As you can see patent 284333 is already expired in czech republic (probably in year 2008). Standard period for invention protection is 10 years. If inventor does not prolong this period then patent is no longer valid.

Patent holders besides Michel Meyer are Simona Pustejovska, Jaroslav Holy and Jana Mickova, all from Novy Jicin, CZ. I havent found any contact on them but my guess is that they were only translators. This idea is supported by fact that Simona Pustejovska published in year 2000 bachelor work with title "Podoba a fungovani francouzskych regionu" which means "State and functioning of french regions". She has been studying on Charles University in Prague, Faculty of social sciences. It can be some another Simona Pustejovska however.
Patent representative was Ing. Iva Rylkova, i found email contact on her and wrote her what she remembers from Meyer invention. She was working in patent office in Ostrava. Her job was to help inventors to apply for patent (bureaucracy). But i havent found her in actual business register of Czech republic so maybe email address is old.

Do you know something more about "nuclear magnetic resonance"?

Hi Jan,
there were some attempts in former Czechoslovakia to confirm Meyer's work as far as I know. But it's so difficult to get any information - maybe you have seen this picture?

Hi All,

I'd checked their patents database and it don't find both patents,  that means they are not in force!.
Of course if You want to be absolutely sure You have to pay 6,5 euro for official paper about patent status.

Hello all - a very interesting topic !

Just my 2 penneth worth...

Last summer (2009), I was performing some modifications to my latest plasma speaker system.

The system runs at approx 100Khz, 30V Sq. AC with a low duty cycle / M-S ratio of <10%

In testing, I noticed the cable connecting the controller PCB output to the transformer was becoming exceptionally hot, to the degree that the insulation was starting to become soft and melt.

The input power, 30V DC @ 2A (60W) to the controller, was consistent with previous 'runs', the ONLY difference being the length of the cable used on this particular occasion.....

The unit performed exactly as in previous tests, with the same power consumption & same plasma output. NO RF was picked up around the cable, which I guess rules-out inductive heating.

It was only when I stumbled across Michel Meyer's work, that I noticed a correlation.

For what it's worth, the cable length used was 55.5cm, composed of twin, 80 x 0.18 CU wire.

When changing the interconnect to a different length, the cable runs stone-cold, with exactly the same power consumption and plasma output as before.

Please note, there is no tuned circuit involved, so this cannot be a factor in the heating.

Some of my videos of the project are here, including a TV job :

It would be interesting to hear any thoughts on this very strange phenomenon.

Cheers from England, Richard

hi timetec.

i just wanted to say when i first saw your plasma speaker a year and a half ago, your beautiful build inspired me to build one of my own. thanks.

i have not noticed the phenom you mentioned, i might have to dig it out and play with some wire lengths... i am using a single 555 circuit, single fet.

thompson twins... great choice!

Hi - thanks, good to hear you had a go at constructing one yourself

I can only concluded that something is happening within the copper cable itself...

No extra power input / no extra power output, but excessive heating of the cable between the source and load.

I tried using a primary only at the time (with no HV winding) - just the same heating effect - very odd.
The problem is actually metering the cable - a standard AC clamp-meter will not to give a reliable current reading at >100Khz AC especially with such a short M-S ratio.
