John's idea of storing data in a perpetual fiber loop gave me an idea.

Instead of storing food in a fridge, we can put it in a spinning device that accelerates to 99.5% of the speed of light. Because of time dilation, time will pass 10x slower for the food, keeping it fresh much longer without the need for refrigeration.

In hindsight, this idea may have a flaw. I didn't factor in centripetal force, which would likely smush the food.

The food would have to be sent into space in a straight line, decelerate safely, and turn back.

The downside is that, unlike a fridge, you cannot access your food on demand.
