This text investigates the fundamental physical principles and engineering mechanisms required to convert various forms of energy directly into electrical power without the use of intermediate heat engines. M. Ali Kettani provides a rigorous academic framework for understanding the conversion processes that bypass traditional thermodynamic cycles. The book synthesizes theoretical physics with practical engineering applications to explain how energy sources like solar, thermal, and chemical potential are transformed into usable electricity. It serves as a comprehensive reference for researchers and students examining the efficiency and viability of non-conventional power generation methods.

Experts recognize this work as a foundational text for understanding the physics of non-mechanical power generation. Readers frequently note the high level of technical density and the necessity of a strong background in electromagnetism and thermodynamics to fully grasp the material presented.
