What if a chip could recover energy instead of losing it as heat? That question is driving two semiconductor developments: Vaire Computing is building chips around reversible computing, while Huawei Technologies has presented an architecture designed to keep denser chips from overheating.
The approaches are different, but they target the same pressure point. Modern chips must do more work without wasting energy or turning every performance gain into extra heat. Vaire is exploring energy recovery at the component level, while Huawei says its Kirin 2026 chip can pack in more transistors and still run cooler than its predecessor.
Vaire’s Chip Tries to Reclaim Lost Energy
Hannah Earley, cofounder and chief technology officer of Vaire Computing, is working on chips that recycle energy usually thrown away as heat. The company uses reversible computing, an idea first proposed more than 50 years ago, to rethink how energy moves through electronic circuits.
Vaire announced a chip with a resonator that recovered more energy than it lost, even after counting the energy needed to power the component. That result centers on a tiny part with a specific job: storing recovered energy so the chip can reuse it later.
Earley designed a patent-pending type of resonator, a microscopic chip component that stores recovered energy for later reuse. She describes the device in simple terms: “It’s really a glorified pendulum.” The comparison points to a component that holds energy and gives it back instead of letting it disappear as heat.
That work grows out of an early interest in computing. Earley began programming around the age of nine, then studied at the University of Cambridge under Gos Micklem, a computational biologist and her PhD advisor. She completed her degree in 2021.
Her path from programming to chip design also included a striking period of hands-on work. In winter 2022, Earley spent weeks in her now-wife’s basement in Grinnell, Iowa, working on circuitry schematics.
Rodolfo Rosini, a technology entrepreneur and investor, co-founded Vaire with Earley. The startup has raised more than $12 million, giving the company resources to pursue a concept that reaches back decades but aims at today’s energy problem.
Earley’s ambition extends beyond one component or one chip design. “I want to tackle every part of how computers are built, and rethink it in these terms,” she said.
Huawei Targets Heat as Transistors Multiply
Huawei Technologies is attacking the same broad challenge from another direction. On September 6, 2026, the company released a research paper showing that its Tau Scaling Law-based semiconductor architecture can avoid overheating.
He Tingbo authored the paper. She serves as chairwoman of the Huawei Scientist Committee and president of Huawei’s semiconductor business department. The paper appeared on ChinaXiv, a platform for scientific papers that have yet to be peer reviewed.
The research focuses on Huawei’s Kirin 2026 chip, which ran cooler than its predecessor despite packing 55 percent more transistors per square millimeter. The chip also cuts power use by up to 66 percent on some key tasks.
That combination puts density and power use at the center of Huawei’s claim. More transistors can support more computing capacity, but the chip must manage the energy those transistors consume. Huawei says its architecture addresses both demands at once.
Kaiyuan Securities described the design this way: “The new chip reduces power consumption while increasing transistor density, allowing it to flexibly switch between functional constraints and peak performance.”
Two Paths Toward More Efficient Computing
Vaire and Huawei are not presenting the same technology. Vaire is building around reversible computing and a resonator that recovers energy for reuse, while Huawei is applying the Tau Scaling Law to a semiconductor architecture designed to avoid overheating.
Still, the goal connects them. Vaire is focused on energy that circuits normally lose as heat, and Huawei is focused on keeping a denser chip within manageable thermal limits. Both developments ask the same question: how much more computing can semiconductor design deliver without paying for it in wasted energy?
Igor Markov, commenting on Vaire’s work, said, “It’s clear they have something interesting.” That interest reflects the challenge facing chip designers as every part of computing pushes against limits set by heat, power, and density.
The next stage for both efforts will depend on how these designs perform beyond the reported results. Vaire is pursuing a chip that reuses energy at the component level, and Huawei has presented a chip that combines higher transistor density with lower power use on some key tasks.
The semiconductor race is no longer only about adding more transistors. It is also about making every unit of energy count, whether a chip recovers power that would become heat or reshapes its architecture to run cooler under greater density.
