A comprehensive round up of this monthâ€™s most important news stories and what they mean to us, the general public
welcome BREATHE IN, BREATHE OUT Occasionally things happen that remind us why we publish this magazine, which, we hope, helps make common sense of the science behind our journey to a carbon neutral world. Things like US Republican House Representatives Ed Orcutt’s recent outburst on carbon dioxide emissions in which he suggested that contrary to scientific opinion, the real culprits are cyclists. And that as a punishment for their selfish, earth-warming activities they should be taxed. Orcutt went on to say that he believes bikes are bad for the environment because they cause cyclists to have “an increased heart rate and respiration” which in turn causes them to give off more carbon dioxide than your average sedentary motorist. (Let alone the cumulative effect on global temperatures of all that sweat dripping onto the road). Although to be fair, he did admit to not having done any “emissions analysis” as such. More of a hunch then it would seem. Which would be fine if he was just some cranky old bloke perched on a stool in a cozy diner somewhere ranting his inaccuracies to his long-suffering cronies. But a member of the US House of Representatives? Scary to say the least. As a popular US television show would be apt to ask,, ‘is this man smarter than a 5th grader?’ Fortunately his gross lack of scientific understanding didn’t go unnoticed and after a barrage of emails (mainly from 5th graders perhaps?) he was forced to do a little ‘analysis’ of the facts and eventually retracted his original statement by saying that although he has always recognized that bicycling emits less carbon than cars he did a poor job of indicating that in his original statement. “My point was that by not driving a car, a cyclist was not necessarily having a zero-carbon footprint. In looking back, it was not a point worthy of even mentioning so, again, I apologize.” As my grandmother would have said, “For the love of Mike and all things sacred…” 4

