Literally why. I mean cool contraption +1
also pipe instead of metal for electrons (ridiculous, but that's the point)
still wasn't discovered that
you could use liquid crystal instead of quartz to stop photons from getting reflected
the BIZR one in practice is good for photon superreactors, given if it's hot enough, it doesn't even need a film.
i used BIZR based ones because i think it was more consistent?
