You ever raked an acre? Or three? Ten?
I didn't say you had to do it all on your own.
I want the stl!
So it's taking some of the air out of the stream, slowing it down, and putting it back in the stream... How does this not affect the performance?
Because that isn't how it works. I've been working on this idea in my spare time for a patent, for months. I have the CFD models to prove it. I learned ELMER and perfected the solvers and meshing process.
It grinds my gears that they stumbled upon it, get all the credit, and apparently don't know how it actually works.
Never been scooped before. But man it doesn't feel good.
Did you put your information somewhere they could find it before you got the patent? If you have authorship doesn't that mean you have grounds to sue?
I'm sure it has a marginal effect, the drag would have to reduce average velocity somewhat, but maybe it is negligible. Or maybe the overall drag is equal to an unmodified tip due to other changes such as reduced restriction.
MAKE GAS LANDSCAPING TOOLS ILLEGAL
Give away free electric tools if they trade in their gas ones. It's so bad for health to be huffing 2 stroke fumes all day every day.
Edit, I realize that this is meant for a electric leaf blower since it would do fuck all for a gas one. Doesn't change my opinion about landscaping tools tho
They already are in many communities. Enforcement is an issue.
"Electric leaf blowers are already far quieter than their gas-powered peers, but they still aren’t the kind of thing you’d like to hear first-thing on a Saturday morning. Looking to improve on the situation, a group of students from Johns Hopkins University have successfully designed a 3D printed add-on that manages to significantly reduce the noise generated by a modern electric leaf blower without compromising the amount of air it’s able to move."
First two sentences of the article.
I don't know mate, I wouldn't replace my electric tools–drills, grinders, saw... with gas ones. But these outdoors tools are a different kind of beast. I've only used an electric chainsaw and it was an absolute crap, maybe there are better ones but it was crappier than the smallest and shittiest gas chainsaws I've used, and a cord around you in that setting isn't great either.
Look again! I have a dewalt chainsaw, and I love it. I burn about 13 cords of wood each winter as it is our primary heating source. It runs and runs and runs.
I think the key is to keep the chain sharp. I use the timberline sharpener, and it gets the chain razor sharp, which means less stress on the motor and longer battery life.
The problem with electric gardening tools is they aren't that feasible for contractors.
Batteries don't last long and take a long time to charge, so it's just not an option when you're working all day. Corded means at every location, you have to figure out outlets, extension cords, fuss with tangles and obstructions, etc.
If you're doing your own lawns, yeah, you can probably get into a workflow that works for you. But a lot of people hire out for landscaping.
Fuck that shit, all the gas lawn tools should be backwards converted to run on hydrolysis-produced rocket fuel, feasibility and efficiency and safety be damned.
Gas being a better energy source than batteries in every way except for the health and environmental issues is a real bitch and why this is such a problem. Cords are a hassle and you will need a lot recharging batteries all the time, so you notice the downsides immediately and acutely. These are solvable problems though. Even running an efficient gas generator would be better for the health of landscaping contractors than being around 2 strokes all day.
Swappable batteries resolve this issue pretty well. The energy density is far from comparable, but if you're already hauling a van or trailer to the job site, then a dozen spare batteries isn't an issue.
Except being very expensive, wear out after a few years (at best), and being sensitive to being in the hot sun all day every day. All in a profession mostly worked by under privileged people where frugality is a necessity of life.
Let me help you with the correct wording: 'Power to noise'-converters. You're welcome.
