So, what is the concentration of mercury vapor in ten cubic feet of air near where a single CFL device has been broken ? and where in the lamps does this 3 micrograms reside in the lamp, and why would it be in a vapor form at normal room temperatures? My observation of the broken lamps that I have seen is that there are quite large chunks and a few small slivers. I know that the slivers can be nasty and sharp, but clearly most of the white stuff is still in the glass. So where does all of this huge cloud of mercury vapor come from?
OF course it is best to avoid breaking the lamps, but this writeup seems to be intent on arousing hysteria and fomenting panic. If we went back to using candels for light the big hazard would be setting fires, which are probably a lot more dangerous.
I am not advocating stupidity, and I would never allow children to play with broken lights, but the whole tone of the article seems inappropriate for an intellectual publication such as Design News.
Interesting story, Todd. I would guess the packing that absorbs mercury costs quite a bit more than traditional packaging. I wonder whether this will affect its use. Unless there is a government mandate, it could be this packaging will not be widely utilized.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
