The firm plans to build a network of tunnels where vehicles are transported on electric skates to their destination, reducing traffic on the surface.
1,000 flamethrowers are being distributed today by The Boring Company at the first Not-A Flamethrower pickup party and buyers are ecstatic.
Elon Musk reportedly has a net worth over $20 billion.
The guns, which are more of a blowtorch than an actual flamethrower, are receiving some criticism for being unsafe. Shortly after the company sold out of the devices, Musk said it would have to make a change to the name of the flamethrower so that it could ship it to customers.
The billionaire posted a warning to Twitter Saturday: "Please use as directed to avoid unintentionally burning things down". "When the zombie apocalypse happens, you'll be glad you bought a flamethrower".More news: Anthony Bourdain's daughter, 11, in concert after his death

The hot ticket items also come with a 10-page manual including other sensible tips such as not pointing the Not-A-Flamethrower at your face, people, animals, or flammable objects, and not to touch the nozzle during or after use.
The devices - priced at $500 - generated $10 million in sales for the company during its pre-sales earlier this year.

In response to @SPPhotonic, Musk may have revealed an upcoming new TBC product when he tweeted, "Each flamethrower comes with a state-of-the-art The Boring Company brand fire extinguisher".
According to the company, the privately-funded tunnel would be able to transport cars at 150 miles per hour (240 kph) to help with LA's "soul-destroying" congestion.
