Hey would love to donate. Don't want to use Patreon and have recurring payments. Your tiers come out to be $12, $24, and $60 a year, and I think for the quality here and over the years, that's an easy range to donate each year. Unfortunately I don't see a way to do this. Do you have anything set up? If you do, that will be an easy donation from me. Thanks for everything you do!

There's a cardinal error in the video - the installed capacity of Hoover dam's electric generators is not 2 Watts as stated at the beginning of the video, obviously! A single AA battery would be more powerful. 2080 mW is 2080 milliwatts, that's 2.08 W. Hoover dam's installed capacity is actually BILLION times bigger - it's 2080 MW (megawatts) or 2.08 GW. Check the metric (SI) prefixes, please. Should an engineer do such mistake, he would be fired, probably (or someone could potentially die from such mistake).

Nice video. You explained everything pretty much correct. I worked for Hoover Dam for a dozen years and have been inside those Penstocks and Laterals during ‘water down’ (maintenance cycle). An interesting fact: the insides of the steel penstocks are coated with Coal Tar to prevent corrosion. No place darker than walking in one of the main penstocks. The water velocity in those penstocks doesn’t exceed 15 ft/sec.
@@havakuvvetleri2.anajetussu534 My own involvement was SCADA and Communications. However my work took me into dewatered penstocks and inside generators (sensor inspections). Great working in a hydro electric plant. I'm retired now.
Man do I love hydro power, but you would never see me within a kilometer of one because oh my god that is terrifying, being even on it is scary enough, but being inside of one of those pipes? fuck that One of my biggest fears is large water-based areas like this, not like, lakes and rivers and such, but anywhere with large amounts of moving water or just large moving parts, I would probably pass out being inside that There is this one corkscrew water elevator near me where the corkscrews are only like, a meter in diameter and only a couple meters long, and as cool as I think it is, it scares the shit out of me being even near it
@@crypticcreator4841You ever play Skate 3? There is this feeplay map where there is a huge tunnel going down then out that is long and pitch black mifway through. The Hoover Dam had this one huge intake i kept looking at thinking, "damn that would be a crazy pipe to spiral through before death"
I cannot say enough good things about this video, the quality of the animations and the depth of the explanation is very well done. I will be using this as a handy reference for my electrical students in my College Program. Thank you so much for providing the teaching community with such a valuable resource.
In fact, there is. Here's the Google Streetview of it: www.google.com/maps/@36.016694,-114.738919,3a,15y,14.54h,88.85t/data=!3m7!1e1!3m5!1sAF1QipNtHdmJ9wqqIvP6PJ3ItgOch67zU_bJlkLYLpb-!2e10!3e11!7i11700!8i5850?entry=ttu
One omission is that the power towers are also angled to direct cable weight force directly down the centers of the towers. If it was only to avoid proximity to the rock face, then vertical towers could simply have been much taller to make up the needed difference.
i really hope this channel survives and gets back views, cause there's just nothing like it on yt. when it comes to how things were build and work and things like that. it's just so well visually explained.
@@BariumCobaltNitrog3n Except Lesics has been doing these for 10 years. Animagraffs for 4. Lesics was there for us early on YT with clear, intuitive, and detailed explanations that showed others this is what was desired. They should not be in financial trouble.

