>>7640898 I don't see why they can't whip one up and strap it to a satellite or some kind of fairly simple probe and give it a test run
Like keep testing it sure, but multiple of these things have been made (since multiple places are testing them) so surely it would be worthwhile to actually field-test one and see if it holds up outside of a laboratory setting.
>>7641193 /sci/tards confuse lack of funding with lack of interest. They think scientists are "avoiding" it when in reality they would gladly test it if they actually had funding, some of you are completely unaware of just how stagnant space research is thanks to budget cuts.
Well, the EM drive is getting measurable thrust from radiation pressure. In effect, they've created the worst solar sail. Your exhaust may be going the speed of light, but you'll be some 8 billion years into your flight before you're even a small fraction of C.
Hope you remembered to pack a lot of fissile material 'cause we're going to be here for a long time. At least that probe is going to put a really big dent in whatever it runs into in the next galaxy over.
tl;dr That EM drive would yield a high top speed, but its acceleration is the worst.

Solar sails are only a good idea because they're using radiation pressure generated by a star. Unless you've somehow managed to cram a fusion reactor that big into your little spaceship, you won't have left the solar system before something better comes along.
>>7640898 I don't see why it couldn't work. Space is full of electron-(negative)positron pairs, you just need to push against the particle with the positive energy to thrust yourself forward. The only downside is that the negative energy somehow has to be compensated for, so either in form of the photons that travel through the em drive disappearing from existence or the em drive itself losing mass/temperature.
>>7642908 >"Captain, slingshotting peas against our forecastle turns out to be terrible propulsion" >"USE MOAR PEAS!!!!" Would this sort of thing actually provide ANY propulsion at all? I thought any kind of reactionless propulsion (that doesn't interact with something externally like the sun) is impossible according to physics. And what's all this talk about the EMdrive being a solar sail?
>>7641349 With all the dumb shit that gets funded on indiegogo/kickstarter, I'm sure if they asked they could get the money they needed from crowdfunding.
I mean people were fucking dumb enough to fund a fucking statue of robocop in detroit, and the memedrive is every popsci le nerd XD's wet dream so I'm sure they could do it, and hitch a ride up on an ISS supply mission for relatively little.
