clearing bits far away from computation
Irreversible computing can be done as reversible computing plus bit clearing. Swapping bits is reversible. You don't have to clear bits at the same place that computation consumes zeros. You could clear bits someplace safe to generate heat, toss a bunch of bits to the computation, swap zeros for random bits, then toss the random bits back to be cleared again.

Does that help with making computation compact and low temperature?
