Hi All,

I searched through the patent databases and came across a patent which explains the effect of heating capacitors.

Patent# 3147390 "THERMO-ELECTROSTATIC GENERATOR" 1964
http://www.freepatentsonline.com/3147390.html

From patent:
"...The dielectric material changes its dielectric constant with changes in temperature so that the capacitance of the capacitor referred to above also changes with temperature.

By charging such a capacitor through suitable conductors connected to the coatings to provide a voltage across the capacitor while the dielectric material thereof is at one temperature and then changing the temperature of the dielectric to decrease the capacitance of the capacitor, the voltage across the capacitor is increased so that a greater increment of electric energy can be withdrawn from the capacitor than was originally delivered into the capacitor during charging.

This involves a conversion of heat energy into electrical energy..."

HI all just noticed something interesting with this captret effect was messing around and knocked the charged capacitor hooked up to led via top and the led flashed Bright and when tapped continues to flash bright...... checked and all caps ive tried on so far seem to react the same...

is this creating more of a "short" to metal can of cap and could this possibly explain this captret effect??

havn't tested resistances and such while 'tapping' cap...

any thoughts people

Hi,
I have recently bought 100 pieces of 0.47 uF ceramic Y5V
caps from
www.segor.de
but had no time yet to solder them together yet.

But will do soon.

Here is another guy who seems to have used this principle:

http://gigawattave.org/

And he also shows in 4 videos, how it works and that it will
deliver more energy, when heated.

Here is his youtube channel:

http://www.youtube.com/user/eye75goat


So these ceramic caps are great cheap thermo to electricity converters.

Regards, Stefan.

So, we could paint these flat black and stick them outside in the sun and get more power?  This is great.

Hi Bill, All,

There is a patent that has an interesting arrangement for using two variable caps and feeding it through a transformer. By shifting the dielectric state back and forth causes it to oscillate putting power through a transformer for the load.

So an idea to test is maybe heat one cap while cooling the second. A small dc motor low rpm with a round cardboard attached. Shade one cap while the other is exposed to the sun.

Patent# 4087735 Solar electric generation using variable capacitors.
http://www.freepatentsonline.com/4087735.html

Fig 1C shows the flow of current as the dielectric changes.

Fig 2 shows if you put a transformer between you can cycle the energy back and forth while still running a load.

I think,
we could just easily build a battery charger for e.g. 12 Volts Lead acid
batteries by using such a Y5V ceramic capacitor bank and apply
a fresnel lens to it and heat it up via sunlight.

The put the cap bank via a relay across the cap bank and
the cap bank will charge up to 12 Volts.
Then interrupt the relay so the voltage can rise on the cap.
WHen the voltage is about 30 Volts, just connect again via the relay
the cap bank to the 12 Volts battery and it will deliver
a huge current spike, until the cap bank is again at 12 Volts.
This will charge up the 12 Volt battery.
You only have to make a timer circuit that toggles
the relay every few seconds or minute or so.
So this  is pretty easy to do.

@ hartiberlin

I was researching the ceramic capacitors you mentioned and found the model Y5V here in North America at http://parts.digikey.ca/1/1/1353195-cap-cer-100uf-16v-y5v-2220-c5750y5v1c107z.html

Can you confirm that this is the capacitor(s) you are talking about? 

The price break is very expensive for 1 unit compared to 100...would make sense for people to make a large order...

Price Break    Unit Price    Extended Price
10            6.29000   62.90
100           3.71680   371.68

But still $ 62.90 isn't the end of the world for a small project.  10 caps @ 16V into a battery or into the "Patent# 4087735 Solar electric generation using variable capacitors.
http://www.freepatentsonline.com/4087735.html" that DreamThinkBuild mentioned.

Can we hook these puppies up to our collective PC CPU's....LOL...you know that might just return enough energy to cut some of our power consumption down.... :P

Paul

Hey guys, just a quick hello and  thanks to ibpointless2 for sharing his findings with his captret idea.
His work has re-inspired me to go open my box of old wires , capacitors and batteries and tinker some more.

I don't normally get much time to tinker due to work committments, but I thought Hey WTF it's Easter and I find myself knocking back a few ales with some time on my hands.

I started off just charging a capacitor and discharging through the captret as ibpointless2 shows in his videos, waiting some then discharing the cap again. Interesting concept. So I thought get some high voltage capacitors - a few hundred volts will do - hook up the captret part to a spark gap and adjust so it fires off itself when the captret recharges itself. I dont know much about this phenonmenon but it feels to me as if shorting something or using a spark gap excities this energy - or starts the pump going so to speak.

It seems this energy is intelligent, and seems to react to my state of being. It could be the ale talking but I have noticed that in certain moods (thankfully im a good one most of the time) - eg bad mood. I cant get this affect to manifest.

Which brings me to my second and current experiment.

2 x dead 1.5 volt batteries (non rechargeable type)
2 x 40v -5600uf caps
super bright white led. (The one that hurts your eyes when it's on bright)

I'm not exactly sure of the white led specs but I think it's a 3v 50ma one. when I connect it directly to the batteries in series - reading 2.85v it barely lights up.