OUR TOP 10 GREEN GADGETS 10. Water-Powered Clocks A clock which only requires a little tap water to power your alarm in the morning. By doing something really clever with electrolytic cells and water electrons, this stylish Hammacher and Schlemmer product creates its own electricity supply. One refill lasts about 12 weeks.
9. Efergy Shower Timer and Alarm The average shower takes between 5 and 8 gallons of water from your tank, more if you’re the sort of person who’s apt to wander off with the fairies as soon as the steam starts rising. A wasteful habit you’ll be able to keep a closer eye on with the help of this Effergy timer and alarm thingy. It somehow figures out how much water you’re getting through as it happens and then bleeps you back to consciousness when you’ve used your allocated amount of water.
8. Hiriko Folding Electric Car Not one for the purists perhaps but this rather neat folding car deserves a mention because its just so bloody diddy. And it works! Essentially the Hiriko is a folding two-seat urban electric car being developed by the Hiriko Driving Mobility consortium in the Basque Country. Specs: Weight: 500kg Range: 120km Top Speed: 50kmh Length: 2.5m Price (when they start selling it later this year): 12,500 euros plus battery lease. Brilliant for rubbish parker too. Just drive straight in, no diddling around whatsoever. Bound to be popular with growing number of car sharing communities reckon.
easy-green 7. The Airnergy Wifi Charger A device that harvests all those wifi signals we have pinging around the place these days and converts them into usable electric energy! An odd concept yes, but true by all accounts. It can charge itself while also providing power for cellphones and other gadgets whenever you’re in a wi-fi hotspot. Not quite sure what effect it has on the wi-fi, but we’re prepared to overlook that research for the time being.
6. Power-generating turnstiles An idea that could have come straight out of a George Orwell novel true, but wonderfully simple and somehow appropriate. Conceived by the Viva Design Team of Guangdong University of Technology, the Green Pass turnstile at subway entrances produces electricity whenever someone passes through. The energy is used to power the card readers, coin counters and other electronic services. Neat and simple, if a little ‘mouse in a wheel-ish’. 8
5. Treelights Taiwanese scientists have come up with a way of harmlessly helping ordinary trees retain solar power during the day and re-emit it slowly during the night in the form of fluorescent light. By injecting nanoparticles of gold into plant leaves the scientists were able to affect their chlorophyll production systems, or something of that sort, resulting in the worldâ€™s first glowing trees and a possible alternative to expensive street lighting. A bit on the Avatar side of things, but eerily attractive donâ€™t you think?
4. The Solar Camera Strap Photographers are used to lugging equipment around with them, including a heavy camera strap. So why not make that strap with built in solar panels and use them to power all those other gizmos and gadgets? So thought designer Weng Jie, who has done just that.
3. The Spincycle Pedal-Powered Washing Machine When Sheffiled Hallam University graduate Richard Hewitt visited a childrenâ€™s orphanage in Barundi, he was given the task of washing 30 loads of kids clothes by hand. Something which, as a student, would normally have involved a quick slope down to the local launderette and a bucketful of change for the drier. So doing it all by hand was understandably alien, let alone physically easy. So using the brain he was blessed with and the privilege of a good education, Richard set about inventing a mini-washing machine that could be powered by a simple bicycle. Hence the Spincycle, the fully-functioning end product of his labours. The Spincycle uses a relatively small amount of water compared to a regular washing machine and considerably less again than the amount of water required by hand washing. It also has the advantage of functioning as a micro-business (everyone needs their clothes washed some time) to provide an income to those able to get their hands on one. Or rather, legs.
2. The Life Sack â€“ A Grain Sack That Doubles Up As A Water Purifier Kit Using Solar Water Disinfection Process (SODIS) technology even a simple grain sack can have future. A future, thanks to Korean designers Jung Uk Park, Myeong Hoon Lee, and Dae Youl Lee, as a water purifier. After the grain is removed from the sack a simple water purifying kit is added enabling it to render harmless by ultraviolet zapping the many harmful microorganisms and bacterium found in the water supplies in poorer parts of the world.
1. 3D Printers 3D printers are big, really big. Not literally, but big in the sense of the impact they are going to have on traditional manufacturing methods. Based on what is known as additive manufacturing — the opposite of the current ‘subtractive’ manufacturing methods in which an object is created by whittling away at pieces of a block of material – the object is instead created by building up tiny pieces of it from scratch. “Three-dimensional printing makes it as cheap to create single items as it is to produce thousands and thus undermines economies of scale. It may have as profound an impact on the world as the coming of the factory did…. Just as nobody could have predicted the impact of the steam engine in 1750 — or the printing press in 1450, or the transistor in 1950 — it is impossible to foresee the long-term impact of 3D printing. But the technology is coming, and it is likely to disrupt every field it touches.” (The Economist) And, best of all perhaps, when the printer itself starts to get a bit old, you’ll be able to use it to create its own successor. Let’s just hope they don’t start doing that all by themselves one day. Will Smith might be busy and then what?
INTO THE UNKNOWN Is Nuclear Fusion Really The Holy Grail Of Energy?
Right now in the south of France several countries are contributing to the construction of an 18-billion euro experiment to find out if we can produce our power in the same way the sun does. And all the other stars out there for that matter. Power which supporters of the scientific theory argue would come without nuclear waste, no carbon dioxide emissions and no chance of a the sort of nuclear accidents and meltdowns recently witnessed at nuclear fission power plants like Fukishima. That’s ‘fission’ not ‘fusion’, an important distinction. The proposed ‘fusion’ facility, at Caderache, grandly referred to as the International Thermonuclear
Experimental Reactor (ITER), is being funded by the European Union, the United States, China, South Korea, Japan, India and the Russian Federation. Construction is due to be complete by 2020, with the first test reaction planned for later that year. The process of nuclear fusion, so far only mastered for very brief moments in laboratory conditions, involves fusing atoms together at temperatures as high as 150 million degrees centigrade (ten times the heat of the heat of the sun) until they turn into what is known as the 4th stage of matter, or plasma. This super hot plasma gives off huge amounts of energy. At the ITER Project the
plan is to fuse the hydrogen isotope deuterium (obtainable from water) and the lithium derived radioactive isotope tritium, the end result of which should be a helium nucleus, a neutron and oodles and oodles of energy. Or at least thatâ€™s how the theory goes. It is hoped that fusion reactors will be able to produce 7 billion kilowatthours of energy per year, a little less than the output of nuclear fission reactors. Achieving the required temperatures for fusion to take place will require large amounts of energy in itself, but scientists at ITER are confident that the energy output will be tenfold the
nuclear fusion input. And more importantly, with only very minimal nuclear waste. The ITER experiment will be the first time nuclear fusion has ever been attempted on a large scale and its supporters are keen to point out that the process behind it differs radically from nuclear fission which requires particles to be separated in a reaction which also produces huge amounts of power, but always with a far higher inherent risk of meltdown and the inevitable problem of longlife nuclear waste. The hydrogen isotopes deuterium and tritium were chosen because they are widely available and because they donâ€™t have a long-term legacy of radioactive waste.

