13-year-old inventor cracks the secret of trees to revolutionize solar energy

http://themindunleashed.org/wp-content/uploads/2014/01/solarr.jpg
A 13-year-old boy named Aidan Dwyer has an idea that can vastly improve solar energy technology. His idea is so revolutionary that it might make flat panel solar designs extinct.
Aidan discovered a spiral mathematical formula in trees based on the Fibonacci sequence. When he recognized this design in the placement of tree branches, he began applying the secret knowledge to solar panel designs. His discovery could maximize solar panel sunlight collection in new, efficient ways.

DISCOVERING A PATTERN IN TREE TRUNKS


On a winter hiking trip, Aidan noticed something unique about tree branches. After collecting photographs of various trees, he began to see a pattern among the random display of branches and leaves. Aidan realized that the overall branch pattern of trees resembled a spiral. Furthermore, he found a mathematical pattern behind the spiral of branches. To investigate further, he began building test models.

USING THE FIBONACCI SEQUENCE TO MAXIMIZE SUNLIGHT COLLECTION

 
Upon investigating, Aidan discovered a pattern based on a number sequence invented by medieval mathematician Fibonacci. Fibonacci discovered a pattern when experimenting with a math puzzle. Through solving a problem about the rate at which rabbits reproduce over time, Fibonacci invented a sequence of numbers. Fibonacci invented a mathematical pattern, starting with zero and one. By adding two numbers to the series together, the new sum became the next number in the sequence. This sequence starts out with the numbers 1, 1, 2, 3, 5, 8, 13 and 21.
This Fibonacci sequence and its ratios appear in nature, in many forms of life. According to Aidan, examples of this pattern can be found in the seeds of a sunflower, systems of the human body and even galaxies in space.

Aidan found that tree trunks contain similar patterns based on the Fibonacci sequence.
According to Aidan, “Tree branches follow a Fibonacci formula.” He reports that, in an oak tree, branches are arranged in a two to five sequence. “Five branches spiral around the trunk two times to reach the same starting point on the trunk,” he reports.
The patterns that he found also include the elm tree, which follows a one to two pattern, and the beech tree, which follows a one to three pattern. He found a three to eight pattern in the willow tree and a five to one pattern in the branch arrangement of almond trees.

USING THE SPIRAL PATTERN FOR MAXIMUM EFFICIENCY IN SOLAR PANEL TECHNOLOGY

In trying to understand the meaning behind the pattern, Aidan hypothesized that the main goal of the leaves is to collect maximum sunlight for photosynthesis.
To test this hypothesis, Aidan created mini tree models with sunlight-collecting solar panels. He arranged the mini panels in a spiral pattern based on the Fibonacci sequence design he observed in the trees.
Logging data on voltage and current, Aidan ran tests on the spiral design and on a flat panel design for several months. his models below.
He found out that the Fibonacci solar panel design was extremely more efficient than flat panel designs. The spiral patterns collect, on average, 20 percent more open current voltage and absorbs 2.5 more hours of sunlight per day.
Even more exciting were his results during the winter solstice when the sun is at its lowest point in the sky. During this time, the Fibonacci design collected 50 percent more sunlight than flat panel designs!
“My results suggest that the Fibonacci pattern can improve solar panel arrays in several ways. It collects more sunlight when the sun is at a low angle in the sky. This is useful during winter months and in extreme latitudes,” Aidan explained.
He mentioned other benefits of the spiral design, saying that it will take up less room in urban areas, where space is limited. He also believes that the design would not collect as much rain and snow and be more weather-resistant than rooftop flat panel designs.

Natural Pools: A Beautiful Self-Sustaining Swimming Pool / Ecosystem for Your Yard

http://themindunleashed.org/wp-content/uploads/2014/05/natura.jpg
“Swimming in natural water is a delight to our senses. Your skin and hair feels soft and your eyes don’t sting. It seems as if, every cell in your body is telling you – this is the way swimming should be.” -David Pagan Butler
A Natural Swimming Pool is a swimming pool that has clear water without using chemicals. These pools rely entirely on the plants and animals to condition the water. This is so effective that this pool has been tested and shown to be of drinking water quality. Also, through the continual natural “cleaning process” the pool water never needs changing, saving water. It’s chemical free so it is healthy for people and wildlife alike. It’s truly wild Swimming at home. Here are some free plans to build your own: Mother Earth News

Plant Breeders Release First 'Open Source Seeds' /// Novel Open Source Seed Pledge aims to keep new vegetable and grain varieties free for all

Backers of the new Open Source Seed Initiative will pass out 29 new varieties of 14 different crops, including broccoli, carrots and kale, on Thursday.

