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.
Martin Luther King Jr. Expressway (Portsmouth)
Originally, the MLK Freeway was to be tolled $1.00 for non-tunnel users and $.50 for users who also travel through the tunnel. However, Virginia Governor Terry McAuliffe announced on July 10, 2015, that $78 million of construction money originally designated for the now defunct Route 460 project (which was another PPP approved by his predecessor, Bob McDonnell) would be reallocated to buy out the MLK Freeway tolls for the remainder of the concession period.
