2:52 "I love that!" This right here is why this guy is a National treasure. He has an encyclopedia's worth of knowledge and wisdom, yet his love for engineering still gives him a child-like fascination with the nature of nature. It's infectious and makes me want to be as excited as he is. I hope to always have this sort of intrigue and wonderment about science for as long as i live.

The better you know your topic the clearer and simpler you can teach it. These videos are awesome and this gentleman obviously knows his stuff. You have another subscriber.

This guy has a really nice theme for his videos. Feels smooth and calming, yet lets you know that you're progressing through something significant. Really nice, when you think about it,

Great comment. I don't know how it took me eight years to find this great series. But, better late than never. 🤗🌻

I don't know if I'm more impressed with how the light bulb works, or with the way he took off the glass shell.

Lord thundering Jesus, does this guy make the best videos in the world or what? His presenter skills are excellent, his voice, tone, pacing, inflections, subject matter, and demonstrations are uniformly awesome. World class. He makes me revel in the engineering of things I'm not even interested in. Give this man a raise!

At the very least, just by wearing the glasses he’s got us discussing safety. This is what safety culture is all about. Doesn’t have to be perfect, because nothing is, but is on the forefront of our minds.

I loved that he also put the glasses on to burn the filament. Staying safe doesn't always have to take a lot of effort, but can save you a lot of pain (or worse) once in a while.

I love your ability to condense that amount of info in 3 minutes, and make it interesting and yet, not overwhelming. Wonderful, Than you!

I'd never believed that that much work is required to make a tungsten filament! :O

Wonderful speaker. Probably never watch your videos if it wasn't for your awesome announcer-like voice and the ways you keep us interested. Thanks!

Perfect engineer guy I have never seen from centuries

The thing I like is that everything you do is so concise. It's terrific.

Love how well produced these short videos are. Great work guys!

for the most part he is correct, however, not every filament is the same. I work in a plant that manufactures incandescent bulbs, and depending on the wattage the coil will vary in size and length significantly. from nightlight/christmas light bulbs to huge stadium lights, each coil is different. also, argon is not the only gas used. sometimes argon, nitrogen and xenon are used either in a mix or independently depending upon the light output desired. also, red phosphorus is used to coat the coil before it even enters the glass bulb, that way, when the bulb is ignited for the first time, the phosporous will destroy any contamination and oxygen that may have gotten inside.

Of all elements we have, tungsten is the only one capable of handling the high temperatures produced for prolonged periods of time while emitting enough lumens to be able to see.

Thank you Bill! Your videos are the kind of nerdy engineer-y content I crave but can find very little of around the web.

Bill, you give a wonderful and valuable service to the world. Please keep it up!

This channel is outstanding. Interesting topics, slickly produced, and radio-quality-voice narration. Thanks!

Awesome video. Short, straight to the point, and packed with information. Thank you.

You are truly amazing. I hope the frequency of new videos increase!

Dude i just found this channel and i cant stop watching videos 😂

Your passion for engineering is so inspiring.

I didn't know that producing the filament would be such a complicated process. There is one type of bulb that I find particularly interesting and it is the halogen bulb. I used to wonder what it is that makes it brighter and whiter than the regular bulb. What I found is that the halogen gas in the bulb makes it possible for the filament to endure a higher temperature without evaporating.

My local teacher used original lightbulb filaments to coach his after school runners about the limits of the human heart. I'm a lucky man.

So much love and respect for you sir..

You sir are amazing. Love your videos and the vibe you put into them!

What a wonderful insight and a wonderfully produced video, thank you.

These are truly brilliant, please keep them coming.

Another great video. Thanks. How many of you have gotten a burned-out bulb to come back to life by gently tapping it so that the broken filament fuses back together?

Words cannot express how much I love these videos!

Guys like you are the real youtube stars , and videos like these give a true value to the very concept of youtube Thank you sir

excellent that you noted Joseph Swan, great vids.

This is the first time I have seen Bill and this is absolutely wonderful. Thank you Bill :) What a wonderful teacher. (And I have had enough to know the difference lols).

