From Forbes:
The Embrio concept also uses one less wheel than the Segway and will attract, Bombardier hopes, a younger demographic. The vehicle is designed as a guess at what transportation in the year 2025 might look like.
It is a fascinating idea because it combines the simplicity and alternative-fuel technology of forward-thinking commuting vehicles with the excitement of "recreational" products like ATVs. Indeed, the Embrio could attract people who drive a more fun sort of vehicle, what with its motorcycle-derived styling cues and, like an ATV, the fact that you have to lean in order to turn.
The Embrio is powered by a hydrogen fuel cell, a technology that creates power by mixing hydrogen and oxygen, ideally resulting in water as the only exhaust.
