  1. In an apocalypse, recharging would be a non-issue because I'd be hoarding solar panels to keep my house (and truck) very well powered. Also, ammunition for larger guns could be made from rebar or other scrap metal.

  2.  @KertaDrake  Quiet is a tactical advantage.

  3. Unnecessary consumables + complexity + moving parts + points of failure.

  4. For a useful amount of power, you'd probably need to switch to a ~400V system, at multiple tens of thousands of amps. And also rifle the barrel, which would likely need to be made of some advanced composite ceramic hybrid.

  5. Also consider that this gun is firing with basically zero power compared to a practical weapon. It sounds like a stapler because it has about as much power as one. (40V at maybe a few hundred amps) A real gun (400V at a few tens of thousands of amps) would make at least a solid thump.

  6. Likely need a different barrel material that can be rifled. Certain types of carbon fiber could work.

  7. Rails have the advantage of being easy to design and build, but are lacking in efficiency, and the rails tend to erode and need frequent replacement.

  8. You want to minimize the gap between the coil and the projectile. Also fins are expensive.

  9. Would 10,000 amps at 400V help?

  10. Probably need a 400 volt system, but high voltage is scary. Rounds with fins are expensive. It's cheaper just to make a cylinder with a pointy end.

  11. Definitely need a hardware safety switch that not only disables the firing command, but also cuts 5V power to the modules that switch on the coils.

  12. Likely won't see a true pistol for a long time. No room for the electronics.

  13. Maybe we could have the machine that turns long rods into projectiles put a chamfer on one end.

  14. This is coil. Rail is very different.

  15.  @beerrox711  >recoilless A coilgun with the same power as a given conventional gun will have the exact same amount of recoil.

  16. Need a long projectile to accelerate it properly.

  17. If they choose to rifle the projectile instead of the gun, the bullets would look just like drill bits.

  18. Bus bars would likely be far cheaper and could double as heatsinks.

  19. This. If you can't rifle the barrel, shoot pointy drill bit.

  20. Not really possible to do with normal capacitor making machines. Would cost several thousand dollars per unit assuming production volume is about 500 and someone at the capacitor company volunteers.

  21. Spinning them up would add unnecessary complexity. Just rifle either the barrel or the projectile.

  22. Also massive complexity and reduced power.
