In 2001, British Electrical Engineer Roger Shawyer first introduced the “impossible drive,” known as the EmDrive. It was called “impossible” because its creator purported that the drive was reactionless, meaning no propellant required—in other words, it defied the known laws of physics (specifically, the conservation of momentum).

The 2001 version went nowhere.
The 2023 version is being validated.
Wake me up when it’s ready for prime-time. I imagine it will show its face on the military scene if and when it is.

The problem is all these claimed reactionless drives are claimed to produce really small amounts of thrust, making it very difficult to measure whether or not they're actually doing that on earth.
If they tested these things by launching cube sats into space, whether or not they actually worked would be much easier to determine as you'd quickly notice a change in orbit.

Interesting. looks like the ark drive.
Actually, there was a magnetic engine that worked well for cheap.
