Me great interest in the mechanics of the past stems from when I were like our Jack - quite a small boy - | 0:00:18 | 0:00:25 | |
going along the canal from Bolton to Bury, | 0:00:25 | 0:00:29 | |
and seeing the remains of old coal mines and cotton mill engine houses. Some were still working. | 0:00:29 | 0:00:35 | |
That's really why I've created all this lot here in me back yard. | 0:00:35 | 0:00:40 | |
It's sort of a vain attempt to hang onto childhood memories, I suppose. | 0:00:40 | 0:00:45 | |
This is the Bancroft Mill Engine Trust, | 0:01:13 | 0:01:17 | |
and up until 1978, there was a big weaving shed out the back. | 0:01:17 | 0:01:22 | |
This is all that remains of it - | 0:01:22 | 0:01:25 | |
the engine, the chimney and the boiler. | 0:01:25 | 0:01:29 | |
And it's situated at Barnoldswick, on the Lancashire and Yorkshire border. | 0:01:29 | 0:01:35 | |
They've turned it now into an industrial heritage centre where everybody can come | 0:01:35 | 0:01:41 | |
and see the original mill engine in steam. | 0:01:41 | 0:01:44 | |
There used to be loads of engines like this, where I come from. | 0:01:44 | 0:01:49 | |
Every coal mine and spinning mill had one. Alas, they've all gone now. | 0:01:49 | 0:01:55 | |
This is the Bolton to Bury canal, | 0:01:56 | 0:01:59 | |
and, as a small boy, I used to come along here with me father on me bicycle. | 0:01:59 | 0:02:06 | |
And, to me, it were quite an exciting world, you know. | 0:02:06 | 0:02:10 | |
There were coal mines and cotton mills, and wonderful things like inclined railways. | 0:02:10 | 0:02:17 | |
Really interesting stuff, if you like industrial archaeology. | 0:02:17 | 0:02:22 | |
Like this crane. The first time I saw it, it were almost complete, | 0:02:22 | 0:02:27 | |
and now, of course, there's hardly anything left of it. | 0:02:27 | 0:02:31 | |
The boats used to pull up here and they had boxes in, full of coal. | 0:02:31 | 0:02:37 | |
And the crane used to lift one out and swing round and drop it down into the paper mill. | 0:02:37 | 0:02:44 | |
Britain was the birthplace of the Industrial Revolution, | 0:02:44 | 0:02:49 | |
and although machinery like this is now sadly decaying, | 0:02:49 | 0:02:54 | |
for more than 200 years, we led the world in harnessing the power of coal, water and steam, | 0:02:54 | 0:03:02 | |
to drive the heavy machinery that made mass production possible. | 0:03:02 | 0:03:07 | |
It's an era that I only saw the end of, but I wish I'd have seen more of it. | 0:03:07 | 0:03:14 | |
It's only within the last 40-odd years | 0:03:14 | 0:03:18 | |
that our great industries have disappeared. | 0:03:18 | 0:03:22 | |
In the '60s, the skylines of Lancashire mill towns | 0:03:24 | 0:03:28 | |
still bristled with chimneys. | 0:03:28 | 0:03:31 | |
And the view of Sheffield by night | 0:03:31 | 0:03:34 | |
was something like Dante's Inferno, | 0:03:34 | 0:03:37 | |
with the glow of the furnaces lighting the sky | 0:03:37 | 0:03:42 | |
and rivers of glowing white-hot molten steel flowing through the smoke. | 0:03:42 | 0:03:47 | |
As the mines, the mills, the factories and the steelworks | 0:03:47 | 0:03:53 | |
and the engineering works closed, the demolition men moved in, | 0:03:53 | 0:03:58 | |
and machinery that had made Britain the workshop of the world came under the wrecker's hammer. | 0:03:58 | 0:04:04 | |
Scrap merchants became wealthy, as they stripped brass, etc, from the engines. | 0:04:04 | 0:04:10 | |
Most people didn't care about what was going on, | 0:04:10 | 0:04:15 | |
