That is interesting, i will have to experiment with the location of the sphere connector.

I have some interesting results, can anyone confirm these 2 things for me??

1) the current appears fo be proportional to the size of the sphere

2) voltage appears to be proportional to the number of turns in the primary divided by the number of turns on the secondary windings. - i.e. - increase the total number of turns on both coils and thus should increase the voltage.

im running out of ferrite rods, my longest one thus far is 14 inches. If anyone could play with a larger set-up that would be helpful.

hyp.::    if my calculations hold true, a 1kw unit should be approx 2-ft diameter hollow sphere (copper or aluminum)
and approx 300 turns on the primary / 150 on the secondary. 

currently my biggest problem is an inconsstency in the curent when a load is attached,  the current drops exponentially from 130ma down to 0 after a 10-15 seconds (with a 14-inch rod [60/30 turns] + 9-inch sphere)

This leads me to believe the sphere is acting as a sort of "capacitor", charging over time from the induced voltage diference. I need to experiment with completely discharging the sphere, then measure the "charge time" along a current-based-scale. 
Im guessing there is relationship to the charging-time of the sphere, to its discharge time  (i.e. -current out) . 

Solution:::--  Construct two devices, discharge one intentionally, at the halfway mark of the discharge time, to offset them, then collect them as a low-voltage A/C signal, through a square-wave rectifier to produce a (steady) DC output.

any thoughts? or anyone that can test these things and confirm/deny what im seeing here? thanks.

have read on the subject,and seen drawings,you can look up peter markovich,and see the drawings at rex research.com very interesting information,hope this helps. thanks jrader

Hi sm0ky2,
what about voltage???

[sm0ky2]

my 2 largest voltages thus far have come from the 9-inch spheres (these are the argest i have)

copper sphere (9in) yields a consistent 0.13v DC potential between the lead from the secondary lead ot the bottom of the rod.  (-0.13v if measured in the other direction)

the aluminum sphere (9in) yields a varying voltage potential between 0.04 - 0.9v DC, im not sure what causes the variance - my two best guesses are temperature and/or the mixture of different metals in the aluminum alloy.
[i could not obtain a hollow sphere made of pure aluminum - they are hard to come by, and i was also told that it would quickly form an oxide layer on the outer (and inner) surface, which would act like an insulator, destroying the effect we are trying to achieve.]

My next attempt is going to be constructed with a hollow Brass sphere, im shooting for 12-14 inch if i can find one.
if it has to be custom made, i'll get the biggest one my pockest can afford.

at best, what i have is approx 2/100th's of a Watt, which decreases over the discharge time of the sphere (capacitor).

i have not yet been able to achieve a non-stop DC output of any measurable current, the current is only present when i let it "charge" for a few seconds.

also i have found an increase in ferformance when you completely seal(air tight) the hole in the bottom of the sphere, around the rod shaft. - this seal also doubles as an insulator for the inner coil lead, between it and the sphere, allowing a much closer solder point at the top of the rod. - although my next one will be attached actually up INSIDE the sphere just under the "point", my mind keeps telling me to do this for some reason, so im gonna go with it..

Brass should perform slightly better than the copper, it lies between copper and silver on the list of metals
silver, gold, or even platinum/titanium are probably the best metals to build this device out of, but i am not rich enough to build a golden toy

honestly i think the "ground-battery" gives a much better power output for the cost of parts, but this does have the advantage of mobility, so im going to toy with it for a little while longer. - if anyone has suggestions to try, or results of their own i would appreciate as much input as i can get at this point.

p.s. i mentioned in an earlier post about using a ferrite rod - disregard this - continue using non-ferromagnetic rods, it does not have the advantage that i thought it would have, and may in fact decrease performance, or at least make it inconsistent.
