free energy for free (Piezoelectric)
« on: July 14, 2006, 08:16:02 PM »
To anybody remotely interested,
       I am a master of physics graduating 2000 A.D at the University of Kent at Canterbury. While I was doing an experiment in my granpas garage, to see if I could use the piezo electric effect to seperate the charge carriers in a semiconductor, I stumbled across something interesting. The idea I had failed to show any meaningful results (possibly due to poor equipment). However I left one of the piezo electric quartz blocks in my grandpas vice under pressure. My volt meter was registering 10 mV +/- 3, across the x cut faces. This voltage across the surfaces of the crystal will not deplete. I had already done this experiment at Graham Deblins precission engineers, Margate Kent England. I offered them this idea for free. Unfortunately Graham Deblins precission engineers has gone bankrupt and no longer exists. The experiment consists of short circuiting the x cut faces, so the voltage across the crystal becomes 0 volts. Then without changing the pressure the crystal is under, removing the short circuit. to my suprise the voltage across the x cut faces returned to 10mV +/- 3. As a matter of fact I can safely say that unless my voltmeter is giving me seriously eronious readings that you can short circuit the x cut faces an infinite number of times with the voltage returning on removal of the short circuit. If my voltmeter is not lying to me, and the experiment can be scaled up ( which it probably can't seeing as perpetual motion machines can't work via the laws of physics), this could provide a new means of generating vast quantitees of electricity. Forgive me if this is old news, or horribly flawed, I just can't find any information about it anywhere.
                Yours faithfully
         Mr D.R.Gillan (Mphys)

test the voltages also with an small LOAD-resistor  (as 1 K Ohm as example)
so you are shure that the piezo deliver  an small energy  (and possebly not mesured some static voltages).

I'm quite sure I measured static voltages, the nature of the piezo electric effect is such. Are you suggesting I short circuit the crystal with a 1 kilo ohm resistor ? woops sorry, ignore my question I'll try shorting it with a load........

If there was a potential difference (voltage), and you short circuit so the voltage drops to 0, a current must flow through the short circuit to equalise the voltage. In the case of the crystals say with both crystal surfaces covered in an ohmic conductor, you have a situation analagous to a capacitor. if you short the terminals of a capacitor a current will flow through the short as the capacitor plates equalise the voltage. The capacitor then needs to be recharged. In the case I outline in my original post the removal of the short circuit is enough to recharge the plates of the capacitor.

Hey DanyG, don't give up on the perpetual motion ideas yet... check out this thread http://www.overunity.com/index.php/topic,1230.0.html
We believe that the individual with this machine may have just cracked it - and according to him, it was something very simple... While I can't really speak for him, I'm sure he would value your input as a physicist on this.
As for the quartz...for scaling up on this, how large of a piece of quartz can you get? and how much voltage could you reasonably expect from a larger crystal?

well larger quartz crystals are used in industry to produce mega volts, I should imagine giga volts are not out of the question. The question is how high a frequency can the crystals be shorted and through what kind of load, amongst other things. I just don't have the equipment to iinvestigate further, or the resorces to research further into why it doesn't work. I assume it doesn't work because the idea is so blindingly obvious.

1kohm was think vor piezo (used in lighters  2000Volts)
older grmmophon pickup cartiges (200mv)
piezo microphones  50mV

If you use static Voltages from crystalls
(unknow to me) , but if Voltage over 100.000 Volt
must be "loaded" , use 100 Meg ohms and more.

Cheap avaiable resistors up to 30 Megohm , you find in ols TV-Sets.

Also , high resistor value > 1 - 100+ Megohm you can make self
with pencil paint (use:graphit-pencil) on an paper  (connectes wit alligator-clips)

 ;) Just to help you a little, maybe the tension you mesure look like thermocouple effect. Simple explaination is 2 different king of alloy if they touch each other will generate a specific small tension like this one with temperature. We use it alot to make temperature sensor.

The trouble is they make VERY SMALL CURRENT, then no power...

Well, it certainly seems like a good idea. From: http://en.wikipedia.org/wiki/Piezoelectric

A similar idea is being researched by DARPA in the USA in a project called Energy Harvesting, which includes an attempt to power battlefield equipment by piezoelectric generators embedded in soldiers' boots.

Wouldn't quartz between two large magnets be under constant stress?

if it give only (high) voltages and no (or small) currents.
it give no (small) power.  Volt x Amp = Watts

If you will see the (peak) voltages that comes from piezo , induction enz.

charge an small condensor via  an (fast) rectifier diode.
