Yes, I do. Here you go champ.
Objectively, so you have some data to back it up? Do you have the comparative carbon footprint of those shows?

No you don’t, that’s for fireworks, now we need the impact of drone shows to answer the problem. Would you have it?

My brother in christ, drones are all over that paper. Have you read an academic paper before? Do you know how to follow sources in papers? Tell you what, you go find some sources of your own and we can compare. Sitting back and saying “nuh uh” ain’t gonna do it. Put up or shut up.

Ok, I got time to read it. Drones are only mentioned in one paragraph of the conclusion. Here it is:
‘Eco-friendly’ fireworks, which do not use perchlorate and have lower levels of heavy metals, do exist (Fan et al. 2021); the problem lies in their higher cost of manufac- turing (Palaneeswari and Muthulakshmi 2012). The future of ‘firework’ displays may lie in the use of drones or unmanned aerial vehicles. Drones and visible-wavelength lasers for light shows have the benefit of being reusable, have no emissions, and are quiet (Daukantas 2010; Zerlenga et al. 2021). Drones come with their own issues for wildlife, however, usually flying at low altitudes where there are most likely to come into contact with wildlife; a review indicated that many taxa react negatively to the presence of a drone (Rebolo-Ifrán et al. 2019). Even so, drone light shows are less likely to disturb animals, wild or domestic, with noise, nor do they deposit large amounts of pollutants.
The use of drones is an opening hypothesis, not the subject of the study. Impact of drones is not qualified, it is hypothesized to be lower. The linked papers that I have also checked also don’t quantisize the impact but similarly mention it as a potential eco-friendly alternative.
Would you have a different reading of this article?

My mistake, I read too fast, let me read it and get back to you.
Grayox@lemmy.ml 2 months ago
Lmao are you being serious or do you lack basic logic, drones are reusable and put off zero emissions, fireworks are not reusable and put off a shit ton of emissions.
oce@jlai.lu 2 months ago
Zero emission at use, not at fabrication, probably not when recharging and not as electronic waste at the end. Yes, I am being serious, considering only emission during usage is a very limited view of what carbon footprint is. A view that is often used by companies for green washing. Do you also believe electric cars are zero emissions? Considering full life, knowing which one emits more is not trivial.

And ignores the typical 20%-40% of energy lost to heat during charging for most batteries.
Grayox@lemmy.ml 2 months ago
There are emissions in the production of fireworks as well. Drones can be recycled at the end of their life cycle, fireworks cannot be recycled. EVs ARE zero emission just like drones, they offset the emissions put out during their production after around 40k miles and are extremely energy efficient unlike combustible engines. An EV running on a coal fired electric grid puts off less emissions than a prius.
oce@jlai.lu 2 months ago
Absolutely, fireworks also have emission in their while life cycle, so let’s get the data and compare. EVs are not zero emission and offsetting is not zeroing emission, it’s just compensation, pollution is still being produced and if everyone does that we will not reduce it. In fact EVs sometimes have higher emissions than thermic card at fabrication, but it has been demonstrated that they emit less during their full lifecycle.

Please stop with such language, we had enough of it on every mainstream platform.
I genuinely call for civility here.
As per the substance, as already mentioned, the production and later disposal of drones does have ecological footprint that is very much not negligible.
Grayox@lemmy.ml 2 months ago
How are fireworks better then?
oce@jlai.lu 2 months ago
I am not saying they are better. I am questioning if they are. Please don’t mistake my question as veiled disagreement, I am not a Xitter user. Someone claimed an objective opinion, and that supposed to have data and a study to back it, but there likely isn’t any yet. I am open to the possibility, I just want to make sure it is actually more ecological. It is objectively demonstrated for electric cars vs thermic cars, for fireworks vs drone show, it probably isn’t yet.
Allero@lemmy.today 2 months ago
I wasn’t the one to claim that, and neither was the person who opposed you, from all I could see.
There’s just not enough research/calculation done on drones vs. fireworks, and a lot has to be taken into consideration. How often are the drones used? Are they recycled at the end of life? Which materials are used in their production, and what is their source of energy? etc. etc.
The advantage of fireworks is that they are very simple and use little materials to produce, most of which are safe (but some are not great).
Drones, on the other hand, require a lot of lithium and cadmium, as well as other basic resources like metal/plastic, silicon etc., and some parts of their manufacturing involve high-end facilities that require a lot of resources to maintain correct conditions. All of this leads to high footprint of their manufacturing, and if you use such drone just a few times for some large-scale swarms and then forget about it for a while, this will get way less ecological than fireworks.
Don’t get me wrong, the technology is good and drones can absolutely be a superior option. But this heavily depends on how they’re used.

B-b-but they use batteries!!! Electricity bad! D:
/s
Allero@lemmy.today 2 months ago
Batteries = genuinely bad.
Also, energy doesn’t always come from clean sources, and even then, they do have footprint of their own.
BearOfaTime@lemm.ee 2 months ago
Charging batteries typically loses 20%-40% of energy to heat.

Lol so?
