This founder is teaching chips how to recycle their energy

Hannah Earley, cofounder and CTO of Vaire Computing, is pioneering the development of reversible computing to address the massive energy waste inherent in modern computer chips. Conventional processors dissipate energy as heat when they erase information during calculations. Earley’s startup has developed a patent-pending resonator—a microscopic component that acts like a pendulum to store and reuse energy instead of discarding it. Last year, Vaire achieved a significant milestone by demonstrating a chip that successfully recovered more energy than it consumed. While the concept of reversible computing has existed for decades, practical implementation remained elusive until Earley’s hardware innovations. Although the technology is still in its early stages, the company has secured over $12 million in funding to move toward commercialization. Experts suggest that while the breakthrough is promising, Vaire must now demonstrate the scalability and reliability required to influence the broader semiconductor industry.
