coloumb force piezo electric generator
« on: January 31, 2009, 03:23:59 PM »
   If a large capacitor was designed to induce pressure on a piezo electric transducer of significant size.  Upon charging and relaxing the charge would the piezo convert the columb force to electrical ouput?  The capacitor could be used in a resonant electrical fashion of high Q and the resultant piezo electric ouput would not appear to dampen the oscillations while generating voltage well over that needed to maintain the oscillator.

Lol,

In recent times I really seem to be the bad ass  ;D (well maybe also, for currently I'm quite in pain...). But there are quite some topics, even older ones, wherw I am astonished, that so many people here seriously discuss about it, without really having understood the basic principle of operation.
One example is the piezo-electret. In one of my first posts I already tried to describe here, how exactly a piezo does work (http://www.overunity.com/index.php?topic=4147.msg99452#msg99452)

So from this understanding of a piezo, you will immediately come to the conclusion, that all the energy that you will get from your piezo, will also be drawn from your capacitor in your oscillation circuit. You can easily do the math...

Nevertheless. Don't feel disinspired by me. Every idea is a good idea. And if some ideas have some theoretical problems, we should indicate this one another. Otherwise discussing it wouldn't make sense...
