Ultrasonic heat engine

Harmonic waves change heat to energy
 (-1) [vote for, against]

With a small amount of energy, induce ions into ultrasonic tremor. Introducing heat, it will be converted into patterned movement (or at least much of it will) turning heat into energy. With a coil in the vicinity this could be converted to electricity.

and then there is this... http://www.bbc.co.u...k-scotland-17770739

well, well, quantum well. http://www.newscien...uters-scale-up.html
not for producing power, but interesting [4whom, Apr 22 2012]

What's the frequency Kenneth?

 What?

 So, as far as I can make out, the idea is to heat up ions (random movement), and then superimpose an ultrasonic back-and-forth vibration on them. Then use the movement of the ions to generate electricity.

This makes no sense. The heating will have no net effect on the motion of the ions (ie, it will just add a random component to their movement). And any energy (presumably electrical) which you can "harvest" from the relative motion of the coil and the ions will necessarily be less than whatever energy you put in as "ultrasonic tremor".

Let us count the ways in which this will not work...

That would be rather like counting the ways in which a transitive verb will not catch fire.
 — MaxwellBuchanan, Apr 20 2012

You know me... I take that sort of statement as a challenge.
 — Alterother, Apr 20 2012

Let's see:
1.Heat is not patterned movement. Heat is random movement.
2. There are positive and negative ions, adding up to no charge.
3. What <MB> said.
4. Assuming the ion mix you're talking about is liquid water, the frequency with the highest absorbence is infrared light (about 3400cm-1) or 63.2 gigahertz . Building a rectifier to use power at that frequency would be difficult.
5. No cats
6. Reminded me of "The Core" (movie)

#6 alone is grounds for summary execution.
