The invention discloses a turbo machine suitable for reheating and magnetofluid united power generation and poly-generation based on a multi-working-medium plasma method. A core technology of the turbo machine is integration of turbo machine closed power generation, plasma, magnetofluid power generation, a super-capacitor and an electrically controlled cooling system, namely a prime motor. The prime motor, an acid pyrolysis oxygen producer and a film-free electrolysis hydrogen producer (or hydrogen production through conversion) and regenerative fuel cell (or methanation) form a super prime motor. A heavy prime motor achieves double-machine united cycle. A multi-machine united power generator and a universal fuse salt gasifier are widely applied to high-value utilization of carbon-relatedresources of agriculture, forestry, animal husbandry, industry and urban and rural household garbage. The turbo machine is suitable for multi-working-medium poly-generation, a methane chlorination process combines with ethylene acetylene and plasma metallurgy to achieve ecological fusion of the two pillar industries of energy resources and materials. The prime motor replaces electricity use in thefields of fossil energy power generation, traffic, transportation, navigation, aerospace, industry and mining, enterprises, families, military, frontier defense and the like, 'two alternatives' of energy revolution are encouraged comprehensively, and the 'prime motor + hydrogen energy' clean energy unlimited zero-cost era is opened.
