The Use of Train-Generated Mass Airflow to Produce Electricity
When wind power is mentioned, most of us think of the ‘classic’ tower plus blades design of above-ground onshore or offshore wind turbine generators. But, as this article about using the airflow generated by underground trains illustrates, there is potential to adapt wind turbine generator designs to harness ‘wind’ energy from other sources.

WWT Tunnel, LLC (WWT) of Pasadena, California, recently completed the third in a series of studies on behalf of the Los Angeles County Metropolitan Transportation Authority (LACMTA). The purpose of these studies was to confirm the feasibility of using the mass airflow generated by a subway train as it moves through an underground tunnel as a source for generation of renewable energy.
