Harnessing waterpower

With heavy storms and 6 cms of rain predicted, you’re most likely this weekend to have been thinking of flooded towns, marooned houses and spoilt travel plans. Essential for life, water can also of course destroy. Torrential rivers, tsunamis, melting icebergs and rising sea levels pose huge problems and threaten lives.

But these last two weeks I’ve been intrigued by two apparently unconnected examples of how the power of water has been harnessed to improve living conditions, grow produce or promote new industries.

The Romans were famous for their aqueducts, which were illustrated in Vitruvius’ treatise De Architectura, the only surviving book on Greco-Roman building techniques. Written between 30 – 20 BC, it was rediscovered in 1414 by the Florentine, Poggio Bracciolini; and was discussed recently in Melvyn Bragg’s In our time Radio programme (15 March 2012).

On a walking holiday in southern Turkey this month, we climbed on the hills above Patara, an important Lycian seaport c 120 BC in Roman times and had the opportunity to explore a huge aqueduct there, made up of hundreds of massive precisely shaped square stone blocks. (See top photo)

Their ‘cuff and sleeve’ design for each stone, which involved the male end of the first stone entering snugly into the female cuff end of the second stone and so on down the chain, enabled the Romans to transport via a syphon system over undulating land, huge quantities of water from the hills down to the port. (See second photo)

The surprise came this last week while I was doing some clearing at the top of the garden at The Larches.

Just over the wire fence behind the seat on the Buena Vista crag, I noticed a rounded moss covered shape on the ground.

Investigating further with a spade and brush, I discovered within a few minutes two lengths of cast iron pipe. Each one was 12½ feet by 12 inches diameter, with virtually the same cuff and sleeve design we had seen in Turkey.

I had known there had been been a pipe line from the old dam at the top of Comb Beck from sections I had seen further down the valley. This had been used for the Thornthwaite Lead Company’s mine at the bottom of the road and had been built in 1908.

Later in the 1930s when the mine was closed, the water pipe was used to power a small hydro-electric scheme for people living in Seldom Seen.

It’s fascinating to think that technologies developed by the Romans almost two millennia earlier were being used a century ago to develop new industries here in Cumbria on our doorstep.

Laptops for Nepali schools

Seven years ago we went trekking with our son Barney and daughter Chloe through the Tiger Leaping Gorge in Yunaan, China. We marvelled at how as travellers we were able to communicate with the outside world.

The photo below shows Barney with his Blackberry high above the mighty Yangtze River, conferencing ‘on the hoof’ with colleagues in Beijing. The photo opposite of all our mobile communication devices was taken at the Halfway Cafe in the gorge and features in my book ‘Digital Nations in the Making‘, published in 2006, on the uses of technology with adult learners.


.
Yesterday provided an exciting follow up to all this, as we met up with Chloe and her partner Henry at the Wellcome Collection on Euston Road. She had stopped over in London on her way from Seattle to Katmandhu in Nepal, where she plans to set up a technology project with an initial three primary schools.

Fortunately Barney has helped here by arranging for Orbitz Worldwide (NYSE:OWW), the online travel company in Chicago where he works, to donate ten reconditioned Thinkpad laptops. These are ideal for piloting this learning through technology scheme in the high mountains of Helambu.

We ourselves had already transported five of these laptops across from the US two weeks ago and Chloe brought a further five with her.

The Nepali partners in the project will include two of Chloe’s students whom she taught in 1993 at the village school in Shermathang (3,000 m). They now work for local NGOs there and are keen to explore with the schools and children the environmental and sustainability issues which affect upland communities in the Himalayas. The laptops provided by Orbitz Worldwide will be of particular help for the teachers.

The photo above shows Chloe yesterday with her iPad, displaying a picture she had taken 19 years ago of a young girl at the school, sowing seeds brought from the UK. It will be useful as an information resource as they visit the different schools.

There’s plenty to organise for the project like ensuring the children carry out a census in each area and checking that each of the schools has reliable electricity. Internet connectivity is another hurdle to overcome – a problem familiar for adult education bodies in the UK even now.

The challenges facing the project are considerable which is why the New York based Explorers Club – where Chloe is one of the youngest members – has agreed to loan one of its coveted flags for the expedition.

“Does everyone get one”, I asked her. “Oh no”, she replied casually, “you have to put up a good case. Best known perhaps is the flag, which Neil Armstrong took to the moon. He’s one of our members you know.”

The photo opposite shows Chloe and Henry displaying the flag at the Wellcome Collection. If you are interested in finding out more, making a donation for the project or helping in some other way, drop me a note at ian@lakelandbelvedere.com

Our thanks to the Wellcome Collection and staff for their help and provision of space for us to meet and plan arrangements for the project.

Amazon’s reach and waste

We are always glad to have suggestions for improvements at the Larches and rapidly decided we needed to get two new knives – a bread knife and cook’s knife – when our New Year guests commented about the existing ones.

Antique? Well not quite but old, pre stainless steel certainly and quick to rust, if not dried after use.

But the decision made us also think about how best to store all the knives for easy retrieval. So this last Sunday after a lunch time discussion of alternatives, we decided on a magnetic knife holder.

They work like magic. I’d always fancied one but we’d never had the right space for it.

So log on to Amazon – yes we could have one and at 3.32 pm an email confirmed the 40 cms long rack had been dispatched with free next day delivery.

As promised, the van drew up a little after 2.00 pm on Monday and the parcel was handed over and signed off.

