"Boarding is completed" is a common refrain heard over the intercom system in the moments before taxiing to the runway.

At that moment, the pilot will begin a series of engine tests and pre-flight checks during which time the turbine engines are idling with their ferocious noise and exhaust fumes.

A company called JetWind has realized that all that idling force is like the strong winds needed to power a wind turbine, and has built a series of pods that can capture it during the 5-10 minutes the aircraft is sitting at the gate waiting for clearance to taxi.

"The main goal of our project is to harness the consistent wind created by jets and convert it into an eco-friendly energy source," JetWind's founder and president Dr. T. O. Souryal told Interesting Engineering.

"What was once considered wasted energy can now benefit energy grids, ultimately promoting smarter and more sustainable infrastructure across the globe."

Three years of testing between 2021 and 2024 have informed the official deployment of JetWind's flagship product at Dallas Love Field airport. 13 sets of pods will sit beneath the gate hooked up to external batteries that connect to the grid the airport uses. Solar panels add to the energy generation, and the whole set can create about 30 kilowatt-hours of renewable energy, enough to power a family home for a few days.

While on its own it isn't nearly what the average airport will consume during a day of operations, when combined with 12 other systems just like it, it can make a serious difference in reducing the carbon footprint of the building.
