What if nuclear energy didn’t mean 10-year construction timelines, multi-billion-dollar budgets, and massive gray concrete towers on the skyline? What if reactors could be built in factories, shipped where they’re needed, installed in months, and designed so beautifully you wouldn’t mind seeing one nearby? In this premiere episode of Decarbonizers, host Idrees Madni sits down with Yasir, co-founder and CTO of Aalo Atomics, to unpack a bold new vision for nuclear power. Yasir’s story starts in Bangladesh, studying by candlelight during daily power outages. That early frustration turned into curiosity, then into a career. He went from taking apart stereos as a kid, to joining Westinghouse as Fukushima reshaped the industry, to leading advanced reactor design at Idaho National Laboratory, and eventually launching Aalo Atomics to fix what traditional nuclear got wrong. He explains how “economies of scale” quietly became “economies of size,” making plants slower and more expensive. Microreactors flip that model to “economies of numbers,” small, repeatable, factory-built systems. With liquid metal cooling and physics-based safety, these designs aim for true “walk-away safe” operation. Even nuclear waste gets a fresh look, reframed as a manageable engineering challenge rather than an unsolvable crisis. From powering AI data centers to creating beautiful, community-friendly plants and enabling modern “micro Bell Labs,” this episode reimagines nuclear as fast, scalable, and human-centered. Not a relic of the past, but a serious contender for a decarbonized future. If you care about the future of clean power, advanced technology, or rebuilding infrastructure at scale, this episode is a must listen. Key Takeaways Why nuclear energy has a speed and cost problem, not a physics problem The difference between scaling by size versus scaling by manufacturing volume How microreactors can be built as products instead of mega construction projects Why Aalo is targeting AI data centers first How physics-based safety reduces complexity and cost Why nuclear waste is more manageable than most people think The vision for factory-built reactors producing a gigawatt per year How decentralized nuclear could reduce grid dependence Why learning velocity is a founder’s greatest advantage In This Episode: [00:00:00] - Dynamic Intro [00:01:27] - Introduction [00:02:18] - Early Inspiration in Bangladesh [00:03:39] - Climate Change Realities [00:04:52] - Discovering Nuclear Energy [00:06:58] - Career at Westinghouse [00:09:33] - Learning from Large-Scale Projects [00:11:58] - The Arctic Inspiration.
