Yes, Boeing famously tested in-flight Wi-Fi using potatoes.
In a quirky but scientifically sound experiment, they filled a retired airplane with 20,000 pounds of potatoes to simulate human passengers.
🥔 Why Potatoes?
- Water content and chemistry: Potatoes absorb and reflect radio waves similarly to human tissue, making them ideal stand-ins for people during signal testing.
- No complaints or breaks: Unlike human test subjects, potatoes don’t move, sleep, or need bathroom breaks, allowing for uninterrupted testing.
✈️ The SPUDS Project
- Boeing dubbed the experiment SPUDS — Synthetic Personnel Using Dielectric Substitution — a tongue-in-cheek acronym that highlighted the tubers’ role as human substitutes.
- The goal was to identify Wi-Fi signal dead zones and optimize coverage inside aircraft cabins without risking interference with flight systems.
🧪 How It Worked
- Potatoes were placed in passenger seats across a retired aircraft.
- Engineers measured how Wi-Fi signals bounced, dropped, and behaved in a full cabin environment.
- The results helped Boeing fine-tune wireless systems for aircraft like the 777, 747-8, and 787 Dreamliner.
This oddball experiment is now a legendary example of engineering creativity — and a reminder that sometimes, the best test subjects are the ones you can mash, fry, or bake.
