DailyDirt: No Refrigeration Necessary...?

from the urls-we-dig-up dept

For centuries, people didn't have convenient refrigeration for storing food for long periods of time. Nowadays, we take refrigerators for granted and keep things in them even when it's not necessary. Here are just a few cool examples of ways to avoid eating spoiled food.

• There's a prototype for a sustainable portable refrigerator for small volume containers that doesn't require electricity. It still needs to be heated up in some way for the thermodynamics of it to work, but it's an interesting self-contained device for remote locations... or for camping trips? [url]
• Some nicely-designed containers could help folks store food without refrigeration while still keeping food fresh. Storing eggs at room temperature seems really strange to most Americans. [url]
• Mohammed Bah Abba won a Rolex Award for re-discovering a pot-in-pot refrigeration device (aka a zeer) that can keep food cool by taking advantage of evaporative cooling. A zeer costs about $1 to make and is just a couple of nested clay pots with wet sand between them. [url]

By the way, StumbleUpon can also recommend some good Techdirt articles, too.
