the pods will travel in tubes about this size, and should be able to reach speeds of up to 670 miles per hour. 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 one being developed. underneath the streets of las vegas is another hyperloop tunnel, this one by the boring company — yes, the one owned by elon musk. his system will essentially be a underground motorway. old tv shows and movies may have led us to believe the future of transportation will include flying cars, but maybe the modern day version of that is actually a pod flying through a tube.
