New TPU build

[Nikola Tesla]

Does cause a little concern though doesn't it. A least there seems to be no affinity to lightning from the SM TPU.

Page 42:

Larger collectors have a much greater ability to collect and
dissipate more energy then the smaller ones.
However, if they turn into a bomb it will not make much
difference...
There is no such thing as a small lightning strike.

Page 46:

If the unit goes too far on frequency it may begin to convert too
much current and try to dissipate way too much voltage.
The multi strand wire will just burn up and open the circuit whereas the
heavy gage wire will continue to conduct until there will be the equivalent
of a lightning strike of the unit.
That of course ends the operation of the unit but can also prove to be
rather dramatic and also somewhat dangerous if you are in close
proximity to the power unit.

Thanks Loner

You're meltdown of the past sounds quite dramatic. There must have been a hell of a lot of power being disipated to create such a mess... does get you thinking.

I'll post photos and results as I proceed. I have now decided to build two similar units a la Boycie, but one with a toroidal transformer ferrite core and one with a copper core made simply from microbore copper piping. This way I can observe the differences these two cores make.

I've got to get hold of the toroidal transformer core, but have everything else.

However, I can't let this interfere with my love of Wimbledon, so the next few days I'll just be gathering the parts ready. The way Venus took apart the world No.1 Safina, was quite incredible. Big day for Britain's No.1 tomorrow! Murray vs Roddick... gonna be a good one!

@BEP

Just in case you read this, here is my vulgarization of the BEMF issue. lol

BEMF equals CEMF and are part of the process of saturating a coil. As power is applied to the coil, there is a counter force working against the inrush and this prevents the coil from being instantly saturated. It's like a coils' natural internal protection system saying to the energy source, "Feed me, but don't blow me away".

We should know that inductors (coils) discharge when they are disconnected whereas capacitors discharge when they are connected.

So when you disconnect the coil from the power source the field inside and around the coil collapses or recedes and there is a nice return discharge that is called Flyback, not BEMF or CEMF.

You cannot collect BEMF and CEMF since it is expended only during the inrush that happens when the coil is connected to a power or pulse source.

BEMF and CEMF are not the cause of drag or motor cogging either.

You CAN collect or recapture Flyback. It can even kill you if the coil is big enough.

Guys that say they are capturing the BEMF are actually capturing Flyback.

In any case BEMF is exacly that. When there is EMF applied, there is a reverse EMF applied also and that is why we call it Back EMF. You cannot apply a reverse EMF if there is no EMF. This only happens while the coil is connected. The coil can only collapse when it is disconnected at which time both the EMF and the BEMF are impossible to even exist.

We should actually just forget about BEMF and CEMF because there is nothing you can do with it. Many guys here know but they will not correct every member when they say BEMF simply because we would be spending all our days repeating the same thing.

Now if the above is totally wrong, this gives even more reason to then call the collapsing field of a disconnected coil something else other then BEMF and CEMF since these two are causing major misunderstandings. But for me Flyback is the best term for the juice we are all looking to capture.

PS: Some other thing about Flyback. Why is Flyback voltage so high? Could it be because while applied power to a coil meets the BEMF to slow it down, when the source is disconnected to produce Flyback, the Flyback energy does not encounter any counter force while it is receding or returning to the source. BANG. Otherwise we would have BEMF to counter the EMF and then CounterFlyback (CFB) to counter the Flyback (FB). Is this fun or what?

OK, for the record, I have managed to get hold of a toroidal transformer from a defunct 1400W stereo power amp.

A bit of a beast and very heavy. Will be unwinding the wire while I'm watching the tennis.

Tried to attach a photo, but I'm told that the file size is limited to just 300Kb... my photo is 0.98 Mb!!  This is going to be a bit restrictive.

Had to try to alter the resolution on my camera, by using the digital zoom, but got there in the end, this is at 245kb.

so i went for a digg last night found this picture


what about a jt to cause rotation and pump the colapse throught the collectors .. 

i bet it will work thanks to aluka for the pen art drawing

ist

i guess ill build 1 of thease ...    i will use pancake coils ...  i will start with 1 and 4 coils just like this dwg ...

i started a build useing this design ...   

55 " bifillar speeker wire ..  14ga  this will be a 3 turn pancake COLLECTOR COIL.....

so i soldered the 2 seprate ends as 1 wire... on the INSIDE OF THE COLLECTOR COIL

so in essience we have a MK2 collector style coil ...   it goes in and it comes back out  but ontop of each other unlike the toroide mk2 unit ...  still the same operation aplies ... the induced or squeezed collector runns 2 dirrections

OTTO'S TEST ..... sound good ?!?!?!?!   50 turns / control coil 200 per collector ... all 1 wire hummmmmmmmmmm

i have lots of 28 ga wire ...  maybe ill try that ...

50 turns of 28 ga is 82" with 2 6" leads ...

i knew i had those rings machined for a reason ......