but a few realised that if something wasn't done about it, | 0:04:15 | 0:04:19 | |
there'd be nothing left to show for an important part of our history. | 0:04:19 | 0:04:25 | |
People started to restore old engines, and steam locomotive preservation societies appeared. | 0:04:25 | 0:04:33 | |
30mph. Ha-ha! | 0:04:33 | 0:04:35 | |
Thanks to the interest and dedication of these people, | 0:04:37 | 0:04:41 | |
a small part of our industrial story has been preserved for future generations. | 0:04:41 | 0:04:48 | |
I'm off now on a tour of Britain, in search of our industrial past, | 0:04:52 | 0:04:57 | |
and the people who've restored a great deal of it, | 0:04:57 | 0:05:02 | |
to save it from the scrap man. | 0:05:02 | 0:05:04 | |
And so future generations can see what a wonderful race Britain was in the engineering field. | 0:05:04 | 0:05:11 | |
My interest is mainly in steam, | 0:05:11 | 0:05:14 | |
but the earliest form of power is one that's still with us. | 0:05:14 | 0:05:19 | |
I went to Shropshire to meet a man | 0:05:19 | 0:05:22 | |
who's taken on a job in his garden, bigger than anything in mine. | 0:05:22 | 0:05:27 | |
-It was in a sad way. No machinery left. -No. | 0:05:27 | 0:05:31 | |
That had fallen down, some years ago, and been sold for scrap. | 0:05:31 | 0:05:35 | |
Peter Lewis has spent the last 16 years restoring this windmill, round the back of his house. | 0:05:35 | 0:05:43 | |
The windmill that Peter's restoring is a tower mill. | 0:05:43 | 0:05:48 | |
The sails are attached to the cap at the top. | 0:05:48 | 0:05:52 | |
-This bit makes it face into the wind? -24 hours a day it goes round. | 0:05:52 | 0:05:57 | |
-Keeps it facing the wind. -Really carpentry on a grand scale, this. | 0:05:57 | 0:06:02 | |
Great lumps a foot square and two foot square... | 0:06:02 | 0:06:06 | |
I believe you can disconnect it here and make it go round by hand. | 0:06:06 | 0:06:12 | |
-That's right. -In case of disaster. -You need a means of coping if the fan goes wrong. | 0:06:12 | 0:06:18 | |
-High technology(!) -Well, it works. | 0:06:18 | 0:06:21 | |
-Necessity is the mother of invention. -Put the handle on... | 0:06:21 | 0:06:25 | |
-And off we go. -Roundabout job. | 0:06:25 | 0:06:28 | |
Free tour. | 0:06:28 | 0:06:31 | |
You can see the jolly miller up here in his smock. | 0:06:31 | 0:06:37 | |
-Thunder and lightning and a force 10 gale. -Aye. Yeah. | 0:06:37 | 0:06:42 | |
Tower mills aren't the only kind of windmill. | 0:06:44 | 0:06:48 | |
My travels took me to East Anglia where I found the post mill. | 0:06:48 | 0:06:53 | |
If you wanna see a good example of a post mill | 0:06:53 | 0:06:57 | |
East Suffolk is the place to come. | 0:06:57 | 0:06:59 | |
East Suffolk post mills were said to be amongst the best in the world. | 0:06:59 | 0:07:05 | |
Saxtead Green has a wonderful example of one. | 0:07:05 | 0:07:08 | |
The fan tail on the post mill is much lower | 0:07:08 | 0:07:12 | |
because it's not just the top that turns to face the sails into the wind, but the whole windmill. | 0:07:12 | 0:07:20 | |
So you can turn the building round. | 0:07:20 | 0:07:23 | |
If you've no wind, the corn grinding comes to a halt. | 0:07:23 | 0:07:27 | |
-Hello, Jonathan. -Hello, Fred. Nice to see you. | 0:07:27 | 0:07:31 | |
What operation are you performing? | 0:07:31 | 0:07:34 | |
-The old mill has got tail-winded. -Yeah. -Which it very rarely does. | 0:07:34 | 0:07:39 | |
-That means it wasn't facing the wind properly. -Yeah. -So we give it a helping hand. | 0:07:39 | 0:07:46 | |