“Coil within a coil” Coilception.

You are very nice, eloquent, knowledgable and practical. I wish I had a physics or engineering teacher like you.

great work guy. you are succint and knowledgeable. love how genuine you are

my grandpa was an engineer so I've always been interested in this stuff

yaaay, new video! this one was great too. can't wait for the next one!

The BGM played during your excellent presentation is very fantastic...!!!

Woah dude! Your explanation was impressive. Thanks a lot for taking time to share this information.

Nice. Bill, these are the most professional youtube videos I know of. Bar none. And this vid goes to show how seemingly cheap everyday objects are actually quite difficult to make and only became affordable though much effort. Gives us hope that some very desirable technologies like solar PV and lithium batteries may well become more affordable and dominate the generation of electricity for powering your (LED) lightbulbs.

This is so damn awesome, I'm so glad I randomly stumbled upon this.

I WATCHED YOUR ALL VIDEOS. THANKS SIR FOR SHARING AND DEMONSTRATING YOUR KNOWLEDGE IN SUCH A BEST MANNER WHICH HELPS IN BETTER UNDERSTANDING. MORE VIDEOS WILL BE APPRECIATED SIR.

I love the way this man explains exotic engineering 😁

from 2:00 to 2:30 is the best thirty seconds of video I have ever witnessed. Praise to the guy or girl that made that.

Thanks for the demonstrations!!

that is rough old school observational science. props for that work they did

A marvelous video sir!!!

i always feel so smart when i can understand this guys videos

thank you bill

Imagine being able to have a talk with Bill Coolidge about his process in developing the technique for ductile tungsten.

Your videos are so enLIGHTening lol sorry couldn't help myself :) Seriously tho, love your vidoes.

Amazing tungsten educational video. Thanks!

Great explanation, thank you!

As with many ideas, sometimes is not just about inventing something, but your ability to market it and sell it, that will ultimately earn you a footnote.

These videos are just too good

You sir, are doing a great service to mankind.

Didn't Coolidge say that if he had known anything about working with tungsten to start with he would never have tried to use it as a filament?

Thanks Bill, very nice

Very cool! Awesome channel

Maybe the most telling part of this video is how Bill stated the incandescent bulbs' days are numbered. LED bulbs are getting cheap; at the time of this post, they are outweigh their cost-to-life benefit. Yet it is so cool to see how something maybe you and I grew up on explained, and yet maybe one day we will show this to the future generation as an aside of how technology was when we grew up.

I love this channel

I am also an engineer but these small stuffs still amazes me. Great Vids.

You light up our lives sir!

This is exhilarating

I always wanted to know a lightbulb works! thanks man, your videos are awesome!

Excellent video, thank you.

Your videos are just great ! ...

and know i know about the coil within the coil i must rethink my life. nah. but srsly you just taught me something new and i'm glad for it. thanks man.

Million subscribers! Congrats!

I freakin love this guy. Wish I had him as a teacher/professor when I was in school. I would totally be an engineer of some sort.

oh man I love these videos

@goblend Those bulbs also are of a design that burns at a lower temp in a way the filament in them is more like what you'd find inside a vacuum tube. In newer bulbs they pushed up the temps to get a whiter light and switch from a vacuum in the bulb to argon to cut costs. Now there are long life bulbs they burn at a slightly lower temp which yields a more yellowish light and the filament has multiple supports to prevent it from breaking.

This is awesome.

moar vids :) this is really interesting!!!! I wish you could have a weekly episode!

you explain really good!

Fantastic stuff, very well made videos, very well done. thanks, kept my attention through out. Thom in Scotland. { & keeping my attention is not easy..That's a fact}

We really miss you man. Could really use a few of your videos during this shitty world burning situation we got going on

Amazing !

Fascinating.

So much class!

I like how he takes out a pipe cutter to slowly cut into the bulb to cleanly take the glass off, only for the glass to crack and pop out anyway.

You are awesome. Thanks for explaining.
