Technology may not be able to save us after all, especially if we run out of the stuff used to create it.

$this->bbcode_second_pass_quote('', '[')b]Shortage of Rare Earth Elements Could Thwart Innovation by Jeremy Hsu, TechNewsDaily Contributor
LiveScience.com Jeremy Hsu, technewsdaily Contributor, livescience.com:
Silicon may represent one of Earth's more common elements, but it transformed Silicon Valley into a high-tech corridor and helped usher the world into the Information Age.
Now rare earth elements with exotic names such as europium and tantalum hold the key to hybrid cars, wind turbines and crystal-clear TV displays - that is, if a looming supply shortage doesn't stop innovation in its tracks. …

Good point, they don't call them rare earth metals for nothing. Here is a neat site, you can just click and order some. With pictures of what they look like.

$this->bbcode_second_pass_quote('', 'T')he rare earth elements are not really rare. At one time these materials were considered to be rare because they occur in nature in very low concentrations and are difficult to separate one from the others. It turns out that the rare earth elements are actually widely scattered throughout the earths crust and so are not rare at all. Even the least common rare earths are more abundant than the platinum-group metals and gold. However few concentrated, exploitable ore deposits have been found so far.

IMO this is just plain silly. Rare earths are called such because THEY ARE RARE, therefore anyone who is surprised that they are rare needs some basic English comprehension lessons.
Making a Hybrid battery using Lanthanum is all well and good, but that does not mean OTHER types of batteries are not an option if there is a Lanthanum shortage. The same argument can be made for the other choices as well, while a rare earth element may be the best case scenario for your need it is NOT the only option.

$this->bbcode_second_pass_quote('Alfred Tennyson', 'W')e are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
