Abstract: A cylindrical wind-turbine has an intake opening set in a known direction of oncoming wind (such as towards the direction of an expected oncoming train). A central plunger acts as a valve to regulate airflow, and may seal the intake opening. Exit valves are situated near the rear of the device and/or at the rear in embodiments of the disclosed technology. The intake opening and exit valves may be opened or closed depending on readings from wind and water sensors. Generally speaking, when there is sufficient wind and low threat of water, the openings and valves are open, collecting wind energy. When there is a lack of wind or presence of water, the openings and valves are sealed to protect the interior components of the device from the elements and unnecessary wear and tear, prolonging the life of the device.
