From the same people who brought you that amphibious car that Sir Richard Bronson made famous by crossing the English channel comes the Quadski. The Quadski can transform from an ATV into a jet-ski in 5 seconds. The vehicle, designed by Gibbs Technology can travel at speeds up to 50 mph on both land and sea. If we are lucky, one day someone will take this design and turn it into a reality.
