This improbable-looking gyro-powered monorail appears to have been built by MORI Hiroshi. The monorail car balances on the track using a gyroscope flywheel, with a control system that can change its alignment to keep the car upright.
The concept was independently developed 100 years ago by Louis Brennan, August Scherl, and Piotr Schilovsky, each of whom built models large enough to transport humans! [via Make: Japan]

What an incredible build.
You should really add this older Make blog entry http://blog.makezine.com/archive/2008/10/electric_miniature_monora.html to this one, to inspire the masses.
Thanks for pointing that out, I missed it!
