"The Boring Company will be using dirt from tunnel digging to create bricks for low-cost housing," he wrote in a tweet about his nascent tunnelling enterprise.
Company spokesman Sam Teller confirmed the plans, saying the bricks will come from the "excavated muck." "There will be an insane amount of bricks," Teller wrote in an email.
How many affordable housing units that will create, though, is a different matter, says Juan Matute, a lecturer at the University of California, Los Angeles, and associate director of UCLA's Institute of Transportation Studies.
Musk’s tweet "assumes that housing costs are driven by construction materials, and particularly, construction materials that can be replaced by bricks," Matutue said. "That's not the case." At least in California, the only state where Boring Co. has started digging a tunnel, land and labour drive prices more than anything else.
