World's first real Free Energy Flashlight - no shaking - no batteries! No Solar

[txt]

But I have the impression that the damned flash light will shine three houres a day for many months (disregarding brightness, which is hard to discuss legaly).

The Russian guy measured the current of ~35mA in the second video, and 1.3V per cell in the first one. It gives the power consumption of ~0.14W. Assuming the AA cells have the capacity of 2600mAh, there is storage of ~10Wh. That would allow for 72 hours of operation at this intensity. And as the voltage and luminosity drop, the total life may be longer (perhaps in the range of ~100 hours - that's roughly 30 days with 3hrs/day). Of course the luminosity will be much less than 100 lm, but there are not too many users who could measure it reliably.

The voltage of some types of batteries drops under the load (hence the decrease of luminosity), but when turned off, the electrolyte chemically recovers, and the voltage raises during the rest - that explains that the flashlight starts lighting stronger after a few hours of rest. It can indeed take quite some time before you completely drain the batteries.

It's good to hear that someone at least received something.
I hope i will also receive my ELFE soon. I'm also in Germany.

@txt:
If it really has 120 lumen it would not be possible to operate it with only 0.14W.
Good LEDs have 100 lm/W (the best LED available has 300 lm/W) so with 0.14W it would only give about 14 lm.

Also the calculation with 8 µW can not be correct. 8 µW would give only 0.19 mWh per day.
With 0.14 W this would only allow for 4.8 sec operating time per day.
To operate with 0.14W for 3 hrs/day you would need (0.14W*3h)/21 = 20 mW to recharge it during the remaining 21 hrs.
If the LED needs 1W you would need 140 mW to recharge it in 21 hrs.

Yesterday it was switched on for 4 hours. After the first 2 hours the light slightly darkened , after the complete 4 hours you could only see the middle of the spot. At this morning , when switched on , the light has regained intensity with no doubt.
But I will test it , if this is true on the long run.
Next it will be drained completely and it will be tested , if it will be able to recover to whatever extend.
I have this thing lying on the table and will nail down facts that I observe, and eventually depending on results write some harsh comments, that Mr M. will have to focus on other 'business models' in future.

I'll be interested to hear the results of the long term discharge/recharge test.
According to the Adgex website, if you discharge the ELFE flashlight right down
low by leaving it turned on steady for 12 hours or more, it can take one to two weeks
to fully recharge again. If the ELFE can really fully recharge itself again as claimed
after about two weeks, that would be really something. Ordinary batteries may recover
a little bit, but they certainly won't fully recharge after two weeks after being run right down.
I realize this seems unlikely, but I think it wouldn't hurt to test this just so you can say to Adgex
if it doesn't recharge that you actually tested it by leaving it for two weeks to recharge.

If it does recharge as claimed, then maybe those are not ordinary batteries.
Adgex does have a video released about a year ago about some special 'porous nickel' ('nickel foam')
NiCad battery technology which they say they are developing. As slim of a chance as it may be,
I think it would be interesting to put the ELFE through a full two week recharge test after
duscharging it right down low to see what happens. If it doesn't recharge fully, then at least you
have actually put it to a real fair test.

The Russian guy measured the current of ~35mA in the second video, and 1.3V per cell in the first one.

Edit:
Hi txt. In the first video he showed what appears to be a different current measurement.
In the second video, could he be measuring the current after the batteries have been
run down quite a bit? I have attached a screenshot of the current measurement from the first video,
although I am not so sure at all that we can trust his measurements using that meter.

I am not sure what 2600 and 2500 and the numbers mean It has 3 2500, 2 2600 and 1 2500 on the side of the 3 cylinders inside the torch. I could make a guess and say they are batteries and this refers to the battery number and the second number is mAh but thatwould be a guess.   The fact they have different numbers is interesting as why would you number the batteries, who cares what order since it is in series and why different amperage?

As the Russians Crude circuit diagram shows and MH hinted at this is an open circuit so nothing external could be charging them unless an external induction charger was in the torch but I don't see one.  It is pretty well shielded as well with a double tube construction so I don't see how the 3 numbered cylinders could  scavenge for power either. 

So that leaves us with the assumption these are nothing more than 3 rechargeable batteries that sit for a week and can then just barely manage to  pump out enough voltage to light an LED for a couple of hours. We will see :-)

Have we hack sawed those batteries in half yet ...
