I seriously love and respect awesome engineering!
Austrians are one of the most innovative, efficient, under the radar bunch on earth. Their culture is productivity, efficiency, order, and organisation: if you are working, work hard and work well, and if you are on holiday, Its almost a crime to even be contacted, it’s break time. Amazing, country safe and efficient, it’s really a hidden paradise. I really feel privileged to have it as my new home. 🇦🇹🙌
8:17 "why you... you do know my reputation". Immediately he recall us on him crashed the Rimac 😆
I love Hammond's voice🥰🤗
Hurry up people the dam tour is about to begin we’ll Welcome everyone to the dam tour If you could please wait until the end of the dam tour with any of your dam questions 😆
That dam at 5:12 is in a town not to far from me. The town is called Bracebridge in Ontario Canada, and the dam is perfectly fine. There was a year with an unusual amount of rain and it sort of flew over the top. The dam isnt as high as it looks, and is built ontop of a rock outcrop that creates a lot of whitewater. It's aesthetically the nicest dam I have seen, but most certainly did not fail. Normally you can walk across the top to a park on the other side, but that year they just closed the top off.
I literally just visited that yesterday!
I don't think he ever actually insinuated that it had "failed" in any way. At the start of the video he very obviously sarcastically joked that it was "collapsing", but that was an attempt to jokingly provide the reaction of an average person when they did the measurement and it showed that the concrete had moved. Non-engineers probably generally assume that concrete structures don't move, so they would be a bit alarmed until someone explained what was happening, which is why that part was scripted into the video. This is meant for the general public, so if you are particularly knowledgeable about the subject don't get your panties in a bunch over them trying to make things a bit more entertaining/relatable for the layman.
President ofAustria:
So you're telling me Hamster wants to submerge a drum on our massive dam.
Producers: YES
President: fuck it, send in the special forces. Top priority at all cost. Send in the ninja squad.
Fun fact: Austrias chancellor is called Kurz (German word for short)
@@fabiank485 Men of a feather then
"The dam collapsing, get out and save yourself"
You feel the heaviness in his voice , damn
I've been searching for full video for more than 2 yrs just for the sake of these few minutes.
Thank you so much Quest tv for uploading.
Clarksonnnnnnnnnnnnnnnnnnnnnn!
No
@@kingkong8122 yes
Where’s my roof!!
Hhhhhhhh
Anwarrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!
I love the engineering explained by the experts to Richard lol. It's good for a dummy like me.
They should have send this to Clarkson before his farm project
Yeah Clarkson wasn't really good at building his dam
Excellent video, very well explained!
Hydro-electric is my favorite clean and green energy. Water is liquid gold, we need to save every drop that we can.
True, but without good downstream relocation and environmental risk assessment it can become catastrophic when those liquid gold turns into man-made tsunami
im not the biggest fan. alot of dams ruin entire villages and stuff like that like in china they have a dam that blocks water for other countries
@@JortNNL yeah well but thats just china doing its thing
Love these docs
0:51 He's not measuring correctly. Anybody noticed?
10 months late, but yes.
I use one of those things daily. He was measuring using the cut-out at the base of the prongs.
Of all the mistakes you can make using a caliper, that's got to be the dumbest...
@@Bird_Dog00 not entirely sure, maybe they actually use the callipers that way. (Like always measuring it that way…)
It would still be stupid.
But tbh he likely just did it wrong
@@010falcon That cuttout has only one purpose: It allows you to measure over a freshly machined edge without having to deburr it first. The cuttout leaves room for the burr so it doesn't affect the measurment.
No-one ever uses it to masure anything.
That's Bracebridge Ontario at 5:11. Our dam sucks, recognized it right away
Hammond have you ever measured something with calipers that's not the way to do it
Why so condescending?
@@aeiproject close to the scale there are small gaps for idk what reason so you can't measure accurately if you're close to the scale. You have to go about 3-5mm away front he scale to get a accurate value
I was thinking the exact same thing!
@@ptrjnsn5719 they are very usefull when you have something like a cube you just machines and want to measure accuratly without deburring the cutouts enable you to measure it without measuring the hight of th nur you would remove later or before
Well I just lmao when he says "your dam is leaking"
Anyone else keep watching this Hammond clips from this channel?
I think we can use ram pumps to solve the energy crisis. First we build a hollow cylindrical tower out at sea, to a depth of say 1100m. The tower is open to the air at the top and has a sealed base at the bottom. We drill a hole about 20m below the surface and feed water into the tower. The water falls down a pipe for about 200m where it powers a turbine that is connected to an electricity generator. We collect the water and drop it down a pipe for another 200m to another turbine. We do this twice more until we are getting electricity from four generators.
We then drop the water another 200m to power a turbine which drives a cog that is geared to turn a disc at the base of the tower. The waste water from the last turbine starts to collect at the bottom of the tower creating a shallow reservoir that we need to pump out.
The rotating disc at the base of the tower has cams along its edge. These cams are used to push pistons outwards. These pistons are in cylinders built into the wall in a circular formation. The cylinders are sealed at the interior side apart from where a piston rod enters to push the piston outward. The outside of the piston head is exposed to the deep sea water.
The cam will push the piston outward against the high pressure deep sea water. An inlet pipe will take water from our shallow reservoir which will be pulled into the space created in the cylinder, behind the piston head. When the cam releases the piston, the low pressure water inside the cylinder will be the only thing pushing the piston out against the high pressure deep sea water.
This is when the system acts as a ram pump.