A group of scientists and food activists is launching a campaignThursday to change the rules that govern seeds. They're releasing 29 new varieties of crops under a new "open source pledge" that's intended to safeguard the ability of farmers, gardeners and plant breeders to share those seeds freely.
It's inspired by the example of open source software, which is freely available for anyone to use but cannot legally be converted into anyone's proprietary product.
At an event on the campus of the University of Wisconsin, Madison, backers of the new Open Source Seed Initiative will pass out 29 new varieties of 14 different crops, including carrots, kale, broccoli and quinoa. Anyone receiving the seeds must pledge not to restrict their use by means of patents, licenses or any other kind of intellectual property. In fact, any future plant that's derived from these open source seeds also has to remain freely available as well.
Irwin Goldman, a vegetable breeder at the University of Wisconsin, Madison, helped organize the campaign. It's an attempt to restore the practice of open sharing that was the rule among plant breeders when he entered the profession more than 20 years ago.
"If other breeders asked for our materials, we would send them a packet of seed, and they would do the same for us," he says. "That was a wonderful way to work, and that way of working is no longer with us."
These days, seeds are intellectual property. Some are patented as inventions. You need permission from the patent holder to use them, and you're not supposed to harvest seeds for replanting the next year.
Even university breeders operate under these rules. When Goldwin creates a new variety of onions, carrots or table beets, a technology-transfer arm of the university licenses it to seed companies.
This brings in money that helps pay for Goldman's work, but he still doesn't like the consequences of restricting access to plant genes — what he calls germplasm. "If we don't share germplasm and freely exchange it, then we will limit our ability to improve the crop," he says.
Sociologist Jack Kloppenburg, also at the University of Wisconsin, has been campaigning against seed patents for 30 years. His reasons go beyond 
Goldman's.
He says turning seeds into private property has contributed to the rise of big seed companies that in turn promote ever-bigger, more specialized farms. "The problem is concentration, and the narrow set of uses to which the technology and the breeding are being put," he says.
Kloppenburg says one important goal for this initiative is simply to get people thinking and talking about how seeds are controlled. "It's to open people's minds," he says. "It's kind of a biological meme, you might say: Free seed! Seed that can be used by anyone!"
The practical impact of the Open Source Seed Initiative on farmers and gardeners, however, may be limited. Even though anyone can use such seed, most people probably won't be able to find it.
The companies that dominate the seed business probably will keep selling their own proprietary varieties or hybrids. There's more money to be made with those seeds.
Most commercial vegetable seeds are hybrids, which come with a kind of built-in security lock; if you replant seed from a hybrid, you won't get exactly the same kind of plant. (For this reason, some seed companies don't bother getting patents on their hybrids.)
John Shoenecker, director of intellectual property for the seed company HM Clause and the incoming president of the American Seed Trade Association, says his company may avoid using open source seed to breed new commercial varieties "because then we'd ... have limited potential to recoup the investment." That's because the offspring of open source seeds would have to be shared as well, and any other seed company could immediately sell the same variety.
The initiative is probably more significant for plant breeders, especially at universities. Goldman says he expects many plant breeders at universities to join the open source effort.
Meanwhile, two small seed companies that specialize in selling to organic farmers — High Mowing Organic Seeds in Hardwick, Vt., and Wild Garden Seed in Philomath, Ore., are adding some open source seeds to their catalogs this year

Novel Open Source Seed Pledge aims to keep new vegetable and grain varieties free for all

