The hull of a 1,200 km/h bullet train is 10 times harder than steel.

Billionaire Elon Musk's Hyperloop technology company plans to build a high-speed train hull from vibranium, a super-light smart metal that is 10 times stronger than steel.

The Hyperloop concept was first proposed by Elon Musk, founder of the aerospace company SpaceX and the car company Tesla, in 2013. This type of vehicle would replace current ground transportation methods in a completely new way. Hyperloop trains travel in tubes connecting major population centers at speeds of 1,223 km/h.

According to Futurism, the Hyperloop hull will be made of vibranium, named after the metal that made Captain America's shield in the superhero movie Captain America. This is a smart material woven from carbon fiber, 10 times stronger than steel but 5 times lighter.

Vibranium also incorporates thousands of wireless sensors that transmit diagnostic information, relaying real-time data on temperature, damage, and structural integrity. Vibranium will continuously transmit information to the processing center, allowing for timely maintenance in the event of a Hyperloop malfunction.
