Direct Energy
This text discusses the physics behind energy conversion processes and a wide variety of energy conversion devices. it first surveys multiple devices that convert to or from electricity including piezoelectric devices, antennas, solar cells, light emitting diodes, lasers, thermoelectric devices, and batteries. This book puts concepts of energy conversion in a more abstract framework and introduce the idea of calculus of variations and illuminate relationships between energy conversion processes.
