I recommend that you do the research on batteries and how they work. The chemical energy in a dead battery is still there, and can seep out slowly over a very long period of time. This is a perfect match for the LED, because it is very hard for the LED to bring the batter down to less than 0.6 volts. Therefore the battery and the LED slowly do a dance of death towards 0.6 volts and beyond, and the weaker the battery gets, the less the LED demands from it, because of the way LEDs work.

i have made a tube with a telsa coil and a battery that runs a motor and the batter charges it self back up and then powers the motor again this device has been running on 9v battery for about 8 months now and i think im making a breakthru w/ a good way to run a HOUSE a Car a "death ray" etc. laser etc.

Can you make a video of it and share with us? Could you send me the schematics?

Mr Plengo im interested in replicating this as im new to electronics and and find these little experiments fun but i do not have a stop near me to buy the parts so i tend to recycle what ever i can well i have found tonnes of these mosfets(stp55ne06)and was wondering if they might workin this circut also i have these pnp transistors(2N3906)just wana know if they might work
thanks,

i also found this mosfet irfz24n

the 2n3906 should work. THe mosfet is very important because you will have to play with it until you get it running right. On my video 4 (I think) I show that. Go ahead try it. But I must tell you it will run for a long time if you got it right otherwise it will just run the battery down. My is still running as of now and its passing the 7+ days now.

How long did it last?

I built a simple diode driver using a lm317 regulator powered by a 9v alkaline battery to light two high-intensity leds as part of an art installation. After taking down the installation, I decided to leave the circuit running to see how long it would last. A month later, and the diodes are still lit!! A little glimmer of light on the longest night of the year... Warms the heart indeed.

The coils, coils, and coils. The secret appears to be in the bi-filer coil design. This is really amazing accomplishments. Congrats!
Was playing around with one coil made myself. Pulsing it with LONG pulses, but still you could see 200Volt spikes on the oscilloscope. The input was only 12Volt on the other winding. The secret is increasing those spikes of overunity in the coil itself.
