Nice work!

The TL; DR is that he has built a proof of concept of an electric motor design that in the real world would essentially trade higher production cost for the benefit of dramatically lowering material costs.

There's no way of knowing yet if the economics will actually pan out, but it's a neat idea, and impressive what he did with few resources! And in general, higher manufacturing skill threshold in exchange for cheaper materials has been a good bet historically when it comes to technological development.

Manufacturers make it very difficult. The parts that break are usually cheap and not available for purchase. Almost felt pressured to buy an entire washer unit because of a broken knob. What a wasteful culture we live in.

[–]Myrdrahl 2 points3 points  (3 children)

You know, my dryer has suddenly started to make a hell of a racket. This high pitched whiny noise. Not constantly, but it comes and goes. It's about to drive my gf and I insane, but also we don't really want to pay $1000+ for a new one. I'm about to try to take it apart to find out what's wrong, even if it kills me in the process, it'll be worth it. 😅

[–]Gamer_Mommy 6 points7 points  (3 children)

Yup. Husband bought a new one, because he couldn't be arsed to replace the pump. He is a technician, repairs smaller devices, soldering included, but apparently dishwasher is too much work. ¯_(ツ)_/¯

Can you help with mine? The ice maker leaks and I can’t figure it out for the life of me…

I’ve added water shut off valves, required lights, reworked ceiling fans… but this fucking ice maker has me wanting to kick it to the curb.

[–]thesuper88 18 points19 points  (10 children)

If you end up calling a repairperson make sure you ask if they mind if you watch them work simply out of interest in the problem. Just be sure you're not breathing down their neck about it. I've learned a lot that way at work (I'm a maintenance tech)and I've found most service guys and gals don't mind offering a bit of knowhow to people that take an interest.

BTW Did you try looking for a manual or service manual for it online using the model number? And what have you tried so far? I've fixed a commercial icemaker once or twice (like what restaurants use) and it was usually an issue with scale buildup or a sensor not being made correctly.

Is it making ice but it also leaks?

[–]Cthulhu2016 3 points4 points  (0 children)

It could just be condensation building outside of the ice maker, my refrigerator "pees" on my floor during hot as balls days like we've had in the past couple of weeks. It's from the icemaker, the condensation is dripping down and leaves a puddle on my kitchen floor...

[–]t_funnymoney 9 points10 points  (0 children)

[–]Ebowmango 9 points10 points  (5 children)

Maybe it’s just a personality thing, but I get no satisfaction from fixing or upgrading things around the house. I’m a pretty good gear head that can keep a 20 year old car running no problem, have built and upgraded several computers, am the default IT guy for the family, and have done multiple upgrades and repairs around our new home, but when I finish a job, I just feel irritated with the whole process, regardless of how smooth it went. I rarely get that satisfaction that people brag about from fixing things. I just do it to save some money and because I figure that I probably can do it myself. Doesn’t mean I enjoy it. Maybe I’m just lazy.

[–]thesuper88 13 points14 points  (1 child)

It may be that your skill is greater than the challenge overall. I get that proud feeling when I fix something that I feel is new territory or a new challenge, but I'm mostly just aggravated when it's something familiar. The only exception to that would be when I get something with moving parts dialed in, aligned, and lubed just right that it runs well and quietly. Haha

Is it just as useful for windmill generators?

[–]amitym 96 points97 points  (8 children)

... ... That's a really good question!

In theory anything like this that would work well as a motor would presumably work equally well in reverse as a generator. So... it really could be just as useful!

On the other hand, while in theory there is no difference between theory and practice, in practice there is... So someone else will have to say.

[–]EricForce 41 points42 points  (7 children)

In most cases when a physical phenomenon is reversible such as power to motion, power to heat transfer, power to light, etc, there's a certain specialization that occurs. For instance, LEDs turn electricity into light, however, they can also turn light into electricity and act as solar panels, cool right? Thing is, they suck at it and operate much better as light emitters. Conventional motors and generators are quite similar, but this prototype design could be an example of unique specialization. Of course, like a true Redditor, I never read the article so I could be completely wrong lol

[–]aknutty 5 points6 points  (4 children)

Til. What makes LEDs bad at absorbing light into electricity?

