Hyperloop UPV
The Hyperloop UPV concept is a levitating rail-free pod design. Using magnetic repulsion and air cushioning for levitation is expensive and can produce unpredictable forces. The pod is equipped with a hybrid system of permanent magnets and electromagnet units, being able to control lift, so it can hover from the top of the tube. That way, the pod doesn't need so much electricity to be lifted by itself. Propulsion is obtained through expansion of the air with a nozzle, located at the rear of the pod, achieving speeds of up to 1000 km/h. The turbine recovers energy from the flow allowing a more efficient journey. This clean tube layout is said to cut costs in up to 30% of the whole Hyperloop project (about 180m USD) and the possibility to comfortably fit more passengers.
Hyperloop Transportation Technologies
By February 2015, the company had grown to nearly 200 people, and had announced that it would hold an initial public offering that year to raise . HTT also entered a formal agreement with GROW Holdings, the developer of Quay Valley, California, to construct a demonstration track beginning in 2016. By November, HTT had grown to just under 500 people. In August 2015, engineering design and construction firm AECOM began providing engineering services to HTT for the design of the full-scale Quay Valley prototype track. Also in August 2015, HTT announced partnerships with international engineering giant Aecom and Oerlikon, the world's oldest vacuum technology ."
