@scratchrobot . You are not the only one thinking about Romero`s switching method .Why not drop him a line care of Want Dynamo Bay ? And while you are at it ask about Penno . I dont have lot of luck with reed switches . Does anyone know if they are available in different sizes and current ratings ?

I dont have lot of luck with reed switches . Does anyone know if they are available in different sizes and current ratings ?

I started with small reed switches and they worked just brilliant - until burned. Reaching same performance on small system is impossible with solid state stuff. Record was that I had motor drive running on 0.1V and output was 500V directly from the gen windings. It tried to move to larger reeds but they are slower and do not work so good - and in the end burn also.

So finding something that does work as good as reed but does not burn would really breathe new life into this shorting business.

On thing he did was wind a coil directly on the reed, but it would not solve the problems entirely.

I remember strange comment from rom about output voltage of gen windings. If he was using some clever/hidden shorting method then really - output voltage would be not tied so directly to inductance or resistance of windings. But of course that's just a speculation.

Maybe this has something to do with shortening coils at the right current moment instead of choosing the 'right' voltage moment.
I noticed most of you indicate to use the voltage curve and indicating the right moment of shortening is at peak voltage.

But, please remember that current and voltage are mostly out of phase, depending on the load, between 0 and 90 degrees, so not necessarily always 90 degrees.
Shortening of coils at the moment where current is crossing zero value is interesting to look into.
This means not always the peak of the voltage is the best moment, but probably in most cases somewhat earlier in time.

Remember: a coil holds energy equal to 0.5*L*I^2.
At my proposed switch moment when I^2 is zero (energy in the coils is momentary zero!), but there is still voltage over the coil.
But there will be less of a voltage spike over the (mechanical) switch when switching at I = 0 rather than I is not zero. The extra voltage spike that will be introduced when I is not zero is U=LdI/dt,  and since dI/dt is very large due to sudden current swich off, voltage peak will be much larger than the voltage over the coil at I = 0. The extra voltage spike causes wear and tear of e.g. reed switches.

Hi everyone,

Concerning shorting of generator coils

I have found some years back that when you add a magnet between the contacts (switch) of a coil it seems to give it a Bigger Kick

Could it be possible that Romero was testing shorting of generator coils with reed switches but by accident one of his coils was shorting itself (at the ideal location with a magnetic spark gap) because of inferior or cracked wire varnish which could of made that coil work much better and much longer than the other coils using a reed switch.

Could it be this that Richard Willis (Magnacoaster) has also accidentally found

To all, please explore and experiment with this possibility

Please also share your findings as I am freely sharing.

teslaalset Sorry mate, but I see this situation in a different light. Maybe because I see electric current a 'bit' more like this:
Electric current:
If we have a wire and we apply a voltage potential to its ends, at this moment conventionally understood current doesn't flow yet but the wire somehow emits a magnetic spike. The higher the voltage potential difference the stronger this effect gets. Tesla noticed this when in a power house an operator was closing the main switch to connect a big dynamo to a transmission line. At the exact moment of the switch closure  there always was a 'shock wave' coming out of the transmission line that could be sensed on the skin of people standing nearby. This Radiant Energy is responsible for magnetic field around a wire, not the flow of free electrons. So what could be happening inside the wire is this: The electric potential difference polarizes free electrons and valence electrons as well the same way a magnetic potential polarizes magnetic domains in a core. Spintronics says that an electron has N-S field an that it can rotate to align those magnetic spins to an outside flux field. So my thinking is that those valence electrons of copper atoms ar responsible for the strenght of magnetic field around a wire. The field created then acts on the free floating electrons making them move in direction of this magnetic vector.

So at the moment when on a generator coil we have the maximum potential difference, it is the best moment to do the shorting. The polarization vector is the strongest and it will cause the most of the free electrons to flow although with a delay...

This is how I visualize this situation in my mind. What do you guyz think about it?
