The EmDrive uses a sealed cavity. There's nowhere for any propellant to come out, even if there were any!

sure, the only thing it could do if it remained sealed would be emit black body radiation, and the whole reason this report is interesting is that it's apparently moving a lot more than you'd get from such a result. well, perhaps it could offgas, that's been mentioned elsewhere.

I totally understand what you're saying, and I agree entirely, except when it comes to conservation of momentum. It's a simple concept that is necessary for this Universe to make any sense and be stable in any way.

Not really. There may be well-defined circumstances in which it can be violated, which rarely occur in the "natural" order of things. In theory, planets can make their own functional electronic circuits through ordinary volcanic and geologic processes, in practice... 42, I guess. It has long been observed that the laws of physics seem to break down at very high and very low energy states. If they behave themselves at most other times, then most things will behave in a way that is highly predictable at most times.

An honest question - what is different about G+'s interface or paradigm (compared to Facebook) that gets people to post content that makes you like them more?

I'm not really sure. Somehow G+ seems more oriented towards seeing stuff from disparate sources. I just find more stuff to reshare.

Yeah, I suppose saying something blatantly stupid and arbitrary sounds better if you lead with it with a strained air of authority.

Irony, it's not half the comment you wanted it to be, is this the best use of anonymy? I believe in irony.

But, of course, in no way does it "need" to be eradicated,

That depends on your goals. If you want to move forward, yes it does.

Some time in the future, noise and exhaust pipes will no longer be associated with "power", but rather "wastefulness". That is when electrics really will shine.

That's already how most people feel in most of the world. Big loud exhausts are seen as a cry for help, expensive cars as a penis substitute, etc. And now, all the most aggressive American cars have forced induction. Even superchargers mute the engine note, and turbochargers also quiet the exhaust, so this is the beginning of the end of loud. It will still be a thing, but it won't be a thing you can just go buy off the lot, because emissions regulations will kill it by driving people towards more technology instead of more liters.

I know the Hellcat is kind of a conspicuous counterexample, but they won't likely be able to continue to make vehicles like that much longer, so enjoy them while they're here.

There is significantly less room for electrics here, since bikes can already quite easily be very efficient,

It takes an expensive and/or gutless motorcycle driven gently to be efficient, and it's well-known that most motorcycles have atrocious emissions. That's only changed recently... and it's made them very expensive. That's a lot of motivation to keep old bikes around, forestalling the adoption of emissions technologies. Motorcyclists are in general more reluctant to adopt new technologies, which makes sense when you are going to be rushing along over the road protected by some leather or nylon and a plastic brain bucket and with all those technologies stuffed up your ass. You want to be pretty sure they're not going to blow up.

That said, EVs aren't exactly new tech any more, and yes there are a number of contenders these days, put those things together and you get my GP comment.
