Hyperloop Passenger Capsule
$ I* |: k/ `$ F/ `5 }1. Tube air is compressed with a compression ratio of 20:1 via an axial compressor.

a. The air travels via a narrow tube near bottom of the capsule to the tail. , r4 Y; j" f5 k- _% U4 S
b. A nozzle at the tail expands the flow generating thrust to mitigate some of the small amounts of aerodynamic and bearing drag. 4 r; d* `5 M9 Z' m
3. Up to 0.44 lb/s (0.2 kg/s) of air is cooled and compressed an additional 5.2:1 for the passenger version with additional cooling afterward.
7 M x; D1 s2 P9 k& l+ H9 N: \% ha. This air is stored in onboard composite overwrap pressure vessels.
4 ^/ B# Z8 |5 G V a% Hb. The stored air is eventually consumed by the air bearings to maintain distance between the capsule and tube walls. 7 u! H j5 l: B6 g2 B9 d' G
4. An onboard water tank is used for cooling of the air. $ ~& D8 C, Z1 H. T( }8 B* Z y
a. Water is pumped at 0.30 lb/s (0.14 kg/s) through two intercoolers (639 lb or 290 kg total mass of coolant). R' J: g+ D2 }* s
b. The steam is stored onboard until reaching the station.

5. The compressor is powered by a 436 hp (325 kW) onboard electric motor:
