I want my 14 minutes back. There's no proof of anything unusual in that video.

1) He's got 18 9V Energizer batteries hooked in series, for 162V. Typical capacity of those is about 1 Ah; they should be able to provide about 100mA for ten hours without complaining. Total energy content is

E = IVt = 162 x (9V) x (1 Ah) x (3600 S/h) = 5.3 MJ

That's quite a respectable amount of energy, certainly enough to run his motor for a while.

The multimeter shows that they're providing at least 200mA, so their power output is at least

P = IV = (0.2A) x (162V) = 32.4W

which is enough to move his motor. Who gives a damn how much it weighs?! If it's got good bearings, all he has to do is overcome the power loss to friction to keep it spinning with no load.

2) It's hard to tell for sure but if he's got the voltmeter set at DC amps, it will certainly read negative on the backswing as current through the motor's coil inductors reverses. It just samples current every once in a while, not continuously, and when it happens on the backswing, it will temporarily read negative. This is of no importance at all and means nothing interesting. It's just an artifact of a digital voltmeter, which anyone who's used one knows. The purpose of flyback diodes is to protect things like batteries from the spikes when the inductor current switches.

....followed by

1) he turned it by hand to start it instead of using the batteries alone;

2) it clearly has little rolling resistance;

3) the ammeter was showing 4A to -0.4A, which suggests a larger power draw; averaged perhaps (1A) x (162V) = 162W = 0.2 hp, though I doubt that would be sustained, or needed, to run it. At 1A draw, the batteries could run it for about an hour;

4) the current surge at startup would in no way drain that much energy from the batteries. They have internal resistance to limit their current output capacity; besides, the lifetime of the initial current surge is less than a second, and they have 1Ah capacity, meaning that they could sustain a 60A surge for one minute, if internal resistance didn't limit them to much lower output;

5) comparisons to a washing machine motor are spurious because his motor drives no load. It just has to keep spinning, meaning that the only energy input needed is to replace frictional losses. Being larger gives his motor a flywheel effect that sustains its motion, not interferes with it.

6) the main "proof" in the video is that the ammeter gives negative values, which is no proof of anything other than a voltage spike on switching the inductor current.

Well,
the digital multimeter does not work too good in displaying the real input current.
The sampling it does just only shows some figures.
Surely there are big negative current spikes ,
which do recharge the battery and they are pretty big and don?t register with this DC type digital multimeter.
The average input current is still positive, so using up the batteries, but due to these big negative spikes, the batteries can deliver much more energy
very much longer than predicted by the battery manufacturers.
And if you use big lead acid batteries there is an additional effect  that they never really discharge at all
when run on well setuped Newman machine where the commutator produces the right spark.

The bigger the Newman coil gets ( more Kg) the better this back spike is and the more charging energy
you get for the batteries.
It also depends how much additioal energy you get from the "additional galvanic cell battery" at the commutator,
cause the dissimular graphite-copper commutator with its plasma sparking acts as a galvanic cell adding addfitional energy into the circuit.

After seeing the video of Joe Newman I am deeply impressed.
On the other hand: Joe Newman says it is so easy?
My thinking: May be it is easy, I don't know.
But when it is so easy why can't I buy such an engine in the shop round the corner of me or every shop out there?
Why aren't there machines or cars out there they run with Newmans machine?
Why can't I get a simple instruction to make my own Newman machine (I am not an engineer but it is apparently simple)?

Ok, I can hear the voices: It is forbitten, the oil concerns wouldn't allow it.
But why they allow solar energy and wind energy?

Show me a usable instruction for Newman engines and I will forget all my doubts.

I'm a Newman believer myself ..have called and talked with them also

The effect Tesla observed that was killing line men for Edison when breaking a HV DC circuit is no fantasy

I think that is what he is using  and no one has explained where the power spikes are coming from as far as I know .

Howdy Y'all,

I like Newman, he's a character, he is wise, and he is right.  In the video I think the machine is barely running just for demonstration purposes.  That gigantic motor is running on like 100mA, and it is pushing some current back into the batteries.  Amazing!  I have been researching back EMF and recycled EMF devices for some time.  I would like to get the plans for the Newman Motor.  What is sad is Newman has been pushing this thing for decades and the Power Elite have been pushing back the whole time.  Now that we are approaching the point of desperation over energy maybe people will start to listen.  The energy is all around us, all we have to do is tap into it, duh!

Blessed Be Brothers...

Hi all,

I watched the video earlier and had another go at it, it looks pretty much like the one you tested in 1998. Probably using an oval shape coil with the same rotor, torque increase is a result from possibly forming 2 vortex at each ends instead of a big one dead center. He did improved on his original design.

Brilliant man.

Take care,

Michel
