A system comprising a tunnel implement for immersion in a moving mass. Energy from the moving mass passing through said tunnel implement is converted to rotational force. A collector device is provided having open and collapsed states, wherein the open state resists the moving mass. A rotational converting device converts the rotational force to constant singular direction. An input shaft is turned bidirectionally by the rotational force and two gears driven by the input shaft in opposite rotational directions, the gears separately attached to idler gears causing output gears attached to the idler gears to engage an output shaft in a same rotational direction. A bidirectional drive motor device drives a pulley device in a predetermined direction. A sensor device senses the position of the collector device. A trigger device is configured to activate said sensor device to indicate the collector device position and state, whether opened or collapsed.
