A homemade solar drone has just broken its own record, flying for more than 5 hours straight.
Last year, Luke showed that a drone can fly using only sunlight, without any battery.
This time, he improved the design and made several upgrades to test how long it can keep flying on a sunny day. The goal was to push the drone to its limits and achieve maximum flight time.
Why it matters:
This shows that solar-powered flight is becoming more practical. In the future, drones could remain in the air for extended periods without landing or recharging, which could be useful for surveillance, communication, and environmental monitoring.
