The idea behind it is pretty straightforward. It takes advantage of Brownian motion and natural convection to deactivate biological hazards like active viruses/bacteria/myceliums' spores.
It works by radially spreading a collimated ray of light thanks to a cylindrical glass. Due to the costs of EUV-UVX-UVC lasers, ideally, the glass has to be coated with a band-pass filter, to emit radiation frequencies ranging from 254nm to 261nm (the best at damaging DNA/RNA). By doing so, cheap laser sources with a noisy spectrum can be used.
Preferably, 4 are needed for a door. FFC/FPC wiring is the ideal solution to transfer energy to the device if wired. Wireless power could be an alternative. Doors' frames are a mere example;a spiraling tube that's traversed by the barrier can cross it many times.
Possible applications include door frames, room separators, transportation, farming, space, air filtering, water treatment.