This week, scientists, farmers and sustainable food systems advocates will gather on the University of Wisconsin-Madison campus to celebrate an unusual group of honored guests: 29 new varieties of broccoli, celery, kale, quinoa and other vegetables and grains that are being publicly released using a novel form of ownership agreement known as the Open Source Seed Pledge.
The pledge, which was developed through a UW-Madison-led effort known as the Open Source Seed Initiative, is designed to keep the new seeds free for all people to grow, breed and share for perpetuity, with the goal of protecting the plants from patents and other restrictions down the line.
"These vegetables are part of our common cultural heritage, and our goal is to make sure these seeds remain in the public domain for people to use in the future," says UW-Madison horticulture professor and plant breeder Irwin Goldman, who helped write the pledge.
Goldman will release two carrot varieties he developed-named Sovereign and Oranje in the spirit of the event-at a public ceremony Thursday's public ceremony, which is set for 11 a.m. on the front lawn of the UW-Madison's Microbial Sciences Building, 1550 Linden Drive.
The Open Source Seed Initiative (OSSI) was established in 2011 by public plant breeders, farmers, non-governmental organization staff and sustainable food systems advocates from around the nation concerned about the decreasing availability of plant germplasm-seeds-for public plant breeders and farmer-breeders to work with.
Many of the seeds for our nation's big crop plants – field corn and soybeans – are already restricted through patents, licenses and other forms of intellectual property protection. Increasingly, this is happening to vegetable, fruit and small grain seeds. Members of OSSI worry that this trend could lead to a time when there's no longer any valuable plant germplasm available for public use.
“These vegetables are part of our common cultural heritage, and our goal is to make sure these seeds remain in the public domain for people to use in the future.”
Irwin Goldman
"Already, many public breeders don't have the freedom to operate. They can't do what they want to do as often as they would like," says Jack Kloppenburg, UW-Madison professor of community and environmental sociology and author of "First the Seed," who has provided much of the guiding vision for the OSSI group.
Early on, inspired by the open source software community, which freely shares and collaborates to improve their products, OSSI members starting exploring how to develop open source licenses for seeds-but came upon numerous roadblocks along the way.
This spring, eager to get things moving forward again, Goldman and Kloppenburg convinced many in the group to embrace the simplest option they had discussed: the Open Source Seed Pledge.
Unlike the comprehensive open source licenses the OSSI group originally tried to develop, the pledge is very concise. It's so short it will be printed on all OSSI seed packets.
"It's almost like a haiku," says Goldman. "It basically says these seeds are free to use in any way you want. They can't be legally protected. Enjoy them."
By opening the packet, a person signals their commitment to keep those seeds-and any future plant derivatives bred using them-in the public domain.
"It creates a parallel system, a new space where breeders and farmers can share seeds," says Kloppenburg. "And, because it applies to derivatives, it makes for an expanding pool of germplasm that any plant breeder can freely use."
Seed packets
Seed packets are ready for distribution as part of the initiative.

Even with the new pledge available, Goldman, who breeds beets, carrots and onions, still plans to license many of his new varieties the traditional way through the Wisconsin Alumni Research Foundation(WARF), the patenting and licensing arm of the UW-Madison, which has been supportive of his interest in open source seeds. It depends on the situation, he notes.
If Goldman develops a new variety that he'd like to see large seed companies incorporate into their breeding programs-for instance, a new carrot with improved disease resistance-he'll most likely work with WARF to release the seeds using a traditional license.
But Goldman is thrilled that he now has an alternative option, for when he wants to share new varieties with fellow public plant breeders-or small seed companies.
"There are economic opportunities here," he notes. "You can sell these open source seeds just like you'd sell any other seeds. The difference is that the recipients can actually do stuff with them, which is kind of fun."
Because the Open Source Seed Pledge has not been tested, it's unclear what its legacy may be. For now, OSSI members are enjoying their recent accomplishments and hoping for the best.
"Who knows what will happen, but even if the pledge does nothing more than help raise awareness about what's going on with seeds, that's progress," says Goldman.
And the group hopes for much more.
Some would like to finish the job of developing a more comprehensive open source license for seeds. Others want to bring international partners on board.
"This is the birth of a movement," says Kloppenburg. "Open source means sharing, and shared seed can be the foundation of a more sustainable and more just food system."

Naomi Klein: How science is telling us all to revolt

Is our relentless quest for economic growth killing the planet? Climate scientists have seen the data – and they are coming to some incendiary conclusions.



