Deepfake technology and the rewriting of history

SOCIETY

THE PRACTICE of doctoring photographs can be a very wicked thing, as we shall see. But it can also be trivial. Many of us must wish that various pictures of us did not exist. That awful school photo from primary school, or other disastrous snaps from our early childhood.

Is it wicked for us to do what we can to keep other people from seeing them? The fashion desert of the 1970s, for instance, where countless couples were married, do not display their wedding photographs. And who can blame them?

And to the Royal Family. Many of us still have no idea what the Princess of Wales was up to in her recent family snapshot, and outrage should be far from our minds.

The public demands a lot of photographs of the Royal Family, and why not? Half its power comes from the fact that it is a family, rather than a gang, cabinet, or a board of directors.

But families, even Royal ones, are not always as cheerful, contented, or well behaved, as we wish they were. It would have been a cleverer thing not to have done whatever it was that they did.

Far worse, and much fishier, was the curious case of the Bullingdon Club images of David Cameron, Al “Boris” Johnson, and George Osborne, from their Oxford days.

David Cameron obviously detested these records of debauchery, not wanting the public to be reminded of his time in this alcohol-fuelled society of well-heeled brutes. Was it a mere coincidence that they were mysteriously withdrawn by the company which owned them in 2008, so newspapers had to stop using them?

As it happens, Coincidence Theory (the idea that things happen by accident far more often than by design) is often believable. But not in this instance.

Odd was the obviously doctored 1992 Bullingdon pictures, featuring, among others, George Osborne and his (now former) friend Nat Rothschild. At first glance, it appears normal, but look carefully, and you will see it is full of suspicious peculiarities.

To the left of the middle, there’s a mysterious gap where somebody ought to be standing but isn’t. Weirder still, there’s a patch of shirt-front and waistcoat there, with no person attached. The right trouser leg of Mr Rothschild has a white lapel on it, not usual even under the bizarre dress code of the Bullingdon.

On close examination, the three seated figures at the front appear to have been stuck in place after being moved from somewhere else.

But again, these are tiny things compared with the monstrous crimes which the truly powerful commit with photographs, when they can. In pre-internet days, they simply hacked up the old pictures and replaced them with new items. Only the tiny few with access to original archives could ever be sure that what they were seeing was true.

THOUSANDS of images of the Russian revolutionary Leon Trotsky, sometimes standing near the Soviet demi-god, Vladimir Lenin, were wiped from Soviet history books, magazines, newspapers, and encyclopaedias, after Trotsky fell from favour.

In 1997, David King chronicled the photographic murder of the past, in his book “The Commissar Vanishes”. And it was murder. Those whose pictures were removed usually became dead soon afterwards.

The most poignant story of this kind is told by Milan Kundera in his Book of Laughter and Forgetting. It concerns the Czech Communist Vladimir Clementis. Clementis was standing beside the Czech Communist leader, Klement Gottwald, at a huge public meeting in Prague to mark their takeover of the country. It was snowing heavily, so Clementis lent his fur hat to the bare-headed Gottwald. Pictures recorded the comradely scene.

But four years later Clementis was purged for having the wrong view of Marx. He was hanged, cremated, and abused still further after death on the streets of Prague in a most barbaric way. And he was wiped from the images of 1948, leaving only his hat behind.

WHO knows what a future totalitarian regime might do, with the limitless powers provided by modern technology? This cannot only erase the past but can, through deepfake methods, create a wholly different past so convincing that only those who were actually there would be sure it was not a lie.

If human gullibility is anything to go by, even eyewitnesses of the truth might eventually fall in with the new altered version.

This was prefigured, as are so many evils of today, in George Orwell’s Nineteen Eighty-Four. The central character, Winston Smith, has the highly responsible job of cleaning up the paper archives of The Times, to make sure they do not clash with official lies. His discovery of a photograph, of three leaders of the ruling party – Jones, Aaronson, and Rutherford – fills him with terror. Its obvious location and stated date show that official history is false.

He sends it swirling into the “memory hole” which leads to the great furnace where all inconvenient facts are burned to ashes.

