And do they switch off as soon as that pole recedes from the switch? Assuming the motor works on attraction , how is the coil switched off at top dead centre so to speak .

hi neptune

might be helpful initially to think of them as a solid-state reed switch

position them relative to the mag 'fly-by' in the same way**, such that they switch on/off at the required time

all the rest is electronics - they have circuits for that

i'm told

Now Laurent,if you could wind just a second
equal coil and make these tests just on this COIL PAIR as Romero did,
this would really help to see the basic effects.

With 2 coils in series your output voltage should reach about 20 volts peak, so this would be a great test to nail down the effects.
Many thanks in advance.

yeah, and Elvis may not be dead


i think we dealt with Romero's 'fake/forged cap' several times

when the generator gets disconnected from the cap/converter/motor system this so-called 'fake cap' is unable to prevent the rotor from running down to a stop in 100 seconds

please don't clog the thread with this again, unless you have evidence or something new to say, thanks


i didn't have to 'calculate' the run time - i observed it in the video

when the generator IS connected to the cap/converter/motor system, and the BATTERY gets disconnected, then the device runs until switched off (ie. for at least 10 minutes at 12V, plus some minutes at other volts)

at battery disconnect there are 5.3 Watt-seconds of energy in the cap

the motor needs 7200 Watt-seconds of energy to run for 10 minutes (600s)

we know from my point above that the cap on its own is incapable of keeping the rotor running any longer than 100s - and all that time the rotor is running down, not maintaining speed

you have not explained where the excess 7194.7 Watt-seconds comes from, to keep the motor running, overcome the DC converter losses and occasionally light a filament bulb

please do not say "from the generator side" , because the generator will only transmit energy if the motor is performing work

what gives the motor at least 7200 Watt-seconds of energy to keep running for more than 600 seconds?

we've already seen that it is NOT the 5.3 Watt-seconds of energy in the 'fake/forged' cap

and it is NOT the 100 seconds worth of 'inertial' energy in the spinning rotor



i'm pleased to see that you keep all your equipment well lubricated

@nul-points,

I know you’ve dealt the capacitor and stored energy issue several times but imho you are wrong because you want so much to believe the setup is real.

My main question is why the DC2DC converter is still powered for >40 long seconds (first OU movie), from switch off time (18m49s) to rotor spin down (19m30s)?!!!

Here is a relevant quote on that, quote taken from one of your former posts:

“snip
at 12V i/p the motor draws 12W

so - at switch-off, with 5.3 Watt-seconds in the cap, and even IF the DC converter could convert it all (which it can't!) then the cap can only supply enough energy to drive the motor for less than HALF a second!”

Excellent post but later on you’ve (unfortunately and mistakenly imho) slightly changed your mind so the main issue is not longer addressed.
Again: if there is not enough energy in the cap to run the motor but for half a second AND the output of the DC converter is still connected to the drive coils AND the motor is on (because nothing else has been disconnected except the generator coils from the input of the DC converter) WHY, WHY is the LED of the DC converter on (and quite bright) for >40 long seconds, like I said before?!!!

Please consider that DC2DC converter is ON LOAD AT ALL TIMES, load is taking about 1A at 12VDC, and time constant for 47mF/15V on that load is hundreds of ms at best so the capacitor shall get discharged and the LED shall exponentially dim in maximum 1-2s…

So, “Houston, we have a problem”.
Apart from the above, you try further on explaining the behavior in terms of OU but it seems to me that the only possible explanation is that, unfortunately, 2 wires leading to a 15V external power supply are hidden in the setup. The switch turns the external power on and off. And the generator coils are (most probably) connected at all times with the 47mF/15V (otherwise the LED would go dark in no time after switch-off). Anything else would not explain all the facts imho.
It wouldn’t be too hard to conceal two wires in both setups (fixed and hung-up). In the second case, the external power source is not 15V but significantly lower, maybe 4-6V. I’m saying that because, to be fair for all the parties involved, one possible explanation for the “LED anomaly” that I’ve got on PM is that the DC2DC converter might have an internal protection that shuts it down in case input voltage falls bellow a certain threshold. I can not agree with that mainly because of the suspended setup. It is clear that generator coils can not possibly generate much voltage at such low RPM and yet the DC2DC converter in on and happy. So, the only possible explanation I’ve got is contradicted by the second movie…

Please refute me but based on facts. I would love too this device be real.

Hi Tinu,
you have a valid point here,
But you and we don´t know, how the DC2DC converter behaves.

At the end it was set to 9 Volts output voltage I guess.

So what happens then, when the DC2DC converter gets less input voltage
than 9 Volts ?

I guess it will shut off and will not use any current anymore and the LED might
be still on for a few more seconds due to an internal cap maybe ?

So maybe the rotor is then freewheeling to just run down its inertial
energy and runs this down until the friction has eaten up all RPMs ?

I think, somebody who has the exact type DC2DC converter should
do a test to see, how this converter will behave if the input voltage
is lower than the set output voltage.

Many thanks.

Regards, STefan.

@Laurent (woopy)

What I see from your and Lidmotor's tests: The coils need a lot more windings to produce a decent Voltage.

Only Fausto (Plengo) could get about 12 Volt with his relays coil which has very many windings, 156 ohm and 155 mH.

See his video http://www.youtube.com/watch?v=3pHLKPciCGM

Fausto's video agrees very much with your finding that a stator magnet in repellent mode reduces cogging and does not hurt Voltage.