I started off using 1 cap (5600uf in captret style) using the led, the light lit brightlly but was draining the battery.
Originally my combined battery voltage was 3.06v, and after stuffing around with the captret leaving it overnight it was down to 2.85v. Time frame 9 hours.   0.21v over 9 hours - or 0.023v ever hour. When I woke up my light still had the same intensity though just now reading 2.85v.

So  I added another 5600uf in captret style to the first cap and repeated the experiment.
Started experiment @1pm. I had to go out so I left it running. Keep in mind no meter was connected to it. I just connect it when I take a reading.

Came home @ 4pm - circuit left running for 3 hours. Retested batteries - were reading 2.85v. Led still at the same light intensity (hurt your eyes bright) batteries cold to the touch. Led not giving off any heat - luke warm if that to the touch. Seems the batteries are not discharging or charging. will have to wait and see. but quite promising so far.

circuit still running as I write this. want to add another cap to see if this will make it charge. Went to electronic store to buy more alligator connection but were out. bought more booze instead. will keep posted.

Thanks for reading, have a great easter :)

You have a small solar panel laying around?  It would be interesting to see if you get any good voltage out of the bright led with your setup. 

Happy easter and experimenting.

I do have a small 2v 200ma solar panel and did try to see wat I could get out. unfortunately I could only get around 0.2v from it.
The panel's glass is not flat which probably isn't helping either. I'm hoping to get enough lights going in a formation that I can sit a panel on and power something else off it.

Update on other experiment. (2 captret setup) - Left running 20 hours.
starting voltage 2.85v - End voltage 2.83v.
I am still running this setup, however I have now added a 3rd capacitor to see what happens. starting from 2.83v

Just for interest I have a brand new 6v Lantern Battery I recently purchased which reads 6.53v
I thought it would be nice to have a control, so I grabbed another one (as in an identical one from a pack I bought) of my super bright LED's and just connected it to the battery.

Here's some results

3 cap captret started @ 10:10am reading 2.83v
control led on 6v battery directly connected started @10:45am reading 6.53v

Took a test of both @ 11:18am
3 cap captret steady @ 2.83v after 1h and 8 min run time
control setup battery down to 6.29v after 33min run time.

To be fair, I'd say that the control LED was probably a little brighter than the captret setup for the first 5min, but after that time was not as bright as the captret setup. (Keep in mind that both LED's both very bright though)
Differences - control LED was exhibiting a blue glow. The LED was very hot to the touch - close to burn my fingers hot.

3 Cap setup LED was brighter - it did not diminish in intensity at all. LED was exhibiting a white glow. The LED was luke warm. minimal warmth coming from touching the LED.

Well, definately other things going on there. that's it from me for now. More experimenting ...

 :) Hello. :)

I've played with captrets for a week now. it seems to me it's a 3 plate capacitor. But I don't understand exactly what is going on.

I was able to verify the "memory effect" reported in the CAPTRET (after using a capacitor as CAPTRET, it self recharges quickly). Self recharging is surprisingly strong. But if you plug a load to use the memory effect as power source, it vanishes after some hours. It's very interesting.

A capacitor shouldn't conduct DC. But when plugging a LED to a CAPTRET like circuit, my multi-test can measure current flowing from the battery's negative to the capacitor's shell. But if it's a 3 plate capacitor, I shouldn't have any DC current!!!

It might be a problem in my measurement device (multi-test). I suspect it works using voltage potentials and not really current. I don't know.

My question is: how can current flow from the battery's negative to the CAPTRET's shell?

:) Please continue your excellent work.  :)

The third plate is actually an energy at the outside effect of the two energized plate, since one plate is always not i use so it always make the other one plate to complete number of electrons by pulling at the outside and at the same time make a flow at the third plate.  8)

It always makes pulling effect to sustain the other plate and make flow to the third plate.

conclusion: FREE ENERGY  :P

Hi Tito.

 :) Thank you for your reply. :)

The current I get flowing out from the battery is exactly the same that flows into the LED. I've got 2 multimeters to verify and the current flows up and down at the very same time at the very same number.

It seems to me that, instead of reducing voltage, the captret reduces current keeping voltage. That's why it works so well with so called "dead batteries". By the way, captrets are giving new life to dead batteries. I found myself searching for dead batteries. It is of great importance if you can give a new usage to so called "dead batteries". It's economically and environmentally friendly. I would suggest commercial use of captret in flash lights because it efficiently uses dead batteries.

Getting back to the subject, because I see the same current from the battery and into the LED, I'm not seeing free energy nor free electrons. It seems that the external shell some how is connected to internal shells through a resistor. And I'm seeing a voltage drop across the capacitor like a diode would do. I'm not quite sure if I understand what you've written in your last post. In the case you can detail, please do.

Do you know what causes the memory effect? I was able to get both positive and negative "memory" behaviours.