The piston will be forced inward and will force the low pressure water back out through the inlet pipe toward the reservoir. The inlet pipe will now act the same as a waste pipe in a ram pump and the flowing water will shut a waste valve. The remaining water in the cylinder will be forced through a check valve into a pipe and upwards to the surface.
The larger the diameter of the tower, the more cylinders that can be built into the wall at the base of the tower.
I realise that the ram pump cylinder will pump more of its water back into the reservoir than it sends to the surface but we can always add more cylinders to the system. We can even put another layer of cylinders above the original ones as ram pumps still work underneath shallow water.
I think we should be able to pump water upwards at the same rate that it falls into the bottom of the tower and so keep the reservoir nice and shallow.
Now, if I understand the maths correctly, we might only be able to pump the water near to the surface. In that case, we can pump the water into a reservoir tank (inside the tower) and use the electricity generated by the first turbine to pump out the tank.
This will leave us with 3 generators worth of electricity for every tower built.
Would this work? Everyone, please comment.
That sounds genius, design and patent it
No it would not. A closed system cannot produce energy. Simple physics sadly.
We might able to use such a system to store energy, but there are cheaper alternatives
@@010falcon how is this a closed system?
@@crankfwd8209 The amount of energy consumed by the rotating disc would be very high compared to the output of one turbine. I believe you would need to use 100% of the energy of the falling water to push the water 100% of the way back up. Think of the deep water pressure behind the pistons as a spring. When you compress the spring it stores energy, and when relaxed you can recover the same amount of energy (ignoring losses). So the energy required to actuate the pump must match the amount of energy in the falling water. If it is an open system (taking in water from the open ocean and pumping water back out at the surface) it will slowly fill up with water as the pumping rate will be insufficient to clear the reservoir and a closed system (output of the pumps is the only water fed to the top of the tower) won't generate enough power to keep the water flowing in the closed loop.
Otherwise you could simply use the water pressure behind any hydroelectric dam's wall to push the water back to the top after it passed through the turbines, creating a perpetual motion machine. We would already have infinite clean power if it worked.
@@GrantE90 yes, I see what you mean. I was thinking of using a pointed, conical shape on the side of the piston that is pushed into the deep water. When all the way out, it would 'unlock' and form a flat disc that the deep water pressure would push against, to force the piston back in. That way it would use less energy pushing out than it gains from being pushed back in.
4:59 Oh, there it is! I wondered what happened to the beginning part.
That damn is keepin the wootah in check.
Look! It's the titanic sub!!
Please be careful. Those Nijas are crafty.
Is there a part 2?
Where can we watch the Full video?
I hope we still have enough smart people who will study engineering in the future. When I look around my city I really doubt it... 2024
What?? No huge blast of water??? Ripped off!!!
Why it's stops in the most interesting moment of the vid
Why do you have a but plug hammond? 5:55
0:52 what not use a laser measure with some kind of alarm?
Very cool and interesting
Damn i live there
1:20 I hope it continues on breathing thing if it sneeze who knows what have will happen?
Today on BIG let’s explore Jeremy’s gut
First impressions? IT’S VAAST
it is not just the power of water but gravity too.
Why don't they measure all this with sensors instead of old fashioned manual instruments?
Doesn't rely on software or a permanent electrical supply to function correctly, thus making it more reliable in the long run
Also they have to do visual inspections of the material itself all the time, looking for cracks, discoloration, rust and water. Since well trained engineers have to run through their regulary anyway it makes no sense to automate something as simple as taking the distance on such a defined spot once a week or so. A sensor network capable to replace enough of the engineers tasks to give a worthwhile advantage would become very complex (also expensive) and by that create a ton more possible failures.
With infrastructure you should try to reduce the number of possible failures.
when you consider that the giant dam moves like 14cm some hightech sensors would be overkill and also would likely fail, because you cant keep a dam dry and clean as we see in the video. a wet enviroment is really harsh on most electronics and you would either pay premium price for waterproof electronics or you need to replace the sensors every 2 years.
It’s a combination normally. They probably have strain gauges (cracks), piezometers (pressure), tilt meters etc. But these will be calibrated with human readings (ie weekly / monthly /yearly?). It’s probably legislated that someone has to physically inspect the dam about 3 times a week (but probably not an engineer).
5:41 Hammonds looking like he can't understand the guy accent
Dammm thats crazy
6:48 any ideas what is the name of the music track playing ?
Yes! Darude Sandstorm

"A pendulum"
SHIT
ughh, hate the fact that the video is10mins only😑

Do a video about GERD
Would be some video that!
Very good
Dam(n)!
‘That’s quite good, if you do it twice it’s perfect’…. The most German saying I’ve ever heard hah
Yeay
What if the dams breaks what will it look like on the other side like how high?

Scary
What would fish say if they hit a wall?
so this is what happened to titan huh
Not the fat Ninja!
Morgan Freedman vs. Richard Hammond. Who's with me?
Where is the ending scene? I am truly disappointed in you, Hammond!
czcams.com/video/Yrd3748ggLE/video.html&ab_channel=DiscoveryUK
Why not use a laser instead of a pendulum?
I think it's because lasers could tilt even if they are held tight. A very very small tilt could cause a huge measuring difference.
@@EmptyNullified That and a pendulum doesn't stop measuring because some electronic component that's no longer made quit working knocking the thing out of service until the whole thing can be replaced.

Hammond getting old
Refreshing to watch something educational and professional on youtube.
So much crap on here now, scrolling for good content is getting tough.
Sad fact is lots of brainless youtube creaters with garbage content make more money than the highly qualified engineer on this video☹️
