Captret - Capacitor and Electret

[DreamThinkBuild]

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of the capacitor, the voltage across the capacitor is increased so that a greater increment of electric energy can be withdrawn from the capacitor than was originally delivered into the capacitor during charging.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:

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

Here is his youtube channel:

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.
