Story summary

Ice River, a chip from Vaire Computing, recovers energy instead of dissipating it as heat.
In August tests, it used 30% less energy than standard chips, using reversible logic and adiabatic computing.
Experts say the approach is promising but faces scaling and adoption hurdles, and slower processing could raise costs.
