>but don't railguns launch projectiles?
Yes, which is exactly why they are more efficient than tesla coils. You pack all the energy into a lump of metal and make it go really really fast, and that lump of metal is only constrained by friction and gravity and none of those have inverse square roots. By converting the energy from one form into another form that is easier to transport from one place to another, you have made it more efficient.
>What you think they are doing at HAARP?
Not fucking blowing up tanks with lightning bolts.