-To get it into the wind. -Yeah. How many tonnes are you turning? -About 18 tonnes. | 0:07:46 | 0:07:52 | |
There's about 6 tonnes of sails and 2 tonnes of stones in the superstructure. | 0:07:52 | 0:07:59 | |
-D'you want to have a go? -Yeah. | 0:07:59 | 0:08:02 | |
It's quite easy, innit? | 0:08:02 | 0:08:05 | |
Oh, yes. Yes. | 0:08:05 | 0:08:08 | |
We'll be all right when we get to the next parish. | 0:08:08 | 0:08:12 | |
You'd never get 10mph out it. | 0:08:12 | 0:08:15 | |
This has gotta be, really, one of the finest examples | 0:08:30 | 0:08:35 | |
of corn grinding windmill technology. | 0:08:35 | 0:08:38 | |
But, of course, for windmills you need wind. | 0:08:38 | 0:08:44 | |
Water was a more reliable power source. | 0:08:47 | 0:08:51 | |
You can see plenty of examples of working watermills around the country. | 0:08:51 | 0:08:57 | |
Muncaster mill is near Ravenglass. | 0:08:57 | 0:09:00 | |
The miller's wife, Pam, gave me a tour. It has a 13 foot overshot water wheel - | 0:09:00 | 0:09:07 | |
one where the water comes in over the top. | 0:09:07 | 0:09:11 | |
It's connected to cogs in the mill which drive the milling machinery. | 0:09:11 | 0:09:16 | |
-It's amazing how nice and quiet it is. -Because of the wooden cogs. | 0:09:16 | 0:09:21 | |
This is the pit wheel that's attached to the water wheel. | 0:09:21 | 0:09:25 | |
-But the wooden cogs are there so that there won't be any sparks from any metal bits. -Cause fires. | 0:09:25 | 0:09:32 | |
The cogs that drive the millstones are connected to the floor above | 0:09:32 | 0:09:38 | |
where we're actually grinding corn at the moment. | 0:09:38 | 0:09:42 | |
The grain goes in a hopper and that falls into the wooden piece underneath that moves about - a shoe. | 0:09:42 | 0:09:48 | |
-This is the boat-shaped thing underneath. -Yeah. | 0:09:48 | 0:09:52 | |
The grain is slowly drizzled into the centre of the stone, the eye, | 0:09:52 | 0:09:58 | |
by the spindle that's splayed out of it. It's called the damsel. | 0:09:58 | 0:10:03 | |
-Anything that goes down is gravity. Anything that comes up, we need mechanical help. -I know. | 0:10:03 | 0:10:08 | |
-This is the rope from the sack hoist. -Does it work? -It certainly does. Give it a pull. See the sack hoist? | 0:10:08 | 0:10:18 | |
..There it goes. | 0:10:18 | 0:10:21 | |
-Oh. -See it coming up through the trap door? -Yeah, yeah. | 0:10:21 | 0:10:25 | |
Everything you see in a watermill like this is similar to what you find in a windmill. | 0:10:25 | 0:10:32 | |
Up until the 18th century, all we had were these things, | 0:10:32 | 0:10:36 | |
water wheels and windmills. | 0:10:36 | 0:10:39 | |
And then... | 0:10:39 | 0:10:41 | |
this came along. | 0:10:41 | 0:10:44 | |
HORN BLASTS | 0:10:44 | 0:10:47 | |
< Crack a light, Fred! | 0:10:51 | 0:10:54 | |
Not exactly steam railways - they came a bit later. | 0:10:54 | 0:10:58 | |
But the Ravenglass and Eskdale railway runs right past Muncaster mill. | 0:10:58 | 0:11:05 | |
I wasn't gonna let this beautiful little steam train go past without having a ride on it. | 0:11:05 | 0:11:12 | |
..You can keep dry in this engine. | 0:11:12 | 0:11:16 | |
How old is this one? | 0:11:16 | 0:11:19 | |
-Seventy-five this year. -Seventy-five? | 0:11:19 | 0:11:23 | |
ENGINE DROWNS CONVERSATION | 0:11:23 | 0:11:27 | |
Got all the W & J Kirkham's magical lubricators on, that is. | 0:11:35 | 0:11:43 | |
