Spirit of Amsterdam 2
The Spirit of Amsterdam 2 is the second vehicle built by the Hogeschool van Amsterdam. It uses a wind turbine to capture the wind velocity and uses mechanical power to propel the vehicle against the wind. This vehicle is capable of driving 6.6 meters per second with a 10 meter per second wind.
Next to its reduced weight, the main advantage is the onboard computer with its sophisticated control system. This specially designed computer is capable of automatically shifting gear in a fraction of a second, and by this the gears are always shifted to their most efficient position.
