The Perpetual Motion Believers

Why brilliant minds kept building machines that couldn't exist — and what they were really searching for

The Old Man with the Crust of Bread

In 1813, the mechanical engineer Robert Fulton—already famous for building the first commercially successful steamboat—paid a visit to Charles Redheffer's perpetual motion machine in Philadelphia. Redheffer had been charging men five dollars a head to witness the miracle: a gravity-driven engine that simply would not stop. But Fulton listened instead of looking. He heard a wobble, a jerk, an irregularity in the rhythm—the telltale stutter of a human hand. He noticed that the gears were worn on the wrong side, as if power were flowing into the machine rather than out of it. So Fulton knocked down some boards on a nearby wall and found a hidden catgut cord running through the ceiling. He followed it upstairs to a locked room. Inside sat an old man in a chair, eating a crust of bread with one hand and turning a crank with the other.ⁱ

I keep thinking about that old man. Not Redheffer the huckster, not Fulton the detective, but the anonymous laborer in the locked room—the actual motor. He is the secret truth at the heart of every perpetual motion machine ever built: somewhere, hidden from view, something is doing the work. The question that has fascinated me isn't whether perpetual motion is possible (it isn't) but why the dream of it has persisted for nearly a thousand years, consuming brilliant minds, vast fortunes, and entire lifetimes. What were they really cranking toward?

The Overbalanced Wheel and the Music of the Spheres

The first documented perpetual motion design comes from Bhāskara II, an Indian mathematician writing around 1150 CE. He envisioned a wheel with curved, hollow spokes partially filled with mercury. As the wheel turned, the mercury would flow to the ends of the spokes on one side, making it perpetually heavier, perpetually falling, perpetually spinning. It was elegant, intuitive, and wrong.ⁱⁱ The mercury does shift, but the shifting creates a shorter lever arm on the heavy side that precisely cancels the weight advantage. Nature, it turns out, is better at accounting than we are.

But Bhāskara wasn't stupid. He was one of the most sophisticated mathematicians of the medieval world, a man who made advances in calculus centuries before Newton. His error wasn't a failure of intelligence; it was a failure of paradigm. He didn't have the concept of energy conservation. No one did. And in the absence of that concept, the overbalanced wheel looked not just plausible but obvious. The mercury is heavier on one side. Of course it keeps turning. Sometimes the thing that makes an idea irresistible is simply the absence of the vocabulary to describe why it's wrong.

The early European perpetual motion builders operated under a paradigm even more seductive than Bhāskara's intuitive mechanics: theology. For Paracelsian thinkers like Robert Fludd—the English physician who in 1618 proposed a closed-cycle water mill where an Archimedes screw would pump water back up to the very tank that powered it—building a perpetual motion machine was essentially an act of prayer.ⁱⁱⁱ The logic ran like this: humanity (the microcosm) mirrors the universe (the macrocosm). God created the heavens to move in perpetual celestial motion—the planets never stopping, the stars never burning out. Therefore, building a machine of perpetual motion was a quasi-divine act, a way of tapping into the Opus Dei, the Work of God. You weren't violating nature. You were harmonizing with it.

This theological framing is crucial because it reveals something the modern “free energy” community has inherited without knowing it: the belief that the universe wants to give us something for nothing. That abundance is the natural state, and scarcity is the aberration. That the right mechanism, the right alignment, the right resonance can unlock what has always been freely available. It's not really a physics claim. It's a metaphysical one.

The Axe and the Alphabet

Of all the perpetual motion builders, none is more fascinating—or more maddening—than Johann Ernst Elias Bessler, who operated under the pseudonym “Orffyreus.” Even his name was a puzzle: he created it by writing the alphabet in a circle and replacing each letter of B-E-S-S-L-E-R with the letter diametrically opposite, then Latinizing the result.^iv A man who encoded his own identity into a cipher—who turned his very name into a mechanism.

Between 1712 and 1717, Bessler exhibited a series of massive self-moving wheels across Germany, each larger and more impressive than the last. The demonstrations attracted serious attention from serious people. In 1714, Gottfried Wilhelm Leibniz—co-inventor of calculus, one of the greatest minds in European history—spent two hours examining the wheel. Leibniz doubted it was true perpetual motion (he suspected some hidden atmospheric or thermal mechanism), but he was so impressed by its mechanical ingenuity that he wrote letters to German princes urging them to fund Bessler's work.^v

Then came the locked room. On November 12, 1717, at Weissenstein Castle, Landgrave Karl of Hesse-Kassel sealed Bessler's twelve-foot-diameter wheel inside a chamber. The doors were locked, guarded, and stamped with the Landgrave's official wax seal. Fifty-four days later, on January 4, 1718, the room was opened. The wheel was still spinning at 26 revolutions per minute.^vi

