Exactly my thoughts on the topic of invention, all an effort of the collective. “Many people doesn’t fully realize what they are made of. They don’t know the creation of things. Where the things that form our lives today come from. Our roots, without them we can’t stand on our own. That’s why they are swayed by rumors without roots” - Daisuke Igarashi. But then again i wouldn’t say plagiarism is a bad thing, sapiens neuron system are based on information/pattern copying. Technically we are all natural laws plagiarizer. Claiming an invention to themselves is still arrogancy though. Also realistically speaking a human can’t truly own a method to make/invent something, socio constructs made it all possible..

I think those are 2 separate issues. The fact that all invention is a series of incremental steps taken by our species; applies to all invention and is thus superfluous. The issue at hand; is perception that Edison (intentionally or otherwise) has sapped all of the credit/recognition *from his contemporaries/employees*. In contrast; someone such as Swan (or Tesla) comes off as a 'nerd beavering away in his garage'. I don't know what aspects of the lamp; Edison actually invented/discovered (perhaps you have come across some relevant sources while researching?) but I'm inclined to view him the same as I do Steve Jobs or Elon Musk -Jobs is not a computer scientist/engineer and Musk is not a rocket scientist/engineer; they are businessmen, innovators and perhaps 'visionaries'.

Assuming the bulb dates to the 1930s or earlier most if not all homes during the early days of electrification, were actually supplied with 110 volts, or 110/220 volts. To understand why, we need to go further back in time, when Edison designed and opened the first power plant in NYC in 1882. His supplied 110 volts DC using large dynamo. At this time, electricity was only available locally, as the voltage drop was such that after a mile it was unless, and only the wealthiest of families had their homes wired, using knob and tube. Then, a few years later, Nicola Tesla improved and patented the power grid using Alternating Current, or AC. This was a huge success, because, using banks of transformers we can step up the voltage greatly to transmit long distance, then step down the voltage again, before it enters the customer's home, and 110 volts AC was chosen, so as to be backwards compatible with Edison's lamps. Only when AC became widely accepted and used, was it possible that the average homeowner could afford the many conveniences made possible by having their homes fitted with electrical wiring.

I think it's fair to be able to both recognize the innovations and good someone brought to the world, while also acknowledging the shady and messed up things they did along the way. Edison was a genius, who brought lesser known inventions into the limelight that would become indispensable to the world, inventing some of his own, legitimately, along the way; but he was also a genius that used people to further his own image without proper accreditation, even when he knew the inventor, and supported people who did horrible things, such as Brown, if they worked in his favor. Recognizing the good and the bad of great historical figures' actions is how we can grow over time to filter out the bad, and encourage the good.

Philo Farnsworth is often credited for inventing the first electronic television, but it wouldn't be possible if Ferdinand Braun didn't make the cathode ray tube, which wouldn't be possible if J.J Thomson didn't demonstrate the ability to deflect electron beams. Electron beams wouldn't be possible without the discovery of the electron thanks to J.J Thomson and his contemporaries, or electromagnetism thanks to Michael Faraday.

It produced a lot of light and heat, and lasted for several minutes before it died.

If the only laser we had today was huge ruby apparatus, we would still be wondering "what's it good for". After something has been invented, the engineering required to make it practical is often the most important part. And Edison was ultimately an engineer, not an inventor.

Edison's greatest invention was that of the industrial laboratory. He hired skilled artisans to do the work that he wasn't skilled at, such as glass blowing, running a lathe or milling machine, and in some cases doing complicated math. Edison's inventions were in many cases based on the previous work of others that had reached a dead end. He would read up an the current state of the art, and then see how he could build upon it. This is not theft. As Newton had said, "If I have seen further it is by standing on the shoulders of Giants”, so did Edison. Edison was also a shrewd businessman as well as an inventor, the Bill Gates of his time.

Yes, and no. Edison does deserve a lot of credit, and a lot of criticism. Like all human beings he was a complex character. He was instrumental in the introduction of low-cost, long-life light bulbs, but the implication that we wouldn't have had them for well over a century had he never existed is where I disagree. There were so many other people working on this problem that we would have gotten there maybe just a few years later. While Swan's bulbs had the issue of requiring high current, it seems very likely he would have refined his design and manufacturing until he overcame this short-coming (BTW, he also was pulling a vacuum, initially using his own Sprengel-like pump that he invented two years before Herman Sprengel, but later using pumps supplied by Sprengel himself, just like Edison was using). If he had not done so, other people would have jumped in seeing the commercial opportunity to beat Swan.

Fascinating! I love the detail on the patent specs.

