The Wheel Of Fortune

Guest Post by Willis Eschenbach

Due to good fortune and the WUWT readership, we got the chance to not only see the Falkirk Wheel, but to take a ride on it … what a marvelous piece of Scottish engineering. No wonder the engineer on the Starship Enterprise was “Scotty” … here’s the wheel, on a lovely day of rain and sun, but mostly rain. Or what is known as “un-made whisky”, as I’m told rain is called locally:

falkirk wheetThe wheel rotates to move boats up and down, in lieu of a system of locks, to overcome the difference in height between two canals above and below. When you’ve been moved up from the bottom to the top, you are looking out along an elevated waterway that you can see below:

falkirk wheel 2

We didn’t go far on the canal, just through the tunnel and back. The gorgeous ex-fiancée and I take care of her father, who is 85 and legally blind. We’re always looking for things that he can do, and so we were graciously given a very short ride on a boat that is used to carry disabled people along the canals, so that they can be safely out and moving in the fresh air. It would be perfect for the old man, he loves the water but has trouble on the ocean, so we’ll see if we can find something equivalent back in the States.

The boat is one of ten that is operated by a charity called the “Seagull Trust Cruises”. I have been amazed by the amount and extent of work that is done by various charities in the UK. Many things that are done (poorly) by the government in the US are done, and done well, by the charities in the UK. For example, the Seagull Trust Cruises operates totally on public donations, and is staffed entirely by volunteers … and they’ve given free rides to over a million disabled people to date. What a wonderful gift for someone cooped up in a nursing home, or homebound for some chronic medical problem, to be able to take a canal cruise.

So I put £20 into the charity right there on the spot, and if anyone else is so inclined, their website is here, it’s a good cause. They’re set up to take people on wheelchairs, and every penny of the money goes to the actual operating expenses—no one, from the highest to the lowest, takes any money at all for their time.

The engineering on the Falkirk Wheel is so well-balanced that it only takes about the amount of energy needed to toast three slices of toast to rotate the wheel by a half turn, boats, water and all … it’s all computer controlled, and if the water levels in the two chambers are different by more than 75 mm (3″), the whole thing stops. Here’s a view from the top of the wheel, just prior to starting back down:

falkirk wheel 3And here are the gears that make it all go round …

falkirk wheel gears

From there, an old sea-dog who reads WUWT took us on a tour of the “kirk”, or church, for which Falkirk is named. First, though, we stopped at the Antonine wall. It served the same purpose as the better-known Hadrians wall, regulating commerce. Unlike Hadrian’s Wall, however, it was built of turf, and has since disappeared. All that is left are the trench that was excavated to provide the turf for the wall and increase its height, and the heap of earth on the left that is where the wall once stood:

antonine wallI was irresistibly reminded of Matsuo Basho’s haiku, written on a battlefield that was already ancient in the 1600’s …

Of stalwart warriors’ spendid dreams

The aftermath …

We were then taken on a guided tour of the Falkirk church. “Falkirk” means “spotted church”, because the original church (built in 36,000BC or some such date) was built with stones of different colors. The church feed lunch every day to the homeless, and the cost of that is recovered by selling the same meals to anyone who comes in … so we started out with lunch at the church. Like the Seagull Trust, the restaurant is completely staffed by volunteers.

Inside, the church is very unusual, because it’s rounded. Unlike most churches, it felt well-worn and well-loved. The best part of the tour, though, was we went up into the belfry.

falkirk bells

I’ve never been up in an actual belfry before, in the US churches generally have loudspeakers … the old sea-dog said bells were a gift from the Dollar family of San Francisco … “The owners of the Dollar Steamship Lines?” I asked, because that name is very familiar on the West Coast. Yes, I was told, the family came from Falkirk, and they had the bells made in the US and shipped back to the old country after they’d made their fortune.

And wonder of wonders, I was invited to play the bells! Rather than subject the entire city to a novice, I just played a few notes … I’ve never, ever played an acoustic instrument of that power, it was astonishing. The only thing I can compare it to, which some may understand, is driving a D10 Caterpillar dozer … raw unbridled strength at my fingertips.

falkirk bells II

Parts of the church are made of sandstone … and it is so old that the very stones themselves have been worn away, not by people or by traffic, but by the rain … where I grew up, that only happens to mountains. The folks of Falkirk appear to be harder than their sandstone, however, if this plaque near the church is accurate …

falkirk mottoThe old sea-dog had graciously invited us to spend the night at his home, and on the way there we stopped at the Carron Iron Works … or more accurately, a monument to the former Carron works, cheaper ironwork from the Japanese drove them out of business. There I learned that a “carronade”, which is a small cannon which I’d read about in many histories of the period, was named after the Carron works. It’s a lethal affair designed to shoot “grape-shot” at infantry, basically a shotgun on steroids.

