Not only will you save energy...

apparently you can also contribute to a more tightly knit, liveable and sustainable community. This is an interesting read.

Small fridges make good cities, but American fridges just keep getting bigger

Reminds me of something I saw years ago on "The Nature of Things". It was a special about green homes and building techniques. There was one home that looked like a series of underground onions, but where the shoots should be there was a round skylight to let light in, with the onion rooms connected by tunnels. They were all connected by tunnels, and they were naturally heated and cooled largely by the earth that surrounded them.
The coolest part (no pun intended) was the fridge that the designer had made. He recognized that a big flaw with the fridge design that we all see in our homes is that they open vertically, so that all the cool air (which is more dense fluid and sinks) pours out when the fridge is opened. That's why I get so frustrated when I see "new energy efficient" fridges that have a bottom freezer with a drawer instead of a door. Especially when that drawer is not solid but is a wire basket. Not only is the cold air going to flow out, but the food is all moved out into warm air without even a solid barrier to isolate it form the warmth of the kitchen. Any air cooled by the food will fall onto the floor as well, instead of back into the freezer.
Anyway, back to the well designed fridge. It was circular, with a pneumatic lift in the center. When you wanted to grab the ketchup or whatever you needed, the button is pressed and the food lifts out on wire shelves (admittedly exposing all the food to warmth) BUT the cool air is left within the fridge itself so that an entirely new mass of air does not need to be cooled. WHAT SAVINGS!

Think of the air in your fridge as cold water. You open the door, and it pours out all over your kitchen. But if you're at the cottage and you grab a beer out of the kiddy pool full of ice, you don't have to let all the water out. You just grab what you want and leave the cool fluid behind.
Heavenly!
