Going underground: cities of the future

I love the outdoors, rain or shine. The trees and their winged denizens chirping away makes you feel one with nature. Looking up at the night sky at the march of the Zodiac with the occsional shooting star is very satisfying.
With the advancement of technology we now have the capability going underground. I for one find this abhorrent.

Now comes a suggestion for another underground network, one for people and cyclists. Design firm Gensler has proposed the creation of subterranean walkways beneath the Capital, funded by the creation of underground shops alongside them and powered by energy harvested from users’ footsteps using Pavegen technology.
Later this month, a conference at the Institution of Civil Engineers will explore what the UK’s engineering community has learned from its last 10 years of designing and building new tunnels, but also the potential for putting this expertise to use in the future.
