    Hi every one i have made a teaching aids for science like a project on sources of energy in which i have made a bio gas plant,hydroelectricity plant and a solar garage.
    The good thing is that i won the first prize for the project and also the second prize for the best teaching aid. i also got selected for the zonal level so can some one suggest me some more idea to add in this project some kind of sensors or some thing else
    thx in advance :D

    Well buddy...It seems you are doing very well yourself.

    Since you have made gas plants, I presume you must have used sensors in it.

    Wind power generation?

    You could add pumped air/water energy storage for ride through capability during low wind/no sun times.

    OK. The main part, with the magnets, rotor, commutator, brushes, and black pulley, is a commercial physics lab demo of a DC motor. The pulley is used to have the motor drive something.

    I added a turbine rotor from a squirrel-cage fan, coupled it to the motor with an pulley glued on top of it. An air line (quick-disconnect coupling) supplies air though the valve (knob) and nozzle to drive the turbine. Hand held optical tachometers measure the speed of rotation and they relate that to the motor's (now a generator) output.

    Is seemed so obvious to me. ;)
