space between the front and back of the rotors by placing the cork in the middle of the windmill.<BR/><BR/><A HREF="http://www.lkl.ac.uk/projects/vesel/index.php?q=node/28" REL="nofollow">Power Engineer Expert Comment</A><BR/>The role of the windmill is to transfer the energy stored in the wind to the energy stored in the inertia of the rotating windmill. This is done<BR/>by the careful design of the blades, their size and pitch to minimise the "pushing back" effect and maximise the rotation.xhttps://www.blogger.com/profile/06092961067652136976noreply@blogger.comtag:blogger.com,1999:blog-6625817847440266169.post-72213215738398287412008-06-13T15:12:00.000+01:002008-06-13T15:12:00.000+01:00This comment has been removed by the author.xhttps://www.blogger.com/profile/06092961067652136976noreply@blogger.com
