Using cardboard, tape and a pencil to produce energy

- Опубликовано: 24 янв 2016
- The principle underpinning this system is well known: static electricity. All you need to generate a little electricity is cardboard, teflon tape and a pencil. A team from EPFL, working with researchers from the University of Tokyo, has taken these materials and come up with an 8 cm2 device able to generate electricity. In other words, a simple, eco-friendly and inexpensive system for producing the same current as two AA batteries, which can operate such things as remote controls.

It is very practical if you need to exercice your fingers. I will replace all my AA batteries.
Вентиляционные установки для помещений создают много вибрации, поместив несколько слоев поверх корпуса установки, можно получить немного энергии, тем самым снизив нагрузку на основные электросети
0:36 to be succinct, change "against" to "into", because the effect is to microscopically indent the surface of the paper cards with the sand paper's grit.
This generates AC press/release you could use some diodes to get DC and the screen will be less flashing
what type of capacitor did you use and where is it connected to?
Slick. A larger surface area to increase your current output? And if you run it into a diode bridge? Just a thought or two....
I also try to make the same device but I just have Teflon tape. I made it exactly you said but it isn't worked. The reason for my failure is Teflon tape? I should use the Kapton tape as you ( when you confine the wire with prepared cardboard ).
podrian dar mas especificacion. realice varios prototipos y todos estiman a valores de 50milivoltios, y no registran valores de corrientes. use teflon y palpel como placas triboelectricas y grafito como electrodos. hace falta algun trabajo de nanotecnologia para mejorar la corriente?cuano es el valor de corriente obtenido por ustedes?..muchas gracias!
Could give more specification. Make several prototypes and all estimate to values of 50milivolts, and do not record values of currents. Use teflon and palpel as triboelectric plates and graphite as electrodes. It takes some nanotechnology work to improve the current? How much is the current value obtained by you? .. thank you very much!
That effect thing is similar to theremin. Depends on wet or dry climate too. But may be working like rectantenna. Today we're plagued of lotta WiFi energy
Is your "Teflon" tape FEP instead of PTFE? Self-adhesive PTFE tape is very expensive! And is the "elastic tape" Kapton? It looks like Kapton, but I've heard Kapton tape doesn't stretch.
This appears to be 25mm wide Chukoh PTFE tape. What thickness did you use?
Where can i buy asf110 ptfe?
I have had some trouble finding Teflon tape. Where did you get yours? Also, which elastic tape did you use?
You can buy at your local hardware store in the plumbing section
Did you sand the Card stock before covering it with carbon from the pencil or cover the cardboard before sanding it?
Have you done it na po?
A very interesting project and technique although I had a few questions in mind regarding this................how can I contact you?
sir i want to know which type of tape u r using here ...actually i m using PTFE tape( which is white in color ) and it is not sticking on paper .....please tell me ....send me the list of thing which u r using on this experiment
Good vidéo ! Can you tell me how much generate milliampère (mA) or micro ampère (μA) ?
Too variable even with given size and frequency. But in large part, the average amps will be proportional to frequency and surface area and inversely related to humidity.
How much volt does it produce?
Volts are not power. How many Watts can this device produce?
mW level
Can you store the energy?
Interesting, though I doubt about "same current as two AA batteries".
Same voltage, but not same intensity.
Please someone suggested me the name of the clip he has used. It's definitely not an crocodile clip.
What is sticking at 0:21?
Kapton Tape
Can we use some other tape?
Better not, because Teflon(PTFE) ranks as strong effect in the triboelectric list.
Teflon(PTFE) at -190, Paper at +10 (and eg. Nylon at +30)
dear i made it but it not working ,plz comment on that
isn't Teflon the name of a brand?
I think it is a Kapton
PTFE
@@DiogoRocha kapton (polyimide) ranks at -70, but Teflon at -190 in the triboelectric list. So better use Teflon tape.
is this working?
pls tell me i dont want to waste some of my budget pls tell me thank you....
It is working 100%
en.m.wikipedia.org/wiki/Nanogenerator
There are MUCH better ways to make triboelectric nanogenerators (TENGs) like this. If you make it more like an accordian, it works a LOT better. I have a video I made showing one of these, and I get up to 50 volts.
"3 volts of power.." This is a wrong statement, but the technique is interesting.
+Prabindh Sundareson Thank you for noticing that. We corrected it in the description.
