- Elon Musk is designing a new boring machine called Prufrock which may tunnel 10x faster than the machines used for his new car tunnel
- The new electric car tunnel is just 1.14 miles long and cost $10 to build including all internal infrastructure, lighting, communication and video, safety systems, ventilation and track, according to the company
- Musk estimates that electric cars could run at speeds of 150km through the proposed new tunnels.
- By comparison, the new Crossrail Elizabeth line is 73 miles in length with 42km of tunnels. Tunnelling progressed at 38m per day taking 3 years to complete using eight tunnel boring machines
- Crossrail tunnels are 6.2m in diameter vs the Musk car tunnel which is a more modest 3.6m in diameter, though this is clearly adequate for EV purposes. We suspect you will need a Tesla to use the tunnel.
