I've mentioned the Home Project before. This is another one of their bright ideas. This is what is said about this particular project on Inhabitat, (a good site to check out, by the way!):
"European design duo Kathi Stertzig and Albio Nascimento of the Home Project have made a career out of playing with familiar objects and using them in unexpected new ways. Their MAX 5000W installation is a great example of their environmentally provocative thinking. Asking “What is the value of energy?” and “Is electricity really necessary for light?” this clever candle holder made from an old extension cord plays with the boundaries of high-tech and low-tech."
