Hustro — Hustro - MainSite
Nevomo — Nevomo develops the next generation of High-Speed Railways (HSR), based on magnetic levitation, linear motor and autonomous control systems, which can be subsequently transformed into a vacuum version. It is the only company globally working on technology enabling a gradual implementation of Hyperloop-inspired solutions as an upgrade for therailway industry. The company has developed a unique, patent-pending magrail technology, which allows modernizing existing conventional railway lines to a standard of passive magnetic railways, reaching speed of 300 kph (186 mph) on normal lines and 415 kph (258 mph) on HSR lines. The magrail system allows keeping the functionality of conventional railways on a modernized line (railway operators can depreciate their existing rolling stock).Magrail can be subsequently transformed into a vacuum system – hyperrail, reaching speed of 600 kph (373 mph) on normal lines and 1000 kph (621 mph) on HSR lines.The third generation is hyperloop – vacuum magnetic railways built within new transportation corridors for top speed of 1200 kph (746 mph), using subsystems tested in the first two generations.Capex for retrofitting railway infrastructure to a magrail standard are estimated to ca. EUR 6-8 million per km, which is comparable to the cost of building a new highway and up to 60-70% lower than the average cost of building a new HSR line in the EU. Energy costs will be lower by ca. 13% for the speed of 300 kph (186 mph) compared to HSR, whole for the speed of 415 kph (258 mph) magrail needs the same amount of energy than HSR currently for 300 kph (186 mph). The maintenance costs will be ca. 25% lower than for HSR, due to elimination of friction of mechanical elements at high speeds.The company was founded in 2017 and until mid-2019 it submitted 8 patent applications. In the first half of 2019 it secured an EUR 3.8 million grant in Poland and raised EUR 334 thousands during the first Polish equity crowdfunding campaign on a UK-based platform Seedrs. Currently a Proof of Concept (PoC) is almost completed (ca. 50 m. long test track, which will be demonstrated in Q4.2019)., while at the turn of 2020 and 2021 a demonstration of the first full-scale prototype is planned.Corporate partners include TME Transfer Multisort Electronics and Microsoft.
