The premise of what hes doing is "lets do it faster and cheaper"... If you could improve the boring process 10x, maybe people would look at digging tunnels in a completely new light!!!
For example, the real problem with rail is getting right-of-way. With a cheap boring machine - your plans wouldn't be as difficult. As Musk put it, you got to think in 3D....
- AlexandrB 10y agoActually you should think in 4D. In the future all those tunnels require maintenance that is much more complex and expensive than maintenance for surface roads. If the US is not able to keep its roads in good condition (and in many places it's not), how is building more expensive roads underground going to solve the problem long term?
- JoeAltmaier 10y agoRoads need maintenance almost exclusively because of the weather - sun and rain, heat and cold. Underground, none of those things. We have tunnels today that are a century old with only minimal maintenance, right?
- jcranmer 10y agoWe have tunnels that are a century old which are in danger of complete failure. Underground structures tends to exacerbate issues with water intrusion and drainage, not to mention persistent problems with air quality (air can only diffuse effectively in 1 dimension, not 3).