In December 2012, a pink-haired complex systems researcher named Brad Werner made his way through the throng of 24,000 earth and space scientists at the Fall Meeting of the American Geophysical Union, held annually in San Francisco. This year’s conference had some big-name participants, from Ed Stone of Nasa’s Voyager project, explaining a new milestone on the path to interstellar space, to the film-maker James Cameron, discussing his adventures in deep-sea submersibles.
But it was Werner’s own session that was attracting much of the buzz. It was titled “Is Earth F**ked?” (full title: “Is Earth F**ked? Dynamical Futility of Global Environmental Management and Possibilities for Sustainability via Direct Action Activism”).
Texas.











Standing at the front of the conference room, the geophysicist from the University of California, San Diego walked the crowd through the advanced computer model he was using to answer that question. He talked about system boundaries, perturbations, dissipation, attractors, bifurcations and a whole bunch of other stuff largely incomprehensible to those of us uninitiated in complex systems theory. But the bottom line was clear enough: global capitalism has made the depletion of resources so rapid, convenient and barrier-free that “earth-human systems” are becoming dangerously unstable in response. When pressed by a journalist for a clear answer on the “are we f**ked” question, Werner set the jargon aside and replied, “More or less.”
There was one dynamic in the model, however, that offered some hope. Werner termed it “resistance” – movements of “people or groups of people” who “adopt a certain set of dynamics that does not fit within the capitalist culture”. According to the abstract for his presentation, this includes “environmental direct action, resistance taken from outside the dominant culture, as in protests, blockades and sabotage by indigenous peoples, workers, anarchists and other activist groups”.
Serious scientific gatherings don’t usually feature calls for mass political resistance, much less direct action and sabotage. But then again, Werner wasn’t exactly calling for those things. He was merely observing that mass uprisings of people – along the lines of the abolition movement, the civil rights movement or Occupy Wall Street – represent the likeliest source of “friction” to slow down an economic machine that is careening out of control. We know that past social movements have “had tremendous influence on . . . how the dominant culture evolved”, he pointed out. So it stands to reason that, “if we’re thinking about the future of the earth, and the future of our coupling to the environment, we have to include resistance as part of that dynamics”. And that, Werner argued, is not a matter of opinion, but “really a geophysics problem”.
Plenty of scientists have been moved by their research findings to take action in the streets. Physicists, astronomers, medical doctors and biologists have been at the forefront of movements against nuclear weapons, nuclear power, war, chemical contamination and creationism. And in November 2012,Nature published a commentary by the financier and environmental philanthropist Jeremy Grantham urging scientists to join this tradition and “be arrested if necessary”, because climate change “is not only the crisis of your lives – it is also the crisis of our species’ existence”.
Some scientists need no convincing. The godfather of modern climate science, James Hansen, is a formidable activist, having been arrested some half-dozen times for resisting mountain-top removal coal mining and tar sands pipelines (he even left his job at Nasa this year in part to have more time for campaigning). Two years ago, when I was arrested outside the White House at a mass action against the Keystone XL tar sands pipeline, one of the 166 people in cuffs that day was a glaciologist named Jason Box, a world-renowned expert on Greenland’s melting ice sheet.
 “I couldn’t maintain my self-respect if I didn’t go,” Box said at the time, adding that “just voting doesn’t seem to be enough in this case. I need to be a citizen also.”
This is laudable, but what Werner is doing with his modelling is different. He isn’t saying that his research drove him to take action to stop a particular policy; he is saying that his research shows that our entire economic paradigm is a threat to ecological stability. And indeed that challenging this economic paradigm – through mass-movement counter-pressure – is humanity’s best shot at avoiding catastrophe.
That’s heavy stuff. But he’s not alone. Werner is part of a small but increasingly influential group of scientists whose research into the destabilisation of natural systems – particularly the climate system – is leading them to similarly transformative, even revolutionary, conclusions. And for any closet revolutionary who has ever dreamed of overthrowing the present economic order in favour of one a little less likely to cause Italian pensioners to hang themselves in their homes, this work should be of particular interest. Because it makes the ditching of that cruel system in favour of something new (and perhaps, with lots of work, better) no longer a matter of mere ideological preference but rather one of species-wide existential necessity.
