The American housing crisis of 1947 required new, modular solutions to solve a critical national infrastructure shortage. A similar modular system appears to be the only solution to our modern American AI crisis... the shortage of electricity for AI and other computing clusters.
"We cannot solve our problems with the same thinking we used when we created them.", Albert Einstein (1879–1955)
How the invention of the modular tract home solved the shortage—and what it teaches us about today's American AI electricity shortage.
Key Points:
1. Similar to other moments in American history, a tectonic shift in a critical national infrastructure market is underway. 2. This shift is leading to a supply shortage in a key American resource, computing power. 3. This supply shortage explosion is causing American leaders to seek new solutions to solve the shortage, similar to their reaction to the post-WW2 housing shortage. 4. The opens up great financial opportunities, on the order of $100s of Billions, for American innovators in possession of new solutions to meet the electricity supply shortage. 5. One such innovator is Sean M. Walsh. That's me. Years ago I anticipated this crisis, and designed, patented, and built a system to solve this American electricity supply shortage. 6. My system is called a modular Solar Computing Cluster.
Key Stats:
200,000 - WW2 era low point in annual US housing starts, due to great depression followed by wartime materials rationing, which led to nationwide housing shortage.
6,500,000 - number of American families, as of 1947, living in overcrowded conditions with friends and family, including attics, basements, garages, storage sheds, quonset huts, trailers, and even tents.
350 - the number of houses William Levitt could build per 20 day cycle, using his innovative modular assembly process.
17,447 - number of houses Levitt constructed in America's first suburb, Levittown, in Long Island, New York.
1,700,000 - number of US housing starts in 1950, due to Levitt's modular innovations.
1960 - the year by which the American housing shortage was considered solved, and unprecedented economic prosperity had taken hold, across multiple industries, like freeway construction and automobiles.The Problem: 11 Million Soldiers Return To A Home That Had No Houses For Them.
August 14, 1945.
The war was over.
From coast to coast, church bells rang and strangers hugged in the streets. In New York City, the sidewalks were confetti and brass bands. In Los Angeles, the freeways turned into parades of honking cars. For the first time in years, young men and women who had lived by the sound of sirens and the fear of telegrams could exhale.
Among them was a twenty-three-year-old Marine named David Mizrahi.
David had survived the Pacific campaign, the heat and exhaustion, the years of uncertainty. He stepped off the train in Los Angeles with his uniform pressed, his duffel bag over his shoulder, and his wife and infant son waiting with tears and open arms. What he did not have was a home.
In that first week back, David learned that his problem was not his alone.
The Great Depression had frozen construction for nearly a decade. The war that followed had turned every nail and plank into military supply. Millions of returning soldiers poured into cities that had not built anything new since 1929. Overnight, the United States faced the largest housing shortage in its history.
By late 1946, nearly four million families were without proper shelter. They lived in garages, barns, Quonset huts, and tents. Some lived in the backs of cars. In Los Angeles, David and his young family pitched a tent in Pershing Square, a park in the heart of the city that had turned into a temporary refugee camp for returning servicemen. Photographs from that time show him smiling beside his wife and toddler, their small tent standing beneath a billboard that read, Victory Bonds Build the Future.
It was a cruel irony. The men who had fought to defend the American dream could not find a place to live inside it.
That irony, however, became the seed of transformation.
The crisis forced America to think differently.
The traditional way of building homes—custom carpentry, unique blueprints, local suppliers—could not scale to meet the tidal wave of need. The backlog was too large, the costs too high, the materials too scarce. Something had to change.
Inventing The Suburb, And Modular Tract Home - How One Man Solved The Worst Housing Crisis In American History
Enter William Levitt.
“We are not builders,” said straight-talking Levitt, the operation’s mastermind. “We are manufacturers.” He even went so far as to declare his company “the General Motors of the housing industry”.
Levitt was not an architect or a politician. He was a builder with an idea. He believed that houses could be manufactured like cars, on an assembly line, using standardized parts and systematic labor. He envisioned entire communities rising from empty fields in perfect rows, each house identical in structure but affordable to the families who needed them.
