new magnetic motor goes 2000 rpm without load 1000 rpm with load

[hakware]

I have been quiet watching this thread.

I call bullshit. This is another lost hope and dream. Lets see some real data.
Schematics anyone? oh wait, theres a hamster in that wheel! Ahh, that explains it.

The best part of that video was the guys T shirt which reads
"fat people are hard to kidnap!" and I would be willing to bet the only truth
to the whole video.

Move along people, nothing to see here.

Well,
I guess this video was probably not shot to show
the device to a worldwide publicum,
probably just as a personal documentary or to show the
main function to a few friends.

This is probably also,
why they pulled it off from Youtube.


I agree with EMdevices,
that you can pull out some more energy
out of a battery, when you match the impedance,
BUT they have shown to pull out about 500 Watts
constantly for several minutes in this video.
This would mean at 12 Volts pulling out about 42 Amperes
constantly...

Before it was not possible to pull out at all maybe a few amps
to start the inverter.. so the battery was really dead.

So I don?t know, either it was faked somehow, so that he
hiddenly connected another 12 Volts power source
or the device is for real and really delivers so much energy.

Just via impedance matching alone it can not be explained
to pull so much power from the dead battery for several minutes.

Stefan, did they measure the 42 Amperes in the video?Ã, Ã,  I don't remember seeing it, but I'll tell you, if a battery is starting to go dead the inverters will not work, they realy depend on that current.Ã, Ã,  What I do remember seeing is the drill and jigsaw running idle.Ã,  (not loaded down)Ã,  This does not consume much power at all, its when they are loaded that they realy start drawing that current.Ã,  And if you noticed, when he started to drill the wood, it woldn't work to well and he kept saying stuff to excuse the situtation.Ã,  He has quite a bit of inertia built up in the motor and as he was drilling in short spurts,Ã,  the motor seemed to stall, then he would pause for a second to let it build back up in speed and tried drilling again.Ã, 

Here's another way to think about this situation.Ã, Ã, 

A large battery internal impedance will only rub us of power if current flows.Ã, Ã,  It's those I^R losses.Ã,  Ã,  Now, even when we are matched,Ã, Ã,  we still waste half the power.Ã,  Ã,  Now,Ã,  we can be more efficient in extracting that power from the battery, with a very high impedance load so only a little bit of current flows and our I^2 R losses are as small as possible.Ã, Ã,  But the average power goes down.  However,Ã,  if we need pulsed power, we can get a lot of it.Ã,  Ã,  Imagine you let the charge leak slowly out of the battery into a capacitor, then short the capacitor.Ã,  That would be a burst of power.Ã,  Ã,  In this case,Ã,  the power leaks slowly into INERTIA of the motor, then he uses that power to drill in short bursts so he won't stall the motor.Ã,  Ã,  But as far as running a motor without being loaded down, that doesn't draw much current.Ã,  So seeing a jigsaw and a drill just spinning is not an indication of power.Ã, Ã,  I bet those two things alone draw less then one watt in idle mode.

Having said all that, there is still some merit to this kind of setup, and that is to extract the very last drop of energy from a battery.

EM,
just take your hand drill and jigsaw and
measure the input current while you drill or saw.

Probably not lower than 5 Amps at 110 Volts...

[EMdevices]

Stefan, I agree,Ã,  when in operation (or loaded down) those devices can draw quite a bit of current, hence power.

So, do we know what speed his flywheel was running at?Ã, 

If we can get that figure, we can approximate the energy in the flywheel, and see how much power he can put out in short bursts.
