Joe Newman has a new car !

[mbell]

I have followed Newmans story for some years now. I think he has proven he has something that works. The truck however is very slow. I can see the advertisement now "zero to town in 2.5 days without a charge" (LOL) I think the technology would be better used to power your house.

I have worked a very long time on the Newman
things.

The basic effect is:
it is a DC motor basically with the rotor just having
one or more permanent magnets.
The stator are coils switched via a mechanical commutator.
from a battery power supply.
Many batteries in series to get a high input voltage
and using small diameter wire to use only milliamps
of input current, so the batteries also last longer.

The main effect is then the mechanical switching of the
coils via the mechanical commutator.
It only works via mechanical switching.
There is the back EMF energy abruptly jumping via the commutator
and together with the 2 different material for the commutator this
is converted into RF bursts, that recharge the batteries.
As there is also an interaction of the coils and the magnets
the spark at the commutator is getting bigger and thus
there is more energy being produced and the batteries
are charged back via an superimposed DC pulse inside
the RF burst and sparking.

It is pretty complicated.
But Newman just did, what you normaly don?t do.
He worked out how to make the spark bigger
at the commutator by using multiple commutator in series
and thus have a faster dI/dt current switch off and thus have more induction
voltage and a bigger spark.

The fact is, that he can produce a lot of RF power with this
concept and the batteries seem to stay charged due to the
RF bursts they permanently get from the switching of the mechanical
commutator !

With electronic switching it DOES NOT WORK.
So don?t try it with transistor switching, it just does
not work. Have been all through the years with it.

There must be sparks jumping to have the effects.
And you have to have the right commutator materials,
like copper and graphite.

have a look at my work at:
www.overunity.com/newman
and
www.overunity.com/newman2

The problem still is, that also with big machines,
you have pretty low mechanical output as you can
see, that his car is running only at slow speed.

In this motor he probably produces more RF power
than mechanical power, so he mainly keeps
the batteries charged and does not have such
a big mechanical output.
Also he has
many losses in this car motor to bring the
power to the wheels as it is build.

Also he has pretty big airgaps between coils
and magnets, so the motor
is not so much efficient mechanically,
but the batteries just stay charged due to
all the RF he generates and the superimposed
DC back current spikes.

Also you need lots of copper wire for it
which is expensive.

If you have specific questions, just ask.

thank Stefan, its sound complicated to replicate

Well,
it is not so complicated.
Just build a very big coil with say 1 mm diameter copper wire,
well isolated
and use at least 20 Kg copper wire for it.
Then see, what kind of ohmical resistance you have of this coil
and use at maximum the voltage, that gives you at pure DC voltage input maximal
100 mA current, so if the coil has a DC resistance of 1 KOhm,
use maximum 100 Volts as the battery power supply and use
10 or 11 x 9 Volts accus in series.

Then take a big noedym permanent magnet, which
you let rotate inside the coil and fix to it the commutator,
so it switches every 180 degrees the current inside the coil.
This then works as a 2 pole DC motor.
Make sute you use graphite brushes and copper rings
as the commutator and make sure you don?t suppress the
spark, when the commutator switches and reverses the current.
At this moment you have a big back current spike back to the battery and
this will recharge your bytteries.

Just try it.

Newman has now a faster running car !

Watch this:

http://video.google.com/videoplay?docid=-9094515037555440762&hl=en

This can now be scaled up to run at 70miles/hour with not discharging his
batteries.

This will be very nice !
