So when is the part where the space debris comes flying round and George Clooney has to save the day?
You know how to fuel a car but what about a rocket:

Can't they just send it to space and test it.
Interesting stuff. It's be nice if this turns out to be unknown physics.

Heard about that a while on a few of the pods I listen to.
Nice to see nasa and the international agencies are making the appropriate noises.
More amazing reading through the article over science alert, the amount of on world applications of the em drive. It works all the stuff they mention, needs to happen!

Another tick for the EM Drive
Makes for an interesting (and hopefully optimistic) read: Link is about 7 hours old.

let's just hope it scales well as iirc the previous version was producing micro Newtons of thrust. Somewhat worrying that the brightest minds haven't figured out why yet lol.

Isnt this just the same physical reaction that makes solar sails work, the idea being that just because the particles emitted dont have mass doesnt mean they cant transferr energy.
The big issue is really that this thing will produce such little power yet require a lot of energy to acheive it, not exactly effecient

They have no idea how it's creating thrust. And it's not spitting anything out the back.
Also it's extremely efficient as it's not using up anything. Power and low thrust isn't an issue. There's plenty of power in space. These could be used for orientation and position keeping thrusters, which have an unlimited fuel supply.
Or you could launch a probe with a nuclear reactor and let it accelerate for years or decades. as sunlight gets to faint once you get out to the outer planets.

Indeed,
Power isn't the problem. Propellant/Reaction mass is the problem!
Consider a traditional solid core NTR, the reactor would have enough "Fuel" to operate for months if not years, However the rocket would likely run out of "Propellant" within 10 minutes.
An EM drive doesn't need propellant so will work for as long as you can provide it with electrical power, which might be for decades or even centuries!
