Question
Dear Prof Steve

http://www.amazon.in/s/?ie=UTF8&keywords=table+fan&tag=googinhydr1-21&index=aps&

http://shop.bajajelectricals.com/Table-Fan-c-51.aspx

Is it possible to re engineer Table Fan design where the Table Fan can rotate in all directions i.e. 360 degree rotation ?.

If we have a Mirror Blades on the Opposite side, maybe it is possible ?. We will require one more electric motor for this construction ?. i.e. Two motors.

Thanks & Regards,
Prashant S Akerkar

Answer
Hello Prashant,

Certainly it could be done with 2 motors. But it could also be done with a more complex system of gears. It would probably be cheaper to buy 2 fans. And if you do a search for [360 degree fan] you will find that Honeywell (and others) already has one that blows upward and then uses a deflector to produce the affect.

I hope this helps,
Steve

Expertise

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.

Experience

I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
