Wind turbine is a good choice for energy harvesting on trains. The air flow is generated by the train movement and it is quite simple to find places with high flow speed near the wireless sensor nodes location which are typically mounted on bogies and wheelsets. The requested amount of energy is relatively small, in the order of 0.01–0.05 W, allowing for wind turbines with very small diameter, between 2 to 6 cm. In the present work a newly designed turbine is described. The turbine is placed in a duct with protection purposes and it has a symmetrical design that results in power production independently from the train movement direction.
