Design: Hyperloop Italia & Zaha Hadid Architects
Zaha Hadid Architects (ZHA) has signed an agreement with Hyperloop Italia to jointly design its next phase of work.
Using passive magnetic levitation technology powered entirely by renewable energy, Hyperloop propels passenger and cargo capsules through low pressure tubes to minimize friction, requiring only a fraction of the energy required to power the modes. traditional public transport.
The combination of energy from renewable sources and regenerative braking systems allows Hyperloop’s infrastructure to produce more energy than it consumes. Air-conditioned passenger capsules travel in sealed tubes and are unaffected by external conditions.
