No Power, No AGI. The Race to 2027 Just Hit a Wall. The Billionaires Know It.
Rob Walton just took a board seat in a nuclear startup. Sam Altman is backing thermal batteries for data-centers. Microsoft reopened Three Mile Island. Here is what they see that you do not yet.
Your AGI might never happen (at least on the B2C side), just because we do not have enough energy. What does it mean for the Quiet Renaissance?
A few months ago, NuCube Energy closed $13 million with Rob Walton personally investing and joining their board. Rob Walton is the eldest son of Walmart founder Sam Walton. His family office manages over $200 billion. He does not write small checks into random tech.
NuCube co-founder Dr. Cristian Rabiti presented on our stage at the USS Hornet last month. The thesis: a high-temperature modular microreactor delivering 15 MW of power for up to 30 years. No moving parts. Industrial heat up to 1,100°C. Designed for data centers, manufacturing campuses, and remote operations.
This is the same pattern we saw last year when Walton’s family office backed Oklo before its 100x SPAC run. The same pattern when he took a board seat at a fusion company before the sector exploded.
Rob Walton is not betting on nuclear because it is trendy. He is betting because Walmart needs power. Amazon needs power. Every hyperscaler needs power. And the grid cannot deliver.
The billionaires are building their own energy empires.
Microsoft reopened Three Mile Island. Google signed the largest corporate nuclear PPA in history. Amazon is buying reactors. Musk built natural gas turbines directly at Colossus because Memphis could not supply power fast enough. Sam Altman backed Exowatt and Helion.
Data centers consumed 2% of global electricity in 2022. By 2026, that number doubles. By 2030, AI data centers alone will consume more electricity than Canada.
Hyperscalers are spending $1 trillion in 2025-2026. Half of that is energy infrastructure.
The companies solving this problem are the next infrastructure layer of the AI economy. NuCube was on our stage. Exowatt is in our dealflow. The proof points keep stacking.
The grid is the bottleneck. The billionaires know it. Now you do too.
I. WHAT IS A RENAISSANCE
Three weeks ago, I stood on the flight deck of the USS Hornet in San Francisco Bay and told 110 family offices something I had been thinking about for months.
I said:
“For the past 52 years, humans stopped dreaming. We built energy infrastructure. We built highways. And then we sat back and relaxed. When I was a kid watching Star Wars, I thought I would grow up to see robots and spaceships. Where is all that? As a millennial, I feel sometimes very sad. We feel like there’s nothing more to build, nothing else to explore… We feel useless.”
Then I said:
“Very recently, I realized this feeling was wrong.”
Because something is happening right now. This year. This decade.
Every industrial revolution in history has had three layers. A new energy. A new communication. A new transportation. When all three shift at once, you get a Renaissance.
The First Industrial Revolution: Coal. Telegraph. Railway.
The Second Industrial Revolution: Electricity. Telephone. Automobile.
The Digital Revolution: The grid. The internet. Global logistics.
The Quiet Renaissance: All three layers are being reinvented. Right now. At the same time.
Layer 1: New Energy
Solar at near-zero marginal cost. A nuclear renaissance with 120+ reactor designs in development. Thermal storage that makes solar dispatchable 24/7. Geothermal unlocking baseload anywhere on earth.
Rob Walton just invested in NuCube, a microreactor delivering 15 MW for 30 years with no moving parts. Sam Altman backed Exowatt, thermal batteries targeting 1¢/kWh. Microsoft reopened Three Mile Island. Google signed the largest corporate nuclear PPA in history.
For the first time since the 1970s, energy abundance is not a constraint. It is a design choice.
Layer 2: New Communication
AI and the Internet of Things are no longer tools we operate. They communicate with each other. They make decisions themselves. Machines coordinating with machines, without a human in the loop.
The communication layer is no longer about connecting people. It is about autonomous intelligence. Agents talking to agents. Systems optimizing systems. The infrastructure layer of the AI economy is being built right now.
Layer 3: New Transportation
Self-driving utility trucks. Humanoid robots cleaning homes and running warehouses. Robotics going places humans physically cannot. Space colonization as the new frontier.
Figure AI is producing one humanoid every 90 minutes. Foundation just closed $24 million in Pentagon contracts. Prometheus raised $16 billion in six months to build the AI layer for the $30 trillion manufacturing economy.
The transportation layer is no longer about moving humans faster. It is about extending reach beyond human limits.
The Signal
On the USS Hornet, I looked around the room. $500 billion in family office capital. $50 billion in venture capital. Founders who had raised billions. All in one afternoon. On the same deck that recovered the Apollo 11 crew 52 years ago.
I said:
“The quiet builder in Singapore who is building a new kind of hydrogen catalyst. The new builders of nuclear power. The quiet family office who doesn’t have a beautiful LinkedIn page but is investing millions to shape the next generation of products my kids will use. This is what I call the Quiet Renaissance. And because you decided to be here today, you are already part of it.”
The families writing checks into this space understand. They are not betting on quarterly returns. They are betting on structural transformation.
NuCube was on our stage. Three weeks later, Rob Walton joined the cap table.
Exowatt is in our dealflow. Sam Altman backed it before the headlines caught up.
The New Renaissance is not coming. It is here.
II. THE MACRO THESIS: The Energy Bottleneck Is the AI Bottleneck
Global investment in the power industry hit a new high of $1.5 trillion in 2025. Off-grid solutions are a key area where investors are seeing value creation.
By 2035, global data centers will consume nearly 3x the electricity of France, (my country) of 68 million people powered by 57 nuclear reactors…
The numbers are staggering.
Global data center power consumption is projected to increase 165% by 2030 (Goldman Sachs). A single H100 GPU draws 700 watts. A cluster of 100,000 H100s, a scale that multiple companies now operate, draws 70 megawatts continuously.
Grid interconnection takes 5+ years. AI demand doubles in 2.
The thesis is simple: whoever solves dispatchable, deployable, cheap energy wins the AI infrastructure race.
Off-grid, behind-the-meter solutions are the only path that scales in time. Natural gas, microgrids, batteries, nuclear, and hybrid systems are gaining momentum as data centers “bring their own power.”
Morgan Stanley estimates hyperscalers will spend $1 trillion or more in 2025-2026 alone. A big focus for credit markets in 2026 will be securing this financing. The upcoming infrastructure CapEx cycle will create islands of wealth, and literal power.

