The ultra-high-speed mass transit brainchild of Tesla boss Elon Musk has created a hotbed of competitive rivalry with major stakeholders swapping criticisms at the St Petersburg International Economic Forum in Russia.
Musk's Hyperloop idea aims to revolutionize transport and let people travel at just under the speed of sound. It works by transporting a number of passengers in capsules that would be propelled by magnets at a speed of 750 mph – and could take you from Los Angeles to San Francisco in 30 minutes.
Several start-ups are working on the concept of Hyperloop, including Hyperloop One and Hyperloop Transportation Technologies (HTT), and are at varying stages of development. The race to be the ultimate leader in the space has spurred a heated debate between the firms.
"We are actually engineering and building and using steel, not powerpoints. And we hit 100 miles per hour in one second and we'll hit 700 mph by the end of the year. Full scale, full pod, we'll be able to do cargo, people. So you'll use Uber within the cities for transportation and then between the cities you would use Hyperloop," Shervin Pishevar, chairman and co-founder at Hyperloop One, told CNBC on the outskirts of the Russian conference on Friday.
"Hyperloop One is the only one company that has the product. No-one else does, they just have talk ... we've raised the capital, we've built the company, 170 full-time employees. They (the competition) have just slides," he added.
