Vaire's Hannah Earley built a chip resonator that recycles energy
The 2025 test proved a circuit could recover net energy. Turning it into a useful processor is the harder bet.

Why it matters
Chipmakers face a power wall as AI demand climbs. Earley's resonator suggests energy recovery can work in CMOS, but Vaire still must prove it inside a useful processor.

Hannah Earley's bet at Vaire Computing moved from a basement whiteboard to a 22-nanometer test chip in 2025, when a resonator she designed recovered more energy than it consumed. The result gave an academic field with more than five decades of theory a piece of working silicon.…
