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)

Happy hour

Just in time for Friday afternoon, a cedar beer cozy and a collection of beer sweaters. Wash it down with some beer soap.
