The Centre for Alternative Technology presents, Earning a Living in a Changing Climate: A Vietnamese Perspective on Climate Change, combined with good food and conversation in a free talk this Thursday at 7.30 in CAT’s Quarry Cafe in Machynlleth.
The guest speaker Nguyen Quang Minh, is Livelihoods Programme Coordinator for Oxfam Great Britain and works with some of the poorest people in Vietnam to help them earn a living. Minh will talk about the impacts of climate change in Vietnam and some of the practical solutions for communities to adjust to these pressures.
“Though at opposite ends of the world there is actually a lot in common between what Minh does in Vietnam and what the Centre for Alternative Technology does. Machynlleth has an established Oxfam group and so bringing Minh to Mach is a great chance for supporters to hear first hand about the work their support enables.” Representative from Oxfam Cymru.
Minh will cover issues from food, income, climate change and the gender challenges that Vietnamese communities face through his everyday work and how he is tackling these issues through initiatives such as community based forest management as well as policy and grassroots work to develop long-term livelihoods to help overcome poverty.
Over the next two weeks Minh will be visiting Wales, as part of an ongoing project by Oxfam Cymru to bring the experiences of people working in the developing world to communities in Wales.
Food will be served in the Quarry Cafe from 6.30, in time for the talk at 7.30 followed by a question and answer session. Join us for a stimulating debate over dinner, at the Quarry Café and find out how your support for Oxfam Cymru could help to change the lives of others across the world.
This summer children visiting CAT had the chance to explore climate change and renewable energy in a series of play activities and carnivals. The activities allowed children to explore how our reliance on fossil fuels affects the climate and what the alternatives are.
Here are some photos from last weeks ‘Power Down’ carnival in which children made their own transport out of recycled materials, dressed up as people from their vision of a zero carbon future, paraded around site and finished on the lawn with smoothies from the bike powered smoothie maker and music powered by our bike generator.
This week, Jase Kuriakose an engineer at CAT turned on the UK’s first totally renewable micro grid.The systems works by combining all the wind, solar, bio mass and hydro energy we produce at CAT and storing it in a battery bank. When it needs more energy it simply connects to the grid through an intelligent electronic control device to take more, when we are producing too much it gives the energy to the national grid.
Currently we waste around 65% of energy from power stations by transporting it to our homes, not only that but the electricity sector in the EU is responsible for over 1,2 billion tonnes of carbon dioxide every year.Something that Jase says is unsustainable.
“There is a vital need and enormous opportunity to move towards a more sustainable decentralised system, which protects the climate and provide future generations with secure energy.”
On Friday Phil Horton the project manager of our biggest building project took some of the CAT staff on a tour of the construction site. The Wales Institute for Sustainable Education is the biggest project we’ve ever undertaken. Phil showed us many of the sustainability features of the building including the hemp lime render and rammed earth walls in the lecture theatre.
For schools, colleges and universities in Wales, the centre at Machynlleth in Powys, half an hour’s drive from Aberystwyth, is a resource that runs a free information service, visits for schools and residential courses.
The centre has teamed up with the University of East London which validates specialist diplomas and Masters degrees delivered by academic staff at the centre. It offers an architecture MSc and a Masters in renewable energy and the built environment. Student Owen Morgan, 26, says enrolling on the MSc course helped him land a job with Bright Light Solar, a mid-Wales renewable energy company which provides solar powered vaccine fridges, water pumps and heating systems to rural areas worldwide.
“Everyone is there because they are passionate about sustainability. We inspire each other to push the frontiers of what can be achieved,”
By 2007, there were 2GW of turbines installed. The British Wind Energy Association (BWEA) says 9GW of offshore wind will be in place by 2015, overtaking installed nuclear power. This month, Centrica and RWE npower came close to approving two offshore wind farms costing an estimated £3bn.
Three short films have done the rounds and got us talking in the staff room this week. All three have also generated a fair amount of chatter on the Facebook page.
The first two films are very different but powerful demonstrations of the effect climate change will have on less developed countries. The third film is a lecturer by American academic Jared Diamond in which he outlines why some of the greatest societies in human history have collapsed and explores whether we are headed in the same direction.
The videos are embedded below. If you’d like to suggest something for the next video round up please post a comment.
The charcoal industry has had an interesting history, once being the staple commerce of woodlands in the British Isles, it provided work for many and was a quintessential part of our landscape. Soon after the discovery of coal as a fuel source in the early 1700s charcoal became an unprofitable venture, and the woodsmen who made it became a part of history, lost to the beginnings of the industrial revolution.
So who would have thought, that 250 years after the first use of fossil fuels we would be turning back to charcoal as a means of undoing the damage of those emissions. Poetic it may seem, but to those who are studying the capacity for Biochar to sequester Co2 from the atmosphere, this is an all too real opportunity. And it doesnt stop at mopping up emissions; Biochar has the potential to improve degraded agricultural land and reduce fertiliser dependency while creating rural jobs, providing a use for organic waste and becoming an integrated part of our biomass energy systems.

The small nation of Wales will be presenting some huge ideas at this year’s Smithsonian Folklife Festival in Washington, DC, later this month. Experts will discuss the future, including the buildings we could live in, the food we might eat and the way we could use energy in a world without fossil fuels.
The Convergence on Zero event (from 25-26 June) will present leading thinkers from climate science, energy, politics and technology. The event is free, and open to anyone interested in the big questions about the 21st century – climate change, oil depletion and the economic crisis.
As the sun’s finally shining and our seedlings are ready for planting out, now’s the time for turning in the green manures on site. In these pictures you can see me turning in the field beans in our green manure display, where we demonstrate a few different kinds and what they’re used for.
Green manures are a key part of organic gardening, and they serve a number of different purposes. They improve soil structure, prevent soil erosion, can inhibit weed growth and most importantly, increase the soil’s fertility. The main idea is that you grow a certain green manure crop on your land, and when it’s still young (about 6 weeks is perfect), you ‘turn’ it in, or dig it in. The plant then slowly releases its nutrients as it decays and increases the amount of organic matter in the soil. Green manure crops are hardy and can be grown over winter and spring, so you don’t need to leave the ground bare.
Field beans, like all of the bean family, is a nitrogen-fixing plant. It has little nodules on its roots where nitrogen-fixing bacteria live in a fascinating mutual relationship- the bacteria transform nutrients from the air into a form usable for the plant, and the plant feeds the bacteria with sugars from its roots.
There loads of great green manure crops that can be grown at different times of year and well in different climates, or even as a ground cover underneath other crops to increase fertility year round so do a bit of research and plan some into your sowing calendar
With a mix of excitement and trepidation, I watched the 3½ tonne hot water storage tank get craned into place next to our new woodchip power station. Its job is to act as the thermal store – a big hot water storage tank – for the whole of our district heating scheme. This was the final piece of the puzzle the CAT engineering team had been waiting for.
Its importance is that we can now begin the final stage of connecting the new Combined Heat and Power (CHP) system up to the site district heating network and the new WISE building, and get all of the testing done in time for the winter heating season. This will draw to a close the design and installation stages of a project I have been working on for almost 3 years.
However, it does not stop there, as the installation is only one part of our site energy strategy. In September, I will start my doctorate research into biomass CHP, and its potential for community scale systems in the UK. Hopefully this will give others the opportunity to learn from the results of our experiments in this fledgling field of energy generation.
I tried to remember the importance of this, as the tank was lowered into place and set into its permanent home, ready for its connection, but a wry smile crept across my face every time I saw the big yellow crane and I remembered that engineers never really grow up!
