Even in a place known for its moonshots, Greg Henderson's Arx Pax might be the most ambitious startup you've never heard of in Silicon Valley.
An engineer at Arx Pax shows off the startup's second-generation hoverboard, the Hendo 2.0.
A skateboard deck might sit atop the Hendo 2.0's aluminum frame and four hover engines, but controlling the board is no easy feat.

Arx Pax also wants to use the technology underlying its hoverboard to lift buildings before an earthquake, control infectious disease and even pull satellites through space.