@@enotdetcelfer I don't know how you came up with the corporations/workers analogy but there is no relationship or commitment and you want there to be one. You want the viewers to pay, but they don't. People watch what they like, that's it. No one is going to watch something out of pity or because they have been doing it for a long time. And what does "Lesics was there for us" mean?
Videos like this make us appreciate the efforts of the engineers and technicians in applying scientific principles a century ago for the benefit of humanity. Without these huge machineries and power monsters we wouldn't have advanced technologies we have today.
Tip for another video. When I visited the Hoover Dam some 20 years ago, I bought a part of the cable transferring the energy to Las Vegas. I use them to this date as a pen holder, cause the cable is hollow and cleverly constructed. It's extremely interesting and there's a lot of physics knowledge and experimentation behind that.
Thank you for everything you do. I’ve learned so much from you. I just started watching and became a $10 level on patreon. PLEASE keep doing what you’re doing!!!! You’re teaching the world SO much!
I have had the privilege of watching the old black and white video of how they made the hover dam and I was able to visit as well and now after watching this video, like Paul Harvey says, and that’s the rest of the story.
I've been to the dam twice and did the tour inside. This video did great explaining what I've always wondered about the intake towers and how they're made, I didn't realize they blasted out a hole to sit them in. I do know they use part of the diversion tunnel made when they re-routed the river. Amazing man made structure there in Nevada/Arizona.
Great graphics, thanks! What amazes me is that this, and like its contemporary, the Golden Gate bridge, was all done with slide rules. No computers. And slow communications.
Fantastic! The 6 Companies consortium or conglomerate brought together the most brilliant minds to create Boulder Dam. It was the predecessor of the cooperative work used to take us to the moon.
I appreciate your comment. Growing up in Vegas and having family here since the 1940s I've heard about the 6 Companies as being the conglomerate that built the dam and being responsible for the many worker deaths. Those are the two things always mentioned about 6 Companies. Your comment made me stop and think. The 6 Companies managed to build that amazing structure in that location with the technology of the time and with the extreme working environment and weather conditions. That is incredible. I can see how the processes that built the dam would be used to go to the moon.
@@hewhohasnoidentity4377 : Yes, I'm sure they would've had a much harder time had there been an OSHA around back then. The lives lost was tragic, and they should have been properly honored and their families compensated. I am pretty sure the planning group formed a predecessor to think tanks as well. There is a legend that they would find a problem and cast about deliberately for someone to come at it with a fresh perspective. In the case of the concrete, they foresaw problems with the chemical heat and so decided to bring in someone to come up with a view to scheduling and calculate some way to pour and save time, otherwise it would take decades to properly insure integrity of the layers. Someone suggested bringing in Baird Spalding, a research engineer who had worked with Steinmetz, who after looking at their problem suggested replacing the rebar with galvanized pipe through which ice water would be pumped. Special refrigerated pumping houses were then built and the cooling was reduced to about five to ten years rather than whatever they calculated. I tried to get details on the origin of this legend but never succeeded. It was an anecdote that Spalding's publisher told at Spading's wake.
They do not use permanent magnets in the exciter except perhaps a small one to get things started. They use a wired electromagnet. The field of the exciter can be varied to control the output of the main generator/alternator. Vertical alternators and turbines tend to float in the air and do not require a large thrust bearing. The magnetic field holds them up.
The provided information is commendable. Adding details about the purpose and geometry, such as explaining the significance of gradually varying areas in the draft tube, would enhance the overall informativeness..
The continued blessings of A. J. Wiley's genious. Not a statue of this man exists, but the giant dams and other water structures in the western US and around the world stand as working monuments to him nearly a century later! He was the first engineer hired for the Hoover Dam project, but sadly died before it was completed.
Excellent video and animations. I've watch many documentaries about the dam and have visited and toured it. Even with that, I learned a little more about it thanks to your video.
"But the high speed water that comes down had a huge impact on this concrete layer" 6:59 th-cam.com/video/EE29Hw-MFAY/w-d-xo.html This same logic can be applied to roads, where there are hills. Especially when heavy cargo laden vehicles come down a hill to the lowest point - I've noticed this is where many roads have deteriorated. Water also naturally flows to this point and could compromise it from underneath.
Good explanation videos that are being hurt in the algorithm due to constant reuploads. Each time a video is deleted and reposted hurts the views on the video, then they complain that the channel is in trouble.
In the video its said that the water exiting on the lower buckets is an "impulse" when it is infact "reaction" as the water leaves the blading. A mixture of impulse and reaction occurs as the water enters the turbine howexer.
The divers who have to inspect the intake towers + penstocks along with the rest of the Dam have some massive balls. I would get major Meglophobia just being anywhere near them
Very well done 🎉 Adding an explanation of how the water EXITS the plant would be great. It appears that having the outlets opposite each other virtually eliminates any energy the outlet water may have…which means the downstream flow is only as strong as the head of the river at this point. Right?
I think the animation showing the rolling of the drums that drive the cable way is incorrect. The animation shows them both rolling the same way (i.e., either both clockwise or both anti-clockwise). However, if I understand correctly, the cable from the drum at the top is connected to the right side of the carriage and the cable from the bottom drum is connected to the left side of the carriage. This means that when the carriage moves to the left, the cable from the bottom drum gets shorter and the cable from the top gets longer. It's the other way around when the carriage moves to the right. This means that the drums should be rotating in opposite directions. In other words, when the top drum is rotating clockwise to make the carriage go to the left, the bottom drum should be rotating anti-clockwise. And to make the carriage go right, the top drum should rotate anti-clockwise and the bottom drum should rotate clockwise.
Bit off topic, but it's crazy to me that Porsche designed a "Variable Geometry Turbocharger" that works very much like the turbines in Hoover Dam, with a similar governing mechanism and guide vane system.
Fun fact, the power plant cannot generate electricity if the water level in Lake Mead goes below 950 feet. It is now at 1066 feet, and usage of water in upstream has been too much for years, for the reservoir actually fill up.
