Germany, known for exporting cars and beer, is also addressing the more basic needs of international consumers—its public toilets.

　　Clients in the United States, the Netherlands, Hungary, Poland and Turkey are already using green high-tech cabins, which look like giant elevators.

　　"Before we had these toilets, it was a nightmare to find a public loo1 in Berlin," said Horst Lemke as he rolled out in his wheelchair.

　　The toilets, the world's smallest, fully automatic toilets with wheelchair access, have been an export hit with 250 cubicles already built around the world.

　　Electronic music plays inside the cubicles and the toilet cleans itself after each usage. Water floods out of the walls and washes over the floor. Also there are sensors that would prevent anyone being locked inside.

　　"The doors open automatically after 20 minutes. That gives you all the time to even read a newspaper if you want. And a recorded message gives you an advance warning that the doors will open so that you can pull up your pants," an engineer said.
