One of the most underappreciated features of a regular lawnmower is that the spinning blades isn't just a big knife spinning around. It is also a propeller sucking the grass up into it, exactly to combat the problem with the lawnmower chassis pushing the grass down under the spinning blades.
So if he adds a suction device at the top, he might get a better cut?
@@WastedDad Yup.
@@WastedDad I thought he was making the top bigger to add some suction to the top. Big ol' Box fan for something to shoot that grass confetti after it's been freed from it's earthly ties.
@@WastedDad The major problem with that is you're basically fanning the flames though, so if any spark gets started you're in BIG trouble
*gets sucked in by the reel mower*
hang on...
sigh... out with the "allen scythe", commonly known as the "dog trimmer"...
Ending the video with a simple single laser setup that works for the purpose intended after seeing Allen's all out brute force megawatts of lasers attempt to make "lawn mower but blade = laser" was brilliant. Never stop being you Allen
having already seen the simple one back when it first came out (rctestflight's rotating laser), this was a romp with that in the back of my mind
i saw that other video when it came out and i was like "waith a second, i saw someone do this before! I wonder how the allen solution will work out 🤣🤣"
@error.418 you mean the lazer fly swatter?
6*30W =/= several Megawatts
I have a picture of a ghost on a tv.
"Something bad and obvious happened," The grass catches on fire.
Yeah, I've been waiting for that.
I'm surprised it took that long
THAT GRASS HAS BEEN COOKED
I DID IT I FULFILLED THE PROPHECY
Yeah, when he mentioned California mower restrictions and lasers, I immediately thought, "And they'd also ban laser mowers as a fire hazard if they'd thought anyone would attempt them."
Honestly I clicked on the video saying to myself "there's no way that doesn't just set the gras on fire, right?" 😂
Alan holding a laser pointed at a single blade of grass and watching it slowly burn through in a couple seconds: "This cuts better than a knife [it does not], lets put it in a spinning contraption so the laser only touches each blade for a fraction of a second....oh no it doesn't work."
The tall answer isn’t to go futuristic, it’s to go back to the past. A good scythe (there is a very wide range in quality) is actually a better replacement than you’d think, with a significantly longer lifetime than most things you buy today.
don't forget the black hooded cloak. can't truly wield a scythe without one
Not even necessary to go back so far. A regular push cylinder mower will allow a very nice and even lawn cut.
Y'all don't mow large properties or for a living. Do y'all? Your suggestions are ludicrous. California policies are a disgrace and the reason people are leaving that state
Ok so laser scythe then?
Yeah we ain't amish, that's some hard work
Who keeps letting this man have dangerous lasers? This is how we get supervillains people
I don't know but I sure don't want to stop him
It's also how we get superheroes.
How bad could a laser supervillain be really, or at least this guy as a laser supervillain
Allen Pan is Laser Man
Let him cook.
(with LASERs)
I think the stationary lawnmower idea has merit.
What you need to do is set up a grid across the perimeter of your entire lawn. That way you can just turn it on and let it run instead of moving around a small grid for hours.
Bonus points because you can use it to maim trespassers.
I can see where Allen's head was at though, his lasers are "contained"
Reminds me of the laser security system from Over The Hedge
Man, the lawsuit from that booby trap would bankrupt Canada.
gotta level your lawn or the setup gets real wacky real fast
I think Allen should try making an autonomous scythe machine. A Scythe Roomba, if you will. I bet it could be more effective than a mower.
LAZER RAZOR

