The Brennan Self-Balancing Monorail

This is so cool: in the early 1900s, a mechanical engineer named Louis Brennan invented a self-balancing train that ran on a single track. This video demonstrates how the train worked using a clever system of gyroscopes.

This is the Brennan Monorail, a train from the early 1900s that seemed to defy the laws of physics. Not only did it keep itself perfectly balanced on a single rail, but it mysteriously leaned into corners without any driver input.

It’s kind of incredible how well Brennan’s system worked. It’s ingenious. (via messy nessy)
