Microwave resonant cavity thruster.

Fuck, I hope the memedrive works...
But it will be a blunder and/or a scam like the Andrea Rossi's cold fusion

>>9157828
Not hard at all-stick one in space and see if it works then. But thats expensive.

>>9157828
Hard. Its thrust is barely above noise levels. And even if it worked in space, knowing the reason is essential because it could just be ejecting trace materials from its structure, meaning it would stop working very soon.

>Its thrust is barely above noise levels
1 milli-newton is measurable and any noise will cancel out.

> it could just be ejecting trace materials from its structure, meaning it would stop working very soon
More like after many many very useful months of use, if you can't even easily detect the material loss.

Suppose it is somehow losing mass. If the effective "exhaust velocity" is close to C, wouldn't that mean it is nearly perfect in efficiency in terms of mass utilization for the
inertial thrust ?

>unidirectional thrust regardless of device orientation
It doesn't work bro

For a trekkie this is ironic on multiple levels. First off it looks like a Vulcan starship. Second off the math says the ship should look like this, which is exactly what the Vulcans would do.

>>9157828
Real fucking easy. Take one, measure its thrust, then put it on the side and measure again. If the thrust is still the same direction, it's a meme.
Oh wait, they already did that ages ago and it didn't hold up.

>>9157828
Just put the thing in a 2 cubic meter sealed box.
Then put it on some sensitive scale contraption to measure thrust.
You don't even need a giant NASA style vacuum chamber, let alone testing in actual space.
The only control missing would be it could be somehow pushing off of earths gravity so it might not work in deep space.
But that would be pretty amazing, in and of itself, if it actually "pushed directly" on earth's gravity field.

I'm going to go with it actually working and government groups and corporations are jumping over themselves to get powerful ones up and running.

What about Earth's magnetic field interacting with the drive ?
I suppose you could maybe shield it sufficiently (in the sealed box) to eliminate that.

That photo shows the Alcubierre FTL drive concept ship which is different than the EMDrive.