All that’s left of the works now are a couple of cannons and carronades … the cannon in the background is one of two surviving cannons from the battle of Waterloo, the other is to the left of it just out of the picture.

falkirk carronadeThe Carron Iron Works was also the company that made the first steam boiler for James Watt, a part of which is mounted in the wall of the monument:

falkirk watt's boiler“Stalwart warriors’ splendid dreams” indeed …

We had a lovely evening with the old sea-dog and his good lady, listening to stories of life at sea as recounted by he and his wife, who had accompanied him around the world, and tales of battles in Falkirk won and lost. I can’t thank them enough for their hospitality and the insights into Scotland and life in the north.

The next day we rolled on to Edinburgh, where we are now … but that’s a story for another day, we’re off to see Mary King’s Close.

My best to all, more to come,

Willis,
Great job and keep up the good work- many thanks!
My grandfather was quick to point out our Highlander Scot heritage and if you’re around some of our old Clan Donnachaidh stomping grounds, I hear that Loch Duhn Alastair offers some of the best wild trout fishing available.
Of course, since I’m American, one might guess that there may be other nationalities in my heritage, as well.

The Falkirk wheel replaced a series of 11 earlier locks in the canal that had fallen into disuse. Total level change is 24 meters. The beauty of it is that according to Archimedes’ principle it does not matter what the weights of the boats on the upper and lower buckets are. As long as the water level is identical in both buckets the total weight (bucket + boats) on each arm will be identical, and therefore the wheel is balanced. It is only necessary to overcome bearing friction to rotate the wheel. In principle buckets of any size will work, but eventually bearings will fail, establishing the practical limits of the design.

I love to see where people have been doing the same thing for hundreds of years, until somebody does it so differently and with elegance. Mankind is not even close to discovering/inventing all that will be.

Umm, that’s not Archimedes’ Principle.
The relative water levels of the chambers are set by the waterways, and are near-identical by design of the wheel as those are the levels the chambers are filled at. They don’t change unless the level of one or more waterways change.

Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.
— Archimedes of Syracuse

Displace a pound of water, buoyancy supplies an upward force of one pound.
Hopefully you can see there could be a concrete barge in one chamber, a small rowboat in the other, the water level relative to the chambers would be the same in both while the total weights are not the same.

OK. Then do the math with me – I’m not getting those results.
Two chambers, each carrying 1000 tons of water, both empty of ships, both at the same height of water. They weigh the same, if both are assumed in the same gravitation field at the same distance from that gravitation field.
I float in a 1 ton dry weight rowboat into the first, and I float a 100 ton dry weight concrete barge into the second. Now, which has a higher height of water, and what is the final balanced weight in each?

RACookPE1978 on September 14, 2013 at 7:39 pm:
That’s a good approach, if you are dropping the vessels into containers from above by crane.
But the chambers are open when loading, any water displaced merely sloshes back into its respective waterway. 100 ton barge in one, 1 ton rowboat (which sounds freaking enormous, please do a perspective check before tossing out numbers like that) in the other, the water levels when the chambers are closed will still be that of their respective waterways.
You may now proceed to *foreheadslap* or *facepalm*, your choice, and the utterance of “Duh!” or “D’oh!”, your choice.

Nah. A 2000 lb boat is small, compared to most in the southern US bass lakes. 8<)
But you have begun exactly as should be done: Drive both boats into the two containers. Let the water equalize in both with the assumed upper and lower canal levels. Volume canal much, than volume of container, right? Now, what is the weight of both containers?

Another wonderful travelogue by the Master! Please, keep ’em coming.
As I am genetically half Scots [and half Smokey!] I immensely enjoyed reading about the melding of our respective cultures. We are really the same, culturally, despite minor accent differences.
I believe strongly that the ingenuity displayed by the world’s English speakers is the real reason that led directly to the landing on the moon, with many other triumphs along the way, such as the Falkirk ‘wheel of fortune’.
The Chinese never did it, nor did the East Indians, nor the Russians, nor the Incas. Amerinds never even invented the wheel [I am certain that I am stepping on plenty of toes here — but now we are all Westerners, so we’re on the same team]. Not that there is anything wrong with any of them! ☺ It’s hard to argue with success, no? Even if it is politically incorrect.
History is my real passion. We are descendants of truly great people; solitary inventors who had an idea, and then made it happen; twenty years to invent a clock that was accurate enough to determine Longitude, for example.
Please keep the stories coming, Willis. You’re one in a million. When I win the Lotto grand prize, I will subsidize your travels just for the pleasure of reading about your historical explanations!

