Hi Romero,

Could you please, at least tell us if the coils of a pair should be adding or cancelling (bucking)?

Regards, Garry
Of couse it is bucking, adding will work like a normal coil and mr Lenz will beat us hard.
May I ask you something, as it is considered fake why do you continue working on it?

Hi Romero,

Thanks for that.

The reason I continue to work on this is -

Early on, I asked if you were religious and I passed the comment - GOD BLESS YOU.
You responded that you were Orthodox Christian and that is more than good enough for me.

Keep well and ignore those that try to derail you.

As my mum says, the truth will eventually be know. Patience and Honesty will never fail you or anyone.

I don't think that you can trust somebody only because he is Orthodox Christian or whatever... that's just BS.
The reason I continue to work on this is because I belief that it can be done and I don't think Romero is a person who would faked it.

To me it was also not clear how to use the coil pair, the thing is that in bucking I get speedup but I can not charge the caps  :(

Edit, Maybe we can  :)

Maybe you could amplify the effect by winding 2 bi-filer coils in the same configuration.

It is considered fake because of this picture and I must say that to me it also looks like there are going 2 wires trough the hole in the table  :o maybe it is an illusion?

Thanks for the info, I tried Bifliair and it gives even better output  :)

Hi Romero,

For each pair set, which of these four parameters is more critical ( that is to have equal for the two coils of a pair)
 to aid in our final outcome -

1. Resistance
2. Inductance
3. Capacitance
4. Turns

Kindest Regards, Garry

p.s. It has only take 3 months, but I finally understand what you mean by "tuning is an mammoth task"

Hi there,
I'm playing around with a generator like Romero's, just the coils and cores are a wee bit different (soft iron cores). When i shorten the coils I can see a dramatic increase of rpm and the amperage is dropping extremely. The input is a good bit higher before I get the needed rpm's. I can see now very well what you mean by tuning the air gap, Romero. The mechanical resistance increases a lot when I get too close to the cores and the output decreases too much when I'm to far away - but funny enough: even at a gap of 12mm I get 25V out. Shorting amperage is 450 mA at that gap, not too bad ;) Will have to finish that generator before I'm able to tell the exact output/input duty, might be a quite good cop. Shorting of the coils can be done vice versa: Keep them shorted all the time and open the switch to get the spikes (like in a ignition coil of a cumbustion motor) Very high voltage, careful.....
good luck to everybody
Andi

Wow that's something... you got 12mm gap and you have 25 volt output  :o Can you give more info like the size of magnet's, the dynamo properties etc...

hi darkwanderer,
try this coil: magnet wire .8mm, 42 mm long, od 30mm (don't know the number of windings, is not critical). Core is a 8mm steel screw, 90mm long. I have turned the head somewhat down to 12mm dia and 5mm thickness in the lathe. My Rotor is probably like Romero's (Think it is 20cm in diameter where the Magnets are sitting) Poles are NS. I used 16 mags instead of 8, so the higher frequency allows to see the dropping of input at lower rpm's. My driver motor is a simple DC motor (24V), quite strong but draws only 3W when idling. Turns 3000 rpm @24V.
Funnywise that steel core did not get hot.....as long as the air gap is bigger than 5mm. I was amased to see 5W coming out of it with the big gap of 10mm, did'nt expect so much. Voltage is allways good but amperage drops a lot when you increase the gap too far. Not too difficult to get a wee bit OU here.
Regards
A

Below are a couple of links that would be very interesting to experimentors. Hope you enjoy, i found them unusual. ron

Hi Romero,

May I please have an answer to the following -

 to aid in our final outcome -

1. Resistance
2. Inductance
3. Capacitance

If this is asking too much or giving away the key, I will understand. But at least may I have a response?

Kindest Regards, Garry

Hey Romero can you please give me your opinion on the picture I posted, can you see the 2 wires going down the table cap?
