noble gasses next to a Tesla coil
@yogthos these are not all noble gases, hydrogen and nitrogen are not
@yogthos Where's Rn?
@yogthos that's awesome!
Noble gasses: Hydrogen
Yep seems legit
Really? I always thought, that helium is a transition metal.
Very exciting demonstration!
Incidentally, those gasses are at low pressure in those ampoules.
Wonder what a tesla coil would do near an old plasma tv. Probably excite it to white, or nothing at all (transparent front electrode).
@yogthos I've seen this before but I will never not share this!
@yogthos Why isn't nitrogen used for lighting? In this clip it looks like it glows even brighter than neon, and it's loads more abundant
@yogthos I guess it's better to ask past-tense, "why hasn't it been used"
It wouldn't be used now anyway because LEDs are so much more efficient, at least I assume. But also I think those curlicue bulbs were full of argon, right?
@socalledunitedstates @yogthos Efficiency and If you want to have any form a radio communication near it doing it like that would be a bad idea. What excites the gases in the video is the strong alternating electric field. The glas basically acts as dielectric forming a capacitor (the gases on each side being the electrodes). You need a rather strong field for that to work, which in addition to causing wide band radio interference will damage any electronic device that gets close enough.
@socalledunitedstates @yogthos If you have electrodes inside the a low pressure gas, you need a much weaker field to get it to light up.
Looking at the arcs I'd say that tesla coil should produce around 15-25kV. (Mine had similar arcs and I measured it once).
Your standard office ceiling neon tube runs on 230v after an initial kick with a few thousand volts from the starter circuit to get the electrons moving.
@yogthos yo krypton, calm the fuck down
