Peter Diamandis predicts that new, safer nuclear technologies like fusion will be deployed by replacing the boilers at existing coal plants. This strategy leverages the plant's existing power lines, supply chains, and, crucially, its permitted footprint, accelerating the transition to cleaner energy.

Today's nuclear energy boom is propelled by strong commercial demand from AI data centers and defense, not government R&D. This market-driven "demand pull" for energy is finally creating the business case for advanced and small modular reactors.
Radically departing from the traditional model of massive, on-site construction, Radiant is designing portable micro-reactors to be mass-produced in a factory. This "reactor as a product" approach aims to deliver power solutions that can be shipped and activated in 48 hours.
The massive energy consumption of AI has made tech giants the most powerful force advocating for new power sources. Their commercial pressure is finally overcoming decades of regulatory inertia around nuclear energy, driving rapid development and deployment of new reactor technologies to meet their insatiable demand.
The primary flaw in nuclear energy economics is that every plant is a unique, bespoke construction project, leading to massive cost overruns. The solution is to treat nuclear power plants as standardized, factory-produced products, much like cars, to achieve predictability, speed, and cost reduction through scale.
The 40-year plateau in nuclear power wasn't driven by public fear after incidents like Chernobyl, but by the soaring costs of building massive, one-off reactors. The modern push for Small Modular Reactors (SMRs) aims to solve this fundamental economic problem through factory-based production.
To power energy-intensive AI data centers, tech companies are willing to build their own energy sources, specifically small modular nuclear reactors, which could make them net energy suppliers. The primary obstacle is not technology or willingness, but regulatory hurdles and staunch environmental opposition.
Despite nuclear power's poor public image based on fission, significant advances in fusion technology are positioning it as a potential solution for clean, abundant energy. We may look back on 2026 as the year this shift became viable.
TerraPower's advanced nuclear reactor design can use depleted uranium—currently treated as waste—as fuel. The amount of this material already stored in a single U.S. facility is sufficient to meet the entire planet's energy needs, carbon-free, for hundreds of years.
After massive cost overruns on traditional nuclear projects, no utility will build a Small Modular Reactor (SMR) alone. The only viable path forward is for a tech giant to provide both a purchase agreement for the power and direct equity investment in the SMR manufacturer to fund capital expenditures.
Conventional water-cooled reactors can't reach the high temperatures needed for industrial processes like steel and concrete production. Advanced reactors using coolants like sodium can operate at 500-800°C, unlocking the ability to decarbonize the massive industrial process heat market, which accounts for nearly a quarter of global energy consumption.
