11.1320.5 PBASIC is easy to use and has good help system; examples of code can be cut and pasted inthe active programming window, and tried out. The PBASIC software and Excel add-in programare free and can be downloaded from the Parallax website3.Results and DiscussionInitial experiments were done to understand the behavior of the valve. In fluid mechanics,students will have learnt about flow through constrictions when dealing with flow meters.Figure 2 shows the measured relationship between flow rate and pressure drop with the valvefully open for a particular valve. Over most of the flow regime, the flow is laminar and so therelationship may be represented by Q = Cv(x).∆PHere Q is the volumetric flow rate, Cv is the valve coefficient, x is

pluggedinto the power inverter (instead of the wall of the garage). A small Q hydrogen cylinder(with an internal volume of 14.7 L filled with compressed hydrogen at 2000 psi) wasused to power the fuel cell for slightly less than one hour. This power was adequate topower the e-Gator and prevent the batteries from losing charge. Pictures of the vehicleare shown in figure 3 below. Figure 3. John Deere e-Gator with fuel cell power unit as the payload.At this point the TACOM funding period expired and the students began to seekadditional funding. With the guidance of the faculty advisor, students contactedcompanies to initiate discussion. The majority of the minor project teams were paperstudies of alternative energy areas. If the contact seemed
