The total trip time is approximately half an hour, with capsules 
    departing as often as every 30 seconds from each terminal and carrying 28
    people each. This gives a total of 7.4 million people each way that can be 
    transported each year on Hyperloop. The total cost of Hyperloop in this 
    analysis is under $6 billion USD. Amortizing this capital cost over 20 years and 
    adding daily operational costs gives a total of about $20 USD (in current year 
    dollars) plus operating costs per one-way ticket on the passenger Hyperloop.

    For aerodynamic efficiency, the velocity of a capsule in the Hyperloop is 
    - typically: 300 mph (480 kph) where local geography necessitates a tube bend radii 
      < 1.0 mile (1.6 km)
    - 760 mph (1,220 kph) where local geography allows a tube bend > 3.0
    miles (4.8 km) or where local geography permits a straight tube.
