Aerotropolis I love my job – I always have done. Now in retirement I can look back at how aviation and our way of living have changed. I am one of the few generations that experienced such a dramatic transformation during my working life. Back in 2016 there was always an element of guilt with my job. A short-haul flight from Zürich to Cyprus emitted one ton of C02. At that time the emissions in Switzerland where 6.06t per Capita. The worlds aviation industry contributed to two per cent of global emissions. The airplanes we used burnt Kerosene, a fossil fuel a resource that our population has since used up completely. The way we lived was also different, people lived very individual lives scattered about the place and spent a lot of time getting from one place to another. This travelling around on the ground also caused a lot of emissions. I myself lived in a village 45 minutes away from the airport and used my car to get to the nearest train station from where I took a train to the airport. Today, living in the airport city with the underground Hyperloop is much more efficient. I was lucky to watch this city of synergies be built from the beginning. The original airport had reached maximum capacity and had no room to expand as well as being far away from the people that needed to reach it. After years of discussion within the government it was decided that the new aerotroplis should be built. I’m not going to lie the beginning was a struggle. In 2020 we were living on a building site and still flying with kerosene….  Hyperloop is a proposed mode of passenger and freight transportation that propels a pod-like vehicle through a near-vacuum tube at airline speeds. The pods accelerate to cruising speed gradually using a linear electric motor and glide above their track using passive magnetic levitation or air bearings. The tubes can go above ground on columns or underground, eliminating the dangers of grade crossings. It is hoped that the system will be highly energy-efficient, quiet and autonomous.
