Photos – Knit your own carbon dioxide workshop

Diana helped with a workshop mid-exhibition. We had a great time learning a few new knitting stitches and techniques, and though we didn’t finish a whole knitted carbon dioxide molecule, we did manage to make one out of pompoms!

The conversation flowed over a whole range of ideas and issues. Chloe Uden from RegenSW told us about the SWIMBY musical about the Transition movement. It’s going to feature someone knitting in a corner throughout!

Composer Emma Welton brought some hi-tech equipment to record the sound of knitting. Her interest is also in energy generation, so she has been recording wind turbines, hydro-electricity, and large-scale power stations. Looking forward to hearing what she creates out of it all.

Photos – “Up in the Air”

Photos of the exhibition in the Glorious Art House, Exeter, from 11-24 July 2015.

The gallery on the second floor became the Earth’s atmosphere, as particles hung in space around an inflatable globe. But the particles were also hung according to three pieces of data. So the gallery was also effectively a 3D graph. It even had axis labels, because if one is going to be a data geek, one may as well go the whole hog!

The posters around the room supplied the salient data about each particle, and the particle structures and the data also provided the material for some games – Turn Up Trumps and Fair Weather Friends – based on a couple of family favourites. There was a wordsearch too, all available to play nestled among the cushions in the games alcove.

And finally, there were leaflets about the exhibition and knitting patterns available to take away. You can find out more about the issue of climate change and what you can do, and download the patterns and games, on the “Up in the Air” exhibition page.

The Glorious Art House on Exeter Fore Street. Truly glorious!

"Up in the Air" showed over 11-24 July 2015 in the gallery on the second floor of the Glorious.

The gallery was transformed into Earth's atmosphere, containing eight greenhouse gases that are contributing to climate change.

Axis labels at [0,0,0] on the gallery as 3D graph. Well if one is going to be a datageek, one may as well go the whole hog!

The wall posters provided the particle names and structures, and the salient data which dictated where the particles were hung in the gallery.

There was lots of take-home stuff. Knitting patterns appeared after the knit your own carbon dioxide workshop, which happened mid-exhibition.


There’s something in the wind…

Amidst all the excitement of “Particulart: Up in the Air”, let’s not forget our origins, critiquing the Incinerator. In the 16th July edition of Express & Echo, there was a short update on Recycling in Exeter.

2015-07-16 E&E p44

Diana and I couldn’t let this pass. I was particularly struck by the nonsensical “contributing 3MWh per hour of operation to the National Grid”… which just means the Incinerator’s generation capacity is 3MWe, and tells us nothing about the number of hours of operation and how much electricity it has actually generated. Diana is currently trying to get hold of some data for generation and operating costs. In the meantime, I have compared it with the capacity and cost of wind generation.

OK, so according to its communications, the Incinerator was expected to cost £45m, and has a capacity of 3MWe. That’s £15m per MWe. The cost of generating each kWh is to be determined.

Let’s take offshore wind, which the UK is quite good at. Each turbine in the London Array, commissioned in 2012, has a capacity of 3.6MWe. At the moment, the average cost of capacity is 2.5-3.0 million Euro/MW, or up to £2m per MWe; and the average cost of generation is 161 euros ($208) per MegaWattHour, or 11p/kWh.

So the Incinerator has a smaller capacity than one wind turbine, and costed 7.5 times as much per MW!!

Here’s the Incinerator equation for garbage in, garbage out:

(carbon content of waste + rest of waste) + oxygen + other reactive gases
   → carbon dioxide + other flue gases + flyash

Some estimate the carbon content to be 27% of the total waste, which means that incineration of 1 tonne of waste would produce approximately 1 tonne of carbon dioxide. Others put the carbon content at nearly 50%, which means 1 tonne of waste in, nearly 2 tonnes of carbon dioxide out.

The Incinerator is designed to accept up to 60,000 tonnes per year of waste. That means 60,000 to 120,000 tonnes of carbon dioxide emissions every year. Exeter has a population of about 120,000. Ignoring the carbon footprint of building the Incinerator and offshore wind, and of other operations such as waste delivery, flyash removal and maintenance…

The Incinerator adds 0.5 to 1 tonnes of carbon dioxide to every person’s annual carbon budget. Offshore wind is zero carbon.

Furthermore, that is 60,000 tonnes of waste that has not been reduced, reused or recycled. It is not very surprising that recycling rates in Exeter have gone down, since the Incinerator needs feeding.

Now let’s turn to Diana’s main concern…

Food waste makes up about 36% of the waste input to the Incinerator, and it could instead be be composted or processed more efficiently in a anaerobic digester to produce biogas. The point about the garden waste scheme is not relevant regarding food waste, as the scheme really does only collect garden waste.

Diana thinks the point about the cost of food waste collection is a cover up for the fact that Exeter City Council’s negotiations with Teignbridge and East Devon District Councils on food waste collection have recently collapsed.

Here’s another article from Monday’s Express & Echo, which makes the arguments over the cost of collection academic.

