The city hall of four US cities, which, according to Mask, will be connected by ultra-high-speed tunnels, said that they had not heard anything about the permission issued to implement this grandiose project. Advisers to the municipalities of New York, Philadelphia and Washington, in an interview with the newspaper LA Times, were surprised to note that they did not know about the project being prepared before and did not participate in negotiations with Elon Musk. Baltimore Mayor Catherine Pugh issued a brief written press release in which she welcomed Musk’s undertakings, pointing out that Baltimore’s high-speed communication with the capital and New York City offers great promise and great potential. speculation about the start of work on the implementation of the Hyperloop project, since no one at the city hall had any discussions with Musk or his representatives, and there were no proposals to the mayor Bill de Blasio regarding this project. The representative of the mayor of Washington, Latoya Foster, also confirmed that she was the first to hear about this project. The press service of the mayor of Philadelphia emphasized that they did not have information about Musk receiving oral government permission to implement the project. The Philadelphia City Hall indicated the need for numerous administrative and technical permits to begin construction of Hyperloop. Earlier, Elon Musk announced that he received verbal permission from the US government to launch the Hyperloop project, an ultra-fast tunnel system that would reduce the time it takes to move between New York and Washington (250 km) up to 29 minutes. And as if anticipating the resistance of city administrations, Musk further emphasized that the work was at the very beginning, overcoming numerous administrative barriers and obtaining serious technical permits. The Hyperloop project was launched in 2012, when Musk proposed creating an underground tunnel network with the maximum discharge air for movement of ultra-high-speed cargo and passenger capsules at a speed of up to 1220 km / h. Friction in the tunnel will be minimized due to the air cushion and low air density. Hyperloop developers emphasized that such an idea would cost much less than a magnetic cushion rail. For example, Musk promises to tie Los Angeles and San Francisco (620 km) with Hyperloop for just $ 6 billion. For Russia, a pilot project is planned connecting Hunchun with the port of Zarubino.
