Winter in Scotland

Scotland was covered in snow this winter for weeks - weeks! I can never remember this happening.













Anyway, it was nothing short of amazing. But to keep this short lest I never actually post these pictures up, and never get time to catch up with everything else that's going on, I'm going to get on and talk about our igloo.


It all started with some mediocre sledging attemtps, which then turned into massive snowball making sessions. We rolled these lumps together and made the first wall. Never having done anything like this before we just gave it a bash, making each layer lean progressively inwards...


Pretty soon we had a couple of walls heading towards each other. Shawn's pizza oven design helped to understand how a vaulted structure holds together.

Nikita (principle architect and builder) and myself before the roof closed in further.

By this time we'd put hours into this thing, not knowing if it was going to thaw anytime (we needn't have worried. It stayed sub zero and covered in snow on and on).

But as the temperature dropped to -5, then -10 the snow became unworkable. It needs a bit of stickiness to it to work as a binder...


Nice spot for a winter home






Basic entry way done, we had our first guest - John, fresh from living in the Highlands in caves and bothies, was happy to give it a test fire, with a couple of sleeping bags and decent underlays.


John insists he slept like a baby, despite the gaping entry way and meagre tartan door.

So next warmer day Nikita and another crew of enlisted volunteers (shown right)














built a classic crawl through entry way... we then imported some raided straw from the local farm, carpet felt, a donated carpet (thanks Vicky!) built a few candle shelves and we were set up for the night. Cosy one we had too.











after which it became our external party house / meeting point. Wish we'd slept there EVERY night....














Team Traquair clearly taking over here:)


Parting shot, moring of departure.

How to make soil / Como fazer o solo?

How exactly do you get food to grow in depleted or poor quality soils? I've tried with little success in Scotland, Kenya, Liberia and now Portugal. What's the trick?

Now settled in one place for more than a few months, a village where people grow vast quantities of amazing-looking things in their gardens, I have seen a few seasons pass and have listened to their stories about what they do to make it all work. Also, we have Paulo on site much of the time: our very own walking permaculture encyclopedia, who's always keen to see the theories into practice.

Although permaculture design covers far more than the growing of vegies I can't help notice the huge differences between the two systems (local's gardens and permaculture growing). Here are a couple of major ones:

Normal gardeners dig their soil over each year, usually use this opportunity to add in some manure of other fertiliser. Heaps of work, happily avoided in permaculture's no-dig method: just cover the soil with loads of mulch (described below), avoid walking or compressing the soil and ecourage loads of soil life to develop: bacteria, fungi/mycellia, insects, worms, and millions of other mini-actors we barely understand but are responsible for making great soil if they have the right conditions. Digging the soil wrecks their world (and is way too much work too).

Weeding: another reason I always avoided gardening - loads of boring work. Instead, put down sheet mulch (shown below) and the weeds are denied light and can't live. Replace them with plants you want. Easy. OK, supposed to be. I'm sure there is more to it, but it has worked for us so far.

Couple of test sites here.

This is a South facing terrace that bakes in summer. Trying to build up soil there to plant berry bushes and small trees and kiwis to shade the whole area.
Neighbour's dog, Pinnochio (our dog's best friend by far) tramping all over it already the swine. We had just pruned a large bit of the mimosa (acacia) tree planted last year, for nitrogen mulch...



This is the next terrace up, the "chicken terrace". Here we want to build up an edge, to keep water on the terrace a bit longer, but also build up soil quality to grow things in. So we started with cardboard, then some nice looking soil with old manure on top, then forest leafy stuff, then newspaper, well soaked. then straw. We found 35 tiny strawberry plants in the shop and punched holes through the damp mulch bed and popped them in. Oh, we installed some micro irrigation pipe below the cardboard too, to avoid the drudgery of summer manual watering...
















Teuru, admiring our handiwork. Next stop: strawberry heaven.



And here is the first garden patch we started this Spring (09). We chunked it full of tomatoes and squash and green peppers. As they started withering into winter, we planted in some lettuces, cauliflower, brocoli, onions and any other winter thing we could find. Where we found weeds we covered them with more cardboard and straw. It seems to go OK, and the soil is imroving a lot, but slugs have chowed through a good share of those new leaves. So next up is how to deal with slugs. Any ideas anyone?

Copenhagen climate conf: best videos so far

They say it's the most important meeting in history, so much at stake, tens of thousands of people there, millions like me here and can't go. How do we keep up with what's going on?? BBC and all the usual media sources provide slim pickings, not much radio or video worth mentioning, or just interview the senior politicians or advisors (eg Nicholas Stern).

However, the Stupid Team (who made Age of Stupid) have the best show ever, covering each day, intereviewing heaps of key people and dealing with the rising tide of climate change sceptics. Why is it that more and more people are starting to believe the rubbish dished out by the climate deniers camp? Anyway, these videos say it all.

1. The Stupid Show



2. Desmond Tutu's speech to the crowd (that guy rocks)



3. President Nasheed of the Maldives (what a President to have?!)



4. Ambassador Lumbumba chair of the G77 group of nations (this one a bit longer and more serious, but his points are classic)

Thesis on watermills to generators

I just realised that I can share my thesis with anyone if they are interested. Here is a link to google docs for:

abstract, contents pages, etc.

the introduction

the conclusion

Let me know if these even work... And if you want to see any of the actual chapters - these are just opening and closing sections.

