When the top eggheads at Bombardier (a Montreal-based company that designs ATVs and jet skis) were asked to envision commuter transportation 25 years from now, they rolled with it. The Embrio Advanced Concept, a hydrogen-fuel-cell-powered, gyro-stabilized vehicle, makes your neighbor’s Segway look like something out of the Steam Age. At a stop, the Embrio relies on a wheeled â€landing gear†to stay upright. Above 12 miles per hour, the landing gear retracts, letting you one-wheel along at highway speeds. The unit was meant as inspiration for industrial designers who dream of one-upping Dean Kamen’s baby. For now though, this Embrio is still in utero–no working model yet exists.