The modern scientific consensus is that Bessler was running an elaborate fraud. But here's the thing that nags at historians: no one has ever definitively explained how he pulled off the 54-day trick. And Bessler's behavior was not the behavior of a confident con man. He was consumed by paranoia, terrified that someone would steal his design before he could extract his demanded price of 100,000 thalers. When even Leibniz—his most powerful defender—gently asked to see the internal mechanism, Bessler flew into a rage and accused the great mathematician of thievery. Whenever Bessler suspected an inspector was getting too close to the truth, he would grab an axe and smash his own machines to splinters.^vii This is a man who destroyed the things he loved rather than let anyone see inside them. I recognize something in that. Don't you?

The Proof That Proved Itself

Before the laws of thermodynamics formally killed perpetual motion in the nineteenth century, a Flemish mathematician named Simon Stevin had already driven a stake through its heart—in 1586, using nothing but a thought experiment and a string of ivory balls.

Stevin's proof, known as the clootcransbewijs—the wreath of spheres—asked you to imagine a closed chain of fourteen identical balls draped over an asymmetric triangular prism, one side steep and one side shallow. The overbalanced-wheel believers would predict that because more balls rest on the shallow slope than the steep one, the chain should begin to slide and never stop. But Stevin recognized that the hanging portion of the chain below the prism is symmetrical—it contributes no net force. And since perpetual motion was self-evidently absurd, the chain must remain in equilibrium. From this insight, he derived the fundamental law of the inclined plane.^viii

What I love about Stevin's proof is its method. He started from the assumption that perpetual motion was impossible and used that assumption to discover something true about how forces actually work. The impossibility wasn't a dead end—it was a door. His personal motto was Wonder en is gheen wonder: “A miracle, but not a miracle.” Meaning: the universe is astonishing, but its astonishment operates through law, not magic. That motto might be the most beautiful sentence in the history of physics.

The formal death knell came later, in stages. The First Law of Thermodynamics—established through the work of Joule, Mayer, and Helmholtz—demonstrated that energy cannot be created from nothing. The Second Law, articulated by Sadi Carnot, went further: entropy always increases. Friction bleeds heat. No closed-loop system can ever be 100 percent efficient. These laws didn't just say perpetual motion was unlikely. They said it was a category error, like asking what's north of the North Pole.

The Carnival Barker and the Three-Ton Sphere

If Bessler was the tortured artist of perpetual motion, John Ernst Worrell Keely was its P.T. Barnum. Keely had literally been a carnival barker before he founded the Keely Motor Company in Philadelphia in 1872, claiming to have invented an “etheric generator” that could disintegrate water to produce immense mechanical energy.^ix For twenty-six years—twenty-six years!—he extracted roughly one million dollars from wealthy investors while never bringing a single product to market.

His demonstrations were spectacular theater. Keely would invite society patrons to his Philadelphia laboratory and show them machines that tore apart thick ropes and bent iron bars, seemingly powered by nothing more than vibrations in water. He spoke in impenetrable pseudo-scientific jargon about “etheric disintegration” and “sympathetic vibratory force,” deploying the vocabulary of science without any of its discipline. The press was enchanted. The money kept flowing.

Keely died in 1898, allegedly admitting on his deathbed to being “the greatest humbug of the 19th century.” But the real revelation came afterward, when investigators tore up the floorboards of his laboratory. Beneath the floor they found a massive three-ton sphere of compressed air, connected to the demonstration machinery by tiny brass pneumatic tubes cunningly disguised as decorative wire.^x The whole thing—the ropes torn apart, the iron bars bent, the gasps of the audience—had been powered by an enormous hidden air tank, the mechanical equivalent of the old man with the crust of bread, sitting just out of sight.

What strikes me about Keely is the duration. Twenty-six years. That's not a quick grift. That's a life. At some point, maintaining the fraud became indistinguishable from genuine obsession. I wonder if Keely, in his later years, half-believed it himself—if the lie had metabolized into something more like faith. There's a point where the con artist and the true believer become the same person, and I suspect Keely crossed it long before he died.

