Alphabet CEO planned Hyperloop-like system for bikes: Report
Google parent Alphabet's CEO Larry Page was reportedly working on a Hyperloop-like system code-named Heliox that would propel bicyclists in a tube system to commute faster. It consisted of a plastic tube, snaked around a circular track, hundreds of feet in the air. It was designed to propel bicyclists at rapid speeds by pumping helium and oxygen into the tube.
