Kapanadze Cousin - DALLY FREE ENERGY

  Yes, each bulb lights in a different way, depending not just on the wattage, but the brand, as the voltage is the same, all are 110v.
  So, the load becomes part of the circuit, and some lower wattage bulbs, like a 40 watt bulb will light much less that a 50 watt bulb. Possibly a 60 or 75 watt bulb may light better yet. Although I can dimly light a 100watt bulb on 12v, 500mA, but not off of the battery.

  My pc fans are not burnt, but may need a start capacitor that may be included as part of the pc motherboard that they were original mounted on. Although one would think that kick starting the fan by spinning it be hand at first would start it, like a start cap would do, but it doesn't.

The caps I suggested should filter out some of the HF hash preventing the fan to work. The fan does not need a 'start' capacitor, as in motor start capacitor. They work directly from a 12V DC PC supply rail.

The Royer is very load sensitive as you have found. Its all about matching impedances to get best power transfer.

The PJK ebook had some ideas in it how to divert the reflected flux away from the primary.

Maybe irrelevant to this thread, but i think the efforts to manipulate the flux in a genre of suggested OU devices is wrong in my understanding. As i see it, flux is energy. You cannot have 2 windings one creating flux and the other harvesting it and the same time not affecting the primary. As i understand it, a secondary of a transformer does not create a counter flux (even it appears that way) rather than "consumes" it resulting in a net diminishing B-flux in the system.

In the same grounds, as i see it, (i stress the personal view) permanent magnets have the potential to indefinitely create flux (like batteries), but so far the magnetic semiconductor is not available.

PC fans don't need a "start capacitor". Every 12 volt pc fan I have will run just fine on a 12 volt battery, or a power supply. Most will run with less voltage, too, so you can "dial" the speed of the fan that you need.

100 Watt light bulb filaments have less DC resistance than 50 watt bulb filaments.

So one more reason could be to care about the impendence of the bulbs themselves, and try with DC strait filament bulbs too...

Yes, but all the matching in the world is not going to light up a TK style lamp array from a small Royer oscillator alone. As Nick has commented, he is not really interested in lamp brightness, just the missing link for loop-back self-running.
