Botijo, Electricity Free, Clay, Water Cooler

 

 

The Botijo is an amazing example of a low/no tech water cooler and it looks pretty good as well!

The Botijo is made of porous clay (with no glaze), when filled, the water permeates through to the outside and works like an evaporative cooler. The filtered water evaporates off the outer surface, cooling  the water inside, and the walls of  the Botijo and the immediate environment (put a small fan behind it and create a low tech, energy saving, personal evaporative cooling air conditioner!)

The Botijo has been used here in Spain for centuries as a water cooler and is still used to this day, it is a wonderful example of an inexpensive, nearly forgotten, ancient design and technology using evaporative cooling that just works!

The big spout is for filling the Botijo with water, the small spout is for drinking the cool water, Botijo etiquette demands the lips do not touch the drinking spout as it is usual that more than one person will be drinking from the Botijo. To save pouring cold water down the novice drinker’s front it probably makes sense to pour the water into a glass first!

This water cooler holds about 6.5 litres of water, the drier the heat the better for evaporative cooling. Fill it in the morning and all day long cool drinking water will be available with no cost in electricity.

My personal opinion is that the water tastes better after it has been in the Botijo for a while, and we have spring water! It is said that the minerals in the clay create that taste.

I tried a little experiment, I filled the Botijo water cooler and put it on a granite table in full sun, normally one would place it in the shade to aid evaporative cooling. When I returned a couple of hours later the granite top was just off hot to touch and yet the Botijo was cold to touch and the water was cool.

I am guessing the moisture around the lower half of the Botijo was due to the evaporative cooling of the heat of the granite top ‘pulling’ water through the clay to dissipate the heat. The small area directly under the Botijo was the only part of the granite top that was cool!

Cost and Comfort, the Benefit of ‘Green’ building

But wouldn’t your energy be better used going on a march to protest about world hunger.”

This was the reply to my girlfriend when her boss was trying to understand our ‘green’ attitude to life.

In fact to describe it as ‘green’ means nothing to us, our lifestyle is just our lifestyle within which we follow some core beliefs, those beliefs happen to be easily boxed and packaged as ‘green’ which is a shame as it somehow separates us from others who feel no desire to be ‘green’ and yet may share the same core beliefs.

So to anyone who may be looking at the way we are building here and the way we get our energy and are asking themselves why, I would like to explain why we do what we do without mentioning that word ‘green’ again (in this post!).

On the south side of home we have built the bathroom/toilet extension out of Cob. Cob is nothing more than clay, or in our case clay rich soil, sand and straw. The walls are half a meter thick which made it a year’s work so why do it that way?

A brick, or cement block building of that size would have taken a quarter of the time to build and far more acceptable and modern, why bother to use Cob?

So when you have a bath or a shower, especially in the winter, does your bathroom steam up? Are your walls wet with condensation, do you need to ventilate well to stop mould, would it feel cold in there if you had no heating?

Our Cob bathroom with a lime washed clay plaster, has no heating, the clay in the plaster and the walls regulates the moisture, absorbing it during bath time and slowly releasing in a natural drying process, though the room steams up there is never any wetness on the walls. The thick walls absorb the heat during the summer months and slowly release it during the winter, in the summer the room is cool, in the winter it is warm.

Of course one could achieve the same results with modern building techniques but at what cost?

The cost of building the cob walls of our bathroom was around 150 Euros ! Which is probably around a tenth of the cost of building with bricks.

All I actually did was to rearrange the dirt on the ground! I added sand straw and water and reshaped that dirt into a bathroom that is designed to work within the problems a bathroom can create.

On the North side of our house I am building the post and beam straw bale extension well documented here on the blog, but why straw bale?

The North side of our house gets the cold winds in the winter and little sun, we needed to build something that was well insulated. Straw bales have an insulation value of hmmmm well I would like to be able to tell you but apparently it is quite disputed what R value a straw bale has but suffice to say that straw bale walls are the equivalent of having a great deal of insulation in the walls!!

Placed off the ground on a stem wall and with a good roof straw bale houses over 100 years old are still sound and standing, showing no signs of deterioration.

