1 cost of tunnelling could be significantly reduced by halving tunnel diameters - ok so you can put one car thro the tunnel certainly not mass transit
2 doubling the power of tunnel boring machines - for what?, the limiting factor is cutterhead revs, and muck removal - increase rev speed and you'd bake the head in the ground like a gypsy's hedgehog supper
3 using a continuous excavation and lining process - we already do this - Channel Tunnel c. 1989
Great stuff but nothing new about building at the same time as mucking, we did that on the UK side of the Channel Tunnel in 89/90.

Why do journalists often default to women in engineering when reporting on diversity? The Chartered Management Institute's approach on diversity is as follows:
"The concept of diversity encompasses any sort of difference between individuals. These could be differences in ethnic origin, age, disability, gender, gender identity, sexual orientation, family status, religion, education, social class and even personality or attitudes. The management of diversity involves developing and
implementing inclusive strategies through which a network of varied individuals are integrated into a dynamic workforce."
