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

[txt]

@tinman: Everyone knows it is possible to harvest energy from the ambient EM field. I posted already ~15 pages ago a link to the document Ambient RF Energy-Harvesting Technologies. If you read its title, you may understand that it speaks exactly about that even if you do not bother opening it. And you can be also quite sure that I know what is in it. Your video only confirms what is stated in the document and what I am claiming in this thread since the page #12 - at this size, no useful energy can be harvested from the average ambient EM field for powering a device like the ELFE battery. That's what this thread is about. The ELFE battery is powered by 3 AA batteries and has the maximum output of 3W.

Your video showing a dim LED powered by ~500µW is useless, laughable and it only confirms what I wrote and what I claim since the beginning. You would need two years of charging for being able to power a 3W LED flashlight for three hours at full power. Lighting up a LED at ~500µW is four orders of magnitude below the needed power, and there you are lucky you are close to a radio transmitter, otherwise it would be even much worse.

PS  I just like saying that.  It sounds so ominous.

Once again-same mistake as txt-->where do you guys get 525uW charging power from ?.
How have you calculated a 525uW charging output from something never made or tested?
I stated-If the antenna was around the outside of the torch body,along with a better circuit,you could charge a 1.5 volt battery within 5 hour's i would think,and get back 1/2 an hour of usable light.
MH,can you please tell us all how you have managed to calculate the charging power of a device that has not yet been made?,or how you have determined what usable light is?.

Indeed.
If i can store a continual energy flow of 1/2 a mW for 5 hour's,then i can drive an LED with 5mW of power for 1/2 an hour from that stored energy-if we assume the system is 100% efficient. At an efficiency of say 90%(very possible),we could deliver 4.5mW for 1/2 an hour to our LED. Are you saying that we would not be able to produce usable light from this ?.

It pays to think before dismissing things that have not even yet come into existence MH.

I can estimate the charging power of something that hasn't been made because I looked at some of the information that Txt provided for the energy density that you can get from various forms of ambient electromagnetic energy in the environment.  I already had an intuitive sense for this before even looking at the data.  I also know that even a few kilometers away from an AM transmission tower the amount of energy you could pick up is negligible.   You also stated, "1/2 an hour of usable light."  Usable light is a few watts like in an LED flashlight, not five milliwatts.  That's a bait and switch.

You are the one that isn't thinking because you made the claim presumably without making any reasonable estimates or crunching any numbers.  So I am sounding out a cautionary note just like Txt.  You can think about how much power could theoretically without building it.

And the root meaning in your comments go right back to the ADGEX pitch.  They made ridiculous claims about picking up EM energy and the laughable Schumann resonance energy and the laughable claim of picking up energy from the Earth's magnetic field.  They claimed something that was physically impossible and you claimed something that was physically impossible.  The takeaway for everyone should be to understand the issues because as sure as the sun shines in X number of months somebody will be trying to sell something by making similar claims.

Post 168- Quote: The ambient EM field in standard wavelengths is much stronger - it allows harvesting up to units of μW per cm³ in densely populated urban environment.

I think your a bit out of whack with your power calculations in regards to EM radiation around densely populated area's. Lets look at the video below,and lets assume his antenna is say 20 meters long(around 60 feet),and is say .4mm copper wire.So we would have an antenna with a square area of around 8cm. Now looking at that LED,and also taking into consideration that a speaker is also being driven,we can clearly see that there is a fair bit of EM energy being collected by a very small square area of antenna wire. There is also the fact that the bulk of the population lives in an area that has many strong EM radiation sources. So now lets take the circuit used in the video,and store the energy that is being used to drive the LED and the speaker. Do you really think it will take 2 years to charge 3 AA batteries with the energy that is being used to drive the LED and speaker?-i think not.

Im not saying the ELFE is lagit-nor have i ever said that. What i am saying is,it is indeed possible to achieve the required result's ,with the available EM radiation in most cases. The video clearly show's that usable light can come directly from the EM radiation-without the need to store that energy. If we were to store that energy over a period of 24 hour's,then even more usable light over a shorter period of time could be had.

You have far under estimated the available energy per square CM of EM radiation in populated area's,where we can safely assume there is 1 or more sources of strong EM radiation.

Well you better think again--see last post of mine to txt.

You also stated, "1/2 an hour of usable light."  Usable light is a few watts like in an LED flashlight, not five milliwatts.  That's a bait and switch.

Since when did you become the one to decide what amount of light is usable?.
If i can read the words on a page in a book,then that is usable light--regardless of what you may think. If i place my little red LED (as seen in last video) that consumes only 500uW of power,next to a light switch in my home,and in the dark i can see that red LED,and that red LED shows me where the light switch is,then that is usable light,as it guided me to the light switch in a dark room.

You are the one that isn't thinking because you made the claim presumably without making any reasonable estimates or crunching any numbers.  So I am sounding out a cautionary note just like Txt.  You can think about how much power could theoretically without building it.

I base my assumptions around things already achieved by other's--unlike yourself,where you blindly follow what others say,and present in book's.-->this is becoming a habit of your MH.

And the root meaning in your comments go right back to the ADGEX pitch.  They made ridiculous claims about picking up EM energy and the laughable Schumann resonance energy and the laughable claim of picking up energy from the Earth's magnetic field.  They claimed something that was physically impossible and you claimed something that was physically impossible.

My root meaning MH,was that it is achievable,and has been done by others.
Once again,you have jumped on the band wagon without doing much research-and got it all wrong again.
