> For all its technological whizzyness, the system has downsides. Cost is one. Mr Redi reckons each raising of the barrier costs about €150,000 (other estimates are higher).
Great article but I'm really curious about this number. If the alternative to raising the barrier is "the entire city floods" then that... seems like a pretty good trade? Also, nobody talks about the cost of raising and lowering a drawbridge. The whole point of it is to be raised or lowered, just like the barrier.
