Über dieses Buch

This book discusses the history of thermal heat generators and focuses on the potential for these processes using micro-electrical mechanical systems (MEMS) technology for this application. The main focus is on the capture of waste thermal energy for example from industrial processes, transport systems or the human body to generate useable electrical power. A wide range of technologies is discussed, including external combustion heat cycles at MEMS ( Brayton, Stirling and Rankine), Thermoacoustic, Shape Memory Alloys (SMAs), Multiferroics, Thermionics, Pyroelectric, Seebeck, Alkali Metal Thermal, Hydride Heat Engine, Johnson Thermo Electrochemical Converters, and the Johnson Electric Heat Pipe.

Chapter 1. An Introduction to Waste Heat Capture and MEMS
Abstract
Waste heat is all around us. Every energetic process, regardless of its initial form (kinetic, chemical, or electrical), eventually ends as heat, which eventually degrades to ambient temperature. In many situations, the heat could be captured and converted to electrical energy.

Chapter 2. Established Thermomechanical Heat Engine Cycles
Abstract
This chapter describes and discusses the four most common external combustion thermodynamic cycles: Stirling, Brayton, Ericsson, and Rankine. Internal combustion thermodynamic cycles, such as Otto, Diesel, and rocket, will not be considered, because it is impractical to use them for waste heat capture.

Chapter 3. Other Thermomechanical Heat Engines
Abstract
In Chap. 2, the discussion centered on traditional heat engine cycles that were developed at large to very large scale for industrial power generation. This chapter discusses smaller scale methods of converting a thermal difference into mechanical energy that are applicable at a micro-electro mechanical systems (MEMS) scale. The methods examined include thermomagnetic engines, shape memory alloy (SMA) engines, and hydride heat engines.

Chapter 4. Mechanical to Electrical Conversion
Abstract
As described in Chap. 3 many methods of harvesting thermal energy convert heat energy into mechanical energy; often, this is vibration. While mechanical energy may be of use in some systems, an additional stage of converting energy from mechanics or kinetics to electrical energy is generally required. In this chapter, devices that convert mechanical energy to electrical energy will be referred to as transducers.

Chapter 5. Thermal to Electrical Energy Converters
Abstract
The previous chapters discussed the generation of mechanical motion from thermal energy and the subsequent conversion of this to electrical energy. The additional step from thermal to electrical energy can introduce further losses, reducing overall efficiency. In this chapter, the conversion of thermal energy directly to electrical energy is discussed.
