The Verge:

It only lasted about two seconds, but wow, what a sort of thrilling two seconds it was! Hyperloop One, the LA-based startup striving to realize Elon Musk’s pipe dream, conducted it’s first public open-air test in the Nevada desert Wednesday.

A crowd of wealthy investors, transportation experts, media, and even North Las Vegas Mayor John Jay Lee, watched as a roughly 10-foot long sled shot down a short train track and then crashed into a pile of sand.

See the video embedded below. I think this has real possibilities, not just a pipe dream.

Note that the concept is Elon Musk’s, but he open sourced it, encouraging others to actually build it. Hyperloop One is a startup whose goal is to build a Hyperloop designed to carry passengers from Los Angeles to San Francisco in about 35 minutes. Without killing them.