III. INVESTMENT OF THE WEEK: EXOWATT
The Holy Grail of Solar: Dispatchable, 24/7, 1¢/kWh
Company: Exowatt Founded: 2023 HQ: Miami, Florida (new Austin campus March 2026) Raised: $140M in under two years Demand backlog: 90+ GWh
Learn more details at: https://wetheatlas.com/solutions/6a073bf4cd40eafa9503cd78
The Technology
Exowatt P3 is a modular, dispatchable solar system. It captures solar energy and stores it as heat in ceramic and rock materials heated to over 1,200°C. Steam turbines convert that heat to electricity on demand, day or night.
This is the holy grail of solar: baseload power without intermittency.
The system is factory-built in the United States using abundant low-cost materials. No rare earth minerals. Domestic supply chain. Container-sized modules that can be co-located at data centers without grid interconnection.
The Thesis
The target: 1¢/kWh. That is 90% cheaper than current grid rates.
The bottleneck for AI is not compute. It is power. Grid interconnection takes 5+ years. Exowatt can deploy in months.
“AI demand won’t wait for new transmission interconnections. Exowatt’s dispatchable, American-made solar puts firm, clean power at the edge of load.” — Andre de Baubigny, MVP Ventures
“Exowatt is converting momentum into megawatts.” — Rayyan Islam, 8090 Industries

Why It Matters
Data centers already consume about 1% of global electricity. AI workloads could push that to 3-4% by 2030. Traditional renewables cannot match AI’s constant power demands without massive storage.
Exowatt’s thermal batteries never degrade. The rocks and ceramics maintain heat for about five days. Unlike lithium-ion, which loses capacity over endless charging cycles, Exowatt’s system has no cycle degradation.
The company has a demand backlog exceeding 90 GWh from data centers, energy developers, and hyperscalers across the US. Several commercial deployments are going live in 2025-2026.

V. THESIS: Three Structural Tailwinds
Tailwind 1: Grid interconnection is broken.
5+ years to connect to the grid. AI demand doubles in 2. Behind-the-meter is the only path. Data center operators are searching for alternatives to constrained utility capacity across the US.
Tailwind 2: Hyperscalers are becoming energy companies.
Amazon, Google, Microsoft, Meta, xAI, Oracle, OpenAI are all building or contracting their own power generation. The buyer is the builder now. This shift from energy consumer to energy producer is one of the least-covered but most consequential developments in tech in 2026.
Tailwind 3: Dispatchable renewables are the unlock.
Solar and wind are cheap but intermittent. Thermal storage makes them baseload. Whoever cracks dispatchable solar at scale wins. Exowatt’s P3 is designed for exactly this: firm, sustainable capacity that data centers require while reducing dependence on constrained grid interconnection.
VI. Five Signals to Monitor in Q2 2026
01 · Exowatt Commercial Deployments Several commercial deployments going live in 2025-2026. Watch for named data center customers and capacity announcements.
02 · NuCube Regulatory Progress With $13M secured, the company will continue materials testing and advance regulatory engagement. Watch for licensing milestones.
03 · Kairos Power / Google SMR Timeline Early 2030s target for SMRs to come online. Any acceleration or delay moves the sector narrative.
04 · Helion Fusion Plant 2028 target for first plant with Microsoft as anchor customer. Watch for construction updates.
05 · xAI Colossus Power Expansion 2 GW compute capacity, 1M+ GPUs. Musk’s SpaceXAI controls the largest private compute cluster. Power source expansion is the signal.

VII. THE QUIET RENAISSANCE VIEW
In 1968, Aurelio Peccei of Fiat and Alexander King of the OECD gathered 35 industrialists and scientists in a villa in Rome. They commissioned MIT to model the future of civilization. The result was “The Limits to Growth,” and it shaped fifty years of scarcity thinking.
In 1973, David Rockefeller and Zbigniew Brzezinski convened bankers, politicians, and executives from the US, Europe, and Japan. They called it the Trilateral Commission. A young governor named Jimmy Carter attended before anyone knew his name. They designed the globalization playbook the world ran on for the next half century.
Every few decades, a small group of people gathers in a room and quietly decides what the next century will be built on. The rest of the world only notices later.
I believe we are in one of those moments now.
NuCube presenting on our stage before Rob Walton joined their round. Exowatt in our dealflow before the headlines caught up.
This is what the Quiet Renaissance looks like: the builders and the capital finding each other before the rest of the world notices.
The thesis is beyond climate tech. It is not ESG. Building vital infrastructures to build a world where nature and technology co-exist for generations.
The families writing checks understand. They think in generations, not quarters.
Fight the Good Fight.

the power thing is so obvious in retrospect but nobody was talking about it 6 months ago. now it's like compute went from budget line item to strategic asset and everyone's acting surprised