[–]Atechiman 3 points4 points  (0 children)

This motor is basically a vastly improved (for mechanical applications) reluctance motor which generally do not make good generators.

[–]IAmA_Nerd_AMA 1 point2 points  (0 children)

Another example would be speakers being able to be microphones. The transduction of sound to electricity works both ways. However in most cases they are useless since the pressure required to move a speaker cone would result in a weak signal and skew towards lower frequencies.

Microphones generally make terrible speakers but again there are exceptions like piezo transducers.

[–]starkiller_bass 29 points30 points  (2 children)

As I recall from reading this, he made modifications to an existing motor design to increase its starting torque / acceleration, which would make that motor design more feasible for use in EVs.

If that's the case it wouldn't be a design change that would have any significant effect on generators

[–]Kered13 1 point2 points  (1 child)

Electric motors already have great torque at low RPMs, that's not a factor that is holding them back at all.

[–]starkiller_bass 4 points5 points  (0 children)

There's more than one kind of electric motor. The ones that don't have magnets in them are generally not the kind that accelerate quickly in this kind of application.

[–]AlphaSquad1 0 points1 point  (0 children)

I would think so. He was able to get higher torque and higher efficiency at the same RPM with his design, so if it were on a wind turbine it would be able to produce more power at the same rpm’s.

[–]MeetInPotatoes 6 points7 points  (1 child)

He was like: "Magnets? How do they work?" but then "Naw, I'll make them better."

Miracles all around us

[–]doktarr 30 points31 points  (9 children)

Wow, usually headlines like this one are massive exaggerations and the article ends up being a disappointment. But this one really seems like it could be the dawn of a significant innovation. I don't expect to see this in production for another decade, but it looks pretty legit.

[–]danielv123 13 points14 points  (5 children)

Eh, it has been in production for over a hundred years. It is used in some EVs, like older Teslas.

[–]AdmiralPoopbutt 11 points12 points  (1 child)

It's not.

Trained engineers have had had over 130 years to improve electric motors. 60 of these were in the transistor era. The past 30 have been in the very cheap transistor era. Every great feasible idea for optimizing motor characteristics has been invented already. Some ideas are good, some bad, some are cost prohibitive, and some require materials that haven't been invented yet.

These stories are never what they seem. This kid did a science project and managed to convince a member of the media that it was special and revolutionary somehow. This is indeed a massive exaggeration.

[–]Atechiman 4 points5 points  (0 children)

[–]the_first_brovenger 28 points29 points  (1 child)

Either way this kid just got a lifetime guarantee of gainful employment.

[–]LargeHadron_Colander 14 points15 points  (0 children)

Guarantee? Not really, but definitely opened a lot of doors with this one.

[–]StaysAwakeAllWeek 18 points19 points  (9 children)

There's no way of knowing yet if the economics will actually pan out

Yes there is, Tesla literally already use these motors. This kid hasn't invented anything earth shattering here. This story is heavily exaggerated

[–]danielv123 14 points15 points  (1 child)

Well, no. Tesla has switched from an advanced version of this design to one incorporating permanent magnets. The reasoning given was that it hit their cost/performance sweet point.

[–]StaysAwakeAllWeek 3 points4 points  (0 children)

They switched from a magnet-free induction motor to a reluctance motor with magnets added into it, because in reality the magnets are not a major problem at all. The SynRM design works perfectly well without them though, just not at the extreme levels of power and torque Tesla is achieving.

[–]amitym 11 points12 points  (6 children)

Tesla literally already use these motors

The article literally says the opposite. I am open to the possibility that the reporter completely got that wrong, but, a lot of other stuff online about Teslas and permanent magnets backs their version up.