You are Missing out on what Edison really did in making the light bulb and the process he ended up with. Unfortunately, this is detailed in only one publication that I have found. It is "Cyclopedia of Applied Electricity", volume 3. (I have hard copy of this book in very bad shape, which I spent enormous time scanning.) This series of volumes is on Google Books, but the volume 3, despite claiming to have "electric lighting" in frontispiece like my book, is not included in the table of contents, nor its pages. (I have PDF of book, and I think it is legal for me to share it. If you provide me place to send it, I will.) Very short explanation goes like this: cotton is boiled in zinc chloride solution. It turns into gummy goo. (Edison invented plastic!) This goo is extruded through tiny orifice into alcohol, which hardens it into a fiber. Fiber is passed through boiling water to remove zinc chloride, dried, and reeled. This fiber is pyrolized (as you did) into carbon filament. On purpose, filament is made "too thin". Filament is mounted into bulb base with tar binder as you did. Next step (you sort of did for a different purpose) is to insert into chamber filled with gasoline vapor. (Edison called this "flashing".) Power is turned on, and hot filament builds in diameter as gasoline "cracks" and adds layer of graphite. This makes filament stronger, and more importantly, uniform in section (thin area is hotter which builds faster). When resistance drops to desired value, relay cuts off power to that filament. Filament/lamp base is glassblown onto lamp globe and evacuated. Edison used a "getter" to scavenge gases in vacuum. You can use a 2nd filament, or better, a pinch of red phosphorus applied to the filament (converts to white, then scavenges oxygen). Since this involves a utility, you need to explain the "voltage squared divided by resistance" problem regarding the amount of copper required to transfer "X" amount of power "Y" distance with "Z" efficiency. Because Edison was "stuck" on DC, the voltage in the transmission lines had to match that of the lamps.

Going into vape coils is alot like going into electric water heaters. With the addition of worrying about metal vapor in your lungs. Even with the perfection of vape coils to eliminate metal vapor, it still scares me. Therefore, you have additional factors needed ontop of your basic "battery powered glowy heaty wet thingy", a very interesting design.

Impressive. I like how you put things in historical context. Very well done.

What an engrossing video! It's fascinating when you touch on the history.

Really great video! Highly informative. I made a video a while back showing how a load lamp works, it's just like what you did at 12:55. It's very useful for testing.

I really enjoyed this video. It reminded me of my own experiments as a boy in the 1950's trying to make a light bulb. For a filament I used the spring from a ball point pen. As did Edison, I used direct current. In my case I used the transformer from my electric train set. To eliminate the oxygen in the glass bottle that I used as a bulb, I dropped in a lit match before sealing. The results were only fair with little light, but a little better as I turned up the voltage.

The parrot during the sponsorship section is pure genius! All youtubers who have pets should seriously consider doing this.

Edison's work as a patent breaker required a certain kind of smart. He was a very smart man. Definitely agree that he deserves quite a bit of credit in the inventions he brought to market. Ideas are one thing. getting a competitive product mass produced is a whole different area of expertise.

Mr Teslonian has a lot of good gasifier videos.

I appreciate that intro. We all too often caricaturize historical figures when we attempt to categorize them. As our understanding grows, the emerging picture is rarely black or white. In my own reading of Edison, I've found him to be as brilliant as he was interesting. He changed the world through innovation; he was far more than just a catalyst or organizer. Naysayers most often voice from a position of ignorance. Or comfortable laziness. I mean, given how many ideas the guy is tied to, who now is really in a position to judge him? lol. Awesome content.

What a very interesting video. Really liked the history on the subject aswell. You could probably start a whole series re creating technology like this

I love watching your videos and your channel is one of the few genuinely amazing ones out there. KZread automatically turned notifications off for me, and I'm assuming that's happened for other people as well. Its been happening with other channels a lot as well.

The way I typically describe Edison: "He was a decent, but not exceptional, scientist; but he was a phenomenal, but very shaddy, business man." He did personally invent many amazing things and thought out many more, but he also all but outright (and in some case fully outright) stole many more via legal machinations. That latter may have been quite the norm for business leaders at the time, but that doesn't make it right.

i agree, he was smart/devious enough to know that there were other people who were 'smarter' than him and knew how to harness these other people's minds to serve his interests. (having a paid 'mole/spy' in the local patent office was just one of the examples of his 'business acumen'). that said, he certainly advanced progress in the scientific fields regardless..

