Global increasing of temperature today is a fact we all should be aware about. In general it has never been defined, but while scientists having discussions about increasing and decreasing of the global temperature people still suffer from heat. Every person is fighting with it in his or her own way. Some buy conditioners and funs others swim in pools and having showers during the heat.

Recently Japanese scientists made the successful experiment. They watered a road with the length of about 350m with sprinklers that where installed along the flank of it. The road before was covered with the special composition that does not let the water to be absorbed into. And as a result the surface of it was cooled on 10 degrees and air under it was cooled on 1 degree lower. Inventors are going do such thing all over the Tokyo's streets and below general temperature in the city.

I think that for the better results they can use big coolers as in computers. For people who live in metropolises
