Tech entrepreneur Elon Musk said that The Boring Company will compete to fund, build and operate a high-speed loop that will connect O'Hare Airport to downtown Chicago
Musk recently started The Boring Company to build transport tunnels for the system,
which he says would be far faster than current high speed trains and use electromagnetic propulsion.
Chicago's mayor Rahm Emanuel asked respondents to present proposals to develop, design, equip, finance, operate and maintain an O'Hare Express operating system through a public-private agreement with Chicago.
When asked on Twitter to elaborate on his "high-speed loop" proposal
Musk tweeted say that a Loop is like a Hyperloop, but without drawing a vacuum inside the tube.
Musk is seeking to revolutionize transportation by sending passengers and cargo packed into pods through an intercity system of giant vacuum tubes known as the "hyperloop."
