Abstract:
A drive assembly for providing a driving force includes: a first track declined in a first direction through a first declination; a second track, extending in a second direction and arranged to pivot with respect to the first track between a first position in which the track is substantially horizontal and a second position in which the second track is declined in the second direction through a second declination; and a shaft connected to a flywheel and. A first vehicle is arranged to travel along the first track between a first drive location and a first idle location to drive the shaft in a first direction and to cause a second vehicle to travel along the second track between a second idle location and a second drive location; and, the second vehicle is arranged to travel along the second track from the second drive location to the second idle location to cause the shaft to rotate in a second direction and to cause the first vehicle to travel from the first idle location to the first drive location. The shaft is coupled to the first and second vehicles and arranged to rotate in dependence of the travel of the first and second vehicles.
