Coreless/ Wireless Induction exp

[Localjoe]

Well this is my first post here, I've been reading here for a while though, amazing members you guys have.  Anyways after reading the mit article the other day , i forced myself to start exp with with the idea and wanted to build a conceptual base for others and my self to collaborate on.  From what I grasp, and I could well be wrong theres a few different things at hand here that are easy to mix up, we all know how transformers work or a basic concept,  Theres wire coils and feromagnetic core. Inductance comes into play and power can be stepped up or down or isolated ect., Then we have the well known tooth brush charging base concept/ inefficient and could be not safe. So the transformer is an example with a "core" The toothbrush without. Power transfer still happens in both scenario's but the latter being much less efficient.  Mit's recent article described two large hoops, spiral, large gauge wire it seems one with ac mains and the other with a resistive load.  Now if the hoops were both the same physical dimensions i suppose its a sort of resonance if its darn near exact so mabey its acting as a wave guide, dont really know just a guess, this last sentence was just an add moment, i didnt really use my stuff in the same way for my exp. So in my exp, I took a foot and a half peice of 16gauge stranded coated wire, scrap from work and formed it in an inward sprial about 3 turns. No rocket science there, I connected the center end that i wound inward to the - on my rs 4 d battery pack holder 6v on the other end here I could connect it directly to the positive. Next I take my small coil probably 40 turns of 22g magnet wire enamled, picture the thing that spins in the diy dc motor demonstrator,  those leads are connected to a led's +  side touching either coil lead, oppisite coil lead to positive lead on multimeter, neg lead to other end of led. If i move the little coil around even 2, 3 feet above the "primary" I get a small spike on my meter probably in the range of 25 mv dc. i get this i move the top cut the lines and a little power is transfered. So i realize the difference between a dc electromagnet and an ac electromagnet and decide hmm need spark gap... dont have spark gap.... hmmm homopolar motor . so on the big spiral i take the positive lead off and run it in series/hold it on the flat side of another d battery and grab my screw and a couple neymodum magnets stick them on the bottom of the screw and i use the end of the big sprial I was directly connected to before to act as a brush "just to test" to make the little skrew magnet homopolar thing spin. Now i gathered that tesla used a spark gap to make his hi freq's or oscillations, so i figured that that little magnet thing that spins would do the same thing, it goes like 3000 rpm and it did!  I was able to get at least a 1.5 v constant on the meter while the motor was spinningat top speed, and the voltage was directly proportional to the speed the magnet screw thing spins.. I need to make a nice brush armature setup but i wanted someone else to test this too and tell me what they thought.  I know this sounds a bit weird but it works and it kinda makes sense to me, so i figured why bother my girlfriend for a half hr excited explanation when i could tell you guys.  Please critizie help i dont get offended i jsut wanted to share and for all i know someone has someting way cooler.  After i understand the theroy behind this it might be cool to then understand how tesla coils transmit power inductively through the oscilations in their secondaries, and the concept of giving an adaquet load for a given input.

Hmmmm...

Interesting experiment! I'm sure that if you post more information about what you saw and perhaps a diagram or schematic, others will replicate your results... and based on what you're saying, you should probably look at coupling this concept with a high rpm Newman motor. If indeed its the speed that determines the output voltage, I'm sure a high RPM concept will be presented in this thread soon.

Good luck and keep it up,

         Thanks for reading, normally I would post pics right away but I was tired last night and had to work the grind today. Anyways I'm going to go take some now. Well and eat of course .. its dinner hr

Heres some pics only thing i dont have a photo of is the skrew with the magnet and the 5 d battery lost it somewhere on my other bench... find it soon but anyone who has seen the generic youtube homopolar clip can envision the same thing with the + leg of the d 4 pack going to the neg of the battery with the skrew magnet motor and brushed with the outer leg of the spiral, have it soon, thanks to all who have read so far.

my attempt at a "paint"diagram sorry for the crudeness
