Just to be clear, the noise and air pollution that a switch to drone shows away from fireworks shows would save, would be incredibly significant. I don’t think the cost makes it viable yet, but it’s something to aim for.

7,500 reusable/repairable drones in this show vs more than 12,000 single use fireworks in London’s last New Year’s show alone.
I fully agree that fireworks still have their place, but I think the suggestion that they’re in any way comparable to drones from an environmental standpoint is way off base.
I’d like to see a better analysis, that’s all. I don’t know either way, and I’d bet that the co2 of the drone show is orders of magnitude lower than fireworks, for example. But as with lots of emerging technologies, it’s hard to make direct comparisons - is the lithium going to be recycled at end of life, did it come from “good” mines, how much of the plastic will end up in landfill and how much is pla/plant-based, and how does all this compare to the cardboard and explosive in the fireworks. Also, do the electronics contain conflict minerals, and are they recyclable, and what’s the expected life of the drones? How do the chemicals for colour in the fireworks affect their pollution, and how are they produced? Having recently seen an fairly damming look at Formula E (run on generators that are flown from England to wherever the races are, that kind of thing), I’m just intrigued to know more about how the sausage is made, if you see what I mean. It’s in our interest to ask this kind of thing, in the same way that it would have paid to ask more questions about how single-use plastics would be disposed of, rather than just trusting that them using less trees in their construction was worth it. These things never have a simple answer, and I’d like to know as much as possible
This is the exact same argument that I see used against EVs almost daily, while the people making these calls for “better analysis” ignore the dodgy mining practices and literal wars that are the result of oil extraction. But let’s go back to fireworks. I spent all of 30 seconds Googling and found this. I’m sure it’s far from an exhaustive list of firework ingredients but it’s a decent start. Highlights include:
Sulfur - extracted from oil and natural gas.
Aluminum - 28% of US aluminum comes from recycled sources, which is great, but any that goes into fireworks is then lost forever. The rest of it comes from mines in Canada and Jamaica.
Iron and copper - Mined domestically and both are recyclable but gone forever once they’re exploded.
Strontium - Mined in Mexico.
Barium - Mined in China.
Sodium - Mined in Chile and Peru.
How come you’re not asking for a better analysis of the mining practices for the ores extracted in Jamaica, Mexico, China, Chile, and Peru? How much of anything that makes up your average firework, including cardboard and plastic, is recycled at the end of that firework’s life? How many fireworks are reusable even once let alone tens or even hundreds of times? Much like with oil burning cars, these things are ignored because they’ve been around for a long time and it’s normalised. Meanwhile emerging technologies, while demonstrably cleaner/better in pretty much every metric, are held to impossible standards that the old tech gets a free pass on.
No, we don’t recycle much lithium yet but it’s a new technology and battery recycling plants are springing up all over the place all the time, and these same plants often deal in the various other electronic materials that you cited. How much used petroleum is recycled each year? How many fireworks?
I don’t want to argue and I should probably just delete this rather than posting it, having said my piece to myself, but perhaps I’m my own worst enemy…
Brother, I think you’ve read more into what I wrote than I intended. We’re on the same page, I drive an EV and work in solar… I’m not in any way saying that I think drones are a worse option overall, when I said I’d like to see a better comparison, I mean exactly that. I’d like to see it, because I’d find it interesting. I never see well-thought-out comparisons of this kind of thing. While clearly better by many metrics (and arguably the more important ones - water and air pollution, plastic particles, etc), I’d still like to see a comparison of total embodied energy, and whole-life environmental impact. I’m sure it would still come out in the drones’ favour, but just assuming that is no good reason not to actually see the data.
I think I’m a little jaded where it comes to battery-powered stuff on a small scale. I see so, so many bits of battery-powered crap going to waste because it’s cheaply made and essentially unrepairable - from vapes to scooters to toy drones, even little speakers and vacuums. I see a lot of stuff touted as “eco” that actually ends up being one use, or close to it, so I assumed (probably wrongly) that these drones would end up being used a handful of times before being junk.
EVs are a different kettle of fish, even though they are pretty complex and full of electronics, there’s still a decent financial impetus to recycle them properly, and the batteries and components can be reused - my home is powered by second-hand EV batteries and solar.
In essence, I’d like to see more comparative analysis of anything like this. The earlier we do it, the better we can choose which technologies to use going forward. A really good example of what I mean is plastic bags - this video highlights why it’s so hard to work out what the best option is. Not because I’m looking for a way to keep using a harmful technology, just because the answers are complex, and without a clear “best option”.
