Plasma thrust is great for (unmanned) spacecraft which are in no hurry to get there...

Typically very, very low thrust but extremely high specific impulse so over days, weeks, months, years, you can get a very, very large velocity change out out of a very, very minuscule amount of fuel.

I'm frankly very surprised that they've built a thruster which has both enough thrust to move an aircraft against drag and is still light enough to be carried by said aircraft. If you asked me yesterday I would have said it was technically impossible. Impressive.

Fanscinating indeed! But will it fly on a treadmill?!?!

Yep... now that the concept is proven it's simply a matter of increasing efficiency and scaleability.

I am however pretty confident that it's a long way off to power big jets... 2-3 orders of magnitude.

I guess we should keep an “eye on” on this technology. [emoji2957]
