<p>PROBLEM TO BE SOLVED: To provide a gravity engine road enabling an automobile having no engine to run under effective utilization of inexhaustible gravity that can be found anywhere.SOLUTION: When a car runs over a signal 1, a movable road rises. A car 2 is pulled by gravity of the earth and runs down fast on a slope. When the car comes to a position slightly before a signal, a front movable road descends to cause the road to become flat and the car passes through the signal as it is. Soon after this operation, the movable road rises and the car again descends the slope fast. This continuous operation causes the car to run without any engines in this gravity road section, so that no contamination of air occurs.</p> |
