Richard VIALLE's new theory about negative mass and overunity

[Khwartz]

Further tuning.

- The 145pF capacitance in parallel with the coil is still good.
- I've tried adding small amounts of inductance & or capacitance in series or parallel with the bulb, and have only seen the bulb dim.
- I've tried connecting the GND to one or other of the bars - and that gives a small increase in brightness - when connected to either bar.

What's going on...?

Capacitive vs. magnetic coupling...

There are 2 reasons why it looks like the effect is due to capacitive coupling:
1) The addition of the ferrite cores makes no difference
2) Placing my hand on the coil makes the bulb go out. If it was magnetic - I don't see how this could happen.

Relative Power Usage

- The test bulb with 12v DC uses 0.4a, and makes about 40,000 Lux (as tested with a luxmeter at zero distance)
- If powered by the circuit - the bulb needs about 45v and 0.3a to reach the same brightness. (Ignoring the gate rdriver)

Questions

- If it is capacitive coupling, I don't understand why it has particular resonance points. I suppose caps do have their own resonances...
- I don't really get why the 2 bars inside the coil would be oppositely polarised.

Next Steps

- I have a ZVS driver with a bad mosfet that I need to fix. Maybe tomorrow.
- I want to try running the coil with the ZVS driver - it's likely much more efficient.
- In order to do that - I also have to add another layer of winding to the coil - so there will be two. I know that's not typical for the device, but hey...
- I might actually just do a new coil, with fat wire - as the ZVS driver prefers lower inductances, and fewer turns.

Did you try to connect one extremity of one half bar to the same side extremity of the coil? Biganos did it with success and an other experimenter of Cos too. If I remember well they connected it to the "0" point of the signal; something like that. (Which looks to me avoid at least partially the possibility of capacitive coupling while both coil and bar are connected...).

Hi Khwartz,
  thanks

I'm considering buying one of these SWR meters - 1.8 - 525MHz:
http://www.pjbox.co.uk/maas-rs-600-swr-pwr-meter.html

I'm considering getting into CB radio - to make the purchase worthwhile... lol. Actually - I'm planning on doing a load of experiments with HF eventually too - such as John Kansias's burning salt-water, Hutchinson effect etc... So i'm sure it'll be useful.

I'd like a VNA - but I'm not sure I can justify the expense of buying one... I'm still mulling the idea of making one, but I can't even get my ZVS driver going...

That's logical reasoning

Wouldn't be you both forget it is supposed to be about mainly inner coupling with the energy of electrons? And that it is supposed too to be about a magnetic flux sent back in the coil by the cold current in the bars (for negative power)? That inner core doesn't matter much because current locates maily close to the outsurface the the bars? none of  what you notice looks to me to avoid these supposed and expected phenomena; or I am mistaking?

[Khwartz]

That's a good test of the output power if the luxmeter does not get saturated and the inductive reactance of the bulb is low.  Putting the bulb and the sensor in a dark box would be prudent (see Grumage's Wattbox).

Good one! Again

However the bulb is not a good indicator of the input power at all, because a bulb in series with the input measures current, not power and the MPTT rears its ugly head.

Wasn't it only for comparison test on DC power, to have an "unit" for output power estimate then, when the bulb placed at the output ofthe bar?

[Khwartz]

Unfortunately I have replaced the mosfets, but the driver's still not working... It'll take another leap of understanding for me to fix it.

Just to let you know that Blue, in his last vid, uses Arduino stuff and Biganos amplifier.
