Here comes the sun

A giant nuclear fusion reactor could solve the world’s energy problems – but only if it doesn’t melt

For now, it is a hideous sight. In Cadarache, 60 kilometres north of Marseilles, workers have cleared over 40 hectares of wooded land and moved more than two million cubic metres of soil. However, this scar on the Provençal landscape has been earmarked for greatness. It is where a multinational team of scientists is attempting to build earth's second sun.

As projects go, the International Thermonuclear Experimental Reactor (Iter) could hardly be more ambitious. Its aim is to show that we can control nuclear fusion reactions. This is the same process as generates energy in stars and could, in theory, release up to four million times more power than burning fossil fuels. If Iter works, we'll have solved our energy problems.

But ifs do not come much bigger than that. We do not yet know if it is even possible to build the machine. "Fusion is a big bet - it's not a dead cert," says Steven Cowley, director of the Culham Centre for Fusion Energy, the hub of UK fusion research. The stake for that bet is set at €10bn (£9bn), but that figure is double the original estimate for the project and may rise further; Iter's council was recently presented with just the latest in a series of revised budgets and schedules. Whatever it eventually costs, we will not find out whether the gamble has paid off until 2026, the earliest date for the project's completion.

All this uncertainty and delayed gratification, not helped by the price tag, has generated heat of its own. Iter's critics, who include prominent scientists and Greenpeace International, have argued that the money would be better spent on pressing challenges such as finding ways to increase near-term energy production.

However, the fusion scientists are keen to point out that they are being responsible. It is no use surviving the near term only to find we are faced with a huge energy debt, they argue. World consumption is on course almost to double by 2030. Solar energy and nuclear fission might be more immediately available, but both have their limits. Nuclear fusion's main fuel is derived from seawater, and there are no long-term nuclear waste products. Nothing, they say, would fill the energy gap like this.

Bombard with microwaves

That is what Iter's members - Russia, the EU, Japan, China, South Korea, the US and India - are hoping their 23,000-tonne monster will prove. The jaw-dropping size of Iter is necessary because making commercially viable electricity from fusion depends on economies of scale. Previous successes in smaller reactors have managed to break even, producing as much energy as they consume. But the Cadarache reactor should, according to its designers, give out ten times more power than it takes in.

Operating at 150 million degrees Celsius, ten times hotter than the core of the sun, Iter is certainly going to take in a lot of power. Surprisingly, this kind of temperature is not too hard to achieve. The fuel for Iter is two heavy isotopes of hydrogen called deuterium and tritium. Bombard them with microwaves, magnetic fields and other particles, and they will get hot enough to fuse, releasing energy.

The hard bit comes with the maelstrom created inside the reactor. The high temperature creates a "plasma", a gas of charged particles. Plasma is an engineer's worst nightmare. For a start, it cannot be allowed to touch the reactor's walls; if it does, they will melt, and the whole thing will have to be rebuilt.

The plasma can be held away from the walls using immensely strong magnetic fields, but only - so far - for short periods. This is because the plasma tends to slip around in its magnetic cage, forming areas of high density that can burst through. Even if Iter engineers manage to hold it stable for ten minutes at a time, which is as much as they hope to achieve, the plasma will still shoot out neutrons that can destroy the walls.

This is the frontier where Iter succeeds or fails, Cowley believes. "We're pretty sure we can get out ten times the energy we put in," he says. "But if we have to replace the wall every year, that's going to be a very expensive way to produce electricity."

Once all the engineering problems are overcome, the plant will be able to produce only 500 megawatts of power, equivalent to a single coal-fired power station. Members will then have to build their own fusion reactors using the know-how gained at Iter. Payback will come, so the rationale goes, through these states' privileged position in the trillion-dollar, post-fossil-fuel, global energy market.

It's not an argument that worked for Canada, which pulled out of the fusion dream in 2003. The US also wavered, though it has now committed to paying 9 per cent of the cost. The EU is putting in the largest share, taking responsibility for just under half of the project. Thanks to the strange arithmetic of fusion, however, EU taxpayers may end up paying significantly more than half of the money.

