What sets this railgun apart from the others is that it “uses magnetic fields, which means it’s a lot less messy, and you can dump tons of juice in and get the shell going damn fast.” Video after the break. Click here for first picture in gallery.

If you’ve got a little over 10 megajoules as with this demonstration model, you’re looking at 5,600 mph. When the system is completed, it’ll be firing shells with over six times that energy (well over 13,000 mph) using 64 megajoules of energy
