As reported earlier this year, the rather smart ENV fuel cell-powered motorcycle is set to begin gliding down your streets by the end of 2006.

The London-based company Intelligent Energy decided to develop the bike itself after years of cool reception to its fuel cell technology from manufacturers. "We wanted to show how good the technology is right now and basically build what we thought would be a technical example, albeit an example that's wonderful and stimulates interest," said Andy Eggleston, ENV project director.