The cost? Well we have used about 60 straw bales at 3 Euros each so at 180 Euros the walls have cost about a third of just what the insulation would have cost us to put inside the walls had we built using bricks!

So there we have it, cost and comfort, these are our priorities, our home will never be featured in Home and Gardens but it is hand made, fun to live in, warm, dry, cheap to run and not owned by a mortgage company. And one day next year when it is all finished I look forward to starting work on the land to try and produce our own food.

Practical Green Living (Casa Mandala)

Casa Mandala is situated in an olive finca (farm) on the edge of The Sierra Del Las Nieves, a  ’Parque Natural’  just outside  the small town of Alozaina.

Here the artizans and  artists, John and his partner Anna, are living the greenest of lifestyles one is likely to find, pushing the boundaries of reducing their standard of living in exchange for a beautiful  standard of life.

Here they recycle, create and build, all with an artistic theme and in touch with the flow of spirit and nature.

Though a skilled carpenter, John’s primary interest begins from his concept of living a ‘bill’ free life. Do away with bills to concentrate on life, this is expressed in his preferred method of building, Cob (cob is a mixture of clay or clay soil, sand and straw). His buildings are mainly a mixture of stone, cob, and recycled materials like pallets and washing machine doors (the glass ones!)

John and Anna accept visiting volunteers who come to learn about using cob in art, sculpture and structure, and are accomodated in one of the three small handmade chalets.

The earthen roofed chalet

The Yurt

At Casa Mandala there are no connected services, the electric comes from their 3 kilowatt solar photo voltaic system, the toilets are compost toilets and the water is collected rain water from the previous winter.

Here is the shower!

I asked John, if he was sure he wanted me to show the shower, my first impression was people seeing this may be put off wanting to come and stay but now I understand how much value one can get from Casa Mandala and it is all summed in this shower, I will explain this statement a bit further on.

Water is a precious resource, some of us are lucky to live at the source of a beautiful never ending stream of clean water, some of us are not so lucky. At Casa Mandala water is precious, it is collected in the winter and rationed through out the year, obviously during this time the water can go off but here John has an ingenious way of purifying it and storing it.

The water is left in theses jars for a couple of days, the sun heats the water and this low heat process purifies the water. The water is then transferred to dark glass jars for storage before being used.

So how does the shower represent the value at Casa Mandala?

To live this sustainable lifestyle, a lifestyle that is far more work than our average western lifestyle requires letting go of fear and replacing that fear with trust in who and what we really are beneath our facades. That open shower with one bucket of water strips away our facades, strips away our modesty, strips away our fear of not looking our best, it connects us back to nature and what nature can supply us with. It is natural and allows us to experience who and what we really are. After a hard day’s work of positive energy, a great learning experience and sweat, I would think what it takes to use that shower would cleanse and refresh the soul, the spirit and the body.

Practical Green Living (Molino Del Rey)

cave

Meditation cave

Above is one of the meditation spaces at Molino Del Rey, a centre for holistic retreats.

Molino Del Rey is the first post of hopefully many homes and buildings I hope to visit local to our home whose owners are trying to live a more sustainable green lifestyle.

The complex of buildings were originally two water mills that have been converted to provide a wonderful setting of meditation spaces, caves, streams and waterfalls.

stream

But what really interests me are these -

washing machines

Not the most beautiful or spiritual view the centre has to offer but these washing machines, made by LG, only use approximately 150 watt hours of electricity for an average wash. The main reason they use such little electricity is because they have no means of heating the water.

Though Molino is not off grid, if it were, any kind of electric water heating is a big drain on the power and battery capacity available, increasing the power requirements and expense of a photo voltaic solar power system.

But if you also have one of these on your roof ,

solar panels

The 1300 litre solar hot water panels use the sun to heat the water for up to 22 guests and staff and of course the washing machines. Even on a cloudy day.

The two washing machines linked to the hot water panels are a great way to save electricity, reduce the size of the electricity bill and help green the planet.

There is also a back up oil fired boiler, (not so green).