Sorry for the delayed response. Working on a new back deck railing all day then on the porch sharing some wine with some friends.

The displacement of the lower bucket changes as it enters and exits the water. Granted, the sine of that angle is near zero, but it still takes a torque to submerge the bucket. Or am I missing something?

Would it though?
There are certainly minor friction (water resistance to movement) losses as the container rolls into the water, but the velocity is slow slow (foot per second range), I would think those are minor. And the steel and aluminum of the container below final water level would displace the water in the lower bay (entrance channel) as it rolls down, but that would reduce the force on the lever arm holding the channel as the midpoint, right? In midair, the lever arm has to hold everything, but there is less weight as the steel goes underwater after the container goes down since some of the steel is displacing water not air.

Gravity still works, what a relief!
Excuse me, but what exactly does this tour series through England, Ireland, Wales, and Scotland have to do with Climate Change/Heating/Cooling/Whatever?
While I think Mr. Willis Eschenbach’s stories are of some entertainment/interest value, they really are way off topic for this site, aren’t they? Better suited to a tour through the UK series…
Or is the climate watch series of stories so slow now that that travel-logs are of importance to the folks that follow WUWT?
I thought there were topics of more specific interest relating to the controversy over Anthropomorphic heating/cooling/CO2 than this exploratorium to examine.
Back to waiting for some real controversy…

That is no surprise to me. As a Brit who has studied history, the Scottish people have been streets ahead of the rest of the UK. If I( want to find a fellow englishman I need to delve very deeply and even going back in time you have to look passed the money. Steam Engines and trains are a classic example of the truth being hidden and the credit given to others.

If you want a real treat visit the far Northwest coast of Scotland – between Kyle of Lochalsh and Durness. I’ve been in lots of places all around the world and have yet to find anywhere to compare with the beauty of that coast. It is remote so very few people visit.

No, they are very on topic. The top of each WUWT page is labelled

Commentary on puzzling things in life, nature, science weather, climate change, technology, and recent news by Anth*ny W*tts.

The above article mentions most of those subjects and is approved by Anth*ny W*tts because he has allowed it on his blog.
The purpose of your post is clear from this of its statements

I thought there were topics of more specific interest relating to the controversy over Anthropomorphic heating/cooling/CO2 than this exploratorium to examine.

Mockey Mouse is anthropomorphic.
Warmunists claim CO2 is inducing climate change which is anthropogenic.
Anybody who knows anything about the climate controversy knows that.
Clearly, you don’t know what you are talking about and have posted to denigrate.
If you don’t want to read an article then don’t, and keep your ignorant opinions to yourself because they may spoil enjoyment of the article by other people.

richardscourteney, you beat me to it. I was just checking the exact wording on the heading of WUWT.
As the wife of a retired lifeboatman I echo your earlier sentiments regarding the RNLI.

September 15, 2013 2:01 am

Jaymam; the points don’t actually go into the water, they go down into a dry sump under the Wheel.
Alan Watt; “Gondolas”, not “buckets”. Good grief, man, where is your sense of romanticism?
dbstealey; actually TFW is based on a Russian design from 1911 which was never built because the First World War, and then The Revolution, happened.

September 15, 2013 2:06 am

Dan and RACook; see above. The Gondola sides are never immersed.

Dear Willis
Thank you for another great post which educates, informs and entertains? Are you going to reveal who the old sea dog is or do I have to submit a FOI request 🙂
I hope you will visit the land of my fathers?
To Andrew above who seems to take pleasure in denigrating the English contribution to science, engineering and invention, I suggest you do some more research and come back and apologise?

Where would be without the wheel ?

I’ve been on the Falkirk Wheel and I loved it. One of my favourite stories about it is that they had to extend the canal to the location of the wheel. They also had to repair the existing canal, clear it of garbage and reconnect it where it had been blocked (often by new roads).
Anyway, they then planted new vegetation to stabilise and beautify the canal banks. They needed to protect the new plants from foraging by rabbits and other animals. They wanted something to protect the plants from animals but allow sunlight and rain onto the plants.
So what did they use?
Shopping trolleys. There were enough shopping trolleys dumped in the canals to recover and use as plant protection.
