Tag: Aluminum

Last week we discussed the production and uses of aluminum, and that piece got a lot of comment traffic and made the Kos Recommended List, which I value greatly.  Some of the comments asked questions and made me decide to write a follow up piece, because some of the questions were excellent in their own right, and some of them also caused me to think a bit further about our use of this material.

Tonight we shall concentrate on a few more uses of aluminum, why it is so unique, and less environmentally damaging ways to produce it.  It turns out that there is an experimental process to refine aluminum that does not produce nearly as much carbon dioxide as the Hall-Héroult process, and might be more energy efficient as well.

There is no time like the present, so let us get started!  That is unless you have an objection.

Aluminum (or aluminium to our UK friends) is one of the most useful metals that are commonly available.  Unlike other metals such as iron, copper, and the like, aluminum has been used in large quantities only fairly recently.  Actually, alumimium is the better name, because it is in keeping with the naming of most metallic elements with the “ium” ending.  However, we shall use the US term.  Interestingly, the brilliant British chemist Sir Humphrey Davy called it aluminum, but he never produced the actual metal.  In addition, his first name for it was alumium, and folks from My Little Town who were older used that name!  That really should be the systematic name for it.

Aluminum compounds have been known for centuries, but the free metal only since around 1825 and even then in an impure form.  It was not until very late in the 19th century that aluminum was produced on a large scale, using a process that is essentially identical with the process being used even now.

It is about a week before early voting begins for a bunch of us around the country, and that means this may be one of the last times I have to convince you that, frustrated progressive or not, you better get your butt to a ballot box or a mail-in envelope this November, because it really does mater.

Now I could give you a bunch of “what ifs” to make my point, or I could remind you how we spent all summer watching oil gush into the Gulf, and how that came to be…but, instead, it’s “Even More Current Event Day”, and we’re going to visit Hungary for a extremely real-world reminder of what can go wrong when the environmental cops are considered just too much of a burden by the environmental robbers-and if today’s story doesn’t scare you to death, I don’t know what will.

It ain’t Texas, but we will surely visit a Red River Valley…and you surely won’t like what you’re gonna see.
