ESAW Windmill (EEC-10214)

we have required an energy, which remains last and present at earth in unlimited amount. As fossil fuels becomes more expensive and we are very well understand the harmful effects on the environment and we have required energy, which overcome all these problems. The one solution is wind energy. The students can study speed/voltage relationship, blade number and arrangement, maximum RPM's and voltage, drive shaft ratio and wind speed effects on placing the instrument in front of a fan or in natural wind. A rubber belt drives motor on rotating the pulley fitted with shaft. The No. of wanes in instrument can be changed as per requirement by just fixing these inside the slots given in the cylindrical wooden block.
