Modern life rests on inventions so ordinary that we barely notice them… until they start to fail.

This week on The Capitalist, Marc Sidwell speaks to the writer and CapX columnist Jonn Elledge. His new book ‘31 Inventions That Built Our World’, surveys the technologies – from sewers to lifts – that make urban life possible. They discuss what it takes to keep a modern city running, and whether we are losing our nerve when it comes to building twenty-first century infrastructure.

They also talk about the PT Barnum stunt that convinced the public it was safe to ride in a lift, why nowhere on Earth held more than about a million people until the 1800s, the speed limit that stood in the way of commuting and why market pricing – not more regulation – is the answer to the mess we’ve made of urban space.
