    The document discusses magneto hydro dynamic (MHD) power generation as a non-conventional energy resource. MHD generation works by inducing an electric current when an electric conductor moves through a magnetic field, similar to a conventional generator. It describes open cycle MHD which exhausts hot gases into the atmosphere after steam generation, and closed cycle MHD which continuously circulates working fluid. Advantages of MHD generators include having no moving parts and ability to reach full power instantly. Applications include power generation for spacecraft, defense, and hypersonic experiments. MHD is presented as a potential solution to increasing power demands and reducing pollution from coal and nuclear plants.

    INTRODUCTION
    The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. Generation of electrical power by coal based steam power plants or nuclear power plants causes pollution, strongly suggests the harnessing of non conventional, renewable and environment friendly energy resources This paper describes the magneto hydro dynamic power generation which is a new unique method of power generation which is said to be high efficiency and low pollution.

    PRINCIPLE OF WORKING OF AN MHD GENERATOR


    The principal of MHD generation is simple, discovered faraday when an electric conductor moves across a magnetic field, an e.m.f is induced in it, which produced an electric current. This is the principle of conventional generator also, where the conductors consist of copper strip.

    TYPES OF MHD GENERATORS


    The MHD generators are classified into two groups as Open cycle MHD Closed cycle MHD

    OPEN CYCLE MHD


    In this system the gaseous fuel produced from coal gasification plant is supplied to the combustion chamber where it is burnt in the presence of high pressure air (5ata). The heat of the hot gases coming out from MHD is used for steam generation before it is exhausted into atmosphere

    CLOSED CYCLE MHD


    The working of the system is exactly similar to Open cycle MHD except the working fluid is continuously circulated in the cycle instead of exhausting to the atmosphere. As there is no loss of working fluid this can be chosen for its better heat transfer and electrical properties. The closed cycle MHD retains the seeding element, gives pollution free operation and saves exhaust heat.

    ADVANTAGES OF MHD GENERATOR


    No moving part, so more reliable. As there is no limitation to the size of the duct, so high capacity generators are possible. Ability of reaching the full power level instantly. Conceptually these generators are very simpler.

    APPLICATIONS
    Power generation in space craft. Defense application. Hypersonic wind tunnel experiments

    CONCLUSION
    With the increased industrial and agricultural activities, power demand is also highly increased. In the country is sure to fall short of the energy demand by the first decade of next century. The answer to this is in non conventional energy.