Creative accounting

The funding of Iter is a notoriously slippery subject. Roughly 90 per cent of the contributions are due "in kind" - states will contract firms to manufacture equipment for a cost that they do not have to declare to the other states. Even more confusing is that each of Iter's components has been designated as worth a certain number of "Iter accounting units". Members can then choose which components they commission firms in their countries to design and build. This will affect the balance of expenditure; the cost of producing a particular magnet is likely to be far less in China than in Germany, for instance.

Then there is the complexity of the various components. The UK has chosen to build superconducting magnets and the main container vessel for the plasma. These, it turns out, will cost much more to design and build than initial estimates suggested. Cowley maintains this is a good thing: the money will go to UK in­dustries and provide them with engineering challenges that will have their own spin-off benefits, he says.

“We will never really know how much some countries spent," admits Neil Calder, Iter's spokesman. This lack of clarity about the cost may prove to be the project's Achilles heel.

In May, the journal Nature declared it "deeply unfair" to the taxpayers paying for the project and called for "an honest public debate". Science also weighed in, suggesting that fusion's problems could well be intractable. Fusion, said one commentator in the journal, is "the science of wishful thinking".

There is no sign of second thoughts from any of the members, however. According to Sébas­tien Balibar, a director at France's National Centre for Scientific Research, members stand to gain nothing by halting the project. "Now that Iter has been decided and is under construction, it would be better that it produces useful results," he says.

Brothers in blood: how Putin has helped Assad tear Syria apart

The Syrian catastrophe has created the worst humanitarian crisis since the end of the Second World War. And the world watches helplessly as Putin and Assad commit war crimes.

Sometimes we know the names. We know Omran Daqneesh, the five-year-old boy who, covered in mud and dust, was pictured on the back seat of an ambulance in the aftermath of an air attack. We know his name because pictures and a video of him were released on social media and travelled around the world. The outrage that followed was widespread and sincere, the image of the dazed little boy seeming to symbolise the greater plight of the beleaguered residents of Aleppo. But then the moment passed. Few will know that a few days later doctors announced that Omran’s elder brother Ali, who was injured in the same air strike, had died from his injuries. He was ten.

Sometimes we know the names of the babies pulled from the rubble of collapsed buildings – occasionally alive, but often dead; or the names of the children weeping over lost parents; or the women grieving over lost husbands and children; or the elderly simply waiting (and sometimes wanting) to die.

We know Bana Alabed, the seven-year-old girl trapped inside Aleppo whose Twitter account has gone viral in recent weeks. “Hi I’m Bana I’m 7 years old girl in Aleppo [sic],” reads the on-page description. “I & my mom want to tell about the bombing here. Thank you.”

A series of pictures depicts Alabed and her mother, Fatemah, struggling to live as normal a life as possible, one showing the little girl sitting at an MDF desk with a book. Behind her, in the corner, is a doll. “Good afternoon from #Aleppo,” says the caption in English. “I’m reading to forget the war.”

The conflict, however, is never far away. Alabed, whose mother taught her English, has repeatedly tweeted her own fears about dying, followed by stoic messages of defiance whenever the immediate threat of an impending air strike passes. On the morning of 3 October, her words were simply: “Hello world we are still alive.” On 17 October, Fatemah tweeted: “The airstrikes ended in the morning, all the last night was raining bombs.”

But in most cases we never know the names of the victims of air assaults led by Presidents Bashar al-Assad and Vladimir Putin. One of the most haunting images to emerge in recent weeks was that of a mother and child, killed while sleeping in the same bed. The scene had an eerily preserved-in-amber feel to it: a snapshot of snatched lives, frozen in the act of dying. Pictures of ruined buildings and distraught civilians have become routine now, holding our attention briefly – if at all.

As many as 500,000 people are believed to have been killed since the beginning of the Syrian uprising in early 2011. According to a report released in February this year by the Syrian Centre for Policy Research, a further 1.9 million have been wounded. Taken together, those figures alone account for 11.5 per cent of Syria’s pre-revolutionary population. Combine that with the number of Syrians who have been displaced – more than ten million (almost 50 per cent of the population) – and the sheer scale of the disaster becomes apparent.

