Again not to get too far off topic, but the subject of batteries and
environmental costs impacts a hobby so reliant on batteries...
Nickel is not non-polluting, the mining and refining/extraction of nickel
is a nasty process. Nickel is usually mined in conjunction with
copper. Phelps-Dodge (now Freeport McMoRan) has been identified as the
23rd largest corporate air polluter in the United States by the University
Having dealt with plating operations I can tell you nickel is a poison by
inhalation, ingestion, or even dermal contact. It is a known carcinogen,
teratogenic, and mutagenic. Even very small amounts of nickel can cause
death in humans. I cite "Sax - Dangerous Properties of Industrial
Materials" I have handled Nickel Acetate which can cause
near-instantaneous death in humans in doses as small as 3ppm/cubic feet in air.
Just because something is 97% recyclable by weight doesn't mean
anything. It doesn't mean it's easily recyclable, it doesn't mean the
recycling process doesn't pollute, and it doesn't mean it's cost-effective
to recycle. And it says nothing about the other 3%.
Without going into examples and getting people farther astray - just about
anything you do to "save the environment" involves robbing Peter to pay
Paul. Anybody here want to live next door to a NiMH battery plant? Or
put an elementary school next to one? I thought not...
