STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[Omnibus]

@exhiloest,

Steorn has’t yet shown proof for overunity. However, Steorn has shown practical elimination of back emf. How is that conventional?

I haven’t even seen yet proof that even the negligible back emf is due to the presence of the rotor. It very well may be that that’s due to imperfections in the making of the coil and will show itself even in absence of rotor. @k4zep may help us easily in clarifying this -- show the osciloscope traces i absence of rotor and see iif there's the same slight back emf.

So, suppose that that’s the case â€" both in absence and in presence of rotor oscilloscope traces remain the same â€" then that would be the ultimate proof for OU. No Eout/Ein measurement needed, no calorimetry etc. If traces remain the same then a supposed 100% energy balance for the coil in absence of rotor would have retained its 100% energy balance when rotor is present but when rotor in present there will be additional rotational energy coming “out of nothing”.

Hi ALL,

On this page #33, a whole pile of interesting questions that I will answer with very short answers.  I am not trying to ignore any question but time spent at the keyboard is time away from the bench and I have spent a LOT of time at the keyboard over the last few days.

Respectfully
Ben

Great stuff in this thread guys!  Thanks to all of you who have rolled up your sleeves on this one and got your hands dirty!  I'm just getting caught up to speed with this thread, forgive me if someone has pointed out what I'm about to ask already, but I missed it if so.  I agree, it is impressive with the reduction of BEMF with this type of toroid power coil setup, but it leaves me with a big question.  Is it necessary?  What I mean is this...  It appears mostly that what is being done is powering a motor with no BEMF, and recovering as much from the inductance as possible.  (I'm ignoring the generator part, as it is a seperate animal than I am referring to.)  If this is true, then has anyone made a simple attraction motor?  Replacing the magnets on the rotor with Iron slugs, would easily remove all the BEMF in the system.  Pulse the power coil before the slug reaches the coil to attract it in.  Cut the power just before dead center, and the field collapses, still pulling the rotor into the coil.  When it reaches the center, the power is totally off and the field completely collapsed so the rotor floats right on by with no resistance, and I believe no eddy currents.  No BEMF at all.

Yes, that would work but power very limited.  That advantage of the "no BEMF" is the use of magnets in the rotor and increased torque

Now, it is possible that using the toroid power coil with rotor magnets concept produces more mechanical power, with less energy wasted...  But I'm not sure that it would.

I do not know yet either, time will tell!

  So that's my question here, has anyone tested an attraction motor, and how would you compare it to the orbo design?  Not to mention, the demo runs on 1.2 volts.  That does seem a bit interesting.

Yes, I have built several, nothing special there at all

The point here is this, while the motor concept is intrigueing, I am not sure it is more efficient than just an attraction motor that has already been invented long ago. Granted, I have not seen an attraction motor go to OU, just simply no BEMF.

Correct  I think the magic is in the generator side of this device.  Not that the motor is bad, just that I think the second part of Orbo is key. Only problem is, I see nothing out of the ordinary on the generator side.  At least as far as I can tell, from the pictures, the pickup coils appear to be regular nylon core coils.

No BEMF in generator would be just as advantagous BUT resistive losses in generator would limit any generator to less than OU so it would seem paramount that the motor is OU

@k4zep,

Great work!  I wonder if you could try something simple.  Oh, forgot to say welcome aboard.  Have tried magnetic static bias and does NOT seem to increase the speed, need to do more test though.  Could you try putting a permanent magnet on the opposite side of your toroid?  I am just curious if maybe by partially saturating that core with a permanent field of the same polarity the current you plan to push into it is going to create, maybe you could get better efficiency by not drawing as much current to bias that toroid...  As long as the permanent magnet is not strong enough to saturate it to much, I don't think it will effect the attraction the rotor has to the core much if any.  Just a thought, I know it's not in the demo, but maybe it's part of what they will show in January.

Again, bias in the core might be of a help, I just cant demonstrate it right now.