But he is still not safe. What if someone else saw him as he looked at it? What if the surveillance cameras picked it up (as we learn later, they did)?

The mere fact that he has seen this picture puts him in danger. He knows what nobody should know. He can never forget it. He cannot unsee it. His actual existence is a peril to his totalitarian chiefs.

Orwell writes: “It was curious that the fact of having held it in his fingers seemed to him to make a difference even now, when the photograph itself, as well as the event it recorded, was only memory. Was the Party’s hold upon the past less strong, he wondered, because a piece of evidence which existed no longer had once existed?”

As it turns out, in the torture cellars of the Ministry of Love, Winston, amongst other humiliations of the mind, is compelled to affirm that the photograph never existed.

In the end, with tears in his eyes, he joins the great deceived multitudes who believe what the authorities tell them and who have no idea what the past was really like, even if – especially if – they lived through it.

It is that sort of thing, not a mildly doctored family snapshot trying to provide some cheer and happiness, that we need to be worrying about. Useful as it is to know that the technology exists to turn anyone with the right equipment into a potential liar and fraud, and to make us all open to monstrous deceit, of a kind that even Stalin never dreamed of.

The truth needs to be told.

Ammonia is being developed as a low-carbon fuel

ENVIRONMENT

Intro: A start-up in America is developing world’s first ammonia-powered ships

THE Brooklyn Navy Yard’s sprawling industrial complex once employed 70,000 workers to build US battleships and aircraft carriers during the second world war. Almost 80 years later, it has become home to a New York city firm with a very different maritime mission – harnessing ammonia as a low-carbon fuel for the global shipping industry.

The start-up Amogy has already shown how ammonia-powered technology can work in a flying drone, a John Deere tractor and most recently a truck. Now, it is working on an ammonia-powered ship.

Most ships currently run on fossil fuels that emit greenhouse gases, accounting for 3 per cent of the world’s carbon emissions. One alternative involves converting vehicles to hydrogen power that would only emit water. But hydrogen gas needs to be compressed and liquified at -253°C for storage and transportation.

Ammonia could serve as an alternative hydrogen-bearing fuel that is more easily stored and transported in a stable liquid form at room temperature.

Hydrogen can be extracted by heating ammonia to high temperatures, which is a process that comes with its own energy cost. This is where Amogy’s technology comes in. To make ammonia power more viable, the company has developed what it describes as a more efficient and miniaturised “ammonia cracking” method that can chemically extract hydrogen from ammonia at a lower temperature. It uses a proprietary catalyst to speed up the process inside a chemical reactor that feeds into a hydrogen fuel cell.

A leading chemist at Saint Mary’s College of California says that what Amogy was able to bring to the table is that by having better catalytic technologies (all proprietary) they were able to miniaturise their ammonia cracking units and put them on board vehicles.

It was in July 2021 when Amogy first showed that its system could supply 5 kilowatts of power to a drone. By comparison, a standard ammonia cracking system for extracting that amount of hydrogen power is usually the size of a large shipping container. It also paved the way for a 100-kilowatt tractor demonstration in May 2022. That was followed by a 300-kilowatt truck demonstration in January 2023. The firm is now working towards demonstrating a 1-megawatt system in a tugboat.

Many countries already have pipelines and port facilities for handling ammonia that is produced industrially as fertiliser for agriculture. The US alone has more than 5000 kilometres of ammonia pipelines compared with 2500 kilometres of pipeline for transporting hydrogen – though it will need more to support ammonia-powered vehicles.

Another challenge is that ammonia still “has a carbon footprint associated with the production” because the standard industrial process uses natural gas. Low-carbon ammonia production would require use of carbon capture.

Cleaner alternative methods could ideally use electricity from renewable power sources to split water into hydrogen for conversion to ammonia.

Menacing spies in the sky

NATIONAL SECURITY

ABOVE our heads – some 80,000 feet up – a high-tech tussle is under way, with our most closely guarded secrets and our national security at stake. The shooting down of a number of intelligence balloons in recent days seems closer to a fictional tale rather than the serious threat they pose.

