Ceiling Fan Challenge

If you want us to do your homework for you at least make it look like something other than homework!!

stop talking start thinking...

ha ha ha..

if tom is going to use a dynamo which does not going to change the speed of the fan appreciable in any way....then i would say tom is not a technical dunce

Sure, I will bite (to your baited homework/over-unity/general interest question).

You are saying that the speed of the fan remains the same with the dynamo mechanically coupled to the ceiling fan, what about the power required by the ceiling fan to continue rotating at the same speed, do you think it stays the same or increases?

Here are three elementary motor/generator electromagnetic theory questions in answer to your question "could Tom save energy this way"

1. What is the mechanical load introduced by the dynamo with the dynamo electrically open circuit?

2. What is the mechanical load introduced by the dynamo with the dynamo electrically connected to an electrical load?

3. Why is the mechanical load introduced by the dynamo directly related to the amount of electrical power produced by the dynamo?

As for the answer "could tom save some energy from it or not", the answer is never.

For a full explanation of electromagnetic theory and over-unity see previous threads on CR4 and Wikipedia.

i can prove tom is not a dunce........can you give a proof????????

State your proof and at least get everyone to have a go at "proof reading your answers"

We're waiting!

Our proof is the law of conservation of energy. If you can prove it wrong, you should be rich very quickly!

I think you have discovered free energy, or at least, perpetual motion here. Suppose the dynamo takes one xxth of the energy from the fan, if you use enough of these, allowing for less than perfect efficiency, you could extract enough energy to drive the fan! Add some more and you have a surplus to run a light so you can watch this happening.

Your fortune is made. I wish that I had thought of that idea first?

As dumb as this answer sounds, it shows you how to answer your own question.

is any one there to disagree with passingtongreen's comments?????? ................ take the challenge

Doubtful, we're all too busy either wishing you would just go away, or laughing.

lol

"...could tom save some energy from it"...Depends on what you mean by "save"-- sure he could save some of it by charging a battery. He still pays for it and it costs more than would otherwise be required.

" is he wasting his time....?" Only if he is intelligent. On the other hand, who can judge the value of a fool's time on this planet?

Of course if Tom was to disconnect his dynamo from the fan and hang it below the fan with small windmill blades attached.........

Even with the windmill, if the dynamo extracts energy from the airstream, it will increase the current draw by the fan, and the increased power required by the fan will be significantly greater than the power extracted by the dynamo.

As JOAT said, the answer is NEVER!

Where's Del... sounds like we may have invented a new cat toy! We can even add feathers to the windmill blades, or a catnip dispenser... Oh yeah!

No, but with a bit of work he could turn the ceiling fan into a high speed salami slicer.

If he's tall he could turn it into a flowbee

If it means dynamo only then he can.

If it means the system then it is PMM.

If it is conencted only at the time of switch off then he can.

...

If he is planning to build a windmill generator, not using the fan as a motor, then it is negotiatable.

Otherwise he is wasting his time

I like this thread. This is one of the rare time s that people have not risen to his bait and answered (despite his barbs and prods ) Let us hope this continues.

The youngsters should think and find tha answers, not let others to think for them.

Let us hope this attitude continues. Give them sufficient to think, but answer should be from them.

That gives them power to think and also tomorrow they have to solve these problems for themselves.

This is how the Google Generation thinks for it self now.

Maybe he can use the dynamo to power his dipole transmitter.

I wonder if coating the fan blades with prop wash might improve the efficiency??

Bill

Only if you use the appropriate container for storing the prop wash prior to application.

Very true... I have heard that prop wash will oxidize a steel container over time, so glass or plastic would probably be best.

Bill

The prop wash may etch the glass jar, there by degrading its efficiency...
