How do they plan to deal with all the ozone that will come off of those plasma speakers? I've made a plasma tweeter in the past and it sounded excellent, but the ozone it produced made it rather unhealthy to run for long periods of time.

Can the ozone be countered by a reverse polarity static charge? Not sure how the laser printer do it, but recent printers barely emit ozone. I think it should be possible.

Best thing would be to run it through am activated charcoal filter. That would catalyze (I think) the O3 to O2. Even HEPA filters would have no effect on ozone, as it's a molecule made up of 3 oxygen atoms.
