Next in the "Can Plasma?" series: can plasma work without any heat? Yes. And it's the whole business case for most modern industrial plasma. The trick is timing.

00:00 The question: most plasma is hot. Can it work without heat?

00:11 Three points: thermal vs non-equilibrium, how we generate it, and the business case

00:29 Callback: there are 4 temperatures in a plasma

00:41 Translational, rotational, vibrational, electronic

00:49 What normal people mean by "heat" is only translational

01:01 Engineers can control which degree of freedom the energy goes into

01:26 We want energy in vibrational and electronic modes: high reactivity, low temperature

01:34 That's how we process materials at low energy input and high output

01:42 Thermal plasma: all 4 temperatures high and in equil ...