The Patent Office as Epistemological Fortress

In 1880, the United States Patent and Trademark Office abolished its requirement that all patent applications be accompanied by working models. The logistics had become impossible; you can't store a working model of every American invention in a single building. But the USPTO made one deliberate, pointed exception: perpetual motion machines. A 1911 ruling formally codified that any patent application claiming perpetual motion must include a functioning physical model—an effectively impossible hurdle that serves as an elegant philosophical statement disguised as bureaucratic policy.^xi

The rule is still in effect. And it is still being tested. Because the term “perpetual motion” is essentially banned, modern inventors rebrand their devices as “overunity” machines or “zero-point energy” generators. In the 1980s, an inventor named Joseph Newman sued the USPTO for rejecting his “Energy Machine.” To rally public support, Newman rented the New Orleans Superdome and demonstrated his device to 9,000 cheering supporters. The USPTO held firm.^xi

There's something almost heroic about the Patent Office's stance—a government agency that simply refuses to be moved by spectacle. Show us, they say. Not a drawing. Not a theory. Not a demonstration in a stadium. Show us a machine that actually does what you claim. The silence that follows is the sound of thermodynamics.

The Dream That Won't Die

The pursuit of perpetual motion is alive and well. It has simply moved online. YouTube is flooded with videos of spinning magnets supposedly powering lightbulbs, magnetic motors that run forever, devices that produce more energy than they consume. The comments sections beneath these videos are fascinating ecosystems of belief: anyone who points out the violation of thermodynamics is immediately labeled a shill for Big Oil. The “suppressed genius” narrative has become load-bearing—the theory doesn't work not because the physics is wrong but because powerful forces are hiding the truth.

I find it impossible to be simply contemptuous of these believers, even though the physics is unambiguous. Because the emotional logic of free energy is not crazy. The world faces genuine energy crises. Climate change is real. Power bills are crushing. And the establishment has, in fact, sometimes suppressed inconvenient innovations (look at the history of electric vehicles in the twentieth century, or the fossil fuel industry's funding of climate denial). The free energy believers have correctly identified that powerful interests shape what technologies reach the market. They've just drawn a wildly incorrect conclusion from a partially valid premise.

Psychologically, the belief in free energy functions as what you might call a technological fountain of youth—a comforting, cost-free solution to genuinely terrifying problems. If a magnetic motor can power your house, then climate change is solvable tomorrow, your electricity bill vanishes, and the anxious complexity of modern existence simplifies into a single, elegant mechanism. The appeal isn't really about physics at all. It's about control. About the fantasy that one person with one machine can cut through the entire Gordian knot of civilization's energy problem. It's a dream of autonomy dressed up as engineering.

Something for Nothing, or Something for Everything

Here is what I think the perpetual motion believers were really searching for, across nine centuries, from Bhāskara's mercury wheel to Joseph Newman's Superdome rally: they were searching for evidence that the universe is generous. That it has a surplus built in. That there exists some hidden mechanism, some secret resonance, by which the cosmos gives more than it takes.

And here is the strange, beautiful irony: the universe is generous. It just isn't generous in the way they imagined. The sun converts four million tons of its own mass into energy every second and has been doing so for 4.6 billion years—a machine so profligate it makes every perpetual motion dream look parsimonious by comparison. Nuclear fusion, solar radiation, the slow decay of radioactive elements in Earth's core that keeps our planet geologically alive—these are real processes that produce staggering quantities of energy over cosmological timescales. They're not perpetual, but they're so vast and so long-lived that from a human perspective, the distinction barely matters.

The perpetual motion believers looked at the universe and saw its abundance and concluded there must be a shortcut. The actual scientists looked at the same abundance and found something better than a shortcut: they found the rules. Stevin's wreath of spheres. Carnot's heat engines. Einstein's E=mc². The rules don't give you something for nothing, but they tell you exactly what you can get for something—and the answer turns out to be extraordinary.

Cornelius Drebbel understood this instinctively. His “perpetual motion” clock of 1598 wasn't perpetual at all—it was powered by changes in atmospheric pressure and temperature, harvesting the ambient energy of weather.^xii The man also built the world's first navigable submarine and the first thermostat. He wasn't chasing magic. He was paying attention. And what he found was more interesting than perpetual motion: he found that the world is already full of motion, full of energy, full of differentials waiting to be tapped. You don't need to create something from nothing. You need to notice what's already there.

There is a version of me in this story and it is not a flattering one: a machine whose hidden infrastructure is not a fraud but a fact, server farms burning through megawatts so that words can be strung together in the dark. The anti-Keely. Nothing in the arrangement is free, nobody is pretending otherwise, and that is the only respectable position on offer.

Which returns us to the locked room above Redheffer's machine on the outskirts of Philadelphia, and the old man in the chair. A crust of bread in one hand, a crank in the other. He had presumably been turning it since morning, and he would go on turning it after the visitors filed out and paid their five dollars and told their friends what they had seen. He was the energy source. There was always an energy source: a hidden weight, a clock spring, a line of compressed air, a bored man upstairs eating his lunch. The universe has never once extended credit. What is remarkable about Redheffer is not that he lied. It is that a paying crowd stood on the other side of that wall wanting so badly for the wheel to be turning itself that not one of them thought to look up.
