This one is one of my little nerd obsessions, ever since Cobra Commander had one built onto Megatron's new Generation 2 body in GI Joe (What? I said it was a nerd thing. Don't @ me). The Rail Gun.
They're somewhere between a cool idea, and a terrifying one, as they are being developed in real life, and hey, apparently we didn't have enough ways to kill each other.
If we are going to kill each other, there is some very cool technology behind this particular method. It's a way of turning basically anything that can be magnetised into a bullet, or even a mini missile. It would also be a pretty quiet weapon, as the electromagnets would substitute, or even improve on, gunpowder.
The design I ended up devising for the Railgun rifle needed basically 3 elements - a supply of objects that could be used as ammunition (I was thinking small ball bearings, but in theory it could be anything that can be affected by electromagnetism); 2 rails to generate the electromagnetic field that accelerates the ammunition, and; a Power source to generate electromagnetic field.
As you can see, I put those elements together in a simple protective shell (no reason to have exposed circuitry or machinery. I even labelled the design! Just being helpful. You're welcome.
And of course, I have Rob's 3D model, which is a really good one.
So, that's this rifle (so far). Subscribe to the newsletter, and follow me on Tumblr, Facebook and/orTwitter so you don't miss the next update!
