It works well with rice cookers with delay timers (which are as cheap as $35). You prepare the rice the night before and put it in the rice cooker, then set the delay timer to right before you wake up. Once you wake up, put the cooked rice into a container and into the fridge; when you return home it's done.

You can cycle this process every 12 hours by having new rice on a delay when you leave for work, so it's cooked when you return home and you can put that in the fridge for the morning or lunch. It may not be 12 hours exactly but it's close. Or just save big batches.
