After two years of work, Jason (Larsplatton on youtube) has put together a fully functional coilgun. What's a coilgun you ask? Oh, just something that can shoot projectiles at high velocity via the use of magnetic velocity. Yeah, it's freaking awesome. This is one of those times when you look at a DIY project and say, "damn, wish I had the ability to build that too." Too bad it doesn't cool with schematics, but it does come with a video!
This coilgun is no toy. Using a large electromagnet, made from 10-gauge magnet wire, it delivers more kinetic energy than a .45 handgun, but less than an M16 rifle, according to Jason. If Jason was able to do this in his backyard with off-the-shelf components, you can just imagine what proper defense contractors should be able to do with a few billion dollars.
It's not 1.25KJ of kinetic energy, it's 1.25KJ of potential Ke at 100% efficiency. This thing got a relatively high 4% eff. rate, and has around the power of a 22, not a .45
