The original 06-0692 were a brittle plastic with curved blades that caused a good flow of air when driven by a 37-0144 motor. These are more pliable, so less breakable. Used with a "solar" motor (37-0441) as a dynamo, they give over 2V when blown by mouth, but are no good for providing an airflow. For this, the 06-0690 are quite good when the blades have been immersed in hot water and twisted about 60deg.
