#1. Yes...provided the payload was protected from the acceleration which would be bloody AWESOME.

With all the $ spent on research & development they could have fed the homeless for 20 years.
Oh wait, It's the U.S.super power... wonder twins .. activate

#1. Yes...provided the payload was protected from the acceleration which would be bloody AWESOME, and according to the guy in the video it would reach that speed (around 5,328 MPH ) in 10 MILLISECONDS. I just wonder what the 'G' force would be on that?
I THINK (I'm probably wrong by orders of magnitude)...that it would be around 44 G's, anybody? Sorry...I hit the return button by accident on my earlier post :-(

Probably more like 250000 G

#2 You beat me to it. That guy's expression says all there is to know about the military and their excitement over boys' toys designed to kill.
The best we can hope for is that, like the laser, Teflon, etc. some proper use will be found for it, so the money won't be entirely wasted.
I'm a believer in "knowledge is power" and all sensible science may well find its use one day (and I say "sensible" deliberately to exclude obvious crap like homeopathy).

v= Mach 7 = 2382 m/s
t= 10 ms = 0.01 s
a= v/t = 238200m/s^2
= 24282 g (g=9.81m/s^2)

Yes but.... how long do the batteries last?

sure #14 :
Velocity equals mach 7 equals twothousandthreehundredeightytwo meters per second.
Acceleration-time equals ten milliseconds equals zero point zero one seconds.
Acceleration equals velocity divided by acceleration-time equals twohundredthirtyeightthousandtwohundred meters per second squared equals twentyfourthousandtwohundredeightytwo times earth's gravitational acceleration (with earth's gravitational acceleration being nine point eight one meters per second squared)
Equals severely fucked up payload.
Glad i could clear that up for you!

#17 The batteries last a full 12 hours between charges. The problem is the batteries are the size of a second ship which needs to be towed behind the gun ship, slowing the whole thing down. Also the gun can only be used for projects close to land because the charger is the size of a multi-storey car park.

#21. I prefer #19's more colourful and imaginative explanation. Besides, I just can't take you and your greatly diminished manhood seriously after your last hastily-removed avatar. LOL.