Yo
LAZER RAZOR

9:41 I love how the guy with the exposed toes/heel is the one stomping out the fire hahaha!
I love how all the engineering TH-camrs shout eachother out, such a great community!
Are they actually engineers though? Because both my physics teacher in high school and when I went for engineering school both said on the first day, "follow Occam's Razor" or the more blunt way, "Keep it simple, stupid!" This video did the opposite. There's a reason why we still use physical blades to cut a lot of things. They are the fastest more effective way to cut than laser. Granted, we do use lasers and plasma gas to cut metal but often seeing the process in person is much slower than using a mower.
@@WJCTechyman Their purposes are different. The things they engineer are supposed to be eye-catching, over the top, and just generally fun. The process they follow and the obstacles they overcome are engineering staples and just because their projects don't match practical industry standards doesn't mean they aren't engineers.
Working with a 30-40W laser and knowing the power those things have, watching this almost gave me a brain aneurysm.
so fukking unsafe and irresponsible
Yep, I work in the optics & photonics industry and we take laser safety VERY seriously (as you should when they can bore a hole in your head) and this stressed me out SO much
Need a 20,000 watt
I run a 2500 watt so this just reminds me of a toy lol
@@soflossy6447 That's the additional danger of high-power lasers: stuff that could easily fry your eyes to a cinder suddenly doesn't seem that serious hahaha
I think the solution here is to set up a bunch of pop-out lasers that mow your lawn, the same way that you'd lay out an automatic sprinkler system. I think that would be a terrific idea, although dogs or delivery people might not agree if they happen to be walking on the lawn at the wrong time.
Or when you're done with the lawn you casually start cutting the fence
*(flashbacks of the Resident Evil laser room scene)*
Or something goes wrong and u blinded a bystander or something. Lawsuit waiting to happen
Just engineer grass seeds that yield programmable grass length. Probably already exist just a matter of time for rules and regulations.
@@rezlongboards3918 Maybe play emo music until the grass cuts itself
it's so cool you gave the shoutout to Rctestflight, he's got a ton of cool projects, including a solar powered boat he rode around in Seattle waters
I was also just thinking about how that would be a better solution it probably still wouldn't work for a whole lawn but would be sick if you had a laser to cut your lawn. talk about flat lawns.
Rather funnily, Daniel was actually at Open Sauce this year so there's a very high chance that Allen met Daniel and then still shouted out his channel as if he stumbled across it lol
i love that channel. collab soon!
You won't be mowing yards in the year 3000, we will all be living underwater. And your great great great granddaughter, is doing fine.

You couldn't pay me to take this level of risk with lasers lol. I'd be too careless for a split second and then never be able to see again.
it’s honestly pretty crazy how many hours or work and time was put into the video, countless hours behind the scenes, programming, and creating to make this into a 10 minute video. it’s honestly amazing.
Can't wait to see Styro Pyro's upgraded reply to this video 😂
Ya shoulda shipped styro down and he would have allan workin in no time.

A Lazer that removed all your grass
@@burgundyknight6826same thing they use for crop circles 🌀😋
You need one of those pulsed laser rust removers. You can use a wide beam and they are so powerful it would instantly cut through a patch of grass in a fraction of a second
He could borrow Kevin's.
@@jangschoen1019 yep! That's what made me think of it
That is what I was thinking the whole video. Only problem then is half the mower is batteries and it only works for 10 seconds, lol.
video title will either be "blinding an entire city in less than 5 seconds" or "accidentally blinding myself and my whole family for wacky content lol" depending on how far he makes it into the experiment.
when removing rust, the surface is dry. the materials are good at absorbing energy and heating up.
water has to absorb latent heat, and it takes a LOT of energy to take it from liquid to gas... and until its removed, you are stuck at 100C.
and its only being heated by the absorption of the "solid" matter around it, conducting heat to it. the laser cant heat the water itself, directly.
i love when people publish "failed" experiments. not only does it drive discourse towards a possible solution but also teaches so much along the way. thanks for this video. it made my day.
Last year, we found out all the reasons nobody's making laser flyswatters, this year we're finding out why nobody's making laser lawn mowers.