Leading the pack of these new scientific revolutionaries is one of Britain’s top climate experts, Kevin Anderson, the deputy director of the Tyndall Centre for Climate Change Research, which has quickly established itself as one of the UK’s premier climate research institutions. Addressing everyone from the Department for International Development to Manchester City Council, Anderson has spent more than a decade patiently translating the implications of the latest climate science to politicians, economists and campaigners. In clear and understandable language, he lays out a rigorous road map for emissions reduction, one that provides a decent shot at keeping global temperature rise below 2° Celsius, a target that most governments have determined would stave off catastrophe.
But in recent years Anderson’s papers and slide shows have become more alarming. Under titles such as “Climate Change: Going Beyond Dangerous . . . Brutal Numbers and Tenuous Hope”, he points out that the chances of staying within anything like safe temperature levels are diminishing fast.
With his colleague Alice Bows, a climate mitigation expert at the Tyndall Centre, Anderson points out that we have lost so much time to political stalling and weak climate policies – all while global consumption (and emissions) ballooned – that we are now facing cuts so drastic that they challenge the fundamental logic of prioritising GDP growth above all else.
Anderson and Bows inform us that the often-cited long-term mitigation target – an 80 per cent emissions cut below 1990 levels by 2050 – has been selected purely for reasons of political expediency and has “no scientific basis”. That’s because climate impacts come not just from what we emit today and tomorrow, but from the cumulative emissions that build up in the atmosphere over time. And they warn that by focusing on targets three and a half decades into the future – rather than on what we can do to cut carbon sharply and immediately – there is a serious risk that we will allow our emissions to continue to soar for years to come, thereby blowing through far too much of our 2° “carbon budget” and putting ourselves in an impossible position later in the century.
Which is why Anderson and Bows argue that, if the governments of developed countries are serious about hitting the agreedupon international target of keeping warming below 2° Celsius, and if reductions are to respect any kind of equity principle (basically that the countries that have been spewing carbon for the better part of two centuries need to cut before the countries where more than a billion people still don’t have electricity), then the reductions need to be a lot deeper, and they need to come a lot sooner.
To have even a 50/50 chance of hitting the 2° target (which, they and many others warn, already involves facing an array of hugely damaging climate impacts), the industrialised countries need to start cutting their greenhouse-gas emissions by something like 10 per cent a year – and they need to start right now. But Anderson and Bows go further, pointing out that this target cannot be met with the array of modest carbonpricing or green-tech solutions usually advocated by big green groups. These measures will certainly help, to be sure, but they are simply not enough: a 10 per cent drop in emissions, year after year, is virtually unprecedented since we started powering our economies with coal. In fact, cuts above 1 per cent per year “have historically been associated only with economic recession or upheaval”, as the economist Nicholas Stern put it in his 2006 report for the British government.
 Even after the Soviet Union collapsed, reductions of this duration and depth did not happen (the former Soviet countries experienced average annual reductions of roughly 5 per cent over a period of ten years). They did not happen after Wall Street crashed in 2008 (wealthy countries experienced about a 7 per cent drop between 2008 and 2009, but their CO2 emissions rebounded with gusto in 2010 and emissions in China and India had continued to rise). Only in the immediate aftermath of the great market crash of 1929 did the United States, for instance, see emissions drop for several consecutive years by more than 10 per cent annually, according to historical data from the Carbon Dioxide Information Analysis Centre. But that was the worst economic crisis of modern times.
If we are to avoid that kind of carnage while meeting our science-based emissions targets, carbon reduction must be managed carefully through what Anderson and Bows describe as “radical and immediate de-growth strategies in the US, EU and other wealthy nations”. Which is fine, except that we happen to have an economic system that fetishises GDP growth above all else, regardless of the human or ecological consequences, and in which the neoliberal political class has utterly abdicated its responsibility to manage anything (since the market is the invisible genius to which everything must be entrusted).