Four mysterious aircraft have been shot down in just nine days over North America, three by the US Air Force and one by the Royal Canadian Air Force.

The fictional perspective was primed when an American general sparked a storm of speculation when he said that he was not excluding extra-terrestrial origin for these intruders. General Glen VanHerck, commander of North American Aerospace Defence Command, when asked about the possibility of aliens, said: “I haven’t ruled out anything at this point.”

For these are – quite literally – unidentified flying objects. The language used to describe them recalls the unexplained sightings that, for decades, have puzzled even seasoned observers. UFO enthusiasts are enthralled. In 2021, the Pentagon set up the Airborne Object Identification and Management Synchronisation Group to investigate more than 100 incidents.

One of the aircraft, downed last week over Alaska, was described as “cylindrical and silverish gray”, about the “size of a small car” and with “no identifiable propulsion system”. Another, brought to earth on the US-Canadian border, was a “small, cylindrical object”.

Such intruders may also have crossed British territory. Rishi Sunak, newly enthused by military matters, says we can and will shoot them down if necessary.

Defence Secretary Ben Wallace has ordered a review. For now, the questions are multiplying. Are they Chinese? The West seems to think so. The regime in Beijing has protested about the downing of two of them – just peaceful weather balloons, it insists.

Security officials in the West say that China’s stratospheric surveillance programme has operated for many years, and over five continents. It is the brainchild of the Strategic Support Force, a secretive component of the People’s Liberation Army. So, why now? Why have we not noticed this before?

The short and probable answer is that we weren’t looking. These balloons and drones move incredibly slowly at great heights. Our air-defence radar works at lower altitudes. Our missile defence-systems track fast-moving rockets. US officials are now scouring data collected in previous years for signs of intrusions that they may have missed. So far, the Pentagon says, four previous instances have been identified.

In any case, malevolent intruders can easily be missed amid the thousand of innocent weather balloons launched every day. Gathering meteorological data provides perfect cover for covert missions. China counteracts claiming that the US has repeatedly sent spy balloons into Chinese airspace. The Americans deny this.

THREATENING

THE question looms as to why China would invest so much in these missions when it has more than 260 spy satellites? Being only 15 miles above the earth’s surface – satellites are seven times higher – gives them a clear edge in taking photographs and hoovering up electronic information, such as the ultra-sensitive “friend-or-foe” systems that prevent us shooting down our own warplanes.

These satellites can loiter over sensitive military installations, such as the RAF base at Boscombe Down in Wiltshire, used by American spy planes. Gathering information about the temperature and density of the air at high altitudes could also give a crucial advantage to missile-guidance systems. These spycraft may also be sent to test national defences.

Most worryingly, China published in 2018 a video showing a balloon being used as a platform to launch hypersonic weapons. These can travel vast distances at high speed, evading our defences and delivering either nuclear warheads, or electromagnetic pulse blasts that devastate all electrical and electronic devices.

What keeps these machines aloft and on course, thousands of miles from home, nothing is said.

Some clues, however, may come from here in Britain. We have Stratospheric Platforms, a company that offers internet access from a drone that can stay in the atmosphere for a week at a time, powered by a hydrogen engine. Another British start-up, Avealto, has a solar-powered craft in orbit that targets the same market.

Speculation abounds about even more advanced technologies. Aviation experts are eagerly awaiting news from the wreckage of the recent devices shot down.

Could, for example, the Chinese have cracked the difficulties of “ion propulsion”, which uses blasts of electrically charged air to stay aloft, and requires no combustion or moving parts like propellers or jets?

Prototypes of aircraft using this technology already fly, but they use too much electricity to be viable. Or so we think.

Whatever the case, the wreckage recovered from the recent incidents’ will be eagerly inspected by American military technologists hoping to gain an edge in the battle against spy wars in the sky. The results of their investigations will be classified secret. Why give clues to the enemy?

One thing in this extraordinary story is clear. These balloons are far from innocent and have caught the guardians of our security napping. Vigilance has been poor.