2015-07-20 E&E p7

So if food waste is rightly diverted away from the Incinerator, where will all the waste to feed it be sourced?


Photos – “Up in the Air” set-up

Clare managed to get in to the Glorious a couple of days early, so has already set up. Difficult to take photos of the whole room with only a smartphone – need a proper camera with a fish-eye lens! But hopefully these give a flavour of the transformation of the gallery into the Earth’s atmosphere and a 3-dimensional graph via the medium of knitting and chemistry!

Knitting exhibition shows climate change to be ‘Up in the Air’

Embargoed until Tuesday 7th July 2015

An innovative art installation goes on show this week to bring alive the greenhouse gases that are causing climate change [1]. Local artist Clare Bryden has been knitting larger than life versions of the particles and making card games. The exhibition [2], which will be on display from 11-24 July at the Glorious Art House in Fore Street Exeter, is designed to be a playful way of sparking people’s interest in the science and issue of climate change.

Clare said: “This year is vital, as governments are meeting in Paris in December, and hopefully they will come to a ground-breaking agreement on the climate [3].

“Exeter is home to two world-class climate research centres at the Met Office and the University. They are advising the government on how human activity is changing the climate, and what reductions in greenhouse gas emissions we need to make to avoid dangerous climate change.

“The government also needs to hear the concerns of the ordinary person in the street. But because the climate is changing over such a long time-scale and the potential impacts are so huge, it’s difficult to talk or even think about it [4].

“Climate change is happening up in the air, and the outcome of the negotiations in Paris is up in the air too. Knitting and making card games are my ways of bringing it all back down to earth.

“I wanted to appeal to the different ways that different people take in information, both through words and numbers, and through the senses of sight and touch.

“This exhibition is a creative way of getting a serious message across. I have knitted carbon dioxide and methane amongst others and I urge people to come along and have a play! We will even be holding a workshop [2] where you can knit your own carbon dioxide.”

‘Up in the Air’ is supported by a Small Arts Grant from Exeter City Council and sponsorship from the Diocese of Exeter.

Co-founder Clare is ‘Up in the Air’

On 3rd July, Clare jumped out of an aeroplane in aid of Hospiscare, Exeter. Fellow co-founder Diana made the link between the skydive and Clare’s forthcoming Particulart exhibition ‘Up in the Air’.

Clare writes: “It was touch and go, as my doctor’s form didn’t have the proper stamp, which meant panicked form-refilling and scanning and emailing and stamping and signing and scanning and emailing and printing and stapling. But anticipation gradually took over from stress, and then there was the spiral up to the jump height, the shuffling forward on the benches towards the gaping door, and the moment of sheer panic as I knelt on the edge and was tipped forward into oblivion… and then we levelled out and I could enjoy the sense of freefall for an all-too-short minute.”

If you would like to, it is still possible to sponsor Clare at

“Particulart: Up in the Air” opens on 11 July!

GloriousBuy a coffee and cake from the Glorious café on the ground floor, and wander up to the second floor gallery for 3D knitted molecules floating in the Earth’s atmosphere! Interactive card games! Cushions! Data about greenhouse gases! Something for everyone, in fact, including your inner or not-so-inner geek.

The Glorious Art House is at 120 Fore St, Exeter EX4 3JQ. The opening hours are currently Mon-Sat 8am-6pm and Sun 10am-4pm. For the latest information, please see their Facebook page.

Article in Third Way magazine

Clare’s article about Particulart and the wider craftivism movement has now been published in May’s issue of Third Way magazine with the title “Knitting and other revolutionary acts”:

As competing political voices reach election crescendo, could it be that artistic, home-spun forms of activism are more positive and quietly persuasive? Clare Bryden hails the rise of ‘Craftivism’ and explains how knitting can change the world.

It’s available on Third Way website, unfortunately behind a paywall. Update: it’s now also available on this site.

Pint of Science

On Monday, I took Particulart into the unfamiliar territory – The Ship Inn in the middle of Exeter – as part of the annual worldwide Pint of Science festival.

The talk was one of three on the theme of Sustainable Science, to a goodly crowd squeezed into the Ship’s upstairs room. The pub claims to have been Sir Francis Drake’s favourite watering hole, but I’m not sure what Drake would have made of our talks on solar energy, knitting and cellulose. Maybe he’d have related them to navigation, and the Golden Hind’s rigging and timbers.

Particulart also provided one of the interval activities, as the audience were challenged to assemble molecules from piles of coloured disks nobly cut out by a volunteer. That was followed by a nigh-on impossible quiz about the three subjects.

A key feature of the evening was of course the trip to the bar beforehand, during the interval, and afterwards, which enabled some good discussions. This is one of the main points of Pint of Science, of course.

The Pint of Science festival aims to deliver interesting, fun, relevant talks on the latest science research in an accessible format to the public – all in the pub! We want to provide a platform which allows people to discuss research with the people who carry it out. The main festival takes place annually over three days in the month of May simultaneously in pubs across the world.

Next year’s festival will be on 23-25 May 2016.
