Particle Accelerator ion guns....personally I find phasers more effective when getting offensive in rush hour traffic...and less mess for the county to clean up...*smirk*
Crystals....this smacks of putting razor blades under pyramids to sharpen them or keep them such. Ionizing a room doesn't strike me as terribly healthy either. Plasma speakers do just that, and although nifty to hear and conceptually interesting (point source, and all that...), I'd only do it in a very well ventilated room.....
Ionized air in nature occurs around strong thunderstorms. I've had the privilege to be a witness and behold such, just before a bolt struck +/- 100 yards away. Granted, that was positive ions I felt. Negative ions do have noted better qualities, and follow such events. I chalked that up to not being struck....
Long term exposure to negative ions....eh, suggested by MD's for depression...might be useful if your current system depresses you. *L* That could lead one to think that such an application 'makes things sound better' if only between one's ears and not in reality....
Waterfalls generate negative ions, which may be a reason we humans find them delightful to be around. Not a practical thing to have in one's listening space however....
One could buy a NI generator....would it induce 'noise' into the AC current? Dunno...but you are messing with a high voltage widget, much like fluorescent or neon lamps...
'Ell, give it a go, let us know what happens....
The only other crystals beyond the benign ones (salts, diamonds, etc.) is crystal meth which should be avoided unless you'd like to avoid sleep, think you need to get
a
lot done, and want to thrash yourself in the process...
