There's an interesting article by Junkscience.com founder and publisher Steven J. Milloy about how breaking a compact fluerescent bulb cost a Maine woman more than $2,000 for the mercury cleanup. It's an interesting read and as ususal, Milloy (also a columnist for the hitman network, Fox News) takes an anti-environment and regulation stance. The underlying message is don't use CFLs even though it's recommended by the unlikely stable mates of environmental groups and power companies. Granted, the clean-up for the woman was a nightmare and the message is handle CFLs with as much care you would a precious glass bowl. I have switched to CFLs and will not go back no matter how specious Milloy's scare tactics. And when the bulbs wear out in 5-7 years, I will take them to the proper recycler as should everyone else. Milloy is trying to scare everyone that these bulbs and their mercury will fin their way into landfills. Indeed, some will, but the penalty for that should be stiff and recycling should become easier over time as they become more popular - an in some states, the law.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
