A team of UC Irvine engineering students will go head to head this weekend with some 120 teams from around the world as it presents its sleek, frictionless version of a high-speed train that would travel from Los Angeles to San Francisco in a matter of minutes. UCI students, competing in the first-ever SpaceX Hyperloop Competition, have built a scale model of their HyperXite pod (pronounced Hyper Excite). The concept uses compressed air to levitate and glide the pod along a track.
