James Miller, a field service engineer with Miller Weldmaster, constructed bags for show attendees in order to demonstrate how a whitewater raft is made. "It's like a sewing machine without thread," he told me. "That's a way to think about it."
Jim, thanks for the links. That's about what I would have guessed based on the difference in materials: wider operating temperature/humidity range, but less rich/complex sound quality. That shows up in this video http://www.youtube.com/watch?v=kLOvXfSFuL0 of Yo-Yo Ma playing the divine Bach on a carbon cello.
Thanks, Jen, wish I could play a cello. I'm a listener and appreciater of music, not a player anymore. What I'd love to find is an interview with Yo-Yo Ma about the carbon instrument. Will let you know if I do!
Jennifer--This looks like a fascinating convention. Thank you for the slides. I definitely think the political types and talking heads in Washington need to step back and take another other look at American ingenuity--American creativity. At times, it seems they have relegated manufacturing to the endangered species list when in reality, it's alive and well and in some circles thriving. Your slides certainly bring that into focus. I write a blog on engineering education in our country and across the world and we remain the example for the civilized world. We are what they hope to be--someday. Again, many thanks for the update.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