-Made in Bolton, them. Where are they? -Well, they've gone now, but the works is still there. | 0:11:43 | 0:11:49 | |
-Well, there we are, then. -Yes. | 0:11:53 | 0:11:55 | |
-I really enjoyed that. -Good. -Thank you very much. | 0:11:55 | 0:12:00 | |
A lot smoother than a steamroller, that, I can tell you! | 0:12:02 | 0:12:07 | |
The very first steam engines weren't very smooth, either! | 0:12:07 | 0:12:12 | |
They weren't polished, shiny things like this, and didn't go anywhere. | 0:12:12 | 0:12:17 | |
They were much more primitive at first than this. | 0:12:17 | 0:12:21 | |
This wonderful thing behind us | 0:12:31 | 0:12:34 | |
is a working example of the world's first steam engine. | 0:12:34 | 0:12:39 | |
And this is Ian, who is the curator of the Black Country museum, | 0:12:39 | 0:12:45 | |
-who is going to tell me how it works. You are, aren't you? -Yeah. | 0:12:45 | 0:12:49 | |
It's the world's very first recorded steam engine, | 0:12:49 | 0:12:54 | |
built by Thomas Newcomen in 1712, though he didn't build this one. | 0:12:54 | 0:12:59 | |
-He built the original in Dudley. We built this replica 15 years ago to see whether it worked. -Yes. | 0:12:59 | 0:13:06 | |
The original worked for nearly 60 years. We've had this about 15 and it works most of the time. | 0:13:06 | 0:13:13 | |
-This was called a "fire engine" because it doesn't actually use steam pressure. -No. -It uses vacuum. | 0:13:13 | 0:13:20 | |
So you put the steam in the cylinder, | 0:13:20 | 0:13:23 | |
put in the cold water - it creates a vacuum - sucks the piston down. | 0:13:23 | 0:13:28 | |
Get to the bottom, let the steam back in...up and down she goes, pumping water from the coal mines. | 0:13:28 | 0:13:35 | |
It was built for the Dudley estates, to drain water from the mine. Horses and wind power weren't good enough. | 0:13:35 | 0:13:44 | |
The trouble was that the first engines weren't very efficient. | 0:13:45 | 0:13:50 | |
After Mr Newcomen's atmospheric engine, which was basically made of wood, | 0:13:52 | 0:13:59 | |
it weren't until 1765 when a famous Scottish engineer, James Watt, came along, | 0:13:59 | 0:14:06 | |
and did a lot of important things. | 0:14:06 | 0:14:09 | |
He invented the parallel motion at the other end of the beam, | 0:14:09 | 0:14:14 | |
and then he stuck the crank on the other end of the connecting rod | 0:14:14 | 0:14:19 | |
and made a wheel go round. That were the prototype for all the steam engines up till 1860. | 0:14:19 | 0:14:26 | |
The beam engine was the workhorse of the Industrial Revolution. | 0:14:26 | 0:14:31 | |
In its most crude form, it pumped water from mines. | 0:14:31 | 0:14:36 | |
It developed into a reciprocating steam engine, | 0:14:36 | 0:14:40 | |
to power ironworks, textile mills and any sort of factory that needed power. | 0:14:40 | 0:14:47 | |
These days, the only steam engines you come across that actually work | 0:14:57 | 0:15:02 | |
are the ones that have been preserved for posterity to look at. | 0:15:02 | 0:15:07 | |
And here at Llyn Cwellyn near Caernarfon in North Wales, | 0:15:07 | 0:15:12 | |
there's a beautiful steam engine built in 1854. | 0:15:12 | 0:15:16 | |
I initially came here to do up the chimney stack. | 0:15:16 | 0:15:20 | |
And it was such a sad sight - the buildings here. The chimney covered in ivy like a Cornish tin mine. | 0:15:20 | 0:15:28 | |
Holes in the roof, trees growing through windows... | 0:15:28 | 0:15:32 | |
And the steam engine were in a really sad state. | 0:15:32 | 0:15:36 | |
I managed to secure the contract for doing up the steam engine. | 0:15:36 | 0:15:41 | |
