Innovative cars (Part 1)
A century has passed since the creation of the first serial car by Carl Benz and the mass production of Ford cars with low prices for all Americans. During this period of time cars became so widespread that it begins to pose a threat to the environment. In addition, a huge crowd of cars creates a problem for residents in large metropolitans, which confront face to face with daily traffic congestion, noise, and vibration. It is all a price, which society must pay for benefits connected with automotive. For example, the main benefits of tracks in freight transport is a possibility of moving goods practically in any place, the main requirement is the road infrastructure, which is unrealistic in case of rail transportation. It is impossible to provide the presence of cargo terminals and other railway infrastructure in all settlements. Even though suppose, that railway infrastructure will be in all settlements; there would be problems with transporting goods from terminals to final destinations (stores, warehouses, factories).
The automotive industry has made a huge step forward to reduce the negative impact on the environment. These changes occur even before the tightening of environmental standards by authorities. Since the 1990s, only thanks to EURO norms, the volume of СО2 emission has decreased from 3.16 g / km to 1 g / km. In the field of public passenger transportation and personal transport, has been a huge movement for usage of electric energy. Today the effectiveness of this approach for the protection of the environment is questionable, because the electricity, in any case, is generating mainly by hydrocarbons (40.8% - coal, natural gas - 21.6% ). The efficiency of the electric motor is equal to the efficiency of the internal combustion engine. The only difference between electric and classical car is that the "exhaust" is somewhere far away, and air in large cities is clear. Thus, the global environmental friendliness depends on a type of power station, which generate electricity, in the case of classical coal power station that all comes to naught.
