Polypack Inc. brought a sports theme to the packaging show with polyethylene wrappers designed to look like baseballs, basketballs, and footballs. The sports wrappers can be used for juice packs and canned goods.
Packaging engineers must be a quiet bunch, bobjengr. In popular culture, there's nary a mention of packaging engineers. You wouldn't know they exist if there were no trade journals. Yet, here we have 43,000 engineers showing up for Pack Expo.
Chuck--This looks like a terrific show. 43,000 + has to exceed their expectations. In just about every place I have worked over the years, packaging has been somewhat of an afterthought. At GE Appliances (Roper Corporation) we did have a packaging engineer but that was only one of his responsibilities. In the appliance industry a good number of the DOA problems have been due to transportation issues and not relegated to product design. Great post and thank you for showing it.
I should have been clearer in stating my question: I know there are tradeoffs in general, but wondered what they were with this specific battery. OTOH, glad you replied in detail because now I know more, especially about top speeds and how to get there. Thanks!
I don't know what the range of the motorcycle is either, Ann. As to your question about the tradeoff...yes, there is absolutely a tradeoff between power and energy. In some cases, one is realized at the expense of the other. By boosting a battery's current collector and reducing the amount of active material, EV designers can provide the amps needed for high torque and fast launch. But when they do that, they diminish the battery's energy density and, therefore, its ability to drive longer distances. Having said that, I don't think that's the case here. Electric motorcycles have gone much faster than the BOLT. An electric motorcycle called the KillaCycle hit a speed of 168 mph four years ago, and I'm quite sure the figure is much higher now. I have little doubt that en electric motorcycle could hit speeds in excess of 200 mph (if one hasn't already) by making the battery changes I described above. I don't know about this specific battery, however, having only seen it at the Kollmorgen booth at Pack Expo.
Chuck, my question was regarding whether there's a tradeoff between acceleration/top speed--needed in a racing bike like this one-- and the range. I spent some time Googling to find out what the range is, without success. Do you know?
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
