Boring Company, another one of Elon Musk's ventures, is planning to build a high-speed transportation link to the Chicago's airport that will be powered by batteries and gets people to and from the airport three or four times faster (at a speed of up to 150 miles per hour). Chicago's announcement of their decision to use Musk's company came just recently.

"We're really excited to work with the Mayor and the City to bring this new high-speed public transportation system to Chicago!" the Boring Company tweeted yesterday.

The trip from O'Hare International Airport to downtown Chicago should only take around 12 minutes after the transportation link has been completed.

Chicago Mayor Rahm Emanuel said that "We're taking a bet on a guy who doesn't like to fail â€" and his resources. There are a bunch of Teslas on the road. He put SpaceX together. He's proven something."

The cost and timeline of the project is not known yet, but the project will be 100% privately funded as Chicago wants Boring Company to do everything - design, build, finance, operate, and maintain the system.
