I always wondered about how bad those little mercury cells could be for the
environment. I mean they're so tiny, and they last for 5, 10 years or more
- at least in Spotmatics.
Don't get me wrong, I'm very concerned about environmental issues; I don't
even own a car! But with all the crap that factories and cars spew into
the air, and all the crap that factories and sewage systems spew into the
water and ground, it always seemed to me that for the US to ban teeny tiny
mercury cells is like killing a mosquito with a sledge hammer.
Problem with the Zinc Air batteries (so I've heard), is that they don't
last very long. Maybe 6 months or a year (someone with experience, please
correct me if I'm wrong). So, which is harder on the environment? A
battery that lasts 10 years, or one that last 1/10th or 1/20th of that, and
therefore causes 10 to 20 times more volume of waste to dispose of?
Just curious.
regards,
frank
