    HyperloopTT focuses on systems that moves people and goods safely, efficiently and sustainably; bringing airplane speeds to the ground by using passive levitation and electric linear propulsion in a low-pressure tube. This presentation discusses the complex power system challenges and collaboration with ETAP for conceptual design and detailed engineering of the 1st commercial prototype. The companies will then thereafter collaborate with ETAP and migrate the digital twin into operations to validate and improve the prototype design and extend to upcoming long-distance commercial & freight systems.
