Elon Musk announced that the Boring Company will sell LEGO-like interlocking bricks made from rock that his tunneling machines excavate from the earth. Musk stated these bricks will be sold in “kits” and will be rated to withstand California’s earthquakes. 

The date of availability or cost of this latest product is unknown. While his company has only started digging shorter tunnels there is not enough upturned rock to begin making these bricks yet.
