Repair Inspiration: Refrigerators That Don’t Need Electricity

Refrigerators – those blessed, buzzing boxes that keep our ice cubes frozen, our milk unspoiled, and our vegetables crisp – are serious energy hogs. In most homes, they use up more energy than any other appliance, and lead to unintended food waste. Meanwhile, in countries where energy is scarce, the lack of refrigeration can also lead to food waste.

According to an article (and awesome slideshow) on Co.Exist, it doesn’t have to be that way. Check out the excerpt below about a clay fridge by a company called MittiCool that does not require electricity, and read the whole thing on Co.Exist’s website:

Clay Fridges That Keep Food Cool Without Electricity
By: Ben Schiller

According to the U.N. Food and Agriculture Organization, the world wastes an astonishing 1.4 billion tons of food a year. This while plenty of people are still starving, and while many countries spend large percentages of their income to feed themselves.

Reasons for food waste differ from developed to developing worlds. In rich countries, it’s usually the food consumers who are responsible–i.e. people just throwing away excess food that they haven’t eaten or that spoiled before they could. In poorer nations, the problem tends to be in the supply chain. Because of poor refrigeration, food rots during transport or spoils at market stalls because it’s not sold quickly enough.

Made from clay and not needing any power to run, it keeps vegetables fresh for up to a week and can even store dairy, according to Mansukhbhai Prajapati, its Indian inventor.

The fridge is made of a porous type of clay from Gujarat, the region in India where Prajapati has his workshop. You feed water into a 5 gallon holding tank at the top and it gradually drips down through the material. On a warm day, the water evaporates, cooling the clay and leaving the contents inside relatively cold. Prajapati says the fridge is eight degrees Celsius less warm than room temperature.

“The fridge is not harmful for our health. It’s totally eco-friendly. And there is no maintenance like other refrigerators,” Prajapati points out. It’s also relatively cheap. Models cost about $50.

Repair Inspiration: Eat Vegetarian, Cut Your Carbon Footprint

There are lots of ways to “eat green” and live an eco-friendly lifestyle, but a new report published in the journal Climactic Change suggests that one of the best things you can do to lower your carbon footprint is to eat a vegetarian diet.

Whether you are a long time vegan or not a fan of the idea of living meat free (on Meatless Monday or any day), check out this story excerpt below, or read the whole thing on The Huffington Post.

Vegetarianism Cuts Your Dietary Carbon Footprint A Ridiculous Amount, Study Finds
By: Joanna Zelman

As the economic, political and personal costs of doing nothing to mitigate climate change skyrocket, there’s one lifestyle change that slashes dietary greenhouse gas emissions in half: Veganism.

Climate change is predicted to cost the U.S. billions of dollars by mid-century, poses a growing national security threat, and will make some regions of America “unsuited for outdoor activity.”

A new report published in the journal Climatic Change compared greenhouse gas emissions attributable to more than 55,000 meat-eaters, fish-eaters, vegetarians and vegans in the U.K. The researchers found that meat-eaters’ dietary greenhouse gas emissions were twice as high as vegans’.

The production, transportation and storage of food greatly contributes to emissions, the study points out. These emissions range from carbon dioxide related to fossil fuels used to power farm machinery, to the methane released by livestock. Animal-based products tend to release more emissions than plant-based products due to the methane animals can produce and the inefficiencies in growing livestock feed.
