Researchers at the Korea Advanced Institute of Science and Technology recently demonstrated a fuel cell system that can power an RC plane for up to 5 hours on just 500 grams (17 ounces) of liquid hydrogen, and is expected to power a UAV variant of the plane for up to 10 hours when the autonomous pilot system in completed. KAIST hopes to use the tech in a future Korean military UAV, and, pending funding, expects to have a complete production-ready drone within two years. Sadly, there's no word on when Korean kids will be able to hold all-night drone-flying stamina contests, but we're waiting for that YouTube video pretty eagerly.
