Dusseldorf International Airport
Germany comes to mind when we talk of technology climbing one level up. The most interesting thing that the airport offers is robot valet parking. The valet, nicknamed Ray will park your car when you reach Dusseldorf airport.
After the traveller confirms on the touchscreen that no one is in the car, the robot measures the vehicle, picks it up with a forklift-like system and takes it to the back area to park it. Connected with flight data system, the robot valet knows when the customer will return, however, the customer can mark itinerary changes in the parking app.
The travellers have access to various amenities like 24 high-tech conference rooms, restaurants, bars, shops, business, banking, family and special needs amenities. The departure and central arrival areas are made accessible to specially-abled people.
The airport has 8400-panel solar array, a solar power plant generating almost two megawatts of energy per year and large monitors displaying the amount of energy the panels are generating and the carbon emission they are preventing.