So what Anderson and Bows are really saying is that there is still time to avoid catastrophic warming, but not within the rules of capitalism as they are currently constructed. Which may be the best argument we have ever had for changing those rules.
In a 2012 essay that appeared in the influential scientific journal Nature Climate Change, Anderson and Bows laid down something of a gauntlet, accusing many of their fellow scientists of failing to come clean about the kind of changes that climate change demands of humanity. On this it is worth quoting the pair at length:
 . . . in developing emission scenarios scientists repeatedly and severely underplay the implications of their analyses. When it comes to avoiding a 2°C rise, “impossible” is translated into “difficult but doable”, whereas “urgent and radical” emerge as “challenging” – all to appease the god of economics (or, more precisely, finance). For example, to avoid exceeding the maximum rate of emission reduction dictated by economists, “impossibly” early peaks in emissions are assumed, together with naive notions about “big” engineering and the deployment rates of low-carbon infrastructure. More disturbingly, as emissions budgets dwindle, so geoengineering is increasingly proposed to ensure that the diktat of economists remains unquestioned.
In other words, in order to appear reasonable within neoliberal economic circles, scientists have been dramatically soft-peddling the implications of their research. By August 2013, Anderson was willing to be even more blunt, writing that the boat had sailed on gradual change. “Perhaps at the time of the 1992 Earth Summit, or even at the turn of the millennium, 2°C levels of mitigation could have been achieved through significant evolutionary changes within the political and economic hegemony. But climate change is a cumulative issue! Now, in 2013, we in high-emitting (post-)industrial nations face a very different prospect. Our ongoing and collective carbon profligacy has squandered any opportunity for the ‘evolutionary change’ afforded by our earlier (and larger) 2°C carbon budget. Today, after two decades of bluff and lies, the remaining 2°C budget demands revolutionary change to the political and economic hegemony” (his emphasis).
We probably shouldn’t be surprised that some climate scientists are a little spooked by the radical implications of even their own research. Most of them were just quietly doing their work measuring ice cores, running global climate models and studying ocean acidification, only to discover, as the Australian climate expert and author Clive Hamilton puts it, that they “were unwittingly destabilising the political and social order”.
But there are many people who are well aware of the revolutionary nature of climate science. It’s why some of the governments that decided to chuck their climate commitments in favour of digging up more carbon have had to find ever more thuggish ways to silence and intimidate their nations’ scientists. In Britain, this strategy is becoming more overt, with Ian Boyd, the chief scientific adviser at the Department for Environment, Food and Rural Affairs, writing recently that scientists should avoid “suggesting that policies are either right or wrong” and should express their views “by working with embedded advisers (such as myself), and by being the voice of reason, rather than dissent, in the public arena”.
If you want to know where this leads, check out what’s happening in Canada, where I live. The Conservative government of Stephen Harper has done such an effective job of gagging scientists and shutting down critical research projects that, in July 2012, a couple thousand scientists and supporters held a mock-funeral on Parliament Hill in Ottawa, mourning “the death of evidence”. Their placards said, “No Science, No Evidence, No Truth”.
But the truth is getting out anyway. The fact that the business-as-usual pursuit of profits and growth is destabilising life on earth is no longer something we need to read about in scientific journals. The early signs are unfolding before our eyes. And increasing numbers of us are responding accordingly: blockading fracking activity in Balcombe; interfering with Arctic drilling preparations in Russian waters (at tremendous personal cost); taking tar sands operators to court for violating indigenous sovereignty; and countless other acts of resistance large and small. In Brad Werner’s computer model, this is the “friction” needed to slow down the forces of destabilisation; the great climate campaigner Bill McKibben calls it the “antibodies” rising up to fight the planet’s “spiking fever”.
It’s not a revolution, but it’s a start. And it might just buy us enough time to figure out a way to live on this planet that is distinctly less f**ked.