I spent roughly 18 months, with two other lads, hard at it. | 0:15:42 | 0:15:47 | |
When I first come through that door, somewhere around 1988, and looked at this thing, | 0:15:48 | 0:15:55 | |
it were in a terrible state - rusted solid. | 0:15:55 | 0:16:00 | |
And it had been vandalised - all the brass bits were gone. | 0:16:00 | 0:16:05 | |
I took it all back home to Bolton and took a shaving off everything and brought it back to reassemble. | 0:16:05 | 0:16:12 | |
This shiny bit here - | 0:16:12 | 0:16:15 | |
we made the fly wheel go round by using an oil engine borrowed from the agricultural college. | 0:16:15 | 0:16:22 | |
And we took a shaving off here. And I shined the big... The crank here. | 0:16:22 | 0:16:28 | |
I don't really know how I did that now! It were like corrugated iron! | 0:16:28 | 0:16:33 | |
And, of course, THIS was the problem, like, the Cornish boiler. | 0:16:33 | 0:16:39 | |
Part of the contract was to jack the thing up and have a look at the bottom. | 0:16:39 | 0:16:46 | |
You could have put your boot through the bottom! | 0:16:46 | 0:16:51 | |
Lovely old thing made in 1854 by Mr D Winton at Caernarfon, | 0:16:51 | 0:16:56 | |
and no doubt brought up the road on horses and cart, back in 1850. | 0:16:56 | 0:17:02 | |
Er... No good. | 0:17:02 | 0:17:04 | |
And down the pub where we stayed, there were a fine body of lads who worked for the Coastguard. | 0:17:04 | 0:17:11 | |
And one of them said, "I know where there's a boiler, | 0:17:11 | 0:17:16 | |
"belonging to Mr Roberts, a pork pie manufacturer." | 0:17:16 | 0:17:20 | |
And to cut a long story short, he gave us the boiler - or gave it to Caernarfon Council, | 0:17:20 | 0:17:26 | |
and we got it up here and tested it and installed it next door. | 0:17:26 | 0:17:31 | |
It's a vertical, cross-tube boiler with 12 cross-tubes, so it's a good steamer. | 0:17:31 | 0:17:38 | |
It's a bit like being on top of a 200-foot chimney up here - the Dorothea quarry in North Wales. | 0:17:44 | 0:17:51 | |
When I came here, a gentleman said, | 0:17:51 | 0:17:54 | |
"I'll show you a wonderful place with all sorts of things waiting to be restored." | 0:17:54 | 0:18:01 | |
Just down there, there's a beautiful Cornish beam engine, | 0:18:01 | 0:18:06 | |
and a shaft 700 feet deep | 0:18:06 | 0:18:09 | |
that pumped the water out of this big hole behind me. | 0:18:09 | 0:18:13 | |
There were once 500 men working down that hole. | 0:18:16 | 0:18:20 | |
In this area alone, up and down the valley, within a mile or so, 2,000 and odd people worked. | 0:18:20 | 0:18:26 | |
Now there's nothing. Just lovely, ruined buildings. | 0:18:26 | 0:18:30 | |
This is the beam engine here that's been here since 1906. | 0:18:52 | 0:18:57 | |
Made by Holman Brothers, Cornwall - a famous engineering company. | 0:18:57 | 0:19:02 | |
It was made initially to pump the water out of the quarry next door, which is 600 feet deep. | 0:19:02 | 0:19:09 | |
It gave up, finally, in 1956, and was replaced by two electric pumps, | 0:19:09 | 0:19:14 | |
which did the job for a quarter of the price. | 0:19:14 | 0:19:18 | |
And now it's patiently waiting for restoration money | 0:19:18 | 0:19:22 | |
to perhaps make it go again some day. | 0:19:22 | 0:19:26 | |
When it's fully restored and working, a beam engine like this is a magnificent sight. | 0:19:30 | 0:19:37 | |
In the days of Queen Victoria, as well as providing industrial power, | 0:19:37 | 0:19:42 | |