The main driver behind the quest for successful nuclear fusion is seen by many to be the funding countriesâ€™ desire to achieve energy independence as supplies of fossil fuels begin to dry up in the next 20 or 30 years. At current rates, the European Union for example, is expected to import 70% of its energy requirements by 2030. In the shorter term the ITER project is expected to produce thousands of jobs not only in France but also in other partnering countries such as Spain and Japan.
The project is not without its detractors however. Just recently a demonstration organized by a French activist network called ‘Sortir du Nucléaire’ (End Nuclear) in Paris attracted 4,000 protestors and a fair degree of confusing press coverage, in and around the quagmire territory of fusion v fission. Most of the genuine protest seemed to centre not on the possible dangers of the process of fusion itself, but the amount of money being devoted to it. “While entertaining the myth of an ever-abundant energy source in a few decades, ITER is diverting attention from real solutions to energy problems like renewable resources and energy conservation,” said Charlotte Mijeon, of Sortir du Nucléaire.

A contention that was countered by ITER’s head of communications Michel Claessens. “The money isn’t actually a huge issue for participating nations, nor is it being taken from sustainable energy research. It’s spread out across 34 countries over ten years of construction. So as far as each state is concerned, it’s a relatively modest sum,” he said. “The overall goal of ITER is to provide a long-term solution to increasing energy shortages,” added Aris Apollonatos of Fusion for Energy, the group overseeing the EU’s participation in ITER. “ITER participants are hoping that the research will be invaluable for the future when carbon and petroleum become scarce. Renewable energy sources like wind
and water may not be enough, but nuclear energy as it is currently creates too much pollution and risk. With fusion, that could change. Fusion, and by consequence ITER, is part of the long-term sustainable energy mix given the fact that it does not emit any carbon dioxide.” The key questions being it would appear: How much of our time, effort and resources should we devote to the development of nuclear fusion? Is it really as safe as they say it is? Should we not be investing all this money in clean energy technology that we already have? Will developing a
reliance on the ‘prospect’ of success with nuclear fusion, which it has to be remembered has never been achieved at scale before, lull us into a false sense of security? Thus diverting us from the real and immediate task of dealing with our transition to a lowcarbon world. “Oh don’t worry dear, they’re bound to crack the nuclear fusion riddle some day soon. Now put on your swimming costume, we’re going to the shops.” Or as somebody put it recently, can putting too much faith in the success of experimental plants like ITER not be likened to a dieter who carries on scoffing chocolate and cakes in the certain knowledge that one day soon scientists will discover a pain-free miracle diet pill?

TOO HOT TO HANDLE? Fukushima Nuclear Fall Out Still Nowhere Near Being Contained.

