Stump the Engineer
When I was younger, I always liked building things. Like every young engineer, I played with Legos and K'nex. Even before I graduated high school, I had graduated into building tougher things, including steel fabrication and stick built nitro airplanes amongst other things.
Despite what I thought I knew about the world at that time, I don't think I entirely understood what an engineer did. I always thought, "engineers build stuff". After going to school, I have learned that is not entirely true. Engineers design stuff. While there are many different types of engineers that perform many different services, in general, engineers are taught to use tried and true methods to optimize, invent, or improve products.
As you might imagine, there are many different types of products that exist in the world that an engineer has to be prepared to know how to work with, hence their education usually covers a wide range of subjects. I will be graduating in December with a degree in mechanical and aerospace engineering. My education has ranged pretty widely. Some of the topics I have studied over the last few years are: Fluid mechanics, Gas Dynamics, Thermodynamics, Materials, Basic Electronics, Hardware Programming, Electric Motors and controllers, Product Design, Aircraft design, Basic Rocket design, Complex Dynamics systems, Control systems, Hybrid Systems, and Auto Racing Dynamics.
Since this is my first blog, I thought it would be cool to take questions to gauge my audience. "How does _______ work?" "Why does ________product look like this?" "What is a __________ used for?" "Why do experts recommend people do ___________, when _______ occurs?" or whatever you come up with. I'll do my best to answer them. If there are any other engineers out there, you can see how good my responses are. Better yet, you should ask questions and try to stump me. ;D
I'll take questions about literally anything, but aircraft and electronics (hardware and software) will likely get the best response.

Ice Mountain Eco-Bottle
I saw an Ice Mountain bottle of water a few weeks ago.
As soon as I saw it, I thought it was a pretty blatant revenue strategy conveniently masked behind a marketing ploy and social trend.
The fallicy: 30% less plastic you say? It touches my heart that Ice Mountain could be so concerned with the earth, pollution, and bottle production emissions!
The reality: Bottle manufacturing plants typically charge by the volume of plastic required for your bottle. If you could reduce the volume of the bottle enough to reduce the cost of a bottle by just $.01 per bottle, and you produce 100 million bottles a year, you would save your company $1 million a year. Whodathunkit, Saving an absurd amount of money doesn't make your company look as good as being environmentally friendly. Some lowly engineer that makes 60K a year probably designed that bottle, and coincidentally created this crappy marketing ploy.
The fallicy: This bottle is more flexible making it easier to recycle?
The reality: Bottles arent crushed when they are recycled. They have to be melted down and sent through refining processes so.....uh what? Obviously there is absolutely no relation between the crushability of the bottle and there being 30% less plastic in the bottle
Crappy marketing strategy or not, it is pretty impressive the engineer who designed this bottle was able to reduce the amount of plastic used by 30%. That is a huge reduction of material (and hence production costs!). I think they reduced most of the plastic around the cap. If you compare new bottles to old bottles, the caps do appear to be unnecessarily large on the old bottles. Kudo's Mr. Ice mountain bottle engineer!
Tell me what you think.
