Miscellaneous Friday

I was temporarily unemployed for a couple of months at the end of last year, but I never considered expressing my disappointment in the same manner as this unemployed chemist. I cannot imagine this sort of thing looking good on a resume, but I’ve been wrong before.
------------------------------

Now I need to rant a bit.

Yesterday, I needed to download a software driver for a National Instruments GPIB interface card from the company’s website. It should have been a quick 50K download at most, requiring only about a minute of my “valuable” time. Annoyingly, the entire process took 45 minutes -- time that could have been better spent searching the Web for more antics by unemployed chemists. First, the website required me to register before downloading the file. Swine! I already paid for the hardware! Forcing me to register just to download the accompanying software is sooooooo last millennium. Check out your competitors’ web sites. And what’s with all the “required” questions? I can understand asking for my email address so I can be spammed, but do you really need the name of my firstborn?

After being granted access to the download page, I discovered the “driver” file was over 108MB. WTF??? Are they sending an operating system along with the driver? Please: make non-essential utilities a separate download. If I had been downloading this from home, it would have not been that big a deal, but my company’s firewall insisted on scanning the entire 108MB file for porn and viruses, and the scanner is not very fast.

Anyway, I feel better now.

Our governor here in Michigan has been desperately trying to make the state less reliant on the automotive industry. For the past few years, she’s been pushing to make Michigan the biodiesel capital of the world. Last year, she was promoting solar cell technology, partly since we have several companies (Dow Corning, for example) which are in the photovoltaic arena. And yesterday, she announced a program designed to (hopefully) make Michigan the nation’s leader in the manufacturing of lithium ion batteries for electric and hybrid cars. $300M in tax credits, among other things, with an eye on grabbing a piece of the $2 billion earmarked by the federal government for advanced battery projects. Basically, she want s Michigan to be the "alternative energy" state -- not to be confused with the "alternative lifestyle" state. According to Governor Granholm, “We are going from rust to green.” Will this work? I don’t know, but all three areas have need of inorganic chemists and that’s definitely okay by me. All the chemistry based jobs listed around here are pharmaceutical based.

Biodiesel, the new weight loss program

I’m not quite sure why, but the vast majority of chemistry blogs I’ve discovered so far are being written by organic chemists. Perhaps they have too much time on their hands or maybe Inorganic chemists have nothing to say. In any case, since I am an Inorganic chemist, you will find most of my posts will deal with Inorganic chemistry. This post, however, is an exception.

Biodiesel has been in the news lately, billed both as a greener fuel and as a way of lessening our dependence on foreign oil. Unlike biofuel, which is a general catch-all term (ethanol, methanol, etc.), biodiesel is a very specific set of compounds. Biodiesel fuel is produced by the transesterification of various (usually vegetable) oils, typically with methanol.


After removing the glycerol, unreacted fatty acid, and left-over alcohol, the methyl ester is ready for use in a diesel engine, although some engine modification may be necessary for optimal operation. For practical reasons, pure biodiesel is rarely used in vehicles. Usually it is mixed with diesel fuel, with the most common blend being a 20% biodiesel – 80% diesel mixture, referred to as B20. Despite all the hype, not all is perfect in biodiesel land. Fail to remove some of the reaction byproducts and you’ll eventually clog your fuel lines. And depending upon the choice of crop grown and manufacturing methods used to generate the methyl esters, the carbon footprint of biodiesel may not be all that much better than fossil fuels. Anyway, our governor here in Michigan has declared that biodiesel fuel is our future and who am I to argue?

Why am I talking about biodiesel now? The Daily Mail has an article describing a biodiesel fueled boat to be used in an attempt to set a new world speed record. Apparently, the boat’s skipper underwent liposuction to remove some of his fat for conversion into biodiesel in order to help fuel his boat. Is this guy green or what?
