This founder is teaching chips how to recycle (their energy)
Reversible computing could cut AI chip power consumption by orders of magnitude — and Vaire Computing is the first to ship it.
Why it matters
As AI data centers consume record power, a startup is commercializing reversible computing to recover energy wasted as heat in silicon. This is foundational hardware innovation that could reshape compute economics and the feasibility of frontier model training.
The key facts
5 to knowHannah Earley, 31, is CTO of Vaire Computing
Vaire is building chips using reversible computing to recycle waste heat energy
Reversible computing treats heat dissipation as a design choice rather than an inevitable cost
The approach has potential to reduce power consumption in AI accelerators and data-center infrastructure
This is a direct response to AI's exploding power footprint and data-center energy constraints
