Similar to the EM drive... IF this is the device I’m thinking of... they’ve already tested it in a hard vacuum and still got a positive test result.
They are pretty much at the “chuck it out an airlock and see if it flies” stage.
BTW... this would theoretically open up the entire solar system to us as even Pluto would be reachable in just a couple days...
As such, “it’s a big f***ing deal” as our pResident once opined...
There is at least one effort claiming 1G acceleration out of their propellentless device.
At 1G constant acceleration, Pluto is reachable in just over 17 days.
No dark matter/energy required. With already available power sources.
Start to open the box and suddenly barking erupts.
That’s what I would think also, but not my field, so I am not sure what the reality is, and perhaps even those involved are not certain either. Which means that it’s possible that if wrong, it might not be safe for the human body.
And that's where one-way mission cryo-sleep comes in.
I can see a 1G being achieved with a propellent, but sustaining & actually increasing in speed seems unlikely without a propellent.
To me it sounds like science fiction, but since it is not my field I may be missing something. In other words, I am not saying it is impossible, but rather if possible, how is it possible. It doesn't seem that space objects increase their acceleration rates.
We have been taught that space is a vacuum, meaning there is no air resistance or friction to slow down or speed up objects. Which we see with comets that seem to move at a constant speed and movement that they can be predicted as to when they will once again pass by us, which indicates that there is something that makes their movement controlled by some source, wouldn't it?
they thought she returned to china.
but news came out a year or so ago that she died and was buried in Huntsville Alabama. She was preceded by her husband who died about 2016.
Turning at incredible speeds would not be a problem

sounds like what space alien spaceships can do according to reports.
“At 1G constant acceleration, Pluto is reachable in just over 17 days.”
The distance from Earth to Pluto varies. But let’s use the approximate average of 6 billion miles. It would take 11.5 days to travel half this distance with a constant 1G acceleration. Then, you would need to slow down at this rate for another 11.5 days. So, it would take roughly 23 days...
Unless you just want to flash right on by Pluto.
What a waste of money. I see no reason to go to the moon, search other planets with probes, or put up space telescopes. How about cutting spending to govt income minus 10%?
Transfer of momentum in a standard resonant cavity. By this method, hitting light speed is not possible... Since the elasticity of the transfer is never perfect... the imbalance is what causes the motor to move...
That is a highly simplified explanation and leaves a LOT out...
Test results right now have produced 1G of thrust in a vacuum in a lab demonstrator... If it scales up... more could be possible, but then the effects of prolonged >1G effect on human physiology come into the equation...
Even a two month trip to Pluto and two months back would be possible...
That opens up a LOT of territory and resources in the solar system. Even if we spend the next couple hundred years mining out the asteroid belt and Mars...
It’s not a straight drop to Star Trek, but it gets us to that next step up the ladder...
I punched the numbers in to a Google search... The particulars are obviously going to be different.
Considering we have folks on the ISS that are in microgravity environments for MONTHS... 2-3 months at 1G is a piece of cake...
Biologically speaking and at our current tech level.
Wait a minute, there is a motor involved? Is a motor not considered a propellant, even if it doesn't require some form of energy source to make it operate?
Electricity in -> change in momentum out... Energy is conserved...
So... yeah.
EV batteries seem to lose power here on earth at much higher low temperatures.
So, it still remains sounding like science fiction, to me.
Yet... weirdly enough... Even the batteries on the Voyagers are still working even though they are pretty close to being interstellar at this point...
