This is a really interesting topic, but how much battery can one dude carry on him for a welder? do man-portable electric welders even exist?
Also, what would be ther best filler material to put between the electrode plates? best metal for the plates? thickness?
How much energy does it take to melt a single bullet?
what happens if the melted bullet connects the two plates and they melt together?
I think this technology's best application will be a railgun tank. Railguns in the field are juuuust starting to become feasible, but we'll see them as ship guns and stationary artillery first, then an SPG, then perhaps a tank(it'll probably be more like a infantry fire support vehicle, taking the role of the stryker dragoon). A railgun tank would be kinda like the abrams but without most of the armor, same two turbines running generators, a huge capacitor bank, and lots of fuel. This thing will drink gas even faster than the abrams, because gas is also your gunpowder. However, you get a railgun; you can shoot the same projectile much faster and further than before. This kind of standoff range can be decisive. Another thing to consider: torque. Electric engines are bi-directional and very torque-y, making them very suitable for tanks, which need to be able to forward/reverse a few feet as fast as possible. This electric armor is just icing on the cake.
railgun tank vs conventional tank:
>greatly reduces logistical needs because:
>is a very efficient generator for the unit
>ammo is smaller
>no explosive ammo so cheap ammo and no shipping hazards
>only need diesel and ammo
<but lots of it. which we already can and usually do supply.
>can shoot further than conventional guns
>extremely high velocity rounds
>fast reverse acceleration cus omnidirectional motor
<guzzles diesel like a fucking jet hovering when firing at full power
<no explosive ammo
<you must now train tankers how to deal with extremely high voltage
<tankers will have to manage their charge level in battle and may not be ready to fire when needed
<high-end capacitors are explosive
i have a feeling that some explosives can handle being accelerated faster than a standard cannon but not quite at railgun speeds, so a 1/2 of 2/3s power railgun might be able to fire a HEAT shell with reduced range. But thats assuming that the projectile heating up is accounted for too. It could probably fire conventional shells, but at conventional (or moderately better) velocities.
