plasma and its application in magneto-hydro-dynamical generators

the increasing growth of the population around the world during 20th century and fast consumption of energy, now, is considered as the basic reasons of raising energy problems. this issue has affected all human life aspects. that is why we need energy to replace it with older and ending sources such as oil. meanwhile, it is easy and less-expensive to obtain it. in this direction and following widespread and continuous studies by scientists and researchers, the electricity generation by using plasma (magneto-hydro-dynamical generators) has been considered to achieve higher efficiency in production and less pollution. the present research is to make readers get familiar briefly with mhd generators and express that applying this generator, it is possible to offer an electric energy with high and, first of all, pollution-free efficiency to the society, if and only to get access to its technology. in fact, mhd is a process to convert energy directly into electricity with no need to a turbine or normal generator.
