Christopher Merian, chief engineer, MIT Hyperloop, explains how the system works

Magnetic Hyperloop pod unveiled at MIT

A people-carrying pod designed to levitate and travel at extremely high speeds has been unveiled in Boston.

A 30-strong team from the Massachusetts Institute of Technology (MIT) is one of several groups and companies working on making the Hyperloop concept a reality.

The idea, first envisioned by Tesla chief executive Elon Musk, is to create a transport system that propels pods through airtight tubes.

The MIT team said its pod design paved the way for "a mode of transportation that could change how we think about travel".
