I was kind of shocked to see their illustration was tunnelling under a road. It may have been a misapprehension but I thought they were aiming much longer tunnels. Obviously the fact they think they can deploy much quicker than traditional TBMs means that has a huge impact on total time. Also, if you tell me you can sell cornflakes cheaper than kelloggs, I don't expect you to deliver me 60% less conflakes. So why is the diameter redution being counted as a way to reduce cost?

Boring under roads is a big market. Suppose you need to upgrade a water or sewer line but the main runs on the other side of a road. If it's a very minor road made of asphalt, cut and cover is an option. If it's a significant road paved with concrete, boring is usually the only option and it's expensive. All kinds of services need to cross roads and the need is ubiquitous. The market is somewhat like the power wall for battery technology.
