If nuclear fusion were to become useful for residential heating, could the plasma be useful for fake fireplaces? (lemmy.world)

When I say “fake fireplace”, I mean something like those structures fueled by fossil methane that produce flame and heat but obviously don’t burn actual wood

And that's why you can get a sunburn if you're welding without proper clothing/protection.

Technically speaking nothing is stopping you from building a plasma fireplace right now, it doesn't need fusion energy. Just grab a stick welder transformer and place couple of carbon rods carefully next to each other. That might be a bit loud, a bit bright for your living room and might set things on fire and have other minor issues like killing your wifi-signal, but it could be done.

Or if you're satisfied with a bit smaller "flame" you can get a plasma lighter from amazon for 10-20€.
