I don’t think the vaccum would affect the drive working. It was used in the experiment to show it would work in a vacuum.
Microwave in a vacuum would not be attenuated and scattered like it would be in our atmosphere. That might be the point of the experiment. But microwave is not like laser energy where it is focused. Microwave can be beamed, but it does disperse over distance. Strange.
I’m still not certain about the legitimacy of the actual .pdf that was linked.
This could be pop science BS article. I’m not sure about it.
The source of the article makes me suspect it is BS.
“Leaked NASA paper shows the ‘impossible’ EM Drive really does work”
“Did we just achieve fuel-less propulsion?”
—
The “Leaked” reference tells me it is nonsense.
The reference to “fuel-less propulsion” is certainly totally wrong. It requires an external source of RF power for the drive to work. It is not free power.
It’s not free energy or perpetual motion. It uses electricity to produce the microwaves. Kilowatts....
actually it really does exist.....
Interesting! Bookmarked
I don't think you understood the article. There is absolutely energy expended.
However, there is no reaction mass involved, or more accurately, you don't have to carry it with you. Other rockets make thrust by expelling "stuff" at velocity out their exhaust. Bad news: you have to carry the "stuff" with you until you're ready to expel it, and it's heavy. This "rocket" may be making its own "stuff" (photons) as it goes, so the "lifting heavy stuff for thrust" problem goes away. That's the big win.
My first thought as well upon reading the article. They are just not looking for or measuring the right thing(s).
All EM waves are composed of photons, but the energy of the photon varies inversely proportional to wavelength (E = hc/λ).
If it’s on a NASA email or computer file anywhere, then the Chinese probably already know all about it . . .
I’m still waiting for that Rossi character to produce the LENR E-CAT gizmo that certain people were shilling for here a few years ago.
From what I’ve read of this drive, it sounds like a fairly simple device that could be made cheaply and put in a small enclosure. I say that NASA build one, send it up to the ISS, and have an astronaut fire it up. It really wouldn’t even need a guidance system. Just point it anywhere and turn it on. If it blasts away like a bat out of hell, then we have a working system. If it just sits there and consumes electricity, then it doesn’t work.
I've seen drawings of the device. It has no port for anything to escape from, unless the microwaves are somehow penetrating the metal base. If they can do that, then you'd need a heck of a lot more shielding for the microwave in your kitchen than the mesh it has on front that allows you to view what is cooking.
Supposedly particle/antiparticle pair production occurs all the time—they form then annihilate in short order—resulting in no net change in the energy content of a given volume of space.
One variant on the reasoning of how Shawyer’s device could work, invokes accelerating these particles during their brief existence, resulting in a minuscule reaction force. The cone shape skews the force balance of accelerating fields acting on particle or antiparticle, creating a slight imbalance of the forces. This out-of-balance condition is designated as thrust.
Do light waves have magnetic components like radio waves?
Or is that because the energy level of the particles are lower or because of the wavelength is more narrow in spectrum?
IIRC, incandescent light bulbs generate photons over a wide range of frequencies, but LED are more narrow.
This is a similar issue to the difference between fluorescent bulbs and incandescent bulbs.
ANY EM radiation can be expressed either as waves with a specific wavelength or photons with a specific energy.
Define "crappy".
