Stranded Without Food? Edible Drone Has Snackable Wings
The munchable machine could be used in rescue missions.
To make the wings, the researchers trimmed up round rice cakes using a laser cutter and glued them together with gelatin to create a wing structure that could hold up to flight. The rice is strong, but lightweight and still reasonably nutritious. The drone would be a one-way proposition, but the partially edible nature means there wouldn’t be a lot of debris left behind.
The idea of edible drones has been kicking around for years. We met a chocolate quadcopter back in 2014 and a UK aerospace company talked up an edible drone called Pouncer in 2017.
