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.
Elizabeth River Tunnels Project
In 2006, the Hampton Roads Metropolitan Planning Organization (MPO) (formerly a subcommittee of the HRPDC, now known as the Transportation Planning Organization) concluded that new tolls could help secure funding for transportation projects that were removed from the 2026 RTP, including the Midtown Tunnel and MLK Extension. This would include tolling the parallel Downtown Tunnel to create a congestion-management plan to prevent the diversion of potential Midtown Tunnel traffic to a competing free facility. Both tunnels were initially tolled (25 cents, both ways) to pay off their construction bonds; both were made free in the late 1980s after the opening of the second (eastbound) Downtown Tunnel. Options included adding a 58-cent toll to the Midtown Tunnel (and a 19-cent toll to the MLK Extension), which could raise $427 million for the project; or adding a $2.05 peak/$1.50 off-peak toll for the Midtown, and a $2.20 peak/$1.60 off-peak for the Downtown Tunnel, which could raise nearly $4.8 billion. Based on this study, the MPO added the projects to the regions 2030 RTP, now estimated to cost around $779 million— if the Virginia General Assembly approved the new tolls and several tax increases.
