EarthFirst Blog Week in Review March 17 - 21
March 24, 2008
Well we are just shooting up faster than Bio-tech corn here at EarthFirst! We’ve added a bunch of hot new writers (Professor Scott Herring and token Swede Anders Porter) and features (Mr. Cranky Green!) and are getting more hits than Tony Soprano during tax season. We’ve covered Green Fire Works, a terrifying robotic pack mule, and celebrated World Water Day like eco-rockstars! We also have two EarthFirst birthdays coming up under the Aries symbol; our wide-eyed editorial intern and writer Caroline turns 23 on the 28th and our fearless leader Jordan will rock out on the 27th when he turns…old. Yippee-Ki-Yay!

No More Eco-Guilt on July 4th- Chemists Developing Green Fireworks
March 18, 2008

This is spectacular news- scientists are developing green fireworks. I love a big night of fireworks as much as the next guy, but the fact that the smoke produced by the show was chock full of toxic chemicals and gases always bothered me. Conventional fireworks leave behind a cloud of lead, barium, chromium, chlorates, dioxins, CO2, nitrogen, sulphur oxides, as well as smoke and particular matter.
Conventional fireworks draw their energy from the oxidation of carbon. Clean fireworks, on the other hand, would get energy from the high temperatures that occur with the formation of nitrogen-rich compounds. Some possible compounds could be tetrazoles and tetrazines, which are made of four nitrogen atoms and either one or two carbon atoms, respectively.
To produce different colors, chemists could use aminotetrazole salts with specific non-toxic metals. For example, lithium, sodium, potassium, rubidium and cesium result in red, orange, violet, purple, and pink flames, respectively.
Somewhat ironically, the most difficult color to produce with “green” fireworks is green. The researchers are looking into green-burning salts based on copper compounds.