The world: you can direct laser beams with mirrors!
Allen: NOOOO SPIN THE LASERS!
shouldve had them in like a thing with several lasers and also mirrors to expand the area and then have that entire thing spin, the whole grid would be going around the grass it would probably work incredibly well compared to not moving
insertion and reflection losses.
100W laser, 99% reflective mirror... the mirror is absorbing 1W.
any dirt ... 10W...
the lenses... absorbing power...
every surface that beam has to bounce off of, or transmit through, is absorbing a certain portion of the energy, and if they arent made to deal with the energy, to radiate it away somehow, they quickly fail.
and the power falls rapidly, compounding with the number of surfaces in the path... a single lens will outperform a triple lens but the single lens will have a harder time focussing...
its all a trade-off, a set of compromises....
Spin the mirror instead?
@@paradiselost9946
Front surface mirrors using Gold as the reflective material are probably not as hard to make as you think.
Just get a flat and polished piece of aluminum for one electrode of an electroplating cell, some shredded gold foil as the other electrode, get the polarity right, and pick the right electrode that facilitates motion of gold ions from the foil electrode to the polished aluminum electrode and that should gold plate the polished aluminum piece.
Gold doesn't oxidize readily in clear air, and when Aluminum oxidizes, it creates a strongly adhered layer of Sapphire, so you can even skip the gold part if you can make your laser beam's wavelength bounce off a layer of Sapphire.
And with the right grit, and the right lapping plate, you can polish sapphire to an incredibly reflective surface.
Or you know, this kind of thing might be cheaply available online off like AliBaba or Ebay or Amazon, I haven't searched for it.
But if you do this, you can probably cut that 1% loss on the clean mirror down to like 0.01%.
I actually brought a ryobi battery mower three years ago and happily glad to say I am never buying an ice mower again. So simple and easy to use, super powerful as well.
Grass is really hard to burn. I have a giant pile of grass and if you throw some on red hot coals it will barely burn, and put out the fire. The other problem with a laser mower is that you would likely cause a grass fire if it works. Grass that is standing up and dry seems to burn very easily. Crab grass if what I got. I got about 500 pounds of cut Crab Grass and herbs and it won't burn. It would probably take 20 gallons of gas to burn it.

Bro always finds the most scuffed ways to do things in the most genius way possible I love this lmao
even though the project wasn't perfect I still think it was an awesome idea and a fun build. This is definitely a year 3000 lawn mower and you did it first! Good shit boys.
One of the big issues is that each laser is spending the vast majority of its time doing nothing and not burning anything. My opinion, mirrors are your best friend here. Even one laser at full mirror efficiency would be extremely effective. But you could use several lasers at very very slightly different elevations, all utilizing the same round mirror array, which would cut grass ridiculously efficiently and will likely come close to a real mower. Would love to see a version 2
That poor grass experienced war crimes.

r/youngpeopleyoutube
I was one college project away from attempting precisely this. Thank you for "wasting" $$$$ on lasers so I didn't have to. You are a real hero.
I have a solution. Paint your grass black, and it will cut, simple right?
Why is no one talkin about how California is banning gas mowers that cost $100-$250 for terrible products that are over $700?
They also have/are getting rid of gas stoves, cars, gas weedwackers and anything else gas-powered here in Cali 😡
I work with industrial lazers. We used a "multifaceted mirror" (think of an octagon with mirrors on the sides) to effectively swipe a laser across surfaces. Now we just use a prism to split the beem
This is what I was thinking. Those scanners at supermarket checkouts use a single laser and a concave mirror spinning on a motor. If you had 4 of those 30w lasers focusing into a spinning mirror or a prism that could spread it out a bit then it would be much more effective. Even having the lasers created something like a bridge across the front of mower instead of the centre.
@@xenibyte5898 It would still be slow, look at laser cutters. The same goes for a plasma cutter as well. It's very slow. Also what you reference here has been obsolete in xerographic printers for a long time. They now use an array of individual focused LEDs. To both you and @jonahkolell, please refer to Occam's Razor, also known as the KISS rule, something that engineers learn early on in science as well as engineering, unless it's Germany, then, throw it out the window to put complex features into everything they make.
why is no one talking about how California banned regular lawnmowers?
California unfortunately banned all new small engines rated 25 horsepower or less. This includes two stroke and 4 stroke engines. This new law was put into effect as of 2024 but was signed into effect about 2020ish (thanks Newsome).
People can still buy gas powered equipment if it's old stock or technically if the engine was made 2023 or older. But most stores are too scared to restock new old stuff. Or if you know where to look and buy you still can get new stuff.
Also if you've owned gas powered equipment prior to the ban you are safe to still own and operate it. It's just the new stuff.
California keeps voting in Democrats. They can get what they vote for. ID10Ts, none-the-less.
Ngl it sounds dumb asf 😂
People aren't surprised by California banning stuff anymore.