The conflict has become the worst humanitarian crisis since the Second World War. Today it centres on Aleppo, in north-west Syria, one of the oldest continuously inhabited cities in the world, and a cradle of human civilisation. Various conquerors from the Mongols to the French have fought battles there but none, so it would seem, has been quite as ruthless or committed to the city’s annihilation as Bashar al-Assad.

Aleppo remains the most significant urban centre to have been captured by the anti-Assad rebels, most of whom will (by now) be strongly influenced by an Islamist world-view. Indeed, the most prominent fighting groups on the rebel side are overwhelmingly Islamist in their troop composition and beliefs, a sad marker of Western failures to support secular forces that led the anti-regime resistance in the incipient phases of the uprising.

Yet Aleppo remains too important to fail. Although rebel forces succeeded in capturing only half of the city – the western side remained firmly in the control of the regime – the symbolism of anti-Assad forces holding ground in Syria’s second city (which also served as the country’s economic hub) has buoyed the rebel movement.

Assad is more brazen and bullish than at any other point since eastern Aleppo fell into rebel hands in July 2012. That optimism is born of a strategy that has already worked in other parts of the country where the regime’s troops have slowly encircled rebel-held areas and then sealed them off. Nothing can leave, and nothing can enter. Once the ground forces seal off an area, an aerial campaign of barrel bombs and missile attacks from both Syrian and Russian fighter jets inevitably follows.

To get a sense of just how terrible the aerial campaign has been, consider that the United States accused the Russian air force of potential war crimes when a UN aid convoy was bombed just west of Aleppo last month. It was carrying food and medicines when it was hit. Since then, the UK and France have said that Russia’s bombardment of Aleppo amounts to a war crime.

Putin’s support has come as a boon to Assad ever since Russia formally entered the conflict in September 2015. Despite his administration already using Iranian forces and aligned groups such as the Lebanese Shia militia Hezbollah, rebels had continued to make significant gains throughout the early months of 2015. The most important of these was the capture of Idlib city, 40 miles from Aleppo, which presented Assad with two problems. The first was that it dented the official narrative of revanchist military successes by his forces. The ­second was that it handed the rebels power in a province adjoining Latakia Governorate in the west, where Syria’s Alawites are largely concentrated (Russia has an airbase in an area south-east of the city of Latakia). The Alawites are a heterodox Shia sect to which the Assad family belongs, and which forms the core of their support base.

Keen to reverse these gains – and others made elsewhere – Assad enlisted Putin, given Russia’s long-standing interests in, and ties to, Syria. The Kremlin has long regarded Syria as an important ally, and has served as the country’s main arms supplier for the past decade. There are important assets to preserve, too, such as the Russian naval base in the port city of Tartus on the Mediterranean, which was first established during the Soviet era.

For his part, Putin has felt emboldened by events. The world is changing – not just in the Middle East and North Africa, where the
contours of power continue to be recast, but also closer to home in Ukraine, where the pro-Russian president Viktor Yanukovych was overthrown in 2014.

The West is still haunted by the 2003 invasion of Iraq and has been reluctant to be drawn too deeply into the Syrian War. In 2013, the Assad regime used chemical weapons against its own people. This was a violation of President Barack Obama’s so-called red line against the use of chemical weapons, but no retaliatory action came and there was nothing to prevent the Kremlin from using force to shape events in Syria – as it had done in Ukraine.

All of this has marked a new phase of brutality in a conflict already noted for its barbarism. Civilians who avoid death from combined Russo-Syrian air assaults suffer under Assad’s strategy of “starve or submit”, in which supplies are withheld from besieged areas, slowly choking off those ­inside. It has been used to devastating effect against civilians in towns such as Madaya and in Daraya, on the outskirts of Damascus, both of which fell to government control after being sealed off from the outside world for several years. Such a strategy is not designed to deliver quick victories, however. Consider how the residents of Daraya defied Assad’s forces for four years before capitulating in August 2016.