Unfortunately site safe again. a look inside the Fukushima plant suggests otherwise,” says What he saw was far from the BBC’s Rupert Wingfieldreassuring. Hayes in an extremely worrying report released recently on their “Inside the shattered building website. (building number 4), more than 1,500 spent fuel rods were http://www.bbc.co.uk/news/ still sitting inside a cooling world-asia-21737910 pool. They were still highly radioactive and the pool was After becoming only the outside the reactor’s steel and second foreign TV journalist concrete containment vessel, to be allowed to visit the site perched high on the third floor. since the disaster 2 years ago, Wingfield-Hayes, very bravely “A race is now on to get the fuel in our opinion, spent 5 hours rods out. A huge steel structure
is being erected around building four that will be used to raise the spent fuel out. But that operation will not start until the end of this year, and will then take two more years to complete. If another large earthquake strikes during that time there is real concern the building could collapse.” You sense from the report and the accompanying video that the clean up team are operating in completely unchartered territory and that there is no standard textbook approach to dealing with a nuclear accident of this magnitude. “Reactor number four was only the tip of a radioactive iceberg. Two hundred
meters away I could clearly see the twisted and rusting steel of reactor building number three. Two years after the disaster it was still virtually untouched. The reason was simple. The radiation at reactor three was so high workers could not safely go near it.” “Our bus rushed past without stopping. The Geiger counter reading was over 1,000 micro sieverts an hour. That is
roughly the same as ten chest X-rays every hour, or a full CT scan every ten hours.” SO WHAT? You have to wonder don’t you, exactly how many of these disasters we need to suffer before we finally conclude that their inherent dangers (particularly in an increasingly volatile world) completely outstrip their benefits. Let’s face it, with the
exception of journalists like Wingfield-Hayes, the world still refers to incidents such as Fukushima as ‘accidents’? As if someone’s just dropped a tray of eggs in their local supermarket. “Oh whoops, sorry, looks like I’ve just released a few tons of radioactive waste into the atmosphere. Still, no point crying over spilt milk. Does anyone know how to clear this stuff up?” ‘Cock-ups of near apocalyptic proportions’ would probably be more apt. It’s not as if Fukushima was an isolated incident. The list of near misses is actually worryingly high: Mayak (1957) Windscale (1957) Idaho (1961) Three Mile Island (1979) Chernobyl (1986) Severesk (1993) Tokaimura (1999) Mihama (2003)
Fukushima (2011) Macoule (2011). (Yes, we’ve had another one since Fukushima.) To use an agricultural analogy, we might have the technology to milk the power we need from nuclear power stations, but we really don’t have a clue how to clear up their fæces. Particularly when that fæces comes in the form of a wallspraying outburst of projectile diarrhea. Yet the UK government, for example, is still seemingly determined to
push ahead with plans for new nuclear power stations. (If they can only find somewhere in the country willing to play host.) Perhaps the only real plus from Fukushima is that it was the straw that finally persuaded countries like Japan and Germany to abandon their own nuclear programmes in favour of safe, clean renewable energy. If only the windy old United Kingdom would do the same.
ONE LAST SHOT UK Government Ready To Give Green Light To New Nuclear Power Station At Hinkley
The News: Planning permission would now be a formality if French firm EDF Energy decides to go ahead with its £14bn plan to build a new nuclear power plant at Hinkley Point, Somerset, in the south west of England. It would become the first nuclear power plant to be built in the UK since Sizewell B in 1988, reports the BBC.
electricity bills so EDF wants written guarantees that even if the cost of electricity were to fall in the future, it would still be allowed to charge consumers the higher price. SO WHAT? “Great, another high profit unsustainable short term fix with dangerous waste that no one knows what to do with, but **** it, let our grandchildren deal with it!” (Comment left on BBC website)
The plant would provide the UK with a 7% increase in capacity, enough to power 5 “I reckon the French million homes. are going to try to invade us. That’s why EDF has not yet they did their little committed to “practice” invasion on the project as its us, that’s why they representatives are still have come up with negotiating with UK cunning plans to get us government ministers, to “share” our military the amount it will be with theirs so we get allowed to charge for rid of ours, that’s why its output for the next they plan on improving few decades. our infrastructure. This is all so when they The project would be invade, everything is paid for out of future ready for them. I’m

More than half the firms that would work on Hinkley would be British. The UK would once again become a centre for nuclear build expertise. RollsRoyce, for example, is likely to be a partner in the building of the reactor. Future projects would come in cheaper and more efficiently delivered, expertise could be exported abroad.” (The Daily Telegraph’s Kamal Ahmed, forgetting for a moment that actually, we sold Rolls Royce to the Germans in 2002. But still, such passion.)
WEDGING THE GAP Renewables Now A Major Contributor To UK Energy, Reports The Renewable Energy Association (REA)