I love the concept, as well as the tinkering that this dude is doing. That's how engineers and inventors get started.
That said, thankfully for you Californians a Lowe's electric lawn mower (I believe the brand is called kobalt) is somewhere in the 300.00 range. If you add a couple of extra batteries, that puts it closer to the $500 range but, I recommend it if you're going to go electric because then you just swap out the batteries when your lawn mower quits halfway through the job.
So far that's worked very well for me.
By the way, it wasn't my intention to go electric, I just did it because I wanted the batteries for an extended chainsaw.
I'm pretty sure the reason it wasn't cutting is the high moisture content of the grass being very effective at dissipating the heat from the laser, it would probably work better on a drier medium.
That would cause fires though, unless cut and then moistened. I would be a fan of that, until the sprinkler is out without warning.
not just dissipating, but absorbing... and it takes far more energy to evaporate that water, turn it to a gas, than it does to merely heat it. and until it IS dry, you arent going to exceed 100C...
1:17 I feel like a rotating mirror would be a better solution than turning the entire laser emitter. But also, a mower blade lifts the grass to perk it up while cutting but also expel it from the cutting area - assuming you have a discharge of some type. Potentially if you have a combiner reflector to focus all lasers into a single beam, it could cut the grass much more quickly
I love how all the youtubers who like to play with lasers live in the state that burns down every couple of months
thank you california for making us reinvent the lawn mower with even less efficient means lol

Good on you for finding a more cost-effective mower then electric. You could also move.... or converting your lawn into a giant stone driveway. Its nice to turn your entire property into vehicle storage.
Thick corded Weedeater mower works good enough for me. I never worry about some random rock neighborhood kids tossed into high grass and I can mow down more forested areas without worrying sbout sticks.
Allen, I’m not sure if you’ll see this but I just wanted to say that I absolutely LOVE these fun videos. I love to see these absolutely crazy ideas come to life, even if they don’t work out how you hoped from the beginning. I hope you continue to have fun reimagining these mundane household items.
9:23 "really good" lol
Use a much higher powered pulse laser. This vaporizes rather than heats. You will still need to suck up the cuttings so they don't waste energy getting cut even more.

They're louder and worse than electrics, hell I think corded electrics are even cheaper now on the low end. Considering they're basically a cieling fan on a cart.
Old maga types still don’t understand that gas engines are trash.
@@PilkScientist They really aren’t better, you need multiple batteries just mow a large lawn, they cost more, self maintenance is near non-existent, and they’re not inefficient. The only benefit is that they are quieter but other than that they are worse when compared.

@8:20 if you want to see if this is a revolution or not
Weak attention span
1:34 y not just put the lasers on the outside and point them at a spinning mirror like how every modern radar works?
Lawn mowers have 2 specific elements to it. 1st is that it cuts the grass but the other part is the blades spinning create a vacuum effect to pull the grass straight. Try adding a leaf blower to suck the air upwards. it might also catch the grass on fire lol
Agreed not only could a fan of some sort help raise the grass similar to the blade of a standard lawn mower but it could also assist in cooling the lasers and assist with the discharge of clippings. The trick would be keeping the grass still enough to be cut. Maybe back to the drawing board. 😊
Well the title seems accurate. At this pace, You'll be done mowing the lawn by 3000.
The last commenter is exactly right. One laser set to pulse, with mirrors around it and a fan would work. Of course could just use a hot wire.
but a hot wire isn’t fun lmao
Just watched the whole video within 30 seconds. Love it. Keep it up man.
You should install a vacuum on the top the lawn-mower opening, which would both clear the cut grass out of the way of the lasers, and also straighten the uncut blades so they are easier to cut.

Around 8:23 mark, fingers within inches of the laser grid .... yikes. 30W is more than enough to make you sorry!
SOURCE: Me, having VERY briefly taken ~45W to a thumb once. Like touching an old school electric cig lighter. (Why do I do these things???)
The water content in the grass is why it won't cut. An air balloon will pop immediately over a flame, but try popping a water balloon over flame. The water is absorbing all the heat energy.
This is why hair trimmers have a comb directing and extending the hair right befroe the blade. You could also alternatively have a shop vac pulling it up and freeing the cut grass from the way right above the line.
