I would guess that the relationship of the annual solar limit (total annual
energy output of the sun?) to cryptography would be that one can peg an
energy cost for each computer instruction. One can then calculate in a rough
way the capacity of a theoretical computing unit whose energy source is the
sun. Seems like a fairly arbitrary measure, but then, in science, most are.

| The yearly energy output of the sun is a unit in common use
| in astrophysics (never mind the solar-system-centric point of view).
|
| For instance when I was still an astrophysicist, I would
| discuss clusters of galaxies in terms of their luminosity,
| usually calibrated to solar luminosity.  Leads to ridiculously
| large numbers.
|
| I am not personally aware of anyone other than Rick using the
| term as a benchmark for brute force attacks.  But people do frequently
| refer to the length of time to search a particular key space in
| terms of multiples of the age of the universe, so it's not much
| of a stretch.