TED TV: Ron Finley : Een guerilla-tuinier in South Central L.A.



“If kids grow kale, kids eat kale. If they grow tomatoes, they eat tomatoes. But when none of this is presented to them, if they're not shown how food affects the mind and the body, they blindly eat whatever you put in front of them.”





Artist and designer Ron Finley couldn’t help but notice what was going on in his backyard. “South Central Los Angeles,” he quips, “home of the drive-thru and the drive-by.” And it's the drive-thru fast-food stands that contribute more to the area’s poor health and high mortality rate, with one in two kids contracting a curable disease like Type 2 diabetes.

Finley’s vision for a healthy, accessible “food forest” started with the curbside veggie garden he planted in the strip of dirt in front of his own house. When the city tried to shut it down, Finley’s fight gave voice to a larger movement that provides nourishment, empowerment, education -- and healthy, hopeful futures -- one urban garden at a time.

Mark Boyle : The man who lives without money



 
Irishman Mark Boyle tried to live life with no income, no bank balance and no spending. Here’s how he finds it.

If someone told me seven years ago, in my final year of a business and economics degree, that I’d now be living without money, I’d have probably choked on my microwaved ready meal. The plan back then was to get a ‘good’ job, make as much money as possible, and buy the stuff that would show society I was successful.

For a while I did it – I had a fantastic job managing a big organic food company; had myself a yacht on the harbour. If it hadn’t been for the chance purchase of a video called Gandhi, I’d still be doing it today. Instead, for the last fifteen months, I haven’t spent or received a single penny. Zilch.
The change in life path came one evening on the yacht whilst philosophising with a friend over a glass of merlot. Whilst I had been significantly influenced by the Mahatma’s quote “be the change you want to see in the world”, I had no idea what that change was up until then. We began talking about all major issues in the world – environmental destruction, resource wars, factory farms, sweatshop labour – and wondering which of these we would be best devoting our time to. Not that we felt we could make any difference, being two small drops in a highly polluted ocean.

But that evening I had a realisation. These issues weren’t as unrelated as I had previously thought – they had a common root cause. I believe the fact that we no longer see the direct repercussions our purchases have on the people, environment and animals they affect is the factor that unites these problems.

The degrees of separation between the consumer and the consumed have increased so much that it now means we’re completely unaware of the levels of destruction and suffering embodied in the ‘stuff’ we buy.

Very few people actually want to cause suffering to others; most just don’t have any idea that they directly are. The tool that has enabled this separation is money, especially in its globalised format.
Take this for an example: if we grew our own food, we wouldn’t waste a third of it as we do today.
If we made our own tables and chairs, we wouldn’t throw them out the moment we changed the interior décor.

If we had to clean our own drinking water, we probably wouldn’t shit in it.
So to be the change I wanted to see in the world, it unfortunately meant I was going to have to give up money, which I decided to do for a year initially. So I made a list of the basics I’d need to survive.

I adore food, so it was at the top. There are four legs to the food-for-free table: foraging wild food, growing your own, bartering and using waste grub, of which there far too much.
On my first day I fed 150 people a three course meal with waste and foraged food. Most of the year I ate my own crops though and waste only made up about five per cent my diet. I cooked outside – rain or shine – on a rocket stove.

Next up was shelter. So I got myself a caravan from Freecycle, parked it on an organic farm I was volunteering with, and kitted it out to be off the electricity grid. I’d use wood I either coppiced or scavenged to heat my humble abode in a wood burner made from an old gas bottle, and I had a compost loo to make ‘humanure’ for my veggies.

I bathed in a river, and for toothpaste I used washed up cuttlefish bone with wild fennel seeds, an oddity for a vegan. For loo roll I’d relieve the local newsagents of its papers (I once wiped my arse with a story about myself); it wasn’t double quilted but it quickly became normal. To get around I had a bike and trailer, and the 55 km commute to the city doubled up as my gym subscription. For lighting I’d use beeswax candles.

Many people label me an anti-capitalist. Whilst I do believe capitalism is fundamentally flawed, requiring infinite growth on a finite planet, I am not anti anything. I am pro-nature, pro-community and pro-happiness. And that’s the thing I don’t get – if all this consumerism and environmental destruction brought happiness, it would make some sense. But all the key indicators of unhappiness – depression, crime, mental illness, obesity, suicide and so on are on the increase. More money it seems, does not equate to more happiness.

Ironically, I have found this year to be the happiest of my life. I’ve more friends in my community than ever, I haven’t been ill since I began, and I’ve never been fitter. I’ve found that friendship, not money, is real security. That most western poverty is spiritual. And that independence is really interdependence.

Could we all live like this tomorrow? No. It would be a catastrophe, we are too addicted to both it and cheap energy, and have managed to build an entire global infrastructure around the abundance of both. But if we devolved decision making and re-localised down to communities of no larger than 150 people, then why not? For over 90 per cent of our time on this planet, a period when we lived much more ecologically, we lived without money. Now we are the only species to use it, probably because we are the species most out of touch with nature.

People now often ask me what is missing compared to my old world of lucre and business. Stress. Traffic-jams. Bank statements. Utility bills. Oh yeah, and the odd pint of organic ale with my mates down the local.
