Radiant’s mobile 1-megawatt reactors and Heron’s 5-megawatt transformers target America’s power-delivery bottleneck as data centers expand.
Radiant CEO Doug Bernauer and Heron CEO Drew Baglino, speaking with a16z’s Erin Price-Wright and Erik Torenberg, trace their energy ventures to work at SpaceX and Tesla. Bernauer says Radiant is developing trailer-sized, 1-megawatt microreactors that could reach a site and provide power within 48 hours for five years; the company targets off-grid customers facing costly diesel, not utility-scale generation. Baglino describes Heron Link, a 5-megawatt bidirectional solid-state transformer designed to connect DC sources to 34,000-volt AC distribution, using modular power electronics. Both argue that electricity delivery—not new generation—is the key constraint, and favor factory-built, scalable infrastructure. They discuss nuclear milestones, fuel and waste challenges, and the potential for data centers to support grid economics: their steady demand can raise system utilization and lower average costs, though sudden disconnections can destabilize the grid without better controls.
