but more importantly than that, it's going to house all of the tech that makes this hyperloop system work. now that's important because if something breaks or goes wrong, all they have to do is remove the pod and fix it somewhere else, instead of going into the tube and potentially disrupting a lot of travel. one of the key components of hyperloop travel is the ability to go really, really fast. so they designed a way for the pods to levitate using opposing magnets, which in theory will help it go as fast as an aeroplane. the pods will travel in tubes about this size, and should be able to reach speeds of up to 670mph. that is fast enough to get you from london to paris in under half an hour. the system of tubes can be built on land, over water or underground — and maybe, just maybe one day, across oceans. but building an entirely new infrastructure across a city or country will take a lot of work, and a lot of money. but virgin's hyperloop system isn't the only
