Hi Dave,
Well, thats one of the things that is odd about Meyers design.
About the source for the 250 waves, well, that depends on the source. Some have a wide frequency ange from below 200nm till whatever.
For sure, Stans patents and pictures show nothing usable, except for the idea it self. Red LEDS doing what? Much to low on power to be able to do something usefull!
Tubes doing ionizing air? In which century?
Google on ionizers and you find what you need...
