They move leaves off of surfaces where they are a nuisance, to a disposal area.

So does a rake or broom. It needs more manual labor to do it that way.

Some yards are large and some people are older. They can’t take and lift leaves. Many communities have it so they can be blown the street and are picked up every few days - much less labor and effort than raking into piles, picking up, bagging etc.

They’ve been banned for years in some cities. The issue is there is zero enforcement.

And the other underlying problem implied there is that electric leaf blowers are only viable for household use. They are just so completely impractical for commercial use that no one will ever use them.

So use a rake and broom, it's what I do when I clear my yard and driveway.

Edit: and for that matter we probably need to stop clearing so much yard waste. My village has crazy expensive yard waste tags (with free pickup on select weeks of the year, usually fall) and everyone agrees it's not worth it to bag grass and leaves for the better part of the year. Unsurprisingly we have tons of pollinators, healthy firefly populations, and plenty of critters that feed on all the bugs. Not to mention during spring, every one who's too lazy to manicure their lawn sees blooms with dandelion, clover, ground ivy, and columbine. My block looks like a meadow for April and May with zero effort.

Leaves can kill off whatever is growing beneath them and they can pose a safety issue in areas where people walk.

Rakes exist. It's (often but not always) slower work, but it's quieter.

But like bicycles, not every wants to use them, or has the health to use them.

Usually the crews running them are more focused on feeding their families over their own long term health. I’m still surprised when I see some crews have hearing protection.

That is exactly the kind of situation where regulations are needed. Sometimes the market can take care of things, and regulation isn't needed. But these workers don't have lots of leverage. If conditions are bad, they can't tell the boss "I have other options" and quit. So the market won't solve this case.

In all fairness, we’re not wrangling in a megacorp or small company / bad actor type.

These are usually tiny businesses where the owner is busting their ass in the hot sun alongside their crew. These are usually the smallest of small biz, and oftentimes just a young guy and a single helper.

I don’t believe we can expect lawncare prices to 4x, but this is a perfect example of targeting those who we should be supporting. If anything, structure the regulations to tier controls by size of the operation.

We absolutely should not be making the lives of a 20 year old kid trying to start something up any harder than it already is.

We don't need quieter electric leaf blowers. We need to ban the gas ones, with no grandfather clause. Not just for the noise pollution but the local air pollution. It's crazy the volume of air that can be ruined by a single gas leaf blower, far worse than modern cars, and they are inescapable in cities.

> Not just for the noise pollution but the local air pollution.

Also, leaf blowers make a lot of dust airborne, which can’t be good to inhale.

It’s not only noise and air pollution for the neighborhood, but also a matter of safety for the operators.

Is that really what people want? Leaf blowers to me are possibly the least interesting, least appealing way to use modern tech To clarify, as a research project, cool. We can probably use any new developments elsewhere. But as a tesla product, just why?

They could open source the tech and the take PR victory laps on how they are helping lower irritating noise, saving the environment, and being very cool about not trying to profit over it. That's the kind of thing that would blow up on this site. How would an electric leaf blower (or anything electric/battery/motor related) released by Tesla be any different from a flamethrower made by Boring company? At least there'…

I think enough of the ideological mob on HN that hate Elon would claim "he's just doing it to not look so evil!"

Banning air freight would be more effective in terms of reducing pollution.

I'm not talking about CO2 for global warming here, it's negligible. This is local air pollution, polluting the air I breathe in my house and on my street. The other big offender in this category is wood smoke from fireplaces, which I would also be in favor of banning, though I understand this would be extremely unpopular (I know, I love a good fire too). People don't realize that wood smoke is every bit as harmful as…

The city I'm in banned fireplaces in new houses a few decades ago. Of course, Phoenix is too hot far more than it resembles cold, and most will stay inside as much as possible for at least half the year.

"In this case 0 were read in order to rush and make a low effort joke" You should work for the NSA or the three later agency of your country, you can spot what people do possibly thousands of kilometers away! There was this one Columbo episode, one of my favorites, where the NSA wanted to hire such a guy. Sadly it was all fake. So the cynical side of me assumes you also can't spot what I'm doing at my computer, and y…

The point stands that you lied about the number of comments to aid your position, and that you didn't read even the above the fold comments.

So you weren't making a low effort comment, you were trying to start substantive discussion, but you didn't even read other comments? Sounds likely.

I guess since we're telling pointless stories about TV shows I should comment on your bright future as a HumancentiPad component.

I'm always shocked that small ICE equipment don't have catalytic converters, or any emissions reducing devices. Especially given the operator is actually holding the thing and the exhaust is just a foot or two from their face, surely the health consequences are capital letters bad .

Usually the crews running them are more focused on feeding their families over their own long term health. I’m still surprised when I see some crews have hearing protection.

I expect you don't see the hearing protection most of the time. 30 dB Ear plugs are 20 cents each and a reusable respirator is ~$25. Peanuts compared to gas and equipment.