Renewable electricity up 20% on previous year. The News: 2012 was a strong year for the performance of renewable energy generation, mainly due to new renewable power projects coming on-stream, Government figures reveal . 11.3% of the UK’s electricity last year was generated from renewables overall, and 12.5% in the fourth quarter. Much of this growth is due to new on- and offshore wind farms, in spite of lower than average wind speeds over the year. 2012 was also fairly dry, meaning less output from hydro. Biomass generation increased 17%, largely thanks to Tilbury’s conversion to biomass, and the capacity of solar PV increased 70%, up to 1.7GW. Total UK renewable power capacity now stands at 15.5GW.
SO WHAT? “Renewables now generate more than 10% of our electricity on average. Compared to 2011, generation from onshore and offshore wind increased by 15% and 46% respectively, while solar PV capacity is up 70%. The conversion of Tilbury also shows what a big difference biomass can make, especially at a time when the Government is desperate to bring forward affordable, baseload, low carbon generation. “It is a critical time for industry as the Energy Bill makes its way through Parliament. We look forward to working with Michael Fallon in his new role as Energy Minister, particularly in light of his work on the 2008 Planning and Energy Act, but a change of Ministers at this crucial time further complicates matters.” (Gaynor Hartnell, Chief Executive, REA)

IT’S ALL ABOUT DANCING TO THE SAME TUNE ‘Developing The ‘Internet Of Things’ Could Deliver a 20% Saving In Greenhouse Emissions,’ Says New Report
The big story emerging from the ‘Mobile World Conference’ in Barcelona, is that the development of a new technology that allows machines to talk to each other (inevitably referred to as ‘M2M’ technology) could end up delivering an 18.6% reduction in global greenhouse emissions. The report, entitled ‘Machine-to-Machine Technologies: Unlocking the Potential of a $1 Trillion Industry’, was delivered by The Carbon War Room (a non-governmental organisation founded by Sir Richard Branson, which is far less sinister than it sounds) in conjunction with telecoms giant AT&T. “Machine to machine (M2M) communication – whereby sensors and networks allow all the parts of a physical system to communicate directly with each other – will radically change the way we work, live and travel. M2M will allow us to do more with less, but only if the industry can overcome current market barriers,” the report concludes.
seems to be suggesting is that if we can somehow link all our machines together and get them to routinely chat to each other (hence the attention-grabbing concept of an ‘Internet of Things’) and instill in them a certain degree of ‘intelligence’ as to the way they can most energy-efficiently interact, we should be able to save about a fifth on our current greenhouse emissions by 2020. The sort of savings we really do need to be coming up with soon if we’re going to succeed in restricting global warming to just a 2 degree rise. A restriction which will require us to get our total emissions down to 1990 levels by 2020. Oh, and generate cost savings and new revenue in the region of 10 to 15 trillion dollars over the next 2 decades. “Decoupling economic growth from GHG emissions is a global imperative requiring efforts by governments, businesses and individuals,” the report says.
In a nutshell, what the report “Preventing average global
temperature increases of more than 2°C will require our GHG emissions to shrink by at least five-seven gigatons (billion metric tons, or Gt) of carbon dioxide equivalent (CO2e) – a massive amount, equal to 10-15 per cent of the world’s total annual emissions today. Luckily, we now possess mature technologies that can accomplish this goal, and even surpass it.”

Western World Should Halve Its Consumption Of Meat, Say Scientists In Wake Of Horsemeat Scandal A United Nations Study has concluded that modern farming practices are destroying the natural world and that people in ‘developed’ continents such as North America and Europe should lead the way by halving their consumption of meat. The scientists say that the recent horsemeat scandal has highlighted our spiraling demand for meat in the last 50 years, which has resulted in the creation of a dangerous
black market in undocumented livestock (such as horses) and an ever-increasing drain on global food resources. Livestock farming diverts huge quantities of grain from human to animal consumption while also requiring vast amounts of environmentally damaging fertilisers, pesticides and herbicides. “The attention this meat scare has drawn [highlights] poor quality
meat. It shows society must think about livestock and food choices much more, for the environment and health,” said Professor Mark Sutton, the report’s lead scientist. The answer according to Sutton is more vegetables on our plates, and less meat. “Eat meat, but less often – make it special. Portion size is key. Many portions are too big, more than you want to eat. Think about a change of culture that says, ‘I like the taste, but
I don’t need so much of it. “Most people don’t notice,” he said, alluding to a recent UN event at which diners were offered a third of the ‘normal’ amount of meat and more vegetables to make up for it. 90% of them reported being just as satisfied with the meal. SO WHAT?

Hence efforts like ‘meat free Monday’ in the US, which isn’t winning many friends among the country’s farmers (and who can blame them?) but is doing a very good job at highlighting the true cost of meat production in terms of our total available resources these days.
