China successfully test Hydrogen Fuel drones

Chinese hydrogen-powered drone stayed in the air for four hours and set a Guinness World Record Chinese hydrogen-powered drone stayed in the air for four hours and set a Guinness World Record

This is normal consumer size drone and it kept flying for 4 hours covering over 180km.

Reminds me of Terminator 3 scene when Arnold kills the T-X by putting the hydrogen fuel cell into her mouth.

That was some very exaggerating tech concept imagining Hydrogen fuel cell as a portable fusion reactor which was overloaded.
