Thrust 2: Capital Efficiency

Hardware manufacturing accounts for a large and growing share of computing’s environmental impact. This thrust develops strategies to reduce embodied costs through a “reduce, reuse, recycle” framework. Reduce targets fabrication costs through heterogeneous integration and 3D stacking. Reuse extends hardware lifespans via disaggregated architectures that decouple component upgrade cycles. Recycle enables secondary hardware markets through wear-level tracking that establishes residual value and remaining useful life.

Key Research Questions

  • How much embodied carbon can chiplet-based and 3D-integrated designs save compared to monolithic fabrication?
  • Can datacenter disaggregation extend hardware utilization by decoupling component lifecycles?
  • What mechanisms and market structures support reliable secondary hardware markets at scale?
