Joule Thief replications - not overunity

[guruji]

I think JT if it is tuned rightly regarding turns to the transistor base can produce very high voltage and charges quite fast producing a white glow to neons. Maybe when produces very high voltage it would be near OU.

Hello. I think I might have something worth looking at.

Please take a look at this circuit and let me know what you think. I have built this and have had some "interesting" results.

All the components are generic, but the largest supercap I have now is 6 Farads. (I know values many times that exist.)

Try starting the circuit by temporarily charging the supercap.

(I don't believe a Joule Thief style circuit is capable of overunity, but I think there is a possibility of the supercap "translating" surrounding
energy (ZPE?) into usable energy. This wouldn't violate any of the laws of physics, but it could possibly give us access to energy we previously have not used.)

I have read the topics on this website for quite some time now and am very impressed with what I have seen. This is my first post.

Just wanted to say I added a 1N4001 diode in series with the LED that seems to
help the circuit "stay alive longer" (another 1N60A might work better there because of the lower junction voltage, but alas, I don't have one....) I have also tried increasing the value of C1 to 10uF, which produces brighter flashes, but my overall goal is to extend the operating time using the ultracap rather than a battery.

I would sure like to see what could be done with a lot larger ultracap...

Once I did a circuit with a 650F cap that gadgetmall posted but I'm afraid using it cause don't want to charge it above it's voltage .
Is there a safe and simple circuit that if it goes beyond it's voltage can drain the charge or light a bulb for safety?
Thanks.

Just buy a zener diode on the needed value and try this:
