UPDATE: Treehugger scans a lot of sites and reads a lot of papers. This item was in Forbes Magazine and we posted it, but readers have pointed out that it old and it is vaporware. In fact, Wired covered it in November 2003 and Seqway called it vaporware then. We apologise- it's that treehugger instinct to recycle.
Bombardier may be reviled by Treehuggers everywhere for inventing the Ski-doo and the Sea-doo, but if you like fast-moving vehicles they are pretty innovative. The new Embrio uses gyroscopes longditudinal stability and a little training wheel for starting and stopping. Of course, it is powered by a hydrogen fuel cell. ::Funfurde
