    The first issue is definitely solvable, thats just a material science issue. The second one is also definitely possible, but depending on the payload it might be very difficult. Seems easier to just accelerate a tungsten sphere to mach 4 than to bother with a warhead.

    For the intense heat, thats a waste product. Get rid of it by not producing it in the first place. Which means your rails are now cryocooled superconductors.

    For the immense forces, i might need to look into railguns again. Afaik the only force that isnt being counteracted is the force on the projectile. I might be wrong at those power levels, while the net force should be zero the force on the arms could be opposite, ripping the railgun apart or crushing it. The solution i would think is coiling your rails around the barrel, now the rails effectively act as their own support with a minor bracing.

    For the record, i didnt put it together that he was referring specifically to the large models. I just knew i made a rail gun back in high school and its wasnt difficult, so the idea that the US govt cant copy my project struck me as absurd.

    Finally, im a hobby electrician with my passions lying more in technology and futurism, so i have looked into railguns in passing but I do not work for the military nor have i looked into the specifics of the large scale models, so corrections are more than welcome.

    Uh, what? Railguns are a tech as old as time, i highly doubt the US was the first to create one. I could throw a railgun together in about 30 minutes with the stuff i have laying around the house. They are INCREDIBLY simple, literally 1 moving part and no circutry whatsoever. Just hook your positive to one rail, negative to the other. Right hand rule tells you which direction your projectile will fire.

    Shoes. 3d printer filament. A laptop. Occasionally some shelf storage food. A thermal camera. Soldering iron and solder. Cast iron skillet. Pretty much everything that i would like to buy that isnt carried by my local grocery store and is also the only non gas station within 45 minutes of me. Thats assuming the weather is nice and i can actually drive my car the 45 minutes through the half that is pretty decent for roads, and the other half that will blow my tires and bottom out my car if i so much and blink or have a little bit of fog. Rain basically means i update my will before i go for a drive. The other 45 minutes back in fun too.

    Im still not sure why it was removed. Im not sure what the event was even for, but it looks like a showcasing of art projects? In which case, why remove it? It has connections to profane work, but is not of itself profane. Does having connections to profane works devalue the attatched piece? Does the piece not stand on its own merits?
