Thyssen Krupp Elevators for the future

Thyssenkrupp: test track for fast-paced elevators  Cabins race through the shafts at 64 km / h  Engineers let the test tower swing on purpose  The elevator without ropes can also move sideways
The Essen-based company Thyssenkrupp has built a spectacular test track for fast elevators in the Swabian town of Rottweil. The tower is 246 meters high and looks like a gigantic chimney. But there is no smoke in the tower, but top technology.
Turmchef Thomas Ehrl from Westphalia chases together with his team prototypes for new elevators through twelve shafts. The elevators will be as fast as 65 km / h; Sensors measure acceleration, braking behavior and vibration. At the top and in the center of the tower is a 240-ton weight of steel cables. The vibration damper is a huge pendulum. There is such a thing in every modern uphome to dampen the normal wavering. In Rottweil, on the other hand, the engineers deliberately put their tower on the move with this technique. "We can even simulate the vibrations of skyscrapers that do not yet exist," says Thomas Ehrl. "This is how we can construct the appropriate elevators for each building."
The test tower costs 40 million euros. It is already a landmark for the region. And also for Thyssenkrupp.
Elevator of the future
In the test tower, the engineers are giving the finishing touches to a completely new system. In July they want to present the "Multi": an elevator without ropes, which not only runs upwards but also sideways, with many cabins in a single shaft. In this process, the technology of the Transrapid magnetic levitation railway failed miserably years ago. Also the cabins of the "Multi" float on a magnetic field. The developer's promise: no more waiting, every 15 seconds a cabin comes. Thus, few elevator shafts are needed and the construction of high-rise buildings becomes cheaper. Thomas Ehrl and his colleagues have long since joined the next project. "We can think about the elevator technology of the coming 10, 15, 20 years, these are the periods that concern us."

My humble question: Would they use any magnets but permanent magnets? And by the way, visit Rottweil, one of the nice german cities from medival times if You should happen to travel to Germany.