Amazon had got the rack selected, packed and delivered to a country area in under 24 hours from a Sunday start. Impressive.

No complaints there. This is online shopping at its best and saved me a lot of time.

But the box (opposite) was a different matter!

Slitting it open I wondered first if there was anything there. Loads of brown scrumpled up paper tumbled out, but no sign of the rack.

Finally I found it at the bottom, well packed in its own box. It measured 2 x 5 x 47 cms, so it didn’t take long to work out the Amazon delivery box (11 x 35 x 55 cms) would have held easily 34 of the racks – if I had wanted that many!

And that scrumpled up paper? On inspection it turned into a long seamless sausage-like creation, which flattened out into one continuous length of paper over five metres long by 38 cms wide.

For just one knife rack they had needed, because of the over large box, a length of packing paper that stretched from the eaves of the cottage to the flower bed – as you can see in the photo at the top of the page.

I’m a fan of online shopping because it can save on ‘travel to search’ time and costs. But the calculations from this example about use of resources are pretty scary. Just a hundred similar Amazon deliveries would use up 500 metres of the packing paper, which would either be thrown away or recycled at best. How many trees do you need for this and for the over large packaging?

The knives look great now and I had them installed on the new rack by 3.30 pm on Monday. That’s good going – a 24 hour turn round for job completion is fast. But isn’t it time Amazon looked at its wasteful packaging policies? No gold stars here for good environmental practice.

New roof for The Larches

P1020106 Over the last five weeks The Larches has been surrounded by a girdle of scaffolding.   We’ve known we really needed to have the house re-roofed for over a year. Trying to hold many of the lower slates in place proved impractical. The result was leaking from the gutters especially at the back and the danger of slates falling in high winds.

A new year’s resolution got us finally to move! And when the roof was stripped the rotten soffits and some defective joists proved how right we were. 

It’s been interesting to pull back the curtain of time to get a glimpse of how the house was built over 125 years ago and to see how roofing techniques while modified, still retain much of the traditional practice. Perhaps the biggest difference comes with the weather and wind proofing. 

The old roof was sealed throughout by parging. This is a method of coating the batons and the undersides of the tiles with parget – a mortar of lime and horsehair. Nowadays this has been replaced with a much simpler and quicker method, where a breathable membrane sheet is secured under the batons and the slates are nailed to the batons.       

Fortunately the original Borrowdale slates (about 10 mm thick) were strong and of good quality, as Frank the roofer had predicted, and the majority could be resized and reused without breakage. In this way the vernacular style of a graduated roof can be retained with the largest slates being used at the bottom and the smallest (and shortest) ones covering the top rows of the roof. Replacement ones are primarily for the bottom rows.

Since modern slates are almost invariably thinner (to reduce costs), second hand Borrowdale slates, suitable for environmentally sensitive areas and similar to the ones we have, are hard to come by and now sell at a premium price of £3,000 a ton.

The photos below show the back roof ready for the slates, the roofers working up the rows from the bottom, the look of the completed roof after a chimney has been removed and finally the filled lorry after the scaffolders have spent a morning dangling acrobatically from poles as they dismantled the scaffold and boards. It’s been fascinating to walk all round the house at roof level to see the work, but now we’re glad to be back to normal.

Recycling the showman’s way

P1010076 We were down south last week and had the good fortune to spend a while with members of the Harris family, a showman community based at The Orchard just outside the village of Ashington in West Sussex.

Living and working in the same spot since 1902, they trace their antecedents back to John Harris, a Tyneside basket weaver who settled in the area in the 1850s, working initially as a forester and timber merchant. By the 1860s he had started the fairground business with his sons, buying one of their early steam roundabouts from a Tewksbury manufacturer in 1890.

P1010068 Now run by five brothers and two sisters, the business involves transporting equipment and running their fairground in villages and towns all over this area of rolling downs, meadows and woodland. They also hire out individual items for weddings and special events. Volunteers, who love the laughter and excitement of the fairground scene join in regularly to help with the swing boats, roundabouts, gallopers and side shows.

Hard to classify, fun to be with and dining mostly together, the family extending across generations is like some utopian example of the Arts and Crafts movement – a time capsule that has refused to die. Living close to nature, they are above all immensely practical, turning their hands to any job.

P1010083 They’re experts too at recycling, throwing little away and collecting useful items over the years. “Just put it under the hedge – you never know when it will come in handy”, says Rob, one of the brothers when I asked what they did with old gear. (See photo of field opposite they have recently acquired.) It reminded me of the MOMA Waste not installation we saw in New York last year.

The Scammel trucks for towing the equipment are ex WW2 stock, so you can’t just pick up the phone for a new spare part. A replacement for an axle on one was found from a hedged machine. Another truck was re-fitted with an old Rolls Royce engine (See photo at the top).

P1010065 With a little imagination there’s not much they can’t find a useful home for. An old shop display model now keeps watch in a large greenhouse where the tent canvases are dried after a downpour. An old galloper (below) has been put out to grass – for the time being – on an empty landing. Objets trouvés like the old cow advert (below) reflect a simpler rural economy.

Can this real life example of Cameron’s Big Society idea – with up to 70 people actively involved in a small community based business – survive in an increasingly competitive and slick leisure field? The work is hard and seasonal and depends on hours of unpaid labour. Time only with tell. But if you have a chance, try out the Gallopers or the Paratroopers at their next Fun Fair. You won’t be disappointed with the experience or the friendliness of the Harris fairground.
