Frederick W Kantor's 1977 book _Information Mechanics_ says that energy must correspond to information, and then works out consequences
That can't be right--they have different units!
Doesn't that depend what units you think a bit is in?
Perhaps energy corresponds to information *at a given temperature*. Landauer's principle says the energy required to erase a bit is
E >= k_B T ln 2
Since Landauer is talking about erasing a bit, while Kantor considers information conserved, I don't think these relate, or maybe they relate like available vs. total energy. I'm pretty sure Kantor's bits (unlike Verlinde's) are not about thermodynamics but about grain in the possible states of the underlying system. Maybe you can make some sense of his math & use of units here, I can't: http://www.gravityresearchfoundation.org/pdf/awarded/1974/kantor.pdf --Steve
