Musk, who also leads electric-car maker Tesla Inc and rocket company SpaceX, has been seeking to revolutionize transportation by sending passengers packed into pods through an intercity system of giant, underground vacuum tubes known as the hyperloop.
In the past, Musk has sold Boring Co's hats and flamethrowers to raise funds.
The company has completed its project Test Tunnel, located in Hawthorne, California, and other ongoing projects include the Chicago Express Loop and the Las Vegas Convention Center Loop. (http://bit.ly/2NenvXU)