these engines started to bring improvements to domestic life. | 0:19:42 | 0:19:47 | |
As the Industrial Revolution progressed and the population grew, the demand for clean water grew too. | 0:19:47 | 0:19:54 | |
Because it was so efficient at pumping water, | 0:19:54 | 0:19:58 | |
the beam engine became the basic working machine of the water industry. | 0:19:58 | 0:20:04 | |
With the building of pumping stations in the 19th century, beam engine technology reached its peak. | 0:20:04 | 0:20:12 | |
Tees Cottage pumping station is on the River Tees at Darlington. | 0:20:12 | 0:20:17 | |
My little balancing act demonstrates the smoothness of the precision engineering. | 0:20:19 | 0:20:26 | |
-Superglue. A bit of kidology. -I don't think it's stuck on! -No? | 0:20:29 | 0:20:34 | |
-There you go! -The thing is, getting it back on! Here goes... | 0:20:34 | 0:20:40 | |
-Hurray! -First time! How about that, then? | 0:20:42 | 0:20:46 | |
At Tees Cottage you can see the beginning of the demise of the beam engine | 0:20:46 | 0:20:52 | |
because just next door there's a gas pumping engine that worked alongside the beam engine | 0:20:52 | 0:20:59 | |
from 1914, before replacing it completely in 1926. | 0:20:59 | 0:21:04 | |
-Quite a rare engine. -I must say I've never seen a gas engine as big as this! | 0:21:04 | 0:21:11 | |
-One of the bigger ones in the country. -Yeah... | 0:21:11 | 0:21:16 | |
-We got this running 10-12 years ago. -Yeah? -Quite a risky business. | 0:21:16 | 0:21:21 | |
-We thought we'd put everyone's gas heating out! -All cooking their turkeys? -And no gas in the cookers! | 0:21:21 | 0:21:29 | |
In spite of new types of engines like this one being introduced, the steam engine didn't just disappear. | 0:21:34 | 0:21:41 | |
Smaller engines were used for the manufacture of all sorts of domestic products. | 0:21:41 | 0:21:47 | |
I found an interesting example on a restoration job near Penrith. | 0:21:47 | 0:21:53 | |
This is Wetheriggs Country Pottery in Cumbria | 0:21:57 | 0:22:02 | |
and this wonderful thing is a blunger! | 0:22:02 | 0:22:06 | |
I thought they were kidding me when they mentioned, like, "blunger"! | 0:22:06 | 0:22:11 | |
Believe it or not, this is the last steam-driven one in existence. | 0:22:11 | 0:22:16 | |
And when I came here five years ago it was ready to fall into the pit. | 0:22:16 | 0:22:21 | |
Its function is... Over the road there were a big clay pit, in the olden days. | 0:22:21 | 0:22:30 | |
The clay contained a lot of pebbles, and they put it in this pit, added water, | 0:22:30 | 0:22:37 | |
and the machinery stirred it up | 0:22:37 | 0:22:40 | |
till it were like milk chocolate and the stones fell to the bottom. | 0:22:40 | 0:22:45 | |
then they pumped the liquid clay off the top into a lagoon over the back here. | 0:22:45 | 0:22:52 | |
And when the clay settled on the bottom and the water became fairly clear, | 0:22:52 | 0:22:58 | |
they pumped the water up the top, back up the hill again. | 0:22:58 | 0:23:03 | |
When the clay had set, they dug it out in big blocks, and brought it up here to make pots out of it. | 0:23:03 | 0:23:10 | |
Really, it's like a big cake mixer, | 0:23:10 | 0:23:13 | |
all driven by a little steam engine in this engine house. | 0:23:13 | 0:23:17 | |
-HISSING -This is Josephine, the engine that drives the blunger outside. | 0:23:17 | 0:23:23 | |
And it took me and my assistants | 0:23:23 | 0:23:26 | |
about six months, seven months, to restore it. We took it to bits... | 0:23:26 | 0:23:31 | |
