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.<p>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?
