TheASU team and KNUST faculty and students involved in the project visited the village of Biemso,met with the Chief who had donated the necessary land, and visited the Jatropha fields, whichwere just being readied for planting. The seedlings are shown below in figure 1. Figure 1. Jatropha Acreage near BiemsoUpon returning to the United States, the team contacted the ASU Barrett Honors College to seeksupport for the project, and the student team was assembled.

project is intended to be a comprehensive study. The coursefocus is unambiguously design. Analysis is used as a tool in the design process. The course goals and objectives are provided in written form to the students at thebeginning of the course. They consist of the following: Goals: 1. To utilize the tools of thermodynamics, fluid mechanics, and heat transfer to create a conceptual energy systems design for an existing structure, or for a proposed structure or development 2. To generate a report that can be of value to developers, planners, or other interested parties. The objective of the course is to give the students experience in the

Mayborn Museum provides an outstanding venue tostage the results.Construction of the Wind and Solar Exhibits for the Mayborn MuseumThe wind and solar exhibits for the museum were constructed as part of the senior capstonedesign class. “Senior Engineering Design II” is divided into sections of between 10 and 30engineers of all disciplines. Each section is organized into a “company,” with a project manager,departments and department heads, a budget and a project client. In this case, the Museum servedas the client. The company was tasked to design and install, if possible, (1) a 1.1 kW (peak)photovoltaic (PV) array on the Museum roof, including a mounting structure to withstand 80mphstraight-line winds, (2) a mounting structure for a small

population and energy consumption both continue to grow significantly. Also, dueto global uncertainties, energy is becoming increasingly important. The United States, forexample, increasingly relies on imported energy (32.9 % in 2006)1. Projections from DOE’sAnnual Energy Outlook indicate that primary energy use in the United States will climb to 134Quadrillion Btu in 2030 from 98 in 20002. Despite increases in electricity generation efficiencies,total electricity consumption is also predicted to increase.

The interactive nature of the E-book allows students tochange motor and/or load parameters and repeat the problem in a short time.Buffalo State College recently acquired new electromechanical laboratory equipmentmanufactured by Lucas-Nulle12.

417 Design of Alternative Energy Systems is a senior level design intensive elective course[1]. It is a project based course for which the students carry out three technical projects. In itslast offering the projects were: design of a fuel cell system, design of a wave energy system, anddesign of a solar energy system. The focus of the course is for students to use simpleengineering principles in developing predictive models for alternative energy systems. Some ofthe projects require students to develop their own calculation tool (a spreadsheet or MATLABprogram), while other projects use commercially available software, for example spreadsheetprograms from RETScreen International [2], which is managed under the leadership and ongoingfinancial

Wethen investigated purchasing “name brand” replacement drives. Unfortunately, we found that Page 13.1341.2new drives were about $2000 apiece and software to connect them to the computers was evenmore. That was not an option, given that we have eight lab stations, so we began looking at otheralternatives.The drive we settled on is the Dura Pulse G3 drive, which ismade in China and sold by Automation Direct in the UnitedStates, and is shown in Figure 1.

Induction heating has been widelyapplied to industrial operations such as forging, heat-treating, soldering, hardening, and otherforms of heat transfer. As the oil shortage and global warming become imminent, many newalternating energy sources such as wind, ocean and solar requires better power management inthe energy conversion1.

The major way to meet this challenge is to build green.

There is ongoing debate over how long fossil fuel reserves will last, a fewdecades to a few centuries, depending on the fuel. But this debate is trivial, because they are allfinite resources that will eventually be exhausted. The only debate is how quickly society mustreact to the inevitable end of unsustainable consumption.The public is reluctant to plan for decades or centuries ahead, because personal financial andsecurity concerns are more immediate.
