This is great, I'm happy for him! But I miss the creative aspect in myself. I used to be so creative like him, with so many half-finished inventions scattered around the house. Today there's nothing. I finally managed to carve out a day or two per week away from my job to work on personal projects after many years of failed attempts to get away at great personal expense.

Your honesty was refreshing compared to others who jumped straight to hate, because there was no story about them as 17 year old inventors (so clearly he does not deserve it either).

But a magic bullet to rekindle the creative spark?

There is none.

Give it a rest and it will come back, or not.

Try something new, preferably somewhere else.

> No creative impulse, just worries about chores/bills/obligation

I think that's critical in many people's lives and I've felt it starting to creep in my, but I think I'm keeping it at bay. Based on personal experience, when you settle down and/or start family, chores/bills/obligations start creeping up on you massively. It's very easy to get sucked into a mindset that if you start falling behind on those, your life will start falling apart. In reality, a lot of those can be postponed with only minor downsides. Yes, you can live in a slightly dirtier/less organized house. Yes, the lawn can be slightly less maintained. Yes, you can probably postpone that car service another week. Just sit down, forget about the world [not] falling apart and enjoy your hobbies. Write some side-project code, start a hardware tinkering project that you're unlikely to finish. Disassemble a failing kitchen appliance to see if you can fix it. Those things bring way more to your life than the apparent utility!

In what all that resentment towards him is helping you or anyone?

No, but pointing out something that most people seem to gloss over. It is like reading "startup X raised Y dollar with a Z year old founder" articles and oohing and aahing while misunderstanding the actual circumstances that got them there. It is never about solely the product and idea, HN hates to acknowledge this but you don't raise money without strong connections and network, and it is the same story for science…

You're correct. Those factors are often overlooked. Kids don't even know that if they ask enough times, there are kind people who are willing to help them.

All this leads me to conclude that we need to do better so these resources to innovate and learn are accessible to all.

This is inspiring, and let's look at why so many of us have the impulse to figure out what the flaw or missing part of the story is.

For me, it's because I hadn't done something so cool at 17. That makes me think, huh, I wonder if I'm not a "natural born engineer". I start going through my life story so far and beating myself up for playing too many video games, or not going deep enough on my interests.

Then I start thinking about the ways my life is different from his. I start to feel resentment about the opportunities I didn't have, the resources that weren't available. What could I have done if things had been different?

Next I start to resent how society scores us on things that can contribute to the economy, or things that look particularly cool, and things that we accomplished at a young age.

And then I start to imagine the difficulties that this young inventor will have. "Oh yes", I think, "He'll find out soon enough what the REAL world is like."

And these thoughts are not who I want to be. But I can reflect and learn something about myself from them. And I can choose to go another way.

I can decide that, if a 17 year old kid with the right resources and a crazy idea can make something really cool, then I, as an adult with more experience and resources can make something at least as cool if I want to. And I'm going to. It's not like my life is over because I'm older than 17.

And if this article is making you spiral with insecurity, I hope you make a similar decision. A decision to be inspired instead of intimidated.

I’ve been there, more than once. I seriously doubt the creative impulse can be eradicated, it is just hiding.

The way I’ve gotten past this is to commit to messing around, or trying to make some small thing, at a specific time on a schedule.

(Every morning, whatever you have)

Make no rules about what is “valid” to work on, and give yourself permission to quit after a certain amount of time if you still aren’t feeling it that day.

The creativity will return as a result of doing. And it may take a form that surprises you, and wasn’t what you set out to focus on, because currently you don’t know yourself well enough to know what you are even interested in.

One day, during one of those periods, I sat down at my regularly scheduled time and I produced computer music for about 60 minutes, listened back to what I made and was absolutely disgusted by how mediocre it was.

I stood up to walk out of my studio and on a lark picked up my trusty 6 string bass. I then wrote this entire song in one pass:

Spotify

https://open.spotify.com/track/2erc0IdvaDh6xnprg8gthS?si=xX0...

Apple Music

https://music.apple.com/us/album/sometimes-you-need-sun-feat...

It just came out fully formed.

Relax, play, mess around, do little fun or interesting things. Let your mind wander. But sit down at your scheduled time.

Inspiration will return.

Earlier quoted context omitted.

Fair enough, but context matters and there are two that matter here: (1) The subject was the tech and the engineer not biased media narratives, and (2) HN is a forum that so many people look up to. So if you want to context switch to a discussion about the media (a worthy subject BTW) post a new thread; let's not do it on a thread that is spotlighting interesting tech from a promising engineer.

I would much rather live in a world where people question biased media narratives and we risk hurting someone's feelings than the other way around. If this kid can't handle a little bit of criticism, he won't be long for the engineering discipline.

That's a false dichotomy

> If this kid can't handle a little bit of criticism

I do expect adults - over 25 - to take the rough with the smooth. But children are not adults.

I think you're assuming your own competence at pedagogy. I would want to shield children from you until they've developed the resilience you demand from them.

Also, the emotional tone - sheesh

I don't think this is right.

I think instead GP can pick up the brush over and over again and make things happen with or without the creative spark. The point is to get inspired by one's own creation, not to create ex nihilo.

So, how is it in terms of efficiency? The article mentions that it's 31% more efficient than existing reluctance motors, but doesn't give a comparison to the traditional electric motors.

That's a very good question. I have an EV motor control and calibration background so lots to say here. First off, peak efficiency tends to occur at mid to high speed and mid to high torque, in other words high power. Most EVs spend very little time operating anywhere near their peak power. It may take as little as 4kW to drive down the highway at constant speed, but a motor may be capable of 100kW or much more.

Efficiency at 500 to 1000 RPM is important, and reluctance machines tend to be very poor at those speeds and low torques. So maybe he increased efficiency from 30 percent to 61 percent, which would be really good. Or maybe he increased efficiency from 50 percent to 65.5 percent (65.5/50 = 1.31 but I hate looking at percent change of a percentage). What he did not do is increase the max efficiency significantly at an already efficient operating point where most motors are already over 90 percent, and that's OK because like I said we don't operate up there very often.

BTW, IMHO the best way to characterize electric machines like this is not to look at their efficiency, but to look at their losses. There's a really nice way to plot losses but it's a bit hard to explain in a comment. He also doesn't seem to have a dyno which makes taking data and testing a lot easier.

Anyway, he did a great job and will undoubtedly continue doing so!

I was the same way only maybe not as productive as you. From a young age until some point I was always thinking always inventing.

I recall thinking if it was possible to not think since I was constantly thinking. I was well-known among my friends in pre-Internet times as knowing a lot of obscure facts. I was always reading anything from science journals to history mainly to get ideas for inventions.

One thing I have been toying with is a long fast. People say for them it reset their brain and they could think more clearly. And by long I mean days like a 7 day or more fast. At my age it would probably kill me.

> If his motor continues to perform with high speed and efficiency, he says he’ll move forward with the patenting process. Is it a wise move? Shouldn't he just file a patent application instantly? (It is not a kind of a sarcasm or something. I really do not know, and I'd like to hear from people experienced with patent applications.)

Probably. Given some years back the US moved to a first-to-file system, getting an initial patent application filed to establish that date is probably not a bad idea and isn't too terribly expensive.

Can be done for just the filing fee. But you'd likely want to have council help, about $6k last I looked.
