Will The Hyperloop Arise—In Slovakia?

The Slovak Republic will "explore" building a superfast vac-train from Bratislava to Vienna and Budapest

A train faster than any other on earth is being explored by the government of the Slovak Republic and Hyperloop Transportation Technologies (HTT), a Southern California startup.

“Explore” is the restrained word used in the joint press release, which set no deadlines and mentioned no sum of money. Even so, this represents the first solid evidence that anyone might build a large-scale version of the Hyperloop, Elon Musk’s 2013 concept for shooting passenger-carrying pods through partially evacuated tubes at just-barely subsonic speeds.

HTT is building a small, 8-kilometer (5 mile) test track along a highway that runs between Los Angeles and San Francisco. 

The release speculated on several possible routes originating in the capital city of Bratislava, in western Slovakia. One might run the 400 km (250 mile) to Košice, in the eastern part of the country. HTT says the trip would take only 25 minutes at full speed—a bit more than 1,200 km per hour (760 mph). A 70-km westward route to Vienna, Austria, would take 8 minutes. 

“Hyperloop in Europe would cut distances substantially and network cities in unprecedented ways,” said Vazil Hudak, Minister of Economy of the Slovak Republic, in the statement. “A transportation system of this kind would redefine the concept of commuting and boost cross-border cooperation in Europe.”

Travel times depends not only on the top speed of the system but also on the g-forces that passengers can comfortably withstand. The stress comes not only at the beginning and end of a trip but also at every bend along the route. HTT puts the maximum force at 1 g, arguing that “the experience is similar to a performance car.”

Editor’s note: this article has been corrected: Bratislava is indeed west of Košice.

We Need More Than Just Electric Vehicles

To decarbonize road transport we need to complement EVs with bikes, rail, city planning, and alternative energy

EVs have finally come of age. The total cost of purchasing and driving one—the cost of ownership—has fallen nearly to parity with a typical gasoline-fueled car. Scientists and engineers have extended the range of EVs by cramming ever more energy into their batteries, and vehicle-charging networks have expanded in many countries. In the United States, for example, there are more than 49,000 public charging stations, and it is now possible to drive an EV from New York to California using public charging networks.

With all this, consumers and policymakers alike are hopeful that society will soon greatly reduce its carbon emissions by replacing today’s cars with electric vehicles. Indeed, adopting electric vehicles will go a long way in helping to improve environmental outcomes. But EVs come with important weaknesses, and so people shouldn’t count on them alone to do the job, even for the transportation sector.
