Japan NHK Sunday Forum (Education TV) came on the air that the title was Electric car changes our society on September 16.The program was taken one hour in Sunday evening, and 5 members of the panel spoke about electric car from their each technical standpoint. 5 members are composed of two professors (one is female) of university, industrial designer, car critic and nonfiction writer. I had very interested in the program because it appeals the preventing of warming climate.Some points of this program were these.1 Tokyo Electric Power Co. is researching and developing for new electric car, and some prototype mini- cars were made and used actually as practical use testing at Yokohama branch office in Japan.2 The car has lithium-ion battery. It runs approximately 80Km by one charge, and it takes about 15 minutes for quick charging. Usually the car is charged in parking area during the night. The cost of one charge is about 65 US cents (80Yen).  The accelerating performance etc are as same as conventional car.   But this new car is too silent.3 The cost of this test car is about 48,000 US dollars now, but on 2010(for practical application use) it will be reduced to 24,000~16,000 US dollars(1dollar is 125yen).4 The material of magnetic steel plate and the configuration which is used in new electric motor was developed, the thickness of new magnetic steel plate is 2mm~1.5mm(traditional type is 4 mm.). The new magnetic steel plate is very hard just like stone, so special strong press machine is prepared to produce this.   As the result, the efficiency of electric motor increased up to 20%.5 In Kathmandu of Himalayan kingdom, people had breathing disorder by emission of taxi car(small 3 tires car) which was used fossil fuel, then these 2,000 cars engine were changed to nickel-zinc cell battery.6 In Tokyo University researches a future new concept car which each tire has individual micro processor to control itself and these micro processor are controlled by main PC to keep car safety and efficiency.The general outline of this program was these.             We must find out any factors of warming climate and solve these problems, and also we do change firmly our daily life to recover the nature step by step.
