Title: Qin Gang's Tumbling Routine
Post by: TechStuf on October 21, 2008, 09:24:28 PM
Ok, so we have here this Qin Gang fellow who 'tumbles' upon the following idea and reduces it to practice.  Bravo!


http://freelights.co.uk/how.html


A hard man to get ahold of it seems, as I've attempted to contact him on several occasions over the last few years, with no response.  I can certainly understand his apparent 'tight lippedness'.


The video is impressive, at least to me.  Leaves me with all sorts of thoughts about overcoming back EMF, leverage over time, etc.....


Of course, Mr. Gang couldn't possibly have discovered a simple alternative to exotic superconducting materials could he?


The fact that the spoke mounted 'inciter' magnet is situated far enough away from the coil to avoid appreciable EM braking yet close enough to effectively interact with the 'tumbling' magnet's flux field is probably of no importance.....


Or is it?

Tech seems like there would be a gate to break thru?

Hi TS,

It is sure there is a certain drag between the magnets as they pass by each other but the mass of the wheel is so much bigger than that of the magnets that this huge difference make a real "flywheel" effect, almost making the drag negligible.

However I think you may question also the drag by normal Lenz law when induction happens and the lights get on, right?

Well, the explanation is in his using LEDs...    You surely know LEDs need some Volts difference to give out light, depending on their color too.  (Red LEDs have 1.7-2V,  white LEDs have 3-3.4V forward voltage drop).
And he surely connects LEDs in series (and in parallel too) and when two red LEDs are in series connection, there will be NO current flow through the coil (hence no Lenz) till the induced PEAK voltage reaches or exceeds at least 2 x 1.7V !   This makes a huge difference in the operation compared to the case of using normal incandescent light bulbs which would be always loading the coil hence would cause a much bigger Lenz drag!

Elsewhere in his web pages he recommends 5mm mounting distance between the passing magnets and probably this gives an induced voltage of about 7V and 25mA current pulses he claims in the Q & A page.

Maybe these facts answer your question(s)?

@ Ramset,

Consider the video to be a macro example of a micro effect, run a magnet across an induction coil, and essentially you have tumbled myriad nano magnets into giving up the juice at cost.  Qin Gang hasn't even scratched the service....as far as he can tell.


Or at least, will tell.


What do Mr. Gang, Johnson, Kundel, Perendev, etc. share in common.....besides the obvious penchant for approaching the problem at oblique angles?


I would post some video, but I'm on my 3rd motherboard and 2nd hard drive in just the last few months.


I've inadvertently stepped on a few steel toes in my time.


Just sharing possibilities is all.

Yes that lenz certainly can be a drag!


Force coupling the wheel work of creation was never intended to be easy.

Hi TS,

I forgot to include another fact which can make drag also reduce:  the answer is still using LEDs...

LEDs are basically diodes and able to conduct current in one (forward) direction so say if some groups of LEDs flash up during  the positive half wave of one induced peak voltage periode, then this same group of LEDs will not load the coil in the negative half wave of the same induced peak voltage periode, ok?

By the way, what would you ask from Mr Gang?

I actually googled 'periode'!   :-[  (Always ready to learn)

I've simply asked various questions....basically wondering if he has noticed or exploited potential areas for efficiency increase.

Why.  Do you see any, perhaps? 


Areas for efficiency increase, I mean.

Hi TS,

Sorry for the typo, I meant period and should have used the word cycle instead. English is second language for me.

Of course I meant technical questions  :)  and possible areas for efficiency increase may include the shape of the magnets and also the shape of the coil.

Well, we must admit, the word "periode" sounds plausible in the hyper-morpholigical language that is 'English'.  Google it in a month or two, it'll probably be real by then!


I like your ideas....coil and magnet shapes.


There's something about that tumbling sequence though......


Something.