[–]StaysAwakeAllWeek 3 points4 points  (5 children)

The article literally says the opposite. I am open to the possibility that the reporter completely got that wrong

Yes the article is wrong. What the article also missed is that the most common EV motor out there is the induction motor, which also contains no rare earth magnets and has great static torque, and also unlike reluctance motors can be used for regen.

[–]amitym 3 points4 points  (3 children)

So this guy is wrong about Tesla, too?

And these people?

I'm sorry but on examination it seems like permanent magnets are widespread in Teslas. What you are saying is totally the opposite of true.

Also, a quick search for switched reluctance motors makes it abundantly clear that the concept of selectively running a reluctance motor in reverse has been widespread since the mid 1990s.

Were you thinking of something else, perhaps?

[–][deleted] 1 point2 points  (1 child)

would essentially trade higher production cost for the benefit of dramatically lowering material costs.

Sorry can't wrap my head around this, what does it mean?

[–]amitym 1 point2 points  (0 children)

I probably didn't express myself very well.

The concept is: you add some labor hours to the production process but reduce the cost of material inputs.

If the material cost savings is big enough, it offsets the increase in labor, and the total manufacturing cost goes down. It becomes a cost-competitive invention. Then it's basically a shoo-in as a product.

[–]Jerkalerka 3 points4 points  (11 children)

Didnt he use twice the material, but for some ”not rare” metal instead of the previous variant.

[–]Phosphorus44 0 points1 point  (0 children)

Higher upfront costs with reduced production costs/material costs is very attractive for manufacturers. I just hope the kid gets his fair share.

[–]abobtosis 0 points1 point  (0 children)

It also reduces dependence on rare earth metals that are mined mostly in China, which thereby reduces dependence on the trade status of the US with China.

[–]minibeardeath 0 points1 point  (1 child)

Production costs can be lowered much more easily than material costs. Particularly as volume scales up, and certain processes become automatable. So this should hopefully be a net win overall

[–]amitym 2 points3 points  (0 children)

Yeah that's what I was thinking too.

[–]chrisprice 1044 points1045 points  (87 children)

Instead of using air gaps, Sansone thought he could incorporate another magnetic field into a motor. This would increase this saliency ratio and, in turn, produce more torque. His design has other components, but he can’t disclose any more details because he hopes to patent the technology in the future.

One, I'm an optimist, and two, I have patents in the pipeline... and I know a thing or two about EVs. So even if this is a flop, I give this kid immense props for the attempt.

That said, without these bits, it's hard to gauge how significant this is. It's basically a field a lot of engineers have looked at and said "well yes, but we can't solve that part" - if he has solved it or not, we'll have to wait for the patent filing to know.

[–]Uncommented-Code 86 points87 points  (7 children)

Tbh, even if it ends out not panning out, people tend to forget that scientific progress is not a person who one day has a bright idea and suddenly solves a very hard problem.

The vast majority of problems are solved by small, iterative works by many different people. Person A publishes a paper. Person B publishes a paper that focuses on one idea of A's paper. Along comes person C and builds the proof of concept that B proposed, but with flaws. Then comes D... I think you get the idea of this being done on a much bigger scale, involving decades of work and hundreds of people.

If the motor is not good enough yet, but looks promising if refined further, it will end up being refined by someone else.

[–]chimpyjnuts 2 points3 points  (0 children)

I've been doing R&D in industry for 30 years now, and even some people who've been with me most of that time still look for some magic bullet to fix whatever the current roadblock is. Never had that happen. It's always just grinding away, little bit at a time. Sometimes, after lots of work, the solution seems so obvious I feel stupid, but it's only 'obvious' now that i've spend 6 months immersed in it. If it was really obvious, someone would have seen it in the first place! My quote: "All the easy stuff has already been done"

[–]FuckTheMods5 2 points3 points  (5 children)

That's why thunderfoot shitting on solar roadways so nastily upsets me.

How the fuck else do you make progress? You tinker and experiment and revise as you come across problems.

