With traditional sources of energy facing a sheer decline in recent decades, vehicle designers have now started thinking seriously about the alternative fuels their concepts should rely on. Among options, there are wind, solar, thermal, hydrogen and the rest. Danish industrial designer Niels Grubak Iversen, however, places his money on the last alternative as he comes up with an interesting motorcycle concept that relies on a hydrogen-powered internal combustion engine for the much-needed driving force.

Dubbed as Buell H2, the advanced café racer takes biking to its next level, which is so very evident from a sci-fi-inspired styling. Mind you, the engine discussed-above betters the V2 HD engine beyond a measure.
