US scientists have carried out the first ever nuclear fusion experiment to achieve a net energy gain, paving the way for a “clean energy source that could revolutionise the world”.

During a landmark news briefing at the Lawrence Livermore National Laboratory in California, officials revealed the successful fusion experiment had taken place last week.

As it happened: ‘Amazing’ scientific breakthrough could create limitless energy

It was the result of “60 years of global research, development, engineering, and experimentation”, which could eventually become the backbone of commercial electricity generation.

Such a result would supercharge the world’s shift to renewable energy, helping to fight climate change.

US energy secretary Jennifer Granholm said the breakthrough “will go down in the history books”.

“This is one of the most impressive scientific feats of the 21st century,” she added.

How was the experiment carried out?

The experiment involved 192 high-powered laser beams being fired at a capsule containing the elements deuterium and tritium, heating it to a temperature of more than three million degrees centigrade – thus briefly simulating the conditions of a star.

Dr Marvin Adams said it had been carried out “hundreds of times before”, but had never successfully produced more energy than was consumed.

“For the first time, they designed this experiment so that the fusion fuel stayed hot enough, dense enough, and round enough for long enough that it ignited, and it produced more energy than the lasers had deposited,” he said.

“About two mega joules in, about three mega joules out – a gain of 1.5, the energy production took less time than it takes light to travel one inch.”

It was, as he quipped, “kind of fast”.

While the target was smaller than a pea, the lasers – part of the so-called NIF system – are powerful enough to deliver more energy than the whole power grid sustaining all of the US.

Chief engineer Jean-Michel Di Nicola said it was “the size of three football fields and delivers energy in excess of two million joules with a peak power of 500 trillion watts”.

“For a very short amount of time, a few billionths of a second, it exceeds the entire US power grid,” he said.

How long before the process can create useable energy?

The question on everyone’s lips following the news briefing was how long it would take before the process can be utilised for creating energy that we can actually use.

Dr Kim Budil, director of the Lawrence Livermore National Laboratory, admitted it would take “probably decades”.

President Joe Biden has said he hopes a commercial fusion reactor will be in place within 10 years, and officials acknowledged that the private sector would have to play a big role in accelerating the shift from lab experiments to commercial electricity production.

Other nuclear fusion projects will also have a role to play – and the scientists in California cited the work of a team in Oxfordshire, who earlier this year used their JET machine to generate around 11 megawatts of energy.

That was far more than was generated in the NIF experiment, but – crucially – did not achieve net energy gain.

A significant scientific milestone – but lasers require huge power

As Dr Marv Adams was holding up the cylindrical target containing the “peppercorn-sized” pellet of fusion fuel, he confirmed they had achieved “ignition” of a fusion reaction.

He also revealed the scientists put about 2MJ of energy into their fusion reaction and got about 3MJ out.

That’s the evidence of the “energy gain” that this announcement is all about.

That’s the significant scientific milestone: proving a fusion reaction itself can generate more energy than you put into in.

But they had to use 300MJ of electricity to power up their lasers.

So from an energy production point of view, they’re still having to put in 99% more power into the machine as a whole as they are getting out.

University of Oxford Professor Gianluca Gregori, a specialist in the kind of lasers used at the lab, stressed that the amount of energy produced was smaller than that needed to power a wall plug.

“While this is not yet an economically viable power plant, the path for the future is much clearer,” he added.

Jeremy Chittenden, professor of plasma physics at Imperial College London, said scientists “will need to find a way to reproduce the same effect much more frequently and much more cheaply”.

If they do, it would be a huge shot in the arm for the world’s push towards renewables.

At least 114 dead after Philippines typhoon, as state of emergency declared and more than 100 still missing

At least 114 dead after Philippines typhoon, as state of emergency declared and more than 100 still missing

The Philippines has declared a state of emergency after a typhoon left at least 114 dead and 127 missing.

Philippine President Ferdinand Marcos Jr issued the “state of national calamity” declaration after a meeting with disaster officials on Thursday.

It comes after Typhoon Kalmaegi made landfall on Tuesday, striking the country’s central provinces. It is the deadliest natural disaster to hit the Philippines this year.

After reaching the country, the storm hit with sustained winds of 87mph and gusts of up to 121mph.

Authorities in Vietnam, meanwhile, are bracing for Kalmaegi’s approach. Forecasters warned that Ho Chi Minh City faces a heightened risk of severe flooding, as high tides would coincide with the expected heavy rainfall from the typhoon.

So far, the deaths recorded were mainly as a result of flooding in flash floods. The country’s civil defence office said that at least 71 people died in Cebu.

Cebu, a province of more than 2.4 million people, was still recovering from a 6.9 magnitude earthquake on 30 September, which left at least 79 people dead.

A state of calamity was previously declared there to allow authorities to disburse emergency funds more rapidly.

The province’s governor Pamela Baricuatro told the Associated Press on Thursday: “We did everything we can for the typhoon but, you know, there are really some unexpected things like flash floods.”

Almost two million people were affected by the tropical cyclone, with more than 560,000 displaced and almost 450,000 evacuated to emergency shelters.

The crew was on its way to provide humanitarian aid to provinces affected, the military said, without giving the cause of the crash.

