Hi Paul,
As always, we very much appreciate the news and updates.
On the issue of the environment, I think it would be a good idea to discuss the environmental impact of the fireworks, especially with the subject becoming increasingly talked about in recent years.
I'm not exactly sure as to how much more beneficial smokeless fireworks would be in substituting the more conventional ones altogether. One of the problems with smokeless fireworks, though, in accordance to what you've told me before, is that it can be rather difficult to produce certain effects, particularly those that involve any kind of tail. In general, too, smokeless fireworks can be rather expensive in their entirety.
I think the main argument is, according to most scientific research, the emissions that the fireworks themselves give off, such as sulfur oxides, heavy metals and carbon monoxide, in addition to smoke and dust. However, I personally would question how much it would take for fireworks to be considered significant to the environment. The thing is, much of the fireworks in use today are much less toxic than those in the past, and new possible alternatives have been and are currently researched. For example, I heard that using compressed air in substitution for gunpower can greatly reduce the amount of smoke and other associated pollutants. Similarly, I read that current studies are testing the use of nitrogen in place of gunpowder as a propellant, and the compound of nitrocellulose can be a replacement for perchlorate, helping to diminish smoke. Though most toxic chemicals have been banned from fireworks, I think barium is still allowed. However, there may be a safer method to produce the same effect, where researchers are looking into copper compounds as opposed to barium in order to produce the green color. Just of curiosity, but does anyone have a fair idea of the average total emissions discharged into the atmosphere per display (separately for sulfur oxides, carbon monoxide, etc.)?
And yes, been looking forward to the new look for this website. I guess that means that this is the last day of seeing the site like this. I find it pretty cool that the design has changed, so far, on a three-year interval.
Trav.
