Miquel Ros wrote about floating airports:

• The problem with airports is that they’re most useful in areas that are the least likely to have space for them – densely populated urban cities.
• But many of the world’s top cities are also located close to large bodies of open water.
• Some people have long been trying to put two and two together and build floating airports.
• The technology is there – after all, we figured out aircraft carriers.
• And while a floating airport would have to be a lot larger because commercial airliners need a lot more runway, they should be easier to build since they can be stationary and don’thave to be able to conquer territory.
• Since such an airport would be built on the water it could power itself using the entirely environmentally friendly power of the waves.
• You’d have to connect the airport to the land of course, but that could be done through underwater tunnels.
• As with most exciting ideas the number one problem is finding an affordable way to make it.
