@Izod517: As well as the other way around. Shooting accurately is too easy if you're all sober. It's like resistance training.

@Badlands99: Not entirely true. 12 states of the union (+ DC) require a permit to purchase. 38 require absolutely nothing other than proof of age and a background check.

@Brian Alexander: If you're from the good ol' US of A, you don't need a gun permit to own any handgun. Anywhere.

@ifandbut: Yeah, I'm not knocking the concept entirely. I'm just not sure how useful it will be to us now, but that's never a good reason to stop developing something.

@Gigglebox: When in Rome...

@admoseremic: I find that opens up the crowd behind me, and not in front.

@Curves: Yes. Wait!.. I don't kno-Aaaaaaaaaah........

@psychiccheese: Teddy would be half proud of you.

@aec007: I prefer to just yell "Everybody moooove!"

@ifandbut: But what I'm saying in my OP is that even for unmanned this is unreasonable in its current form. The acceleration portion would take months. While that seems like a small price to pay to not have to carry fuel, once you reach escape velocity, you need very little fuel to propel a craft towards Mars. A…

@ManicSquirrel: Statistical Mania: It does.

@Dane Gonsalves: Few Android phones are updated more than once a year OTA.

@matcintosh: Note the use of the word "average".

@ifandbut: Yes, but I'm guessing that this exercise was merely a proof of concept. The rate of acceleration would likely be so low as to render it useless for manned travel of any kind.

@lemke: I'm thinking more Johnny Depp.

Now I can make grilled cheese sandwiches in scrubs and pretend I'm George Clooney!

Attach this thing to something with any significant mass to it, and you'll have a craft that will take longer to accelerate to c than it will take us to develop FTL.

@Squalor: Well, there's his rifle and his gun. The rifle is for killing, and the other is for...well...fun.

@p4w4rr10r: You can't escape Phil Collins, he's in too deep.

@MikeSWelch: Or an extended or extra battery, or both, because you can.
