. Engaging the current technology-hungry college student is thus promising,possible and necessary; but with over 100,000 applications available for the iPad alone, criticalquestions remain. What applications, tools and methods truly enhance the learning environmentand what educational benefit, if any, do the students receive through the use of these devices?How do we integrate these devices in a way that appeals to our students, Prensky‟s “digitalnatives”4, when most of our professors are “digital immigrants”, without placing unmanageableburdens on the instructional team? The current literature examines the use of tablet devices in the college classroom but nostudy focuses on the use of iPads in the engineering classroom. An

suggests a mechanism design to achieve higher deflection. The paper will discuss thefirst two models. In conclusion, the paper points out how engineering education could benefitfrom exposure and participation in such a design process even though students were not involvedin this study originally.IntroductionThermoelectric generators convert heat to electricity. Current geometry and materials used indesigns shown in figures 1 and 2 result to rigid devices. The geometry ensures no moving partswhile the materials provide a high figure of merit (ZT). ZT=S2σ/k, where k is thermalconductivity, σ is the electrical conductivity, and S is the Seebeck coefficient. The figure ofmerit, ZT, is dimensionless and is formed by multiplying Z with the average

an input to the table, such as temperature, the properties are less certain than the 5or 6 digits. When a modest uncertainty of 0.2% for temperature is assumed, the properties arecertain to at most 3 to 4 digits, but not more. The same can be shown for steam.Uncertainty of Steam PropertiesIn the superheated steam tables, property data (v, u, h and s) is often given in pressure “blocks.”Students find the correct pressure block, then the line for the appropriate temperature to look upthe other properties. Although two other intensive properties can be used to fix the state, the Page 23.746.8most common are pressure and temperature; hence

Itmight be akin to having the physicians taking medical history and vital signs, while difficultdiagnosis is referred to the nursing staff (or physician assistants).