Photo: Senhor and Senhora Gonçalvez, by their functioning grain mill on the river Mouro. Interviewed for the thesis - which also gives a rough idea of how much electricity could be produced from their mill, while maintaining their flour milling service.

Peak Oil - recent reports need translating

Some recent publications about when peak oil is likely to change our lives for, pretty much ever, need to be shared, and translated around here into Portuguese and Galego...

Novos relatorios sobre pico de petroleo / devemos traduzir-los...

A report by the UK Energy Research Centre was presented to the APPGPOG in London this month, see here in condensed presentation format.

This study attempts to bring together the findings of over 500 experts' reports from around the world about oil production forecasts - how long we can maintain our current output, and even increase it to meet anticipated increased demand. It finds:

- the rate of decline (of oilfield output) is accelerating. To meet our oil habit in 2030 we would need to replace around two thirds of existing capacity, or, in other words, find a lot of new Saudi Arabia's by then.

- there is a "significant risk of "a peak in conventional oil production" by 2020. Many observers / oil industry geologists believe that peak production was actually July 2008 (at around 85m barrels per day). Regardless, anytime between now and 2020 is far too close for comfort means we need to be preparing communities and adapting technologies, entire infrastructure arrangements if we are to weather this storm.

The International Energy Agency's reassuring predictions is gave in last year's World Energy Outlook are still seriously detached from reality. However, we need to use this report as an useful reference: the voice of energy strategy for most Governments in the world.

Do people, local communities, city councils, regional and state Governments not know what is at stake if global oil production peaks? Surely they will have run the numbers and felt that chill going all over their body as they realize how desperate the situation could get. Especially for food production. Especially for people in developing countries who rely partially (sometimes completely) for our spare cash in aid funds to keep basic services and often food supplies flowing. Spare money for aid will be history. There will be no spare money. Developed economies will crash far harder as people loose jobs around the world, another recession following harder and deeper than the current blip. As their economies contract, it is hardly likely they will increase spending on aid in response to the multiple crises unfolding around the world as global food prices soar.

George Monbiot, as usual sums it all up eloquently in his recent article about peak oil and our food supply. He raises some great points, but rightly comes back to the issue of UK / EU / World food supply, about 90% of which is made, processed and shipped around with oil and gas. Reduce the amount of fuel, and the price will rise.

We need to get ready

Rocket stoves

A major development in efficient and way more healthy cooking systems the world over.



This film shows a massive production line of these things which could be great for selling to those that can afford them, or for humanitarian agencies to distribute in emergencies.
But for most communities in low income countries, buying a stove is out of the question. They just wouldn't have that of cash. So it would be better to bring the knowledge of how to make them from local materials, recycled metal from old cans, sand and local earth, etc. Very easy to make in fact.

This next link, shows step by step how it is done. These guys also have films on institutional stoves for camps and schools, etc.



The only problem in this film is that they say you need to make bricks first, in an oven at 900 degrees C. How many people have access to this kind of heat? I suppose anyone baking trees to make charcoal could try a few bricks in there, but the point is it adds a complicating factor, which we should avoid.

Paulo just built one on our land here(photos soon)without any bricks, bust using vermiculite insulation balls on the outside of the chimney (between chimney and outside container). OK, that's available cheaply here in Europe, so what could work in Robertsport, Liberia, for example?

The wood shed

Mary is studying architecture in England and likes to draw. And have ideas about building things. One day while trying to avoid any new projects she suggested a new wood store, an extension to the garage - to store the bits of wood we had cut from Donald's place a few weeks earlier. (Here's her dreaming up wood store designs stage left).

I like ideas like these and am suseptible to distractions of this nature at any time. Anyway, we do need somewhere to store wood, bikes and wetsuits when they are drying - out of the rain and out of the sun.

We started clearing the area - which took hours: more mega-brambles, tree roots, rocks. Why does moving rubble have to occupy so much of my life?

Then we realised that it was going to take weeks of labour to bring the level of the ground down a little, to be even, and so that you wouldn't whack your head every time you reached in to the shed on the lower end.

So we capitulated and called in the digger. We needed him anyway to dig a trench between garage and house (so water and power could be laid to garage. Mainly so we could wash our wetsuits at garage, before we dry them, but there are of course lots of other worthy reasons).

While we had him on site, we decided he might as well clear a huge pile of rocks and earth from the bottom of the quarry/climbing wall. Little did we know this would mean trucks upon trucks of rubble being moved out, and hours of costly gear on site. This wood store lark was becoming a monster! In the monster's defense, however, I would add that we have now reduced the huge pile of sticks and stones which once occupied the whole area to the right of the garage (see Nikita standing on this pile about a year ago, when we first started clearing the land)

Moreover, just about where Nikita is standing in that picture, we intend to build a dojo, tea room, training and stretching zone from bamboo and oak. One day.

Tired of waiting for the digger crew, Mary had long since returned to England to get back to school. But before she left we built up the structure on the garage to rest the new roof on. So it's half way there.

So Mary, now you can see we've got the level down and the site is ready. Come back - we'll build a wood/wetsuit store!
