Here is an interesting demo that Dr. Louie did last week. It involves a rare earth magnet and a copper pipe. As the magnet falls through the tube, there is a change in flux through the cross section of the pipe. This induces a current whose magnetic field opposes the change in flux. In other … Read more
Day 6 (Saturday June 11, 2011)
The academic year may be over, but the work of a humanitarian engineer is never done. Our goal today was to remove the rotors from their molds and continue working on the blades. There were about seven students, Dr. Louie, Vincent Van Acker and Carmen Cejudo of Engineers without Borders. We worked from about 10:30am … Read more
Day 5 (Saturday June 4, 2011)
Today our goals were to meet with the Boeing Aerodynamic Engineers, cast both of the rotors and improve and complete the blades. This would be chapter 11 and 15 from the “Homebrew Wind Power” book. There were four engineers from Boeing that came to Seattle University and gave us a lesson on aerodynamics. We had … Read more
Day 4 ½ (Tuesday May 31, 2011)
Today we met in the middle of the week to get some more blade work done and to caulk the second rotor mold. This would be chapter 7 and 15 in the “Homebrew Wind Power” book. Roughly 5 students stayed for the duration of two hours. The blade team did more chiseling and shaping of … Read more
Day 4 (Saturday May 28, 2011)
