Will Shortages Unplug Flat-Screen Industry?

We do everything we can to save the pandas: They're cute. But cute is not a word we'd use to describe the latest additions to the endangered list: the elements gallium, indium, hafnium, zinc, and copper. According to Peak Oil News (via Asimov's), the decline of these elements will be due to their use in flat-screen TVs, computer chips, and monitors. Time is running out quickly: Armin Reller of Germany's University of Augsberg says that gallium, which we extract from zinc and aluminum, will be gone by 2017. Zinc has more time but not by much—Reller estimates it will be extinct by 2037.

But extinct may not be the most accurate term. A commenter on Andrew Sullivan's blog points out that once we've mined the last of each element, they'll still exist, but just in products like your TV. The trick will be developing a cost-efficient recycling method.

So what does this mean for your home theater system? In a Wall Street Journal article, scientists express fear that the shortage will shelve plans for promising new technology and inventions, like a new design for solar panels.

The Tech Lounge is optimistic that advancements in recycling and the development of synthetic versions of these elements will keep flat-screen TVs glowing in our living rooms for years to come. Either that, or we'll find a gallium-free way to get our entertainment. Technology adapts to our resources. As one commenter on the Crossed Pond (via Ars Technica) put it: "We are nearly out of whale oil, yet we don't lack for indoor lighting."

Saving Zinc

One way to save zinc is to give up our emotional attachments and finally do away with the virtually worthless penny (which is made from zinc, not copper). Every time this topic comes up, people make nostalgic pleas not to get rid of it and there are campaigns to keep it around which are, generally, funded by the zinc lobby. It's also my understanding that, at least at various points in time, it costs the government more money to produce the penny than it is actually worth. It's time to discontinue it.

I may also be too late...

It's University of Augsburg by the way...

Running out of oil may not be a bad idea, we have alternatives and we also have legs and bicycles.

But the REE are somewhat more worrisome because we have not yet found any alternatives and we are making ourselves dependent on them...

Recycling metals

I am probably too late for anyone to read this but I have always wondered about recovering metals from landfills, trash heapos and junkyards. How can it more economical to convert low grade iron ore into steel than to recover the steel from junked cars lining the highwyas? Similarly, if gallium, indium, hafnium, zinc, and copper are becoming rare and therefore expensive, won't some smart group start collecting electronic trash and salvage the raw materielas?
