     The International Space Station allows astronauts to live in space for extended amounts of time,

enabling them to explore the outside universe and conduct many experiments. However, nothing like that

exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what

lies undersea for very short periods of time.

     They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon. 

     Jacqucs has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge 167ft ship, named 'Sea Orbiter', consists of two areas-one

above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where

scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to circumvent the globe.

     Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the

latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD

player. And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an

accomplished chef, plans on cooking them delicious meals every day.

     The biggest problem to this giant ship is the cost, which is expected to be over $500 million-per ship!

However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global

warming and a vital supply for food and medicine in the future, is confident he will be able to convince

governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon!