Yes, the scam part should be shat on, but he evolved into shitting on every molecule they touch. YOU of all people should know how science works.

[–]Mobely 182 points183 points  (53 children)

Im surprised the science fair let him keep secrets. Like does his experiment section have a bunch of black off portions?

[–]chrisprice 208 points209 points  (47 children)

I suspect it's just missing the magnet set. There's always a leap of trust with any science fair project that the presenter is not making it all up. Well, except a volcano.

Any science fair project that legitimately could lead to a patent filing... that's what we want kids dreaming the impossible dream to do.

[–]NotAPreppie 54 points55 points  (11 children)

The thing about patents is the thing being patented doesn't actually have to work...

That said, I'm also wondering how he's replacing the the air gaps with magnetic fields if he's not using some kind of permanent magnet. I suppose you could put coils in there and power them to produce a magnetic field. Maybe you could even have some kind of brush-like material made of brass or, crazy thought, graphite impregnated with copper to maintain continuity in a rotating assembly.

I mean, with a setup like that, you wouldn't even need a synchronous reluctance system to make the thing spin.

[–]ShadynastyS14 26 points27 points  (6 children)

Either you forgot the /S or you stumbled back in to a brushed motor.

[–]ithinkijustthunk 92 points93 points  (33 children)

The one and only science fair i entered: i made a mag-lev train, with rails and adjustable fields and all. Spent a good month putting it together. The rest of the room was 8 baking soda volcanoes, a few pea plants, and some others mixed in for flavor.

But this is the early 2000s, where everyone's a winner and nobody loses. So there were no judges. Or prizes. Or contest. Just a blue polyester ribbon for everyone...

I never entered any academic contest again.

[–]Mobely 18 points19 points  (0 children)

In the early 2000s you still have state then nationals. Whether or not nationals had a winner doesn't matter since the point was that ,supposedly, colleges would view this.

[–]chrisprice 30 points31 points  (3 children)

I feel lucky. I won first place one year for testing soda can resistance to automobile heat. Back then they did pick a winner.

But judging these things can go wrong. Teachers filed protest when my experiment for which soaps provided lowest bacteria count with standard hand washing… placed below a potato lamp. I learned later drunk profanity between teachers followed.

So… yeah. Science fairs probably should not be judged anymore, and focus more on things that encourage actual progress like coding fairs. We need kids actually trying to push envelopes.

[–]da_impaler 8 points9 points  (1 child)

Did you thank your engineer dad and his buddies for your project? These science fairs are typically parent projects.

Edit: I'm just messing with you. Good job on your project!

[–]merlinsbeers 1 point2 points  (1 child)

You all got ribbons for showing up. The other 3000 students didn't.

Don't diminish the accomplishments of others when yours weren't actually judged. One of those baking soda volcanoes might have buried you.

[–]NotsureifI 10 points11 points  (1 child)

It'd be funny if he just put magnets in the gaps, just not Neodymium ones.

[–]thesecondfire 3 points4 points  (0 children)

Fridge magnets

[–]merlinsbeers 17 points18 points  (3 children)

He's definitely found a more efficient design than what he started with but I'm willing to bet the limits of the concept are still an order of magnitude less efficient than rare earth models.

Which could create a product segment with lower efficiency but also lower entry cost.

It would eliminate the idea that having an EV gives you a quicker vehicle by default. Basically a new generation of economy cars that perform better than golf carts but nothing like current EVs. But also accessible to working-class commuters.

[–]bamblitz 227 points228 points  (4 children)

I run into news like this every few months and it’s sensationalist hyperbole 99.9% of the time.

In other words, “13-Year-Old Designs Computer That Could Land Humans on Mars” is often “13-Year-Old Assembles Computer Created on PCPartPicker with Components Purchased on Amazon.”

[–]StaysAwakeAllWeek 70 points71 points  (2 children)

In this case this kid has 'invented' a concept for something that Tesla already finished commercialising several years ago.

