Quay Valley, California
In March 2015, Dirk Ahlborn, the CEO of Hyperloop Transportation Technologies (HTT) in El Segundo, California announced a plan to build a hyperloop test system at the Quay Valley site. Ahlborn indicated that construction could begin in 2016 to be completed in 2017 with the first rides to begin in 2018 if his company can raise $100 million in funding. The company has said that this track will be a fully working and operational creation of the hyperloop, but that running speed will be reduced on the shortened track from Hyperloop's full potential. It is not decided whether a 5-mile loop or straight section will be constructed, and it may cross the Interstate bisecting the site. Ahlborn said that speeds up to may be possible. Quay Hays expects to break ground on the new community in 2016, including a working version of the Hyperloop, estimated to cost $100–150 million.
Hyperloop UPV
The concept developed by Hyperloop UPV is distinguished by the use of magnetic levitation based on attraction to the top of the tube thanks to its levitation units located at the top of the pod, instead of air-bearing systems based on repulsion to a rail located at the bottom of the tube. Moreover, its aerodynamic design allows to a compensation of inertial forces that permit a higher radius of curvature, a lower cost for the air-evacuation and up to a 30% savings in infrastructure, with respect to other proposals. This revolutionary concept of Hyperloop is powered by detachable batteries and is propelled through compression and expansion of the air with a nozzle. A turbine recovers energy from the flow allowing a more efficient journey. With all these features it is pretended to reach velocities up to 1200 kph, in a totally efficient manner, due to the use of renewable energies and prescinding from the use of fossil fuels.
