Vaire Computing Built a Resonator That Recovers More Energy Than It Costs to Run

Vaire Computing, cofounded by CTO Hannah Earley (31) with Rodolfo Rosini and reversible-computing pioneer Michael Frank as senior scientist, announced a chip whose resonator recovered more energy than it lost even after accounting for the power needed to drive the component. The approach is reversible computing: retain information from intermediate computation steps rather than erase it, so the energy normally dumped as heat is recycled. The company has raised over $12M and is at proof-of-concept, now working on folding the design into existing manufacturing flows; outside experts say it needs a series of increasingly realistic demonstrations before industry commits.
