Correct answer: C. Magneto hydrodynamic generator
- A. Fuel cells
- B. Photo voltaic cell
- C. Magneto hydrodynamic generator
- D. None of these
Explanation
A magnetohydrodynamic generator converts the thermal energy of a hot, electrically conducting gas directly into electricity through its motion in a magnetic field. Fuel cells convert chemical energy, while photovoltaic cells convert radiant energy.
