MEG-GA Joule Thief with very long runtime on just 1000 uF cap

Wow, how long this simple setup runs on a 1000 uF cap with this bright light:

if you charge up a 1000 uF cap to 6 Volts it has just got only 18 MilliWattsseconds
of energy and the 9 LEDs are as bright as probably using 10 mA DC current,
so with about 2.5 Volts Threshold Voltage these 9 LEDs should use about 225 MilliWatts...

So the LEDs should go out already in less than 1 second, but here on the video it runs still
7 minutes and the inventor claims longest run time was almost an hour...

WOW !

It is a nice build.  LED brightness especially on camera can be very deceptive.  When he gets around to measurements we will be able to tell how efficient the circuit is.

Guy's-please wait for the next video before rushing in. This device was ment to show how easly people believe what they see,and i had to make it as real as possible. My intention was to show every one how all these so called OU devices can be simulated with very few part's.I have emailed and spoken to a few people about what i was doing before the video was even made.This one was to simulate what the Akula device apparently showed-and nothing more. I did reply to Stefan's message,and clearly stated that the device was NOT OU. Suprisingly enough,Stefan was the only one to question and calculate what the cap could actually output,and it was no where near enough to do what the device showed it was doing.

The device dose opperate as shown,and has a very neat square wave. But it is opperating on about 2.4 volt's and below.

A timely post TinMan, avoiding yet another long thread getting nowhere towards self-running. This may be an opportune time for a fun new thread to practically show different methods of faking using a minimum of components. The entry judged to be the most innovative, receives the Akula challenge trophy.