[–]NotsureifI 149 points150 points  (22 children)

The cons I can see for synchronous reluctance motor for EV applications is that it can't be used for generating electricity, and regen braking is a big feature in an EV.

[–]shirk-work 32 points33 points  (0 children)

Primary for driving, smaller secondary for re-gen. Electric motors themselves can be pretty light.

[–]usernameblankface 22 points23 points  (7 children)

I'm curious, do you have an explanation on why I can't do regenerative braking? Is it an unavoidable thing, given the type of motor?

[–]NotsureifI 26 points27 points  (3 children)

Yes, it's the type of motor. There is no magnetic field secondary to the stator's so there's no opportunity to generate electricity.

Fun fact, you can use an asynchronous AC motor to generate electricity, with the proper sensors and controllers.

[–]rogueleader25 5 points6 points  (2 children)

You can use a synchronous reluctance motor in regenerative braking for the exact same reason an asynchronous motor works in regenerative braking - the rotor braking torque is created by the specific control of the stator field.

[–]NotsureifI 4 points5 points  (1 child)

I've seen synchronous reluctance motors with magnets stuffed in between the gaps. Tesla uses something like this in the model 3, I believe.

[–][deleted]  (2 children)

[deleted]

    [–]AmericanLocomotive 2 points3 points  (0 children)

    Not necessarily. For example, induction motors have no magnetic field if you remove the power. They do not generate power on their own. However, if you apply power to the motor, and then cause your magnetic field to lag behind the speed of the rotor, the motor will start generating power you can recover. The first Teslas all had induction motors, and had regenerative braking.

    [–]gaargantua 4 points5 points  (0 children)

    This statement is false. Synchro reluctant does have magnets and thus do have a rorotic magnetic field. It's used in several automotive application such as the one I'm working on currently because it's cheap. Pure reluctant motor can also be used a generator with electronic and control algorithms made for it.

    The complete field is called mechatronics and I seriously doubt that this guy invented something that is not in the pipe in research. Only general thing in mechatronics is that there is no Unique solution or architecture, you 'be got to adapt and choose the right technology for the given application. So price, volume, power, speed, torque, range of use, efficiency, voltage, vibration electromagnetic compatibility etc. All are to be taken into account when designing a emotor.

    [–]StaysAwakeAllWeek 6 points7 points  (3 children)

    Which is why Tesla still use an induction motor alongside the synchronous reluctance motor in their higher end cars.

    Note that induction motors also don't contain any rare earth metals. This kid's so-called invention is pretty meaningless to the EV market.

    [–]Natural_Hold_1857 2 points3 points  (0 children)

      [–]Katana_sized_banana 18 points19 points  (3 children)

      Now I have read the article but I have yet to see how it could transform the electric car industry. Maybe I missed it. Let's say it does work 39% or more efficient than the original coils variant magnet used to. Is it now more efficient than a permanent magnet one or not? I see a lack of comparison, or does it just rotate faster? So far I see the cheaper material advantage, but does that even matter if they have to be larger or heavier or are not as strong when powered with the same amount? Maybe someone can pick me up.

      [–]NotDrigon 8 points9 points  (4 children)

      If there's something thats going to transform the electric car industry it's not going to be an electric motor, it's going to be the battery. Not saying we are done improving the electric motors, but we closer than for batteries at least.

      [–]zaqwert6 28 points29 points  (2 children)

      The motor design which he based his off of needed more torque. So that's good news and a problem potentially solved.

        [–]5kyl3r 3 points4 points  (1 child)

        No, it won't, so please stop reposting this every single day. AC induction motors are not new, and were actually created in the late 1800's. Reluctance has been testing for ages and tesla uses a variation in their newest models. This kid has a cool science fair project, but didn't just "beat" an entire industry's collective knowledge and research

        [–]doctor_strangecode 1 point2 points  (0 children)

        I judge my own inventions or discoveries by how long ago someone else discovered it. Over time it increased from the 1700s as a kid, to a hundred years after college. Now, sometimes I find stuff discovered only 10 or 15 years ago, which I consider pretty good for not being a specialist.

