[Phys-l] Fwd: [PHYSHARE] Can't win for losing - NF3



Fwd'd by bc

Seems a very stable non-biodegradable gas.

Attention-worthy, but note it is at present only one scientist's take on the dangers of NF3 (nitrogen trifluoride).

Of course, both GB and the US are poised to obsolete pre-digital over-the-air TVs and create a huge demand for LCD replacements.

Abbreviated quote follows:

'HD TV gas' 17,000 times worse for planet than CO2, claims boffin

LCD TVs, praised as being greener than old-style tellies because they consume much less power, may actually be speeding climate change... atmospheric quantities of the gas Nitrogen Trifluoride (NF3) are booming. ... The chemical is used in the production of flat-panel displays which, in turn, are used to make today's TV screens....

NF3 is 17,200 times better at trapping heat in the atmosphere over a hundred-year period than is carbon dioxide, the best known greenhouse gas....