The Philippines is one of the world’s most disaster-prone countries.

It is affected by around 20 typhoons and storms each year, is also often hit by earthquakes, and has more than a dozen active volcanoes.

Elon Musk: Why some are starting to question if the world’s richest man is still value for money

Elon Musk: Why some are starting to question if the world's richest man is still value for money

Elon Musk is already the world’s richest man, but today he could take a giant step towards becoming the world’s first trillionaire.

Shareholders at Tesla are voting on a pay deal for their chief executive that is unlike anything corporate America has ever seen.

The package would grant Musk, who already has a net worth of more than $400bn, around 425 million shares in the company.

That would net him about $1trn (£760bn) and, perhaps more importantly to Musk, it would tighten his grip on the company by raising his stake from 15% to almost 30%.

The board, which has been making its case to retail investors with a series of videos and digital ads, has a simple message: Tesla is at a turning point.

Yes, it wants to sell millions of cars, but it also wants to be a pioneer in robotaxis, AI-driven humanoid robots, and autonomous driving software. At this moment, it needs its visionary leader motivated and fully on board.

Musk has served his warning shot. Late last month, he wrote on X: “Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla? It won’t be me.”

Not everyone is buying it, however.

With so much of his personal wealth tied up in Tesla, would Musk really walk away?

Bad for the brand?

Others see his continued presence and rising influence as a risk. Norway’s sovereign wealth fund, the world’s largest, which owns 1.1% of the company (making it a top 10 shareholder), has already declared it will vote against the deal. It cited concerns about “the award’s size, dilution, and lack of mitigation of key person risk”.

Several major US pension funds have followed suit. In an open letter published last month, they warned: “The board’s relentless pursuit of keeping its chief executive has damaged Tesla’s reputation.”

They also criticised the board for allowing Musk to pursue other ventures. They said he was overcommitted and distracted as a result. Signatories of that letter included the state treasurers of Nevada, New Mexico, Connecticut, Massachusetts, Colorado, and the comptrollers of Maryland and New York City.

All of them Democrats. Republicans have been more favourable. There is a political slant to this.

The signatories’ concerns with his “other ventures” no doubt include the time Musk spent dabbling in right-wing politics with the Republican inner circle. That made him a polarising figure and, to an extent, Tesla too.

Pay packet dwarfs rivals

Combine this with a mixed sales performance and a volatile share price, and some are wondering whether the carmaker has lost its way under his leadership.

Irrespective of performance, for some, the existence of billionaires – let alone trillionaires – can never be justified. Some may also ask why Musk is worth so much more than the leaders of Apple, Facebook, and Microsoft, or Nvidia, the world’s most valuable company by market capitalisation.

Nvidia‘s chief executive, Jensen Huang, received $49.9m (£37.9m) this fiscal year. So, how has Tesla come up with these numbers? Why is Musk’s pay so out of kilter with the benchmark? Does the company have a corporate governance problem?

The courts have suggested it might. Last year, a Delaware court took the view that Tesla’s board members, which include Musk’s brother Kimbal, were not fully independent when agreeing to a $56bn (£42.6bn) pay packet back in 2017.

The Delaware Supreme Court is now reviewing the case. It is a reminder that even if Musk meets his targets, a similar fate could befall the current package.

The Tesla board is holding firm, however. Robyn Denholm, the company’s chair, told The New York Times: “He doesn’t get any compensation if he doesn’t deliver,” adding that Musk “does things that further humankind”.

Tesla’s valuation is tied up in its promise to deliver revolutionary AI and robotics products that will change the world. Those ambitions, which include robots that can look after children, are lofty. Some would call them unrealistic, but the board is adamant that if they are to become a reality, only Musk can make it happen.

Under the deal, Musk would receive no salary or cash bonus. Instead, he would collect shares as Tesla’s value grows. To unlock the full package, he would have to increase the current market valuation six times to $8.5trn (£6.47trn). For context, that’s almost twice that of Nvidia.

There are other hurdles. The company would have to sell 20 million additional electric vehicles, achieve 10 million subscriptions to its self-driving software on average over three months, deploy one million robotaxis on average over the same period, sell one million AI-powered robots, and boost adjusted earnings 24-fold to $400bn (£304bn).

They are ambitious targets, but Musk has defied the sceptics before.

Driver hits several people on French holiday island of Ile d'Oleron

A driver has knocked down several people on the French island of Ile d’Oleron.

Two people are in intensive care following the incident and a man has been arrested, French interior minister Laurent Nunez said.

Several others were injured after the motorist struck pedestrians and cyclists, he added.

Thibault Brechkoff, the mayor of Dolus-d’Oleron, told BFMTV the suspect shouted “Allahu Akbar” (Arabic for God is Greatest) when he was detained.

Arnaud Laraize, the public prosecutor in La Rochelle, told the Sud Ouest newspaper the 35-year-old suspect “resisted arrest” and was “subdued using a stun gun”.

He said the suspect was known for minor offences such as theft, adding he was not on a list of people considered a threat to national security.

Pedestrians and cyclists were hit on a road between Dolus d’Oleron and Saint-Pierre d’Oleron, he added.
