Elon Musk is literally turning dirt into money.
The enigmatic American has outlined plans to use dirt excavated from tunnels to create bricks to build affordable housing.
The entrepreneur billionaire said that his tunnelling firm The Boring Company would create building materials using earth from tunnel boring. He wrote on Twitter: “The Boring Company will be using dirt from tunnel digging to create bricks for low cost housing.”
The firm confirmed on its website that it would research using the dirt to create bricks. It said: “The Boring Company is investigating technologies that will recycle the earth into useful bricks to be used to build structures.”
Musk first mentioned the scheme on Twitter in March saying, “Lifesize LEGO-like interlocking bricks made from tunnelling rock that you can use to create sculptures and buildings.
“Rated for California seismic loads, so super strong, but bored in the middle, like an aircraft wing spar, so not heavy.”
Musk, who is also chief executive of autonomous vehicle firm Tesla, established the tunnelling company in December 2016 to tackle congestion in Los Angeles after he got stuck in a traffic jam.
“Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging,” he posted on social media at the time.
Since then he has elaborated on his idea to create an underground network of traffic tunnels across the city, claiming cars would be able to travel through the tunnels at 130mph on electric skates.