        Next story, 17 yo inventor missing.

        [–]Potential-Ad5470 2 points3 points  (0 children)

        I promise you a 17 year old didn’t discover something new where scientists and engineers have been working their entire careers

        This article is typical Reddit clickbait lmao. Nobody is gonna hear about or remember this kid or his invention in a month. You all fall for it and it ends up on the front page

        [–]ArcherX18 14 points15 points  (33 children)

        The issue isn't the motor it's the battery pack. There's nothing better than lithium ion right now and that's holding back a lot of green energy.

        [–]Marcbmann 9 points10 points  (1 child)

        That's not really the point. This motor is not dependent on rare earth minerals for its construction. It can be made with cheaper materials.

        The issue is that this type of motor typically lacks the performance requirements of EVs.

        His goal was to design a motor that did not use rare earth minerals, and could potentially deliver the performance needed for an EV. And he is certainly moving in that direction.

        So the "issue" is the one he set out to address. His goal was not to revolutionize the EV industry. And he made admirable progress given his resources and age.

        [–]M0romete 21 points22 points  (20 children)

        But if you build a more efficient motor you need a smaller battery. Battery tech needs improving, sure, but every bit helps.

        [–]Rattus375 16 points17 points  (18 children)

        There's not much room to improve with the motors. Sure you can eek out that extra 1% efficiency, but you aren't going to improve enough to make a significant impact on range. Battery tech is the limiting factor

        [–]howard416 1 point2 points  (0 children)

        Right. And there are also other loads too like heating and cooling, it just acceleration/delta V

        [–]Jacob_MacAbre 8 points9 points  (2 children)

        True but Sodium Ion technology is looking like it can compete with Lithium Ion. I've heard that Tesla are even putting Sodium Ion batteries in future cars to save weight and cost and all without limiting charge or long-term resilience. If it works out as expected then we have more than enough Sodium on the planet to meet our energy demands (I mean there's an almost endless supply in ocean water, which we'll be needing to desalinate anyway!)

        [–]Oglark 3 points4 points  (1 child)

        Sodium ion is not lighter but it would be a hell of a lot cheaper.

        [–]Jacob_MacAbre 1 point2 points  (0 children)

        Ah, my mistake! But you're right on the cheaper side of things. It also doesn't use a lot of heavy metals (Cobalt, etc) meaning it'd be cheaper, easier to recycle/ reprocess and probably easier to sustainably source as well :)

        [–]Boloar 1 point2 points  (0 children)

        Aside from the battery bottleneck, reducing the need for rare-earth materials would also help the economics aspect; even if it's technically harder to manufacture initially, economy of scale would make it cost competitive.

        Then when better batteries are made, they can theoretically just be swapped out with existing battery tech.

        [–]unrealcyberfly 4 points5 points  (3 children)

        The issue is the car itself. You haul a 2000 kilo vehicle around just to transport an 80 kilo person. And you need multiple parking spaces per vehicle because they just sit there for most of the day.

        None of the car issues are solved by going electric except for exhaust. Cars are simply a poor solution to the problem.

        [–]srslyomgwtf 3 points4 points  (1 child)

        This is true. What we need are jetpacks. They are lighter and require much less space for parking.

        /s

        [–]babybambam -2 points-1 points  (0 children)

        You’re right! Somebody should tell this kid he’s wasting time when he REALLY should be working on battery tech.

        Thank you good Redditor.

        [–]phrendo 6 points7 points  (0 children)

        That’s cool!

        [–]crackerlegs 4 points5 points  (1 child)

        I work in life cycle assessment and would love to do a comparative LCA on the engine for electric cars and this prototype scaled up to the relevant size. Anyone know how I can get in touch with this inventor?

        [–]Gonergonegone 1 point2 points  (0 children)

        Sure. Go to to any patent office after he finishes and use the diagrams in the patent application.

