Shorting coil gives back more power

[popolibero]

Yes i did thanks and i read all your tests its looks very interesting. I still haven't had time to watch your YT vids yet as the internet for me this last weekend was very slow and take forever to load so i was going to reply after i seen them. I have been getting a LOT of PM's lately so sorry if i cant answer them all but i do read them. I prefer them in public on relevant forum so i don't have to keep answering the same questions over and over unless of course its a really private matter.

Bolt, I think you must have confused me with someone else lol as I'm not sure what texts and vids you are referring to. My PM was called "wake up tool". I didn't post here as I didn't want to be off topic.

The coil in Magnacoasters setup is most important.The magnets used are also important, you must match the coil with the magnets used.When the single magnet on the gap side is close to the core should attract to the coil even if it is in repulsion because attraction to the core, then when power is applied should push that magnet away.If the coil is not right and powerful enough then it will not create enough gain when the power applied returns to zero.
Suggestion:
Make a coil with 2 layers of wire then continue making another 2 but only on half of the coil, on the side where you have the gap.This way you will get stronger field on that side where you need to cancel the magnet.
The coil does get hot after some time that's why Richard is using oil cooling.
I have been working on this setup since Richard posted his first results but still without having more than 1.7 -1.8 .
We need a bit more than 2 then we are in business.
I got best results with the mecanical setup not with the solid state.
Success,

@Romerouk,
Thanks for the explanation. I kind of see what you are talking about.
Just a suggestion. If you could use windows paint program to just draw blocks over lapping. This would make any explanation more clear then you can focus on specificity quicker. I tend to try to over mentalize and get the wrong idea. No different than most of us. 

I use Visio. That lets you then move items individually to accomodate any adjustmentment.

@l_ron,
Thanks for the zero crossing circuit.
I posted 555s because this is a predominant item in most inventories. Was just trying to accomodate quick prototyping at no monetary outlay.

I interpreted your response to the Falstad script as 'My bad'. I didn't take into account the complexity this might prove to most. I tend to shy away from simulators also but in this case it proved invaluable to expidite another version of your circuit.

Also when I mention the 'I' word I am not claiming ownership or plagerism. Never. I was only expressing effort to present an alternative solution even though it used more parts. My goal is always to get more out there quicker.

If anybody was offended I apologize.

Just a note on Bob Boyce.  Its my understanding after dissecting all the info i can find on it that the toroidal thing he uses is wired as a  3 phase transformer in essence driven by processor for control of very narrow PWM pulses, amplitude  and frequency control. The HF ferrite transformer is driven out of phase to create very high VARS and the cell sits in series with another inductor with a cap across it to make alike RF tuned circuit. This is basic RV technology.

Bob says the overall system from DC to gas has a COP around 3-5 typical. The only reason i mention this is because i seen reference to Bob's stuff having a COP > 1000 and this it not true.  So his devices puts on par with a good MEG but falls way short of Kapanadze COP 100 and the real TPU and VTA has a COP > 1000. Anything with a COP 5 or over should be capable of looping very easy.

Bolt, where do you get the figure of 5?  From what I've heard , or what's in the documents I've managed to scrounge up, indicates that Boyce's device could potentially be really high COP if done properly.  I'll go with a COP = 5 though since you seem to have more information than I do.

Although many people have produced COP 1.2 or 1.8 etc within well tuned Joule Thief's, Bedini wheels and chargers etc you cant loop till you get a COP 2 plus losses to loop it usually means in practice at least COP 2.5  and even then its twitchy as hell to get a motor/gen looped at low COP and will have no power to drive anything else other than barely keep itself going.

Thanks, this is great information.   


I'm trying to figure out how to do the Boyce TPU pulses and phase properly with microcontroller interrupts.  It's hard because on a 16Mhz/20Mhz Atmel the fastest you can interrupt is around 37ns.   But if you want phase control with resolution of 1-3ns then you have do calculate your phase correction over multiple frequency cycles (calculate pulse wave phase over multiple microcontroller interrupts).   

This is for a wave with around 1% duty cycle btw, so for example 500ns on and around 49.5us off.   I suppose actually , thinking about it now, that you could do this within a single interrupt cycle , but I need to start playing with Atmel assembler and my scope.
