On Monday, a crowdsourced enterprise led by NASA and Boeing veterans called Hyperloop Transportation Technologies announced  it had licensed passive magnetic levitation technology to power its prototype system, which like other hyperloop templates, promises to shuttle humans and goods in a vacuum tube system at speeds up to 750 mph.

How fast is that? Zipping from Los Angeles to San Francisco would take 30 minutes as compared to a six-hour drive or an all-day train ride.

The announcement comes just two days before rival Hyperloop Technologies Inc. plans to showcase the evolution of its technology to investors and media in the desert north of Las Vegas. On its website, Hyperloop Technologies features photos and videos showing off large tubes that would house long pods for either people or cargo. Both HTI and HTT are based in Los Angeles.
