Elon Musk is not a man to miss an opportunity, and he's just discovered a profitable way to deal with all the waste rock has piling up: turn it into Lego!

The growing pile of rock is what's leftover when the company's excavators form the tunnels that will eventually transport vehicles at 125 mph using underground sleds. Rather than paying to have disposed of, Musk will create "lifesize Lego-like interlocking bricks" which can then be used to create sculptures or buildings.

In Musk's tweet announcing the new Boring Company product, he points out the rock is "rated for seismic loads" meaning it is very strong. However, it's hollow in the middle and therefore not very heavy.


In a later tweet, Musk also confirms kits will be offered with the first being for ancient . It will include interlocking bricks that allow you to build pyramids, a Sphinx, the Temple of Horus and some other well-known landmarks. Unfortunately, pricing has yet to be confirmed, but I imagine shipping costs will be quite high and international delivery rates extortionate.

Lego-like bricks is the third side-product The Boring Company is going to offer. We've already had branded hats and a flamethrower. We have to assume that the brick kits will be flamethrower proof, and someone is sure to test that and post the evidence on YouTube.

Once SpaceX makes it to Mars and sets up a transportation link back to Earth, I think we should expect the brick kit range to expand with some very limited editions. Mars does have a lot of rock, after all.
