Technology
The main power source is a hydrogen fuel cell. In stand-by configuration, the vehicles front wheels deploy to the ground like a jet plane landing gear to increase longitudinal stability.
A Rider-Friendly Vehicle
[...]With a riding position similar to a motorcycle, the EMBRIO uses a complex series of sensors and gyroscopes to balance one or more human passengers on a single wheel. Technology will be used to harness the laws of physics, with the gyroscopes and sensors, a high-performance braking system, active suspension, night vision and robotic assistance. A digitally encoded learning key will start the engine. To move forward, the rider activates a trigger on the left handlebar. The landing gear retracts when the speed reaches 20 km/h. To turn, the rider leans in the desired direction. The brake is activated by a trigger on the right handlebar. When the speed drops to 20 km/h again, the landing gear redeploys automatically. Even without the landing gear, the EMBRIO would be stable when motionless because of the gyroscope.