You cannot cast a historical figure in a modern context. It is a fools quest and utterly hypocritical unless it's with the humility that NiL describes. The people of those times ran under the rules of those times. What Edison did or did not do during his life is the subject of tons of speculation, conjecture and historical spin. I have never been a fan of his approach to patents, projects, etc. but what he did back then is still being done today under entirely 'acceptable' standards that people see as okay... it's only been given different clothing. Most of what he did back then would today be called "venture capitalism" which is also a poor turn of phrase. What people do on Patreon, or GoFundMe or any of the various crowd funding sites can draw the attention of larger money pools to buy their concepts outright. Those concepts are then taken in the hands of experts and fully developed into a working product. This is precisely what Edison and his various companies did. So why is he such a demon for doing this back then... even aggressively, when such things are done today... even aggressively?! Yet many of these modern Edison's are seen as Tech Gods and 'super brains'. Just goes to show that nothing has changed, yet hypocrisy continues. Yeah, best we stay humble in the face of creation... especially mans own creations.

I play Red Dead Redemption 2, the detail that went into this game is absolutely mind boggling. Some of the street lamps in the city of St Denis are carbon arc lamps. They stand out with their intense purple/white glow. Most others are carbon filament type and like in the video produce a dull yellow/orange glow. Like I said, they did their homework when making that game. This is something I've thought about doing myself for fun, making a carbon filament bulb. Good to see it done here.

Thanks for acknowledging Swan as an important contributor to the incandescent lamp, too many credit Edison alone.

I once worked with a fiber artist who used bamboo fibers -- an almost silky fiber that can turned into thicker strings and cords, and that looked like it would give you the needed consistency. This would be the mechanically separated bamboo fiber, not the rayon stuff derived from bamboo as it is no different from any other rayon -- WIkipedia has a decent overview of the difference. I've seen it for sale at various fiber craft shows, so it is available if somewhat rare.

@OgdenM

I love that you know that most bamboo fiber is really just normal rayon! Most people don't and sing it's praises about how much more eco friendly then cotton it is... and it's actually worse because of all the processes it has to go through to be turned into fiber that you can make clothes etc out of.

Yeah, certainly Edison wasn't as bad as it's portrayed, and according to a biography of Tesla I read, he even helped Tesla once when he had financial problems (which were a result of Tesla's contradicting mindset of wanting to give away his inventions to the world for free, and the same time, enjoying many luxuries, such as staying in the most luxurious hotel in the world). There certainly were other people who were more hostile to Tesla than Edison.

One of the improvements I saw was the extensive scaffolding used to string up the filament. A few pieces of wires insulated against each other to prevent short circuits and a length of string might do the trick.

Thanks for your Patreon support! Edison was an interesting character. He famously went back on a deal with Tesla and for that gets some deserved criticism. A lot of others liked working for him though, and being associated with the world changing inventions he spearheaded. There's a lot to admire about Edison's drive and innovative aspirations, but also a lot that's not so admirable. Both he and Tesla were anti-semitic, and outspoken supporters of eugenics. Not great. A lot to learn from historical figures, and a lot I'm happy to leave in the past.

Well he is clearly biased towards eddison so you should take it with a grain of salt.

Great experiment! Thanks for sharing you own experience on this subject. Cheers.

When Edison was still my boyhood hero, I read many stories about the light bulb he created and his work with bamboo. After many trials with bamboo from around the world and all the failures, he switched back to cotton thread and learned how to spiral the thread and carbonize it so the resistance was higher and it used 100 volts DC. He was very satisfied with this system and went on to make all the fixtures, switches, plugs, sockets and fuses required to wire a house properly. If you were to thin the pine tar, and coat the thread with it before carbonizing it, then wrapping the thread around a mandrel, you can make a good filament for a lamp.

I think it's misleading to praise Edison for organizing workers to produce things, we know that workers can self organize so the question should be why couldn't they do it themselves, and the answer is because of a lack of capital, they didn't lack some spark of genius that Edison had, he wasn't clever for owning stuff.

Your video “isn’t meant to address Thomas eddison being a fraud” but you repeatedly praises him and says he is not. it’s clear documented he was indeed a fraudster that would patent other people’s ideas. But he is also an American icon which is probably why you hold him in high regard. The patriotism is strong in this one

To be fair, even someone that may have done unethical things, still can be known for starting a revolution in designs or concepts. Especially during the time Edison was around, Tesla and other famous electricians were all "stealing" ideas from each other. But really, they were the one who brought the idea and lead the revolution. Nowadays, take any new invention, if it was designed under a company, the company has full ownership over the designs of the person. Do we call it "Disney's Ratatouille" or "Brad Bird's Ratatouille"? Sure the small guy directed it, but it was under work of the boss.
