Although our RE-Brakesystem worked for us, it lacked portability and was not interchangeable between bikes. Wedesigned RE-Brake specifically for our bike and all the measurements that we took matched ourdesign and layout, however, our next goal would be to make RE-Brake more modular and to haveit easily fit on various bikes and models.Once the RE-Brake system was attached to the bike [Figure 2a-b], three different tests were run.The first test was

The measured parameters (See Table 1) were analyzed to determinecorrelations (See Figure 2) and cost of water heating (See Table 2). It ultimately culminated tocost of $0.92 and took one hour, twenty three minutes and twenty four seconds to heat thirtygallons of water from 30C to 70C.

Part of this success is attributed to devoting the first laboratory session eachsemester to electrical safety. Using a presentation developed by author DeWitt, the students areshown both real and dramatized electrical accidents, and aspects of electrical hazards and safetyare discussed in detail. Despite the emphasis on safety, however, there have been a number ofarcing incidents (probably once every three semesters on average) during the years.

Questions the students needed to answer included explain-ing why steam or water injection is recommended. The students will discover that—as a resultof the first law of thermodynamics—the same total power input is required for both options, butthe final questions challenge the students to consider the actual application. For example, studentsare asked to consider a retrofit to convert an existing steam injection system to a water injectionsystem and comment if the existing heater can be used. Students
