In reply to the discussion: NASA Tests "Impossible" Perpetual Motion Drive; Says it Works [View all]caraher
(6,278 posts)105. I just saw that xkcd
I'm not sure where Randall got the 20 kW figure (I guess it may depend on which experiment he's talking about) and others in the xkcd forum are similarly confused. I have to say that if it's as simple as a microwave radiation pressure there's no reason their writing would be as opaque as it is. And the explanations I have seen of the devices don't really incorporate a "nozzle" of any kind for microwaves to to exit; they seem to be closed resonators.
For me the bottom line remains what the mouseover text hints at:
I don't understand the things you do, and you therefore may represent an interaction with the quantum vacuum virtual plasma.

It kind of is if quantum fluctuation particles drive the engine and are created perpetually .

Yeah, but it still takes energy (electricity) to accelerate the reaction mass..

Correct me if I'm wrong, but these particles are pretty much everywhere in the universe.

Nope. "“Alright!” they said. “We’ll test your stupid drive that won’t work.”

We've known of this phenomenon for a long time as zero-point energy or the Casimir effect
