What is HYPERLOOP?Hyperloop is a new mode of transport -Both fast and inexpensive for people and goods. -Open design concept-Consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. Elevated system of transportation through a tube between citiesIdea proposed by Elon Musk, founder of Tesla and SpaceXSimulations and model-building in progress

Allows the capsule to traverse the relatively narrow tube without choking flow that travels between the capsule and the tube walls (resulting in a build-up of air mass in front of the capsule and increasing the drag) by compressing air that is bypassed through the capsule. Thus overcoming Kantrovitz limit.

Supplies air to air bearings that support the weight of the capsule throughout the journey.COMPRESSORS15

SUSPENSIONAir bearing suspension. Offers stability and extremely low drag at a feasible cost by exploiting the ambient atmosphere in the tube.16

ON BOARD POWER5,500 lb (2,500 kg) of batteries to power the onboard compressor and capsule systems in addition to the compressor motor and coolant.Advanced linear motor system is being developed to accelerate the capsule above1,220 kph)at a maximum of 1g for comfort. The moving motor element will be located on the vehicle for weight savings and power requirements whileThe tube will incorporate the stationary motor element (stator) which powers the vehicle.PROPULSION17

TUBE18

TUBEHYPERLOOP consists of a partially evacuated cylindrical tube that connects the Los Angeles and San Francisco stations in a closed loop System .The tube is specifically sized for optimal air flow around the capsule improving performance and energy consumption at the expected travel speed. The expected pressure inside the tube will be maintained around 0.015psi (100 Pa, 0.75 torr), which is about 1/6 the pressure on Mars.19

ROUTEROUTE OPTIMISATIONHyperloop was initially designed to travel between Los Angeles and San Francisco in approximately 35 minutes To avoid bend radii that would lead to uncomfortable passenger inertial accelerations and hence limit velocity. Optimized by Deviating from the current highway system, Earth removal, Constructing pylons to achieve elevation change or Tunneling.20
