Actually, it's not hard to figure out if the energy need is practically met. It turns out it is, and rather easily.
A one ounce load at 1150 fps has a kinetic energy of approximately 1740 Joules.
A Lithium ion battery has an energy density of 460,000 Joules per Kg. This means a one ounce Li ion battery has in theory enough energy to fire about 8 shots.
In fact a size AA carbon zinc battery has the energy to fire one shot if we could somehow convert the electrical potential to kinetic energy.
The trick of course is to release ALL the energy over a few milliseconds. Can this be done with capacitors and coils?
I believe that it CAN be done, today, using current (pardon the pun) technology.
The switching power supply in your computer handles some large energy potentials and fields just to eliminate the need for a heavy iron transformer. It's not much of a stretch to projectile acceleration.
Someone will do it.
The next guy will hang two together and we will have an electromagnetic doublegun.
keith you should celebrate. How are they going to 'control' electric guns? Round up all the batteries, switches, and capacitors?