Assad and his allies (Putin, Iran, Hezbollah) have decided to punish and brutalise, deliberately, civilian populations in rebel-held areas. To invert the famous aphorism attributed to Chairman Mao, they hope to dredge the sea in which the revolutionaries swim. And so, it is the 300,000 residents of eastern Aleppo who must suffer now.




It’s easy to lose track of precisely what is happening in the Syrian War as parcels of land swap hands between rebels and the regime. Assad’s forces first began encircling Aleppo at the start of July this year and succeeded in imposing a siege by the middle of that month, after cutting off the last of two rebel-controlled supply routes into the city. The first was the Castello Road, which leads from the town of Handarat into the north-western part of ­rebel-controlled territory. The second route, via the Ramouseh district (which led into the south-western end of the city), had already been sealed off.

The closure lasted for roughly four to five weeks before the rebels re-established access. Aleppo is too important for them, and the siege has forced various groups to work together in breaking it. The effort was led by Jaish al-Fateh (JaF, the “Army of Conquest”), an umbrella group and command structure for several of the most prominent jihadist and Islamist groups operating in northern Syria. JaF also co-ordinated the Idlib military campaigns. One of its key members is Jabhat Fateh al-Sham (JFS, “the Syrian Conquest Front”), which was previously known as Jabhat al-Nusra (JaN or “the Supporters’ Front”) and was recognised as al-Qaeda’s official chapter in Syria.

Several months before the regime began its assault on Aleppo, rebel groups in the north recognised the deteriorating situation there, stemming principally from Russian air strikes. As a result, al-Qaeda urged the various factions to merge and work together to counteract not just Assad, but also Putin. Even the global leader of al-Qaeda, Ayman al-Zawahiri, issued a speech last May titled “Go Forth to Syria”, in which he called on all fighting groups to unite in order to consolidate their control across the north. This opened the way at the end of July for Jabhat al-Nusra to declare that it was formally severing its links with al-Qaeda. It “rebranded” as Jabhat Fateh al-Sham.

There are two reasons for doing this. The first is to erode partisanship among the Islamist groups, forcing them to set aside differences and narrow their ambitions in favour of the greater goal – in this case, the breaking of the siege of Aleppo, while also deepening rebel control across the north. The second aim of rebranding is to win popular support by portraying themselves as fighting in the service of ordinary civilians.

Groups such as JFS and others are succeeding in both of these goals. Responding to the abandoned and assaulted residents of Aleppo, they have repeatedly demonstrated their commitment to alleviating the humanitarian crisis. Much of their messaging echoes this theme. The group’s English-language spokesman is Mostafa Mahamed, an Egyptian who previously lived in Australia. “[JFS] is deeply embedded in society, made up from the average Syrian people,” he explained on Twitter, after the group decoupled from al-Qaeda. “We will gladly lay down our lives before being forced into a situation that does not serve the people we are fighting for . . . jihad today is bigger than us, bigger than our differences.”

It is indisputable that this ethos of “fighting for the people” has endeared the group to civilians living in besieged areas – even when those civilians don’t necessarily agree with the full spectrum of its religious beliefs or political positions. That goodwill was only reinforced when the group helped break the siege of Aleppo (in which approximately 500 rebels were killed) in August, if only for a few days. Assad reasserted control within a week, and entrapped the residents again in the middle of that month. The rebels are now planning how to break the siege decisively, but have not yet launched a major counteroffensive.




A freelance American journalist and film-maker, Bilal Abdul Kareem, who has reported on rebel movements inside Syria more intimately than most, has found himself among those trapped inside eastern Aleppo since the siege was restored seven weeks ago. “We came here expecting a two- or three-day trip,” he told me during an interview over Skype.

Life inside is becoming insufferable for civilians, Abdul Kareem said; every building is potted and scarred by shrapnel damage. Those whose homes remain standing are the lucky ones. “Your day consists of nothing,” he said. “There’s no work, there’s no fuel, no industrial zone, no food to sell. ­People sit around and chit-chat, drink tea, and that’s all they do.”

