Super hot plasma made easy with stabilising fibres

CORRECTION: The video incorrectly states that an 'extremely high voltage' is used to create the plasma. In fact the use of carbon fibres in this device decreases the required voltage to less than 50 volts.
In a plasma electrons separate from atoms and create a soup of charged particles that can be extremely hot and bright. This is particularly useful for manufacturing certain types of high temperature materials - and for experimenting with new materials. But plasmas can be hard to control, and existing methods require specialist equipment. Now a new technique using carbon fibres has been shown to be able to create a stable plasma with a uniform temperature - and the researchers say their kit will be much easier to construct in physics labs around the world.

looks like a very significant advancement, to me. 😎👍

I would have liked to have heard quite a bit more detail about the plasma parameters themselves rather than another rehash of what plasma is. Practically everyone knows what plasma is nowadays and especially people watching Nature publication videos. I want to know the luminous efficacy of the plasma, what kind of voltage exactly is being used and what's the total power input? Is it DC current or AC? High frequency or low? What source material is the carbon fiber made of? There are a number of amateur (term used VERY loosely) science channels on here like Tech Ingredients or Applied science that have either created or used carbon nanotubes in novel ways and to whom such an application may be relevant for further investigation.

This is reasonable, but if you are interested, why don't you just read the paper?

Wow cool and so simple. Just a carbon tube sponge and current in an argon gas environment. Brilliant idea.

Great

A deeper dive, please! How can I reproduce this?

Ohh.. wait.. Paywall. :/

[@gsmontag]

I'd love to know if (and why or why not) this could have any application in high-energy plasma research specifically fusion energy?

[@unvergebeneid]

8000K is not nearly enough for fusion. It's slightly hotter than the surface of the sun, not hotter than the core of the sun. And fusion on earth needs _much_ higher temperatures because we can't recreate the pressure of the sun's core.

[@whiteglitch]

​@@unvergebeneid what if we increase the voltage or the surface of the carbon sponges ? 🤔

[@evilkidm93b]

I think you'll have to try it out yourself because nobody knows :)

[@unvergebeneid]

@@whiteglitch fusion in reactors happens at around 150,000,000K instead of 8000K. So that better be some sturdy sponge.

Does this mean that steel can be made easily without reliance on fossil fuels?
