The global engineer

I´ve been rolling around the world in the last couple of months. I´ve seen the Crown Jewels at the Tower of London and the Virgin of Guadalupe, the most visited shrine in all the Americas, on the edge of Mexico City. What connects these two mega tourist sites - each attracting millions of visitors a year - is the technology that trundles you past them. To see the Virgin or the Coronation Crown, you have to board a travelator and be transported at its pace - not your own - past the wonder of the cloak emblazoned with the Virgin´s image or the Koh-i-Noor diamond.
