What does PNN stand for?
It stands for Propulsione Non Newtoniana (Italian, meaning Non-Newtonian Propulsion). A group of Italian people claiming that they have a
propulsion system using no reaction mass. Something like a microwaves bouncing around in a closed cavity that they claim, without explaining
the physics behind it, that it produces acceleration. They have video
showing that it gives if I recall correctly some 200 mN of force. We
tried to explain to them that because their microwaves heat one side of
their apparatus more than the other side, the air is heated more on one
side than the other. This differential in air temperature can explain
the force that they measure, therefore, outside an atmosphere it
wouldn't work. But they don't want any of that, they are sure that their "invention" will revolutionize rocketry.

Transmitting electromagnetic waves using a directional antenna produces
a net force. Not much of one, for sure, but some. It's a kind of photon drive.
But it's still not mass-less, because the photons that form the electromagnetic waves have mass, and the attached craft is losing mass
in proportion to the energy being radiated.
Near a star, the required energy can be collected using solar panels,
but solar sails of the same area work better.
So there's a reason we don't use photon drives.

May not be a problem. The Google Groups gateway to usenet is now
turned off, I believe, and these people were too sophisticated to use a
mere newsreader.

I would be interested in hearing about progress and experiments which
have been conducted, preferrably without added raspberry sounds.
