0:20 This is a coil gun ([not a] Gauss cannon), it's very different because it uses the single force vector created by the coil you'll show later in the video. It's easy: if it has wire going around the barrel it's a coil gun, if it has wire on the back only, and a hollow rectangular barrel section (formed by the rails and the bullet containment) it's a rail gun

In 00:30 the gun shown is a Gauss gun aka coil gun not a rail gun. Its a completely different system, gauss gun uses a series of electromagnetic coils that activate in a syncronize order do propel the projectile. In a rail gun the projectile completes the circuit in between two rails, one rail being + and the other being - and the positive rail is fed by capacitors. This generates a huge magnetic force that pushes the projectile. Two completely different systems.

I wonder if we'll see more of the coilgun start to overtake railgun interest. IMO the main issue of the coilgun (synchronized switching and stabilizing the round in the magnetic field) is a *lot* easier to overcome than the rail ablation issue in railguns. Apparently the Chinese Navy has gone down the coilgun route and is test-fielding a naval gun? Research follows funding, so I guess we'll find out once the check-writers recover from the failure of the US Navy's railgun program.

It should have 2 separate adjacent barrels. 1 barrel for the projectile and 1 barrel for linear motor, so that heat from linear motor barrel doesn't affect projectile and its barrel. Both barrel has lateral opening. Linear motor pushes metal that has leg in projectile barrel to propel the projectile. This will be fine as there is no explosive propulsion in projectile barrel. Projectile barrel can have holes to dissipate friction heat

It's not friction that's destroying the barrels. It's the dead short created when 25 MW are applied to the conductors with the projectile contacts closing the circuit. The (nearly) instantaneous surge melts and vaporizes portions of the rails.

It fires a projectile at very high speed much faster than a conventional artillery gun. At that speed, you don't even need gunpowder as the velocity of the projectile is enough to obliterate the target. This also gives it a high range. Only issue is that the heat produced literally destroys the barrel and cannot be re-used anymore.
