Designer and aviation enthusiast Oscar Vinals has designed a triple-decker concept plane called the AWWA Progress Eagle, which he imagines could be implemented by 2030.

The imagined plane boasts a wingspan of 314 feet. Vinals also imagines the plane will be zero emission.

The plane's enormous wings could fold to make it easier for the maneuver through airports.

Currently, the largest commercial aircraft is the Airbus A380, which has a wingspan of 262 feet.

Compared to modern aircraft, which rely on fossil fuels, the Progress Eagle would employ six hydrogen engines to attain lift-off, then generate its own energy with solar panels -- which would line the room and wings.

The aircraft would also be fitted with a rear engine that would double as a wind turbine.

Built-in batteries would collect any extra energy. This would be recovered on the ground by special electrical storage trucks.

Vinals says the plane could conceivably house private rooms, restaurants and shops, and could resemble a hotel in the air.