Green Living, the bad news!


How can there be any bad news to green living?

In my ‘Success’ trilogy (under the tag ‘Success’) I speak of how the pandering to the ego is destroying our selves our communities and our planet but I also believe that balancing ego success with heart success can repair the damage done.

I am not sure if it is because I am now a grumpy old man or if other’s share my view but I believe the various crisis that we are now experiencing, both financial and ecological are caused by human kind’s shallow spirituality caused by the growth of desire for ever more stuff!

With that said I thought it would be a good idea to visit other peoples green blogs to find out how they were living the green lifestyle so I could read and comment, hmmmm big mistake!!

All I could find was blogs selling green living, from soap to electric vehicles, admittedly there were some good blogs that consisted of regurgitated news on the subject but they themselves are supported by the advertising revenue that often looked quite dubious. (I am not speaking of green sites, just blogs)

I wanted to read what the people who have actually gone green had to say, I am not saying they are not out there, I just couldn’t find them, maybe the Google gods of search engines don’t value them, who knows.

So what does green living mean to you? Are you happy you can go online and buy it.

Of course you will not be buying an actual green way of life, you will just be buying into the same old ego success painted green.

Green living is living a sustainable life, so what standard of life would that be?

Well roughly, if you take the average USA citizen and reduce their standard of living by three quarters this reduction would not be quite enough to be sustainable, if you live in the UK and halved your standard of living, again this would not be enough to be sustainable, based on the whole world population having the same standard of living. http:///greenstory_view.php?storyid=1196

So what is one to do if one wants to not only live a green life but promote the benefits of a green lifestyle?

Well governments haven’t got a chance, no government is going to be voted into power on the bases that it is going to massively reduce your lifestyle.

Which unfortunately means most if not all the rich western governments are lying to their people when they talk about economics and growth.

So who really wants to sacrifice their lifestyle to return the earth to it’s natural colour.?

Well I do, and if you care to read on maybe you will as well.

It is not possible to sustain growth to a greener world, a greener world requires sustained shrinkage, in fact it is probably no longer just an option. If we cannot embrace sustained shrinkage it is likely the economic and environmental changes we are experiencing will force it upon us.

The fear of loss is greater than the loss you fear.

I believe the key to a green life is to seriously consider striving for heart success, the success of doing the right thing and not the ego success, the success of turning a blind eye to the right thing in order to have stuff and power.

We need to do more and use less but most of all we need to get out of the race to have the trinkets that say who we are and realise that all they say now is actually how spiritually shallow we are. To me wealth is not wrong but the trappings of wealth, for me, represent exploitation, somewhere along the line someone and something was exploited.

You cannot buy a green life, you have to live a green life as a whole.

Becoming a vegetarian (says the meat eater but I am trying!) is a wonderful example of doing more and using less, it takes planning and thought to eat well and be a vegetarian.

Any example I give you will be about making more effort and using less resources, that is the easy part, the hard part is to change peoples perception that success, real success, is not how much power and money you have or that you have a marble top kitchen, or the Ferrari parked outside.

Real success is sharing one’s wealth to resource others in your community, this is heart success, it is the key to the mindset that will help create a green life and combat the alternative which is the stealing by force of other’s precious resources, the darker alternative future.

For instance let us look at house wall and roof insulation, why haven’t all the houses built in the western world in the past 30 years had super insulated walls and roofs integrated at the design stage?

It is not because of cost or design factors it is because you can’t park insulation outside, or wear it to a party or show it off to your friends, unlike the success of double glazed windows which can be shown off that don’t save anywhere near as much energy as the unseen insulation

Green living is fun and I admit this post appears to be removing all the fun away from a green lifestyle but I am just trying to be real.

Now if your idea to go green is to buy an electric bike as an addition to all your stuff then you are not really helping anything other than your own ego, but if you buy the bike as a tool, an alternative means of travel it will give you the heart success I speak of, so much so that even on a cold wet evening sat at the traffic lights as the guy in the Ferrari pulls up next to you you may actually feel sorry for him!!