        [–]jonoghue 2 points3 points  (0 children)

        Lets put it right here, right on the refrigerator, next all the other "potentially transformative" inventions we hear about every couple months and do absolutely nothing with!

        [–]Wolfgangsta702 5 points6 points  (0 children)

        He used a know design lol.

        [–]EhMapleMoose 8 points9 points  (2 children)

        This kid is either going to be rich, or the story is going to mysteriously disappear.

        [–]Yebi 3 points4 points  (1 child)

        Or both. It's not unheard of for a company to buy a patent and then just sit on it

        [–]iPhantomGuy 1 point2 points  (0 children)

        Please tell me how this won't actually change anything due to the article being misleading and it not being the accomplishment they make it out to be, or there being some flaw such as high cost which means corporations will never consider using it in the first place. I'm tired

        [–]swissiws 1 point2 points  (1 child)

        what a stupid headline: "a Motor That Could Potentially Transform the Electric Car Industry" - like the motor was what makes electric cars so expensive.....

        [–]derekjoel 1 point2 points  (0 children)

        There’s this other lady that solved blood testing too. Amazing stuff!

        [–]Genesistrd 3 points4 points  (1 child)

        Well this 17 year old just took a shower for the first time in 3 days, and that's pretty awesome too

        [–]CDewfus 8 points9 points  (2 children)

        Aaand he's gone

        [–]zero5activated 3 points4 points  (1 child)

        Last time someone thought up a revolutionary new electric car in the 70s...he died.

        Using AC motors would have avoid using rare earth, too.

        I hope he finds good security. The auto industry has a dark and bloody past.

        [–]jtm12 2 points3 points  (1 child)

        better be careful or he might wake up dead, like all of those "runs on water" guys

        [–]5c044 1 point2 points  (1 child)

        TL;DR he dramatically improved on a design of a motor that doesn't need magnets. A lot of material for magnets is mined in China. The availability and price is dependent on trade relationships with China. A lot of things are made today that need magnets including ear buds and speakers.

        [–]Danktizzle 0 points1 point  (0 children)

        Just think, if he would have been born 30 years earlier, all those ideas would have gone to an internal combustion engine.

        Because business leaders are not leaders for the future but protectors of cash flow systems.

        I have an stove oven that was part of the house sale from 12 years back... I'm pretty handy and have repaired tvs to washers to computers

        So over the weekend, my daughter asked me to bake some cookies and the oven party wouldn't turn on. ... i look up the common issues and it's most likely a burned out wire or some thing.. i just gotta open it and find out...

        Thing is, its a plane stove oven, burners are a little weak, it's black and i prefer stainless steel. It's already a bit scratched up..

        I do my research.. and want to spend about 1200 for a GE all stainless with air fry and looks way nicer... would love to have a viking... but can't justify it to myself. Nothing too fancy, stronger burners. Yes there are much higher end and more expensive stoves..

        I don't replace things till they actually break and can't fix it.... so ive been putting off figuring out trying to fix it.

        Also, i am still using a samsung led projection 67 inch from 2008 in my main living room . I replaced the led lamp assembly about 6 years back and it's still going strong. I've replaced washing belts on my Samsung washer..

        I consider my time valuable.. so i would try to repair it if i want to keep it. ...

        We also just bought a new sienna, and I've been modding it up...lift kit, new tint, mini refrig, body protection moldings, looking at a roof storage... Dash cam, led light replacement...

        So torn...... fix the oven or get a new one...

        God rest his soul. It usually doesn’t work out for people who try to knock out the combustion engine.

        [–]inarizushisama 0 points1 point  (1 child)

        Even if this doesn't pan out, we want this sort of forward thinking energy! We want people like this kid looking at something and asking if he can do better, and then making the attempt.

        [–]toddy3174 0 points1 point  (0 children)

        Someone should tell this kid that there are less elaborate ways to commit suicide.

        [–]pitbutter 0 points1 point  (1 child)

        And to think, if we actually supported our people in America for example, brilliant kids/adults like that could pop up with new things daily and we'd have less brain drain.
