“…Furthermore, thermoelectric devices are easily and accurately controlled. All these advantages, along with the fact that the prices of Peltier modules are constantly decreasing, boosted the development of highly interesting thermoelectric applications, competing nowadays in the civil market with good prospects for the future (Bell, 2008;Chang et al, 2009;Chein & Huang, 2004;Gordon et al, 2002;Hongxia & Lingai, 2007;Khattab & El Shenawy, 2006;Martínez et al, 2010;Min & Rowe, 1999, 2006Omer et al, 2001;Riffat et al, 2006;Vian et al, 2002;Vian & Astrain, 2009a, 2009bYang & Stabler, 2009;Yodovard et al, 2001). Regarding the last comment, it is common knowledge that efficiency of thermoelectric devices represents the key point to bear in mind, in order for these prospects to become reality.…”
