We need LiFePO4 packs, we need them at a +200% markup ($300/kwh) rather than a +900% markup ($1000/kwh), and we need them mounted in a frame based on good backpacking backpacks with a wire running along your arm to the tool.

I also assume that human operating mowing will not last long. A tiny swarm of self operating mini rovers will probably do.

That's horrific.

It isn't so much the noise that bothers me, what I've never understood about leaf blowers is what are they meant to accomplish? When I watch people use them they either blow the leaves into the street or the neighbors yard. What do they think that does? Now on the other hand, I do own a very noisy leaf vacuum. But when I've collected a bag full I can just deposit the leaves in my collection container. They are taken…

Keep in mind; in some towns a truck comes around and collects the leaves from the street with a vacuum (although I guess your town doesn't?). I have seen (predominately contractors) blow leaves into a tarp to take away on a truck though.

There is a pile of leaves so deep in the street in front of my house that it has an entire ecosystem living in it. At this point they have composted some, insects have begun to live in them and grass is growing from the pile.

To be fair, they are very good at removing debris from a front-porch. I fully support banning them, and they are heavily overused in situations when a rake works just as well, but they are superior in some cases.

I guess that makes sense, but I always personally just use the hose for that. The way I am billed, I don't really pay much for the water I use.

If three people make this, then it should say something about a.) leaf blowers and how they are liked by bystanders b.) that this might be solving the wrong problem. "you had to be the 3rd one to make it?" With people making a personal attack out of everything, I wonder: Does this make you happy? How are those people in real life? Can't they discuss things without getting personal? (Oh and I see the irony of my comme…

"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 your assertion you could see what I was doing, was fake :-(

"make a low effort joke"

You still have not understood my comment. You make no effort to understand the comment, even with my explanation. I guess this is because you don't want to understand people but get something out of attacking them.

My comment was not a joke, which was the point of my previous comment.

As someone who went all in on Ego about 3-4 years ago, let me tell you, the technology is nowhere close to capable enough for even small-time contractors yet. You would need at least 3 batteries per piece of equipment in use at one time in order to not have to spend time idle while a battery recharges ($700-$1000 upfront investment in batteries per piece). The lifespan of those batteries under constant usage would be…

I have all electric lawn equipment as well, though my mower is a Toro. No disagreements that a 13A blower connected to AC will beat the shit out of a battery-powered leaf blower, but I'm sure you do and hopefully did realize that, the math just doesn't work out. The one place the Ego does excel at is stuff like edging and string trimming, where there's not nearly as much power needed. They definitely struggle a bit o…

I have no real problem with the blower being underpowered compared to a plug-in, but for commercial use, it would be a deal breaker.

The Ego leaf blower and even the chain saw are good tools for 90% of my average home usage, and the convenience of not having to deal with cords or trying to start a small gas engine makes them worth it to me. I have not had to go to my old string trimmer once and should probably sell it. Living more north of you, I haven't dared try the snow blower. The gas blower I have struggles with some of our snows up here.

The mower on the other hand, I wanted to return after the very first mow but convinced myself that even with a poor cut the trade off was worth it. 4 years later and with batteries dying I'm considering other options (including the Toro electric, but many reviews made similar remarks to the Ego).

I just bought a battery powered lead blower from Costco. It's my first one and it's awesome! I use it all the time for things I didn't think I would. However, it is still very loud and doesn't last long enough for commercial use. One instance recently, had a few very aggressive wasps in the garage (Son is allergic). In the past I'd use some chemicals, the leaf blower got them out in seconds, it's so powerful it blew…

> I use it all the time for things I didn't think I would The very existence of a power tool, even when inert, laying (nay, waiting!, biding!) on the shelf, it shapes your mind, aspirations, disposition. Truly supernatural, a fetish, a cursed monkey paw in the curiosity shop.

Inspirational words, but I'm not giving up my power drill. Long ago my family had a brace and bit, but it's long gone, and would be awkward to use where I use the drill.

I also have one, it's called a rake.

The one I use is called "letting the leaves decompose naturally and accepting that certain areas will be mulchy". Plus a broom to keep the sidewalk clean.

Tried that, but it's not working for me on the (small) patches of grass in our garden - I guess it depends on the climate.

I don't understand this, isn't most of the noise coming from the air and not the engine in the leaf blowers?

No. Nearly all of it is the engine.

Electric doesn't have engine. It has a motor. Gas has an engine.
