They claim the tech goes back to Asymmetrical Capacitors which is old tech, but this exploits it in a new or different way
They claim the team members that have worked on this included others from NASA, Blue Origin, and the USAF; of course this doesn’t mean the USAF, NASA, or Blue Origin are invested officially, but some definite heavy hitting organizations…
Much of the same could be said of the EmDrive. This is one of those extraordinary claims which requires extraordinary evidence, especially given the recent history of the topic.
I’m not a physicist, but I’ll try to answer your question:
Gravity, pressure (atmospheric), and a vacuum are not the same; nor are they mutually exclusive.
The Earth’s mass and centrifugal forces are said to exert a total of 1 gravity (1g). While the influence of gravity is scientifically never-ending, there is a distance or limit, known as the Hill Sphere where the effects of a celestial body’s’ gravity dissipates enough that its influence is scientifically negligible. For the planet Earth, the Hill Sphere is about 1.5 billion km or 0.01 astronomical units (AU).
Shortly after the Earth formed, there was no atmosphere and different types of gasses like Nitrogen, etc were being expelled by tons of volcanic activity; much like Venus. Due to the Earth’s gravitational force, these gasses didn’t just dissipate into space; over approximately 3 billion years, these gasses built up and interacted with other gasses / processes that an atmosphere formed. Earth’s atmosphere today is made up of 78% Nitrogen, 21% Oxygen, 0.9% Argon, and 0.1% others. This mixture of gasses, compacted by the Earth’s gravitational force, exerts 360 degrees of 6.9 Kpa at sea-level. At 498.9 km above sea-level, the atmospheric pressure becomes zero
A vacuum is technically space devoid of matter; therefore, there are varying levels of vacuum. Space is said to be 99.999% vacuum because the amount of matter in Space is infinitesimal compared to the size of the Universe.
A hard vacuum (99.999%) on Earth can be constructed by pumping / sucking out the matter from a container, but while the internal contents of the vacuum would now have zero atmospheric pressure, the vacuum and contents or lack of still exists on Earth and is still experiencing 1 gravity. If you puncture the vacuum at sea-level, the 360 degree atmospheric pressure of 6.9 Kpa would force air into the vacuum.
In other words, a hard vacuum doesn’t negate gravity; if it did, gravity in Space wouldn’t be possible and NASA wouldn’t need the vomit comet to simulate micro-gravity. Therefore, when they say they can produce enough thrust in a hard vacuum to overcome 1 gravity, they quite literally are saying that within the vacuum on Earth, they can make an object weightless / move.
Note: Someone else already posted essentially what I did in a much more concise manner… but I already typed all that… so… gonna leave it up for now
If I remember right that is the slang term for a device used to simulated high force situations astronauts are expected to experience. So named for the frequent effect
Gravity and vacuum are not mutually exclusive - you always have to deal with gravity forces, although they become negligible pretty quickly when you get into and then leave orbits.
As to the specific claim, I suspect that the experiments they are currently doing (in vacuum chambers on earth) have gotten to the point that they are measuring the propulsion system producing more thrust than it’s own weight (T/W >1), which would technically be enough thrust to overcome gravity. Even if it wasn’t practically useful for actually getting to orbit, that amount of thrust on a reactionless motor would be incredible, and would totally unlock the solar system for us.

You’re not wrong, but it’s worth noting that in low earth orbit (e.g. typical ISS orbiting altitude) earth’s gravity is still 90% as strong as at sea level. Astronauts on the ISS are weightless not because they escaped earth’s gravity, but because they’re continuously falling.
Not saying its true, because I am skeptical, but a few things I found interesting:

Make it make sense

So in theory if you built a vacuum tube from the earths surface to “space” and sealed it at both ends you could have a frictionless elevator
The… vomit comet?

Oh, interesting! Thanks for explaining.

its* own weight.
And now it makes sense. Thank you!

Ex NASA employees also gave us Depth Dwellers so that doesn’t hold much weight with me.
Counterpoint: Another ex NASA employee invented Super Soaker, so there’s some weight in this
