N-Machine updates?
« on: August 22, 2006, 07:09:09 PM »
Hi,

Does anyone know the status of the N-Machine?

About 20 years ago I visited Bruce in Santa Barbara, CA, USA.  It was very impressive.

Last I heard Bruce passed on.  Has Tewari or someone else done anything with this technology?

Thanks,
Paul Lowrance

Thanks for the link!  What an elaborate looking machine with 173 magnets.  I'll have to read up on it.

Regards,
Paul

Hi Paul,

I've been reading up on N machines (Faraday discs) alot lately. I've read all about the stardrivedevice dynamo disc as mentioned in the previous post. Also i've read studied tewari's space generator and the Trombly-Kahn generator which is apparently used by the US navy in submarines. So i think the thing is working but hard to reproduce if you haven't got access to the rights tools and materials. I think the biggest problems wiuth the faraday disc are the low voltage/high current which are hard to convert to a usable level and the pickup brushes (liquid metal is best but even harder to construct).
I may have some ideas on improving the design at these points and would like to discuss them with you if you are interested.

Regards Dutchy

Hi Dutchy,

Yes, others and I at this forum are very interested in hearing your ideas.

I agree the brushes are inefficient. I recall seeing one of Bruce's $100,000+ machines that had mercury contacts. Mercury contacts are efficient but expensive.

As you said, the current is extremely high and difficult to convert.  I'm wondering if there's a way to do it now with modern mosfets. Perhaps paralleling the mosfets to create some form of a switching transformer.

The thing I like best about Bruce's work is the spinning balls and other spinning experiments. There's something about spinning objects.  Bruce demonstrated how inertia changed.  I calculated that the outer part of Bruce's $100K machine to experience 9000 G forces do to spin.  If we look at nature we see that everything spins from Galaxies to solar systems to moons to planets to atoms to even electrons and protons.

@Paul,

HI again. I'll try to explain my thoughts regarding the N-machine improvements. My idea is to address the two main drawbacks of the original faraday disc. They are as said before, the very low output voltage and the pickup brushes/contacts.
To change this I imagine foloowing changes to the concept:

1) replace the copper rotor disc with a spirally wound (bifilar/tesla pancake) coil of the same size. This will increase the voltage I guess because of the tremendous increase in length of the conductor. The bifilar design will increase the enrgy capacity of the coil. Because of the pancake design there will not be much counterflux returning to the stator. The "rotor" can now become static (see 2) and the pickup brushes are no longer needed.

2) replace the permanent magnets with an array of hildenbrand type valves on both sides of the "rotor" (it is no longer a rotor...). By switching the valves on and off they beam the magnetic flux through the spiral core "former rotor". Since there is no counterflux interacting with the valves they can be switched with very low power.

What do you all think of these thoughts? Does it make sense? Do you need more explanation?

Regards Dutchy

Hi Dutchy,

Sounds good except one thing will not work ->

1) replace the copper rotor disc with a spirally wound (bifilar/tesla pancake) coil of the same size. This will increase the voltage I guess because of the tremendous increase in length of the conductor. The bifilar design will increase the enrgy capacity of the coil. Because of the pancake design there will not be much counterflux returning to the stator. The "rotor" can now become static (see 2) and the pickup brushes are no longer needed.
The induced voltage on a Faraday or N-machine is inward. There is no sideways induced voltages. So the spiral will do nothing but increase the internal resistance. :-)


2) replace the permanent magnets with an array of hildenbrand type valves on both sides of the "rotor" (it is no longer a rotor...). By switching the valves on and off they beam the magnetic flux through the spiral core "former rotor". Since there is no counterflux interacting with the valves they can be switched with very low power.
Wow, that's very interesting! I've read about Jack Hildenbran's device but really don't know the details such as the valve. Sounds great though and Jack's thread is getting a lot of traffic.

Thanks for info.
Paul

Hi Paul

I think the polarity can be reversed by changing direction or magnetic fields.  Tesla had his version patent number 406968.  This would be the one to build.  It doubles the voltage and solves the high speed brush problem.

http://www.keelynet.com/tesla/00406968.pdf

I think Depalma and others missed this patent.  I never saw it mentioned or referenced in their articles.

Hi tishatang,

Thanks for link. Tesla sure got around. :)  He was amazing!

Hello tishatang
Thank you for the link to the Tesla patent. I have an interest in the unipolar generator and Faraday's induction dynamo. This Tesla dynamo appears to be two induction dynamos with the rotors joined by a conductive belt. However, the terminals are both the center shaft of the two "generating conductors". Since they are both turning in the same direction (either CW or CCW) doesn't this mean that the two terminals are either both positive or both negative?

Hi Tropes

The magnetic field of the second disc is reversed causing the second axle brush to be opposite from the first.

Here is another good link.  Explore the whole amasci.com site for mind bending ideas.  Bill Beaty is a genius and yet, practical.

Click on the "two N-machines merged".

http://amasci.com/freenrg/n-mach.html

Here you can see the reversed magnetic fields.  This is even simpler than Teslas patent.  However, I think the two discs of Beaty's design need to be connected together only at their extremes edges.  Otherwise, I feel his coupling will short out the current?

Bill Beaty has done some impressive work. Thanks for the links. I have uploaded an image to http://theowlnest.com/kickbypage.html . If you click on " Dual C-generator" you will see my version of Tasla's dynamo-electric machine. In your opinion, would there be a current flowing between the two terminals when the iron disks are rotating?

Tropes

I looked at your design and I have the following comments.

Yes, there should be current flowing as far as I can tell.

However, I suggest the following:

The rotors should be non magnetic.  Iron will attract to the magnets.  Use copper or aluminum.

The connector looks like the same as a brush contact.  This is a source of loss because it is contacting the high linear speed of the rotor.

Since you are driving the rotors with a cog gear arrangement, why dont you just do away with the connector and use the input driving gear in its place.  You could use a large diameter gear in between the outer rotors, the rotors having gear cut edges, and by using conductive lubricants use the driving gear as the connector between the rotors.  The driving gear will have to be insulated from the shaft.

Also, to simplify construction, if I recall correctly, the rotor does not have to be moving separate from the magnetic fields.  You could just glue the magnets to the rotor and rotate them together as a unit.  You would have to experiment to see if this is true.

Hope this helps

Thank you for taking the time. In his patent description, Tesla suggests either copper, brass or iron for the rotors. Maybe a combination of two metals; one for each rotor. The idea of gluing the magnets to the rotor is intreguing. That would certainly simplify the generator. I read some theory that the magnetic field remains stationary while the sandwiched disk and the magnet material rotates. As for the connector, it takes much less machining to have brushes rather than a set of gears when constructing a prototype. However, I have made a change to my drawing.
Thanks again from Canada
