I had not realised that this is a claimed alternative energy magic power source concept. It is never worth my investigating those as the magic goes away and hides as soon as I come near and refuses to come out to play until after I leave. If this is able to be replicated it is able to be measured and the people doing it should provide measurement results. If the system uses magic which cannot be measured they should say so and we can get on with other things.
Somebody else mentioned 12 hours but you'd want a signed affidavit on that one. You can get a good appearance on an LED with 1 mA and a bright flash at an average of say 0. At 1 mA and say 2. Inductor energy my explain what is happening but you'd need relatively immense currents and substantial inductance - more of both than seem likely to be present here. So - hat I wrote before I'll leave BUT in fact I think either magic is happening my job here is done or things are misunderstood, or a series of pulses convey a sense of brightness at actual low power or its a hoax.
The experimenter SEEMS genuine enough - but this would be very easy to 'cook' and I have seen any number of fraudulent claims. There is no magic here, alas. I see nothing that surprises me energy wise.
A good modern LED will provide useful output at 1 mA so your energy calculations are in the right order of magnitude for what you are seeing. Farida Yesmin. Khalied Hafeez. Ebby Onyekwe.

A look at related circuits and associated videos show that the actual circuit in a given case may not be exactly what is drawn and also that they are using parasitic coupling of various sorts in some cases.
V2 - hard connection to base shown for feedback circuit. V3 - high value resistor provided for feedback. These sites and videos are kept going by a mix of credulous somewhat-technical tinkerers who can't quite replicate over-unity but will get there soon, and outright fraudsters who fake things to get attention. The tinkerer often gets drawn into circuits involving some resonance, at frequencies a bit beyond the capability of his test equipment. Or circuits with mechanical interruptors that lead to very small duty cycles.
These can lead to tantalising hints of the "vacuum energy" or whatever, when in fact his multimeter is just overreading the kHz voltage, or not capturing the short high-current spikes. He enters a positive feedback loop of course; he'll slowly optimise until he's found something which exploits his test equipment's faults.
Tinkerer circuits often involve a lead-acid battery, possibly because its low internal resistance means bigger, harder to measure current spikes. The fraudster creates outright fake videos, not difficult to hide the wires when you control the camera.
