There are over 100,000,000 households in the United States. It's a pretty good bet there's at least one refrigerator in each of those households and many of those refrigerators are not full which wastes a significant amount of energy since a full refrigerator runs much more efficiently than an empty one. So how do you keep your refrigerator running at peak efficiency if you don't keep it full of food? Fridge Savers energy absorbing blocks fill the empty spaces in your refrigerator, reducing it's energy usage. A savings of just 10% will save the country at least $1 billion in energy costs and cut CO2 emissions by 1.8 billion pounds.

But, here's a concept board to take to consumers to gauge their interest in the idea (Click on the image to see the concept full size). At a time when people are concerned about the small steps they can take to save money and energy, it might be worth a look.
