I was just thinking of normal, non-reversible computation, constrained to dissipate at most
one watt of heat.

Do any reversible computing devices currently exist?  (Yes, I know a NOT gate exists, but I
mean something computationally more powerful than that, preferably Turing-machine-equivalent,
and specially designed to use the properties of reversible computation to minimize power
consumption.)

There sure are. One of the papers apparently describes a simple 8-bit reversible CPU.
