The R&D Tunnel, also called the Hawthorne test tunnel or Boring test tunnel, is a 1.14 miles (1.83 km) tunnel in Hawthorne, California, for testing hyperloop and "loop-based transportation". [3] It was completed by The Boring Company in late 2018.
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. Tunnels are excavated through hard rock, wet or dry soil, or sand, each of which requires specialized technology. Tunnel boring machines are an alternative to drilling and blasting (D&B) methods and "hand mining".
Elon Musk speaking at the inauguration of the test tunnel in Hawthorne, California, December 2018. In early 2018, the Boring Company was spun out from SpaceX and into a separate corporate entity. [13] Somewhat less than 10% of equity was given to early employees, and over 90% to Elon Musk. Early employees came from a variety of different ...

Microtunneling or microtunnelling is a tunnel construction technique used to construct utility tunnels from approximately 0.5–4 m (1 ft 8 in – 13 ft 1 in) in diameter. Because of their small diameter, it is not possible to have an operator driving the tunneling machine, so they have to be remotely operated. [1] Micro tunnel boring
Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes
