Sky Cruise: How a Nuclear-Powered Sky Hotel Could Change the Future of Travel
Imagine a cruise ship that can fly around the world, offering its passengers stunning views of the Earth and the sky, while providing them with all the amenities and entertainment they could wish for. This is the vision behind Sky Cruise, a concept for a nuclear-powered sky hotel that could revolutionize the future of tourism and aviation.
What is Sky Cruise?
Sky Cruise is a concept for a gigantic flying resort that was conceived by Tony Holmsten about 11 years ago and was recently animated by Hashem Al-Ghaili. The aircraft is equal parts spaceship and ocean liner, and it comes with just about every feature you could imagine. Its enormous size can accommodate more than 5,000 guests, who would arrive on board via commercial or private plane (that’s right—jumbo jets would land on top of the Sky Cruise). As for what you would get to enjoy once checked in, the views are quite obviously the biggest selling point. An elevated deck would provide a 360-degree vantage point for seeing everything from the stars to aurora borealis. From there, an elevator would take you down to the main entertainment deck, which looks like a cruise ship on steroids. You’d have access to shopping malls, sports centers, swimming pools, restaurants, bars, playgrounds, theaters and cinemas.
How does Sky Cruise fly?
One of the most remarkable aspects of Sky Cruise is its propulsion system. The aircraft is designed to use nuclear energy, which means it would be able to stay afloat—without landing—for several years. Twenty electric engines would be powered by nuclear energy, with a small nuclear reactor on board using highly controlled fusion reaction to provide unlimited energy. The reactor draws heavily from the design and lessons of the 2018 Kilopower Reactor Using Stirling Technology (KRUSTY) demonstration led by NASA and the DoE’s National Nuclear Security Administration.
The electric engines would generate thrust by passing current through large amounts of copper wiring and steel to create magnetic fields that can turn a rotor. The rotor would be a circular drum with an interior surface lined with permanent magnets. The rotor would spin inside a stationary ring called the stator, which would also have copper wiring and steel. The interaction between the magnetic fields of the rotor and the stator would create torque, which would then be transferred to a propeller or a fan.
The electric engines would have several advantages over conventional jet engines. They would be quieter, more efficient, more reliable, and more environmentally friendly. They would also enable distributed propulsion systems, which means that the engines could be placed in different locations on the aircraft, such as the wings, the tail, or the fuselage. This could improve the aerodynamics, the stability, and the safety of the aircraft.
What are the challenges and benefits of Sky Cruise?
Sky Cruise is still a concept, and it faces many technical and regulatory challenges before it can become a reality. One of the main challenges is the safety of the nuclear reactor and the high-voltage systems on board. The reactor would need to be shielded to protect the crew and the passengers from radiation, and the electrical components would need to be insulated and cooled to prevent overheating and short circuits. The reactor would also need to be designed to withstand extreme conditions, such as high altitudes, low temperatures, and potential crashes.
Another challenge is the certification and approval of the nuclear-powered aircraft by the authorities. The United States has not flown a reactor in space since 1965, and there are no existing airworthiness standards for this design feature. The FAA has recently released special airworthiness conditions for electric engines created by magniX, a company that is developing electric propulsion systems for smaller aircraft. However, these conditions are specific to one particular company and product, and they do not address the nuclear aspect of the propulsion.
Despite these challenges, Sky Cruise could also offer many benefits, both for the passengers and for the environment. For the passengers, Sky Cruise could provide a unique and unforgettable travel experience, with unparalleled views and comfort. Sky Cruise could also offer more flexibility and convenience, as it could fly to any destination without the need for refueling or landing. For the environment, Sky Cruise could reduce the carbon footprint of aviation, as it would use clean nuclear energy instead of burning fossil fuels. Sky Cruise could also reduce the noise pollution and the congestion of airports, as it would operate independently of the ground infrastructure.
Conclusion
Sky Cruise is a concept for a nuclear-powered sky hotel that could change the way we travel and explore the world. It is a visionary and ambitious project that combines advanced technologies and innovative designs to create a flying resort that could accommodate thousands of guests. Sky Cruise is still a concept, and it faces many technical and regulatory hurdles before it can become a reality. However, it also has the potential to offer many benefits, both for the passengers and for the environment. Sky Cruise is a concept that challenges our imagination and inspires us to dream of new possibilities for the future of tourism and aviation.
