“…Lockheed Martin developed a nuclear fuel-fired TPV system using GaSb cells and a tandem filter (Teofilo et al, 2006). On the other hand, TPV systems have also been considered for civilian as well as industrial applications in developed nations like Japan, U.S.A., and some other EU countries (Coutts, 1999;Yugami et al, 2003). In February 2006, engineers at Sandia National Laboratory, U.S.A., developed a TPV device which can generate 1.3 mW power from a tiny 900 K radioactive pellet, with an ultimate potential of generating power densities greater than 10 kW m À3 .…”

SUMMARYFast depleting reserves of conventional energy sources has resulted in an urgent need for increasing energy conversion efficiencies and recycling of waste heat. One of the potential candidates for fulfilling these requirements is thermophotovoltaic (TPV) devices. TPV devices generate electricity from either the complete combustion of different fuels or the waste heat of other energy sources, thereby saving energy. The thermal radiation from the emitter is incident on a TPV cell, which generates electrical currents. Applications of such devices range from hybrid electric vehicles to power sources for microelectronic systems. Absence of any moving parts and versatile fuel usage has made TPV devices very appealing for military and space applications. However, the presently available TPV systems suffer from low conversion efficiency. A viable solution to increase their efficiency is to apply microscale radiation principles in the design of different components to utilize the characteristics of thermal radiation at small distances and in microstructures. In order to have a clear understanding of microscale radiation and its role in TPV devices, several critical issues are reviewed in the present work. Emphasis is given to the development of wavelength-selective emitters and filters and the aspects of microscale heat transfer as applied to TPV systems. Recent progress, along with challenges and opportunities for future development of TPV systems are also outlined.

“…After our findings were made, Yugami et al followed up on our work, and utilized nano-cavities of a high-temperature-resisting material for the effective emission of relatively short wavelength radiation [24]. Recently, a similar investigation and numerical analysis were carried out by Hanamura and Kameya [25] The heat conduction of electrically non-conducting material or dielectric material can be described by phonon transfer.…”

Micro-and nano-scale systems are explained and are categorized in terms of heat and fluid flow phenomena. Some typical applications of nano-and micro-machines are presented. Heat and fluid flow phenomena of nano-micro spatio-temporal systems are described as follows. Micro-systems:• The size of the micro-machine element ranges from 1 µm to 1 mm.• The fluid motion and heat transfer can be treated as a continuum, and is described by Navier-Stokes equations and Fourier's law. Nano-systems:• The fluid cannot be treated as a continuum.• Discontinuity and wave characteristics of fluid and energy have to be considered.
