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
TransPod vehicles are being designed to travel at over 1,000 km/h between cities using fully electric propulsion and zero need for fossil fuels. The TransPod tube system is distinct from the hyperloop concept proposed by Elon Musk's Hyperloop Alpha white paper. The TransPod system uses moving electromagnetic fields to propel the vehicles with stable levitation off the bottom surface, rather than compressed air. TransPod is stated to contain further developments beyond hyperloop. To achieve fossil-fuel-free propulsion, TransPod "pods" take advantage of electrically-driven linear induction motor technology, with active real-time control and sense-space systems. The cargo transport TransPod pods will be able to carry payloads of 10–15 tons and have compatibility with wooden pallets, as well as various unit load devices such as LD3 containers, and AAA containers.
