Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Quotecan somebody tell me why the heat seems to produce more voltage
My best guess is expansion of the copper lowering the resistance. I think some type of thermal conductivity is also involved.   

Quoteand would more voltage make for a stronger magnetic field
I would say in general yes but the amount of current and frequency come into play.
With spark gaps a low voltage spark has a more intense magnetic field than a high voltage spark gap.

Its what I don't know that's a problem!

Iota - that was such a sweet link.  I've seen this before but here it's really well presented.  Many thanks.

Guys,  just something I've been considering.  Someone gave a link to a youtube number that was, effectively, a replication of laser's rig - but with one reed switch.  I've lost that link.  That guy had a far faster spin - and I couldn't understand his language so have no idea if he used moisture on the coil - or not.  Would be awfully grateful if someone could recover that link again and perhaps explain the test parameters he used. 

Laser's rig definitely has the rotor turning in one direction.  He explains this as a result of the push/pull synchronised emf from the coil.  The point is this.  As the rotor is only inclined to turn in one direction then there has to be some moment when the magnet is first attracted to the EMF and then that same magnet repelled - in short order.  If it was relying on repelling the second approaching magnet then effectively it would act as a brake to that spin.  In other words the rotor needs to be frequency dependent and dependent on those switches working in antiphase.  Begs all kinds of correspondences to the size of the rotor to get exact positioning of the magnets to line up correctly in phase with the switches.  Or does the switch determine the frequency and provided there's some spatial separation of the magnets then they 'fall in'?  In any event.  I can see that it would definitely be preferable to work off laser's actual sizes to keep some correspondence in these ratios.  I'll check laser's video again and see if I can find a size.  Else, laser, if you're reading here.  Could you please give an approximate diameter to that disc?  I'd be obliged.

Regarding the use of water.  I've asked a couple of chemists to comment.  Not yet heard from both but from the one I've been told that it's probably a battery.  I'm still of the opinion that water is simply a preferred medium for flux.  Water provides a very smooth field.  For instance I've heard it said that a bath of water is so smooth it could be argued that it's a single molecule.  Effectively therefore water would offer less resistance to flux than the rest of our atomosphere with its multiple disassociated molecules and atoms which would otherwise be the only medium through which it would pass.  I question that there is any actual electrolytic process going on.  Else we'd surely be aware of an accelerated drying process as those molecules disassemble. 

If it's simply required for this - for clearing a path, so to speak, for the flux - or for strengthening the flux fields - then we're still on line for OU.  Effectively it would then simply be a third element in that construct.  And it could definitely be structured that the moisture is retained in that environment on a relatively 'permanent' basis.  One would simply need to encase the rig in a plastic bubble of sorts and seal the ends against the coil - I would have thought?  The Laser generator - would then be just that.  NOT a battery. 

The only question I still have - actually there are loads.  I'll start that again.  One question I still have is this.  Are the collapsing fields the result of an interaction with only those three elements in phase with the switch - or does it also require some subtle interaction of the magnets on the rotor itself - to keep the inductive fields changing?  I know laser uses strong magnets and I very much doubt that any of that material will be isolated from the influence of those moving fields.  But there's a series of really complex events going on.  I agree with Iota.  It would be nice to get this illustrated in animation.

Rosemary

Laser's rig is a simple motor. As a magnet activates the first reed switch, current flows through the windings of the coil. This creates a magnetic field which attracts the magnet towards the pole. As the magnet passes by the pole, the first reed switch opens up and the field collapses. No more attracting force.
Somewhere around this time the second reed switch closes. This sends current in the opposite direction through the coil, which then creates an opposite polarity magnetic field at the pole, which in turn pushes the magnet away from the pole.
Rotor speed is determined by friction (air and mechanical) and counter emf created in the coil by the passing magnet. The rotor could also turn in either direction. The reed switches would have to be moved, but either direction would work.
Laser's rotor is also turning much faster than it appears in the video. The frame rate of his camera synchronizing with the speed of the rotor makes it appear to move slowly.
I hope this helps clarify things a bit.

Cheers,

Ted

Ted:

I believe you are exactly correct. 

I was also thinking that the same thing might be accomplished using a small transistor, say a 2n3904, and a single coil near the rotor ala Bedini.  Sort of a solid state Stubblefield coil.  Of course, you would have to have the output to fire the transistor at or above its threshold but this should not be a problem.  I was getting 1.32 volts at 5 mA's on my second Stubblefield coil attempt.  More than enough to do the job I believe.