It was radical. Many in the industry called it foolish, even un-American. But Levitt ignored them. He bought thousands of acres of farmland in Long Island, hired teams of returning soldiers, and began mass-producing the American suburb.
In the time it once took to build one house, Levitt and his team could build ten. By the 1950s, his methods had reshaped the entire country. Suburbs spread across the landscape like a new organism. In less than a decade, millions of families moved from scarcity to stability. The shortage was over.
And with it, a new economy was born.
The suburb did more than solve a housing crisis. It created a ripple of prosperity that reached every sector. Highways expanded. The automotive industry boomed. Appliance manufacturers grew. Schools, shopping centers, and entire new industries appeared to serve the families who now lived in those neighborhoods.
All because one man saw a bottleneck and chose to break it, not patch it.
Levitt understood something that most people miss in moments of crisis.
The biggest opportunities are never found in abundance. They are born in shortage.
Every shortage in history is an invitation to innovate the structure beneath it. Every bottleneck creates a new kind of builder.
And the one who builds the system that removes the bottleneck does not just fix a problem. He owns the future that follows.
Parallels To Today's US Electricity Shortage For AI
The patterns are the same.
The builders of 1947 were told their vision was impossible. They were mocked for breaking tradition. They were warned that people would never accept such uniformity, such efficiency, such speed. And then the need became undeniable. The skeptics ran out of arguments. The impossible became inevitable.
That is exactly where we are today.
The critics will say the grid can adapt, that new plants and renewable projects will rise in time to meet the surge. They will point to statistics, policies, and committees. But the numbers do not lie. The timelines do not match. The approvals will not arrive before the demand.
We are watching the same story unfold again, only this time the stakes are measured not in mortgages and two-car garages but in the future of computation, sovereignty, and national security.
When the veterans of 1947 camped under that Victory Bonds billboard, they had no idea they were living through the birth of a new civilization. They only knew that the old one had run out of room. The same is true for us.
Our Nation has outgrown its electrical infrastructure.
And just as Levitt once looked across an empty field and saw not farmland but opportunity, the builders of this new era must look at sunlight and see the next foundation of civilization.
Necessity Is The Mother Of Invention
When David Mizrahi stood beside his tent in Pershing Square, he could not have imagined that within a decade his family would live in a new home with running water, electricity, and a white picket fence. He could not have predicted that his son would grow up in a generation that never worried about shelter. He only knew the struggle of the present.
That is how shortages feel when we are living through them. Endless. Permanent. Unsurvivable.
But every shortage ends the same way—when someone looks at what exists and decides it is not enough.
Levitt did not wait for permission. He built the solution before the world was ready to ask for it. And because he did, his name became synonymous with a new way of living.
The next Levitt will not build homes. The next Levitt will build energy.
And once again, the future will belong to the builder who sees the pattern and acts before the rest of the world understands it has begun.
History May Not Repeat, But It Often Rhymes
There is a photograph of William Levitt taken in 1948. He stands in the middle of a field surrounded by half-built homes, a clipboard in one hand and a cigarette in the other. Behind him, rows of identical roofs stretch into the horizon. In that photograph, you can see the future forming around him—organized, efficient, and unstoppable.
If you look closely, you can almost see the same horizon forming now, not in fields but in deserts and plains where sunlight and computation will meet.
History does not repeat itself in detail, but it does rhyme.
The rhyme is always the same: crisis, invention, prosperity.
The question is never whether the shortage will end. It is who will end it.
In 1947, it was a builder who refused to accept that old systems could meet new demands. In our time, it will be the visionary who understands that the grid is not broken. It is simply complete. Its era is over.
What comes next will not look like an extension of the old world. It will look like the beginning of a new one.
The suburb of the twenty-first century is not a neighborhood. It is a decentralized network. It is a cluster of power and intelligence, self-contained and self-sustaining.
It is the Solar Computing Cluster.
