Can someone please read this and explain how it works.

Thank you.

NASA Confirms the "Impossible" - Propellant-free Microwave Thruster for Spacecraft Works!

Was reading about this the other day, nobody's 100% sure that it does and it appears to break the laws of Physics (although the inventor claims it doesn't) He hasn't put any papers out in a peer reviewed journal and the Chinese Scientists who confirmed it worked first have been rather coy recently.

As for how it works my memory is a bit ropey but it channels the microwaves using the special shape at the back to produuce thrust but as someone else pointed out the microwaves bouncing off the side walls should produce the same thrust or something like that.

Quote from the article;
Now a team at NASA has tested the Cannae Drive developed by U.S. scientist Guido Fetta.
Cannae drive?!?!? Really?!?!

Cant see why it would need all those nylon gears on the back of it , and why NASA would sit it on some old ofcuts of wood .....

How is the microwave energy produced?

The Standard Model of Cosmology has changed with the theory of dark matter/energy which they now think makes up 95% of the mass of the Universe as opposed to only 5% from the galaxies themselves. Hard to accept along with all the other stab in the dark theories that try to explain the theory of everything, but though they can not identify it directly, they can be pretty sure from the effect that it has on stars/galaxies.

That would make it possible to design a drive that would use this inexhaustible supply of free energy to provide thrust that could drive a spaceship and give it continuos acceleration. As it is existing energy and not being produced from nothing, there would be no conflict with the the law of conservation of momentum, i.e. you don't get something for nothing.

Solar panels connected to the same sort of thing thats in your microwave oven I suspect.

You can't accelerate continously as the faster you go the heavier you get, the heavier you get the more energy you need to accelerate.

However there is nothing in theory to prevent you accelerating UPTO the speed of light, that is when mass becomes infinite.

Sort of... objects appear to get more massive (not heavier...that requires a gravitational context) as they accelerate, but only to external observers. Time slows down for the object itself as its velocity increases, and so any forces applied to it appear to the object to be applied over a shorter period of time. External observers see the same force applied over a longer period of time, which makes the object appear to resist the force, which we model as an increase in mass. Really, it's a relativistic resistance to change in velocity and the mass is constant. Not a practical distinction, but I think it's an interesting one.

Anyway, continuous acceleration still works on objects of mass within the relativity laws. It really only hasn't worked in practice because of the fuel inefficiency when carrying your own fuel source. The more fuel you carry, the more you need to shift it.

If you can harvest your fuel as you go, and don't require a constant or minimum rate of acceleration (both of which decrease efficiency), it's not a bad idea in theory. Even better if you don't care about slowing down again at your destination (e.g. deep space probe).

Not saying it works, just that if it does, it has practical use.

I presume this differs from the ion / impulse drive thrusters that utilise very small amounts of charged gas particales, excited by microwaves? They are probably a much more practical method of propulation given their thrust advantages, while still requireing a much smaller fuel capacity compared to traditional thruster systems.
