World's largest underwater hotel

It looks like it could be something from an old James Bond film, but Polish company Deep Ocean Technology (DOT), are planning to make this idea a reality. 

The Water Discus hotel will not be the first underwater hotel, but is set to be the world’s largest. It will be built in Dubai, and consist of two main discs, one above water, the other below, and will have smaller circular modules connected to the above water section to provide additional facilities to the 21 hotel rooms located below the sea level. The main above sea disc will be supported and connected to it's counterpart by five columns and a main central shaft for stairs and lift.

The hotel will also boast a helipad, an underwater diving centre, with an airlock leading directly underwater, and a decompression chamber for training purposes. The nature of the design allows for the hotel to be expanded or even moved, with the surrounding discs having the ability to detach from the main disc and act as a buoyant life raft in the event of an emergency.

Hotel guests will be able to enjoy underwater views from their room, a submerged bar and even take a course in piloting an underwater vehicle.

DOT’s other ventures include designing underwater vehicles and equipment for seabed exploration.

Google starts filming underwater Street View

Mapping the world is a goal of Google and to take it to the next level they have started to map what is beneath the seas as well.

They have unveiled their first  images of their "underwater Street View" covering the barrier reefs in Australia, the Philippines and Hawaii, with more to come.