carted it back to Bolton, restored it all and brought it back here, | 0:23:31 | 0:23:36 | |
and here it is, driving all the machinery in the pottery! | 0:23:36 | 0:23:41 | |
That noise next door is the boiler. They've put a bit too much coal on and it's blowing off! | 0:23:41 | 0:23:49 | |
As far as we know, this is the only example of a steam-driven potter's wheel in existence. | 0:23:52 | 0:23:59 | |
In some industries, steam power never replaced water power. | 0:24:00 | 0:24:05 | |
Wheal Martyn China Clay Heritage Centre is in St Austell. | 0:24:05 | 0:24:10 | |
Here at Wheal Martyn, this really is one of the best examples | 0:24:10 | 0:24:15 | |
of a water wheel moving things around on an industrial site. | 0:24:15 | 0:24:20 | |
-I mean, how long has it been here, Terry, doing this? -This 18-foot wheel has been here since 1902, | 0:24:20 | 0:24:27 | |
and it was pumping slurry around the site right up until 1962. | 0:24:27 | 0:24:33 | |
It picked up slurry from the pit, and using those pumps down there, | 0:24:33 | 0:24:39 | |
pumped slurry to where it was required. | 0:24:39 | 0:24:42 | |
This is it! Technology from a long time ago. | 0:24:42 | 0:24:47 | |
-This is the core of the business here. -Yeah. -The tail-end of that waterwheel power supply. | 0:24:47 | 0:24:54 | |
It gives a bit of a shudder when it goes into reverse! | 0:24:54 | 0:24:59 | |
The thing to remember is that none of these sources of power | 0:24:59 | 0:25:04 | |
have ever really gone away. | 0:25:04 | 0:25:07 | |
Take water. We still use it to generate electricity. | 0:25:07 | 0:25:11 | |
Here at Ffestiniog hydroelectric power station, | 0:25:11 | 0:25:15 | |
this lake is 1,000 foot deep, a 14-foot diameter shaft under that building there. | 0:25:15 | 0:25:22 | |
When they pull the plug out, down goes the water and works a water turbine | 0:25:22 | 0:25:29 | |
1,000 feet down the mountain. | 0:25:29 | 0:25:32 | |
This thing down here is the main sort of bowel | 0:25:35 | 0:25:40 | |
that holds back the pressure 1,000 feet up the mountain. | 0:25:40 | 0:25:45 | |
A nifty piece of engineering. | 0:25:45 | 0:25:47 | |
I don't know what they do when they want to change a washer! | 0:25:47 | 0:25:52 | |
When it opens, the water comes down, through to the water turbine, and generates electricity. | 0:25:52 | 0:26:00 | |
All very clean and environmentally friendly. | 0:26:08 | 0:26:11 | |
We've come full circle - these wonderful windmills, looking like aeroplane propellers. | 0:26:11 | 0:26:18 | |
Somehow or other, I don't think they'll ever beat the steam turbine. | 0:26:18 | 0:26:23 | |
This lot here - it all works. You could drill a 2.5-inch hole for an iron bar. | 0:26:30 | 0:26:37 | |
You could forge a big lump of iron two inches square, or saw a piece of stone in half, a foot thick. | 0:26:37 | 0:26:44 | |
So I don't think I've done so bad with all the junk that would have gone to scrap yards, but for me. | 0:26:44 | 0:26:52 | |
This weird and wonderful machine is for making iron bands to go around factory chimneys. | 0:26:55 | 0:27:02 | |
All the bands at Barnoldswick were made with this machine. | 0:27:02 | 0:27:07 | |
In fact, really, everything here works with the power of steam. | 0:27:07 | 0:27:13 | |
All the work on my engines, both at Caernarfon and Wetheriggs Pottery, | 0:27:13 | 0:27:18 | |
has all been done here with this steam-driven machinery. | 0:27:18 | 0:27:23 | |
Even renovating my tractor. It's all been done by steam power. | 0:27:23 | 0:27:27 |
