Nuclear submarines can stay submerged for 90 days, limited by their food supply, not energy. The onboard nuclear reactor provides limitless power to convert seawater into breathable air and water, demonstrating how a single technological leap can completely redefine a system's constraints.

The U.S. Navy's ability to track Soviet submarines while keeping its own hidden threatened the USSR's second-strike capability, the cornerstone of nuclear deterrence. This technological and financial asymmetry pushed the Soviets toward de-escalation and ultimately, ending the war.
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.
Google's research head distinguishes between innovation—the continuous, iterative process of improvement applied across product and research—and true breakthroughs. Breakthroughs are fundamental shifts that solve problems not previously solvable in principle, such as the Transformer architecture that underpins modern AI.
The key driver for military adoption of micro-reactors isn't cost savings, but eliminating the vulnerability of fuel supply chains. Fuel logistics accounted for 50% of casualties in Afghanistan. This frames the product's value around mission assurance and risk reduction, a more compelling proposition than simple energy provision.
Facing immense electricity needs for AI, tech giants like Amazon are now directly investing in nuclear power, particularly small modular reactors (SMRs). This infusion of venture capital is revitalizing a sector that has historically relied on slow-moving government funding, imbuing it with a Silicon Valley spirit.
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.
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.
To secure the immense, stable power required for AI, tech companies are pursuing plans to co-locate hyperscale data centers with dedicated Small Modular Reactors (SMRs). These "nuclear computation hubs" create a private, reliable baseload power source, making the data center independent of the increasingly strained public electrical grid.
Nubar Afeyan argues that companies should pursue two innovation tracks. Continuous innovation should build from the present forward. Breakthroughs, however, require envisioning a future state without a clear path and working backward to identify the necessary enabling steps.
Critics question whether deep tech startups are doing "novel science." However, the strategic goal is often not a new discovery, but making a proven but abandoned technology (like nuclear fission) economically viable and scalable again. This demonstrates that for reindustrialization, effective execution on proven tech can be more valuable than chasing purely scientific breakthroughs.