Food supplies are already running low, with most people limiting themselves to basics of chickpeas and groats – crushed grains such as oats or wheat. Sealed off from the rest of the world, those inside preoccupy themselves with survival and wait for the next wave of attacks.

It is tempting to ask why the inhabitants of Aleppo did not flee when they had the chance. Indeed, the Assad regime routinely accuses the rebels of preventing civilians from leaving besieged areas, though there is no evidence to support this view. On 17 October Russia and the Syrian regime said they would halt their bombardment for eight hours on 20 October to allow rebels and civilians to evacuate the city.

In truth, what choice do the civilians have? Most do not trust Assad and they are therefore unwilling to move into regime-administered areas. The alternative is to become refugees, with all the uncertainties and trials associated with that. For instance, refugees have found themselves subject to sectarian violence in Lebanon, and they have few opportunities to find employment in Lebanon, Turkey or Jordan, the three countries where most of the fleeing Syrians have found shelter.

For them, merely to exist in rebel territory is an act of defiance, which is precisely why Assad’s forces make no effort to distinguish between combatants and civilians in rebel areas. To be present is a crime.

The effects of this have been devastating. A spokesman for the Syrian American Medical Society told Middle East Eye, an online news portal, that in July, Syrian and Russian jets had hit medical facilities in rebel-held territory every 17 hours.

Only a few hospitals and medical staff remain. The physical conditions are primitive and perilous. Doctors work in makeshift facilities – a former flat, a commercial garage – which makes them unable to provide anything beyond basic emergency care. In-patient facilities are non-existent, not just because of high demand from those newly injured in fresh attacks, but also from fear that the facility itself will be targeted. “People are literally shuffled out of the hospital with IV [intravenous drips] in their arms,” Abdul Kareem says.

The West’s indifference to all this – coupled with its occasional pious pronouncements and diplomatic dithering – has squandered any goodwill Washington might once have had among Syria’s beleaguered civilians. When Sergey Lavrov, Russia’s foreign minister, and John Kerry, the US secretary of state, agreed a ceasefire in September it lasted barely two days because they overlooked the fears of those trapped inside eastern Aleppo.

The deal had stated that no party would try to capture any new territory. That might seem reasonable enough but given that the ceasefire came into effect just days after Assad re-established the siege of Aleppo, those on the inside were being asked, in effect, to acquiesce to their own starvation.

Deprived of food and medication, no one trusted Assad to negotiate access in good faith, especially after he thwarted UN efforts to deliver aid. “People saw it as a conspiracy,” Abdul Kareem told me. Moreover, there were no significant groups inside eastern Aleppo that claimed to have accepted the terms of the ceasefire in the first place. Kerry had negotiated on their behalf without approval and without securing any humanitarian concessions.

“What planet are these people on?” Abdul Kareem asked. “[Do] they think people will turn on their protectors, for people who didn’t do them any good? They look to JFS and Ahrar [Ahrar al-Sham is one of the Islamist groups fighting in JAF]. Western intervention is pie in the sky.”

The rise of these reactionary rebels is a direct result of liberal elements not being strongly supported at any stage in the conflict. Left to fend for themselves, many have deserted their cause. Those who have persisted not only risk the constant threat of being killed by Russo-Syrian bombs, but are also at threat from jihadist elements operating in rebel areas. That much was clear when remnants of the secular opposition protested against the leader of JFS, Abu Mohammed al-Golani, in the southern Idlib town of Maarat al-Nouman earlier this year. Many of those who did were arrested by jihadists and intimidated into silence.

Whereas liberals are fragmented and frayed, the Islamist rebels continue to coalesce into an ever more coherent unit. The overwhelming might of Russian airpower has convinced them of the need to form a united front in order to pool their resources and co-ordinate their efforts. That is one of the reasons why a jihadist group called Jund al-Aqsa (“Soldiers of al-Aqsa”) announced early this month that it was disbanding and being absorbed into JFS.

Herein lies the real story of how Aleppo – and, indeed, Syria itself – has been delivered to the jihadists. A conspiracy of all the external parties has forged a menacing millenarian movement that is embedded in civil society and communities across the north. Whether Aleppo falls or not, the jihadists will endure.
