Railgun-Powered Ramjet Design

  1. Feb 16, 2017 #1
    Recently, I designed (in my head) a Hypervelocity Passenger Vehicle (just a cool name for really high speed transports). I immediately ran into engine design problems ( I like designing everything stand-alone), since regular jet engines can't get to Mach 8.8 without burning up into flames, and rocket engines are too polluting (and also I was obsessed with nuclear jet engines which doesn't use up any fuel whatsoever)
    So I spent roughly 2 minutes having a headache before coming up with an insane solution. A railgun-powered ramjet. (I named it Excel 1) However it would require laser-cooling systems to cool the Mach 8.8 air to a temperature where it becomes superconductive before being ejected out from the end by a railgun-style pulse engine design.

    My questions: At which temperature would air become superconductive?
    Is it possible to make a material which could sustain that temperature without shattering?
    Would it be possible?

    There is no temperature at which air becomes superconducting. In fact, as the different gases condense into separate liquids, it ceases being air.

    How about oxygen?
