If you prefer the luxury of hotels as you are not exactly keen on wiggly waggly sailboats, but would somehow like to float accross the oceans anyway, consider this option.
Designed by a London engineer-architect Gianluca Santosuosso, his MORPHotel is a floating hotel concept that looks like a vertebral spine and has its own self-sustaining ecosystem.
The hotel is in fact a morphologically adaptive vessel about one kilometer long. It is capable of "spiralling into itself and generating an artificial bay where boats and ships can find shelter." It's made of 'capsules', where guest accommodations and theaters, gardens, restaurants, and a swimming pool are situated. To top it all, there is also a helipad available as well as detachable boats for the priminent guests to leave the hotel and explore the intricate surroundings.
The concept predicts that MORPHotels would be constantly moving at slow speed around the world, using the sea currents. Tourists would be able to leave or get on board wherever the floating system lands, so that the line between visitng tourists and 'citizens' would fade in time, creating a new type of so-called 'tourizens' folk.
The designer stated that the aim of this project was to create "a big, independent, self-sufficient artificial organism," so he equipped it with solar panels (however, production of energy is also planned through the movement of waves) and rainwater harvesting facilities. The hotel would be able to produce certain types of food with each of the central vertebra containing a small vegetable garden. This part of the hotel would also work as a big floating farm where it will be possible to grow vegetables, rear animals and store foodstuffs.
So far there is no information on when such a system would be constructed and how much exactly would it cost.
