19-year-old Jesse Van Kuijk designed a zero-emission aircraft that runs on pedal power.

Made out of lightweight Balsa wood, polyurethane and light rip-resistant foil, the plane weighs 56kgs and managed to lift a few mteres off the ground before the bicycle chain, which powers the propeller gave way, sending the aircraft back to the ground.

Not recommended for long-distanced travel.
