  And when have to do error correction and to erase bits, you primarily  focus on moving bits reversibly from your system into the negentropy store. The resource that you fundamentally have in your storage is negentropy. It can be stored in different ways and converted between those ways, but the way to count it is as negentropy.
Yes, but making one bit of negentropy, doesn't that cost kTln(2)? (where T is the *current* temperature)
