The Hyperloop consists of a sealed capsule having a seating capacity of 28 passengers. The capsules are accelerated via a magnetic linear induction motor with stator affixed on the low pressure tube and rotors contained in each capsule.
For travel at high speeds, the greatest power requirement is normally to overcome air resistance. Air resistance increases with the square of speed, and thus the power requirement increases with the cube of speed. For example, to travel twice as fast a vehicle must overcome four times the aerodynamic resistance, and input eight times the power. Just as aircraft climb to high altitudes to travel through less dense air to achieve greater speed, Hyperloop encloses the capsules in a reduce pressure tube.
The Hyperloop has an operating pressure of 100 Pascal, which reduces the drag force of the air by 1,000 times and would be equivalent to flying above 150,000 feet altitude. The capsules are separated within the tube by approximately 37 km on average during operation. The capsules are supported via air bearings that operate using a compressed air reservoir and aerodynamic lift.
