Meet the world's one-of-a-kind ENORMO barge-bowling bridge of Falkirk Proving it's not just the Victorians who can make huge structures in steel, the Falkirk Wheel can lift six canal boats 25 metres in one go, moving them from one waterway to another. The Forth & Clyde Canal, running across central Scotland, used to be connected to the Union Canal, linking Glasgow to Edinburgh via a stairway of …

That reminds me of the picture I saw of a small child on the telephone (with one hand doing a face-palm) and the caption "No, grandma, double-click on the Internet Explorer icon..."

GBP222,458.00 though they will probably give you a discount up there in the North...
I've been on this by small ship quite a few times - it's two massive interconnected bathtubs running one and a half kilometres up and down a hill. Basically an episode of "Last of the Summer Wine" on steroids

And we have this one too in Belgium: http://en.wikipedia.org/wiki/Str%C3%A9py-Thieu_boat_lift
" It is the tallest boat lift in the world". And maybe the ugliest too. And it's not engineered by the Scottish: http://www.canal-du-centre.be/Presse/En/20000700_avarie.html
Thereagain, the European canals and their ships are much larger than those in the UK. The Scottish one certainly wins on style, but given that most of the canal boats over here are over 50M long and as wide as half a dozen British canal boats, that's without taking into account the hulks they push around in front of them, they wouldn't have a cat in hells chance of fitting into the lift - well, they'd never get to the lift, because the wouldn't fit in the canal. :-P
Price tag on the Belgian thing is, um, maybe 7-8 times what the Falkirk thing cost.
BBC radio has been down into the Crossrail tunnel works in London recently and having a whale of a time. But when it's finished it will be just trains really. Not that that isn't fun. I think the feature has been included in several programmes including World Service radio's "Science Hour" last weekend, or maybe previously.
Wikipedia page for Crossrail claims to have a picture of the "portal" to get into it, but it doesn't look like for instance the Star-Gate, which I think is a missed opportunity. Maybe they are going to put that in later, like Platform 9¾ at King's Cross. (Actually that's been done.)
Projects like this are great things. I think it is sad that the last generation (longer in some places) has been all about lowering costs and increasing efficiencies, two absolutely uninteresting things, and they've managed to make everything more expensive and less efficient. There is never enough money for governments and soooo much money is wasted trying to save a dollar.
There should be more large engineering projects in today's world, if for no other reason than to show the future that we weren't idiots and we also had a handle on technology. As it stands right now our civilization looks like it hasn't accomplished much of anything of storybook/legendary status since WWII (with rare exceptions, like this).
We've let the bean counters take control and that, oddly enough, never pays off for anyone: (Insert price/value and accountant colloquialism here). Down with accountants!
"for no other reason than to show the future that we weren't idiots and we also had a handle on technology"
Are you sure about that? Don't you find that mobile phone thing in your pocket, not to mention the technology and infrastructure it connects to, just a little bit impressive?? Admittedly it's not BIG, but it is bloody well clever stuff, and that's just to name one. For me this generation's achievements are in the incredibly SMALL, but also even more in the DISPOSABLE: not only making something incredibly clever, but perfecting the manufacturing to make it so cheaply that it becomes an everyday item that you don't even think about.
I agree there has been some significant accomplishments for sure, but if you look back at previous cultures their most recognized legacies are their large engineering projects. Either through the fact they still exist or through story and legend.
The little things are of interest primarily to anthropologists: Day to day habits and possessions. Even then there's often no consensus on those things, just a lot of well educated guesses. Computing in all its current forms will be interesting to the future the same way that old brass cash registers, telegraphs, mimeographs, and printing presses are interesting. Current computing will be an interesting sidebar to a subset of the population, a step in communication technology, not an icon future cultures will identify with us.
This April I ran length of the canal from Glasgow to Edinburgh (55miles) for fun (yes for fun), which is a yearly race. Its very pretty and amazing with the wheel being about 20 miles in. Cycling is popular with railway stations scattered along the way. The tunnel shortly after the wheel is also fantastic and worth a visit.

If you've got the manpower, tools and budget, hand torqued fasteners are always a superior option. Even the best powered drivers leave a lot to be desired in the accuracy department. For instance the $8,000 electric drivers we use for production assemblies show ~8% variance over a $3,000 old school manual torque wrench. Powered drivers also go out of calibration faster.
As far as this project goes though you are correct in that this is likely superfluous. Unless I'm really, really underestimating the speeds of this thing it probably doesn't create the harmonics necessary to allow a few out of spec fasteners to cause failure or accelerated wear.
But I suspect it needs a surprising amount of late 20th century engineering know how (CAD/FAE high quality steels and the ability to cast and/or weld very big parts) to actually deliver it.
But it's one hell of an achievement. It's practical, highly energy efficient (from the number quoted to move those kinds of mass) and graceful
They probably could, but it would have involved a lot of small children inside the the structure, holding the 'dolly' as someone outside riveted it with a steam hammer. "Loud" would not begin to describe the noise!
See also the films of building a riveted ship, where they throw the red hot rivet from one to another.
Look also at the Foxton Inclined Plane.

What's all this fuss about "efficiency"? Make the arm span (centre to centre) a smidge shorter than the distance between the two water levels, then mount the thing at an axis level half a smidge above the midpoint between the water levels. Bob's you're uncle: The whole contraption should self power, generate enough surplus to drive the docking mechanism and perhaps a wee bit over to light the visitor centre. Assuming of course that the upper waterway is adequately fed, which, as the wheel was preceded by locks, it is.
Definitely not a Scottish design. No self respecting Scot would ever have missed that.

You'd have to mount the gondolas a smidge offset from the centre line as well, so that it was self-starting, and I'm not sure the generator would apply enough drag to avoid an accelerating splashdown on each half-rotation. Perfect balance, with a tiny amount of power to start and stop, is probably easier to manage than the braking/damping assembly necessary to keep a smooth self-powered descent. That was one of the problems with the Anderton lift, corrosion of the piston arms gradually eroded the seal around the hydraulics, and it made fine control increasingly difficult.
> I'm not sure the generator would apply enough drag to avoid an accelerating splashdown
Quite sure that even the Victorians had regulators for that sort of thing... I'm imagining lots of well greased gear wheels and enormous brass balls spinning on the ends of arms: Perhaps they could have weighted them with visiting children instead of that costly brass (for a small fee - natch) and entertained the visitors into the bargain.
The more I think about it, the more certain I become that the Scottish would have done a much better job designing the thing!
when I went several years ago, the tour guides explained that one of the major advantages over the locks is that there isn't any water loss involved. These are after all, canals, and not rivers.
Really cool to see in person. I could have sat watching the giant planetary gears spin around for hours.
Kayak certainly. A small charge for a short term canal license for an unpowered craft, and I believe the wheel is then free. Go up and down as many times as you like.
Seriously, the tourist trip is not superflous. Get a seat right at the front for an amazing view on the descent.
