  8. 8. 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 cities • Idea proposed by Elon Musk, founder of Tesla and SpaceX • Simulations and model-building in progress 8

  10. 10. Technology • Pods float on cushion of air through low-pressure tube • Magnetic linear accelerators to accelerate pods • Solar power to propel pods • Simulation technology shows feasibility (Ansys software) 10

  15. 15. •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. 15
  16. 16. •Air bearing suspension. •Offers stability and extremely low drag at a feasible cost by exploiting the ambient atmosphere in the tube. 16
  17. 17. •5,500 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 while •The tube will incorporate the stationary motor element (stator) which powers the vehicle. 17

  19. 19. HYPERLOOP 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
  20. 20. Hyperloop 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
  21. 21. Cost • Estimated cost of the Hyperloop vs. the California rail project Estimated Cost Average Speed Cost of One-way Ticket (LA to SF) Type of Cargo Hyperloop $6-$7.5 billion 598 mph $20 Passenger s and vehicles California rail project $68.4 billion 164 mph $105 Passenger s 21
  22. 22. Future plans • Marco Villa and Patricia Galloway guide the progress of the project • Marco Villa- former director of mission operations at SpaceX • Patricia Galloway- former president of the American Society of Civil Engineers • JumpStartFund plans to help finance the Hyperloop through crowdsourcing 22
  23. 23. Benefits and Implications • Drastically reduced commuting time • Transition from living in major cities to suburbs • Increased speed of business transactions • Reduced need for telecommuting 23
  24. 24. Benefits and Implications • Green technologies involved in Hyperloop powering • Less cars on the road • Less energy requirements • Less air pollution • Reduced emissions of greenhouse gases 24

  26. 26. Issueswith Hyperloop • Costs are underestimated • Technology not ready • Lack of political support *See Elon Musk’s argument for Hyperloop here. 26
  27. 27. Costs Underestimated • Only cost of materials • No account for unforeseen engineering/technological problems • Not calculated from downtown to downtown • More expensive/person 27
  28. 28. Lack of Political Support • Musk not willing to lead • No politicians • Knowledge not wide-spread • Lack of public support 28
  29. 29. Technology not ready • No prototypes • Engineering/physics • Not tested 29
