They work, but even the military are struggling to make it efficient.

The sheer amount of power you need in the first place is one problem (and batteries remain the thing which is holding-up many new technologies at the moment) but the real bugger is the size and weight of the components.

It takes a good couple of kilos in parts to make something that has the power of an air-pistol.

Give us carbon nano-tube batteries and hyper-capacitors, room temperature superconductors etc, and we'll see this become practical. Until then, it remains sci-fi waiting to happen. It's why the Large Hadron Collider is large.
