Thanks for the tip Charles, we are interested.
The idea of an array of LEDs meets one ot the design themes for encompassing
a vortex without disturbing the physics behind it. We have been testing some
spiral shapes in the form of thin gauge spiral wire springs that hold the
possibility of avoiding upsetting the vortex while being located within.
Thinking about tiny arrays of LED tuned to UV spectrum give me a thrill.
A cheap power LED array engineered to shine at 285 nm UV would get part way
to making O3 in situ referring to earlier discussion. GaN may be the
appropriate LED material.
Aloha,
Charlie
