You might try caches_action
in your controller. It will create the static version and save it. You could either create it in dev and checkin, or have it generated in production. You'd need to fine a way to delete it in production if it's not checked in. Requires caching to be turned on.
If you are OK with checking it in - you can always save from the browser.
Basically - if there is a file in public at the same location as the view, it will be served instead of the dynamic one.
