Founder Hannah Earley teaches chips to recycle energy

hannah earley, 31, cofounded vaire computing to commercialize reversible computing, an old idea that aims to recover energy from waste heat in computer chips. conventional chips erase information during calculations, dissipating energy as heat, while reversible computing retains this information to recover some energy. earley designed a patent-pending resonator that stores recovered energy for later reuse. last year, vaire announced a breakthrough: a chip that recovered more energy than it lost. the technology is early-stage, but earley thinks it could make data centers and devices much more energy efficient. vaire has raised over $12 million and hired reversible computing pioneer michael frank as a senior scientist.
