Light from Leftovers?

This is some exciting news. British researchers have developed a cheap, efficient microbial fuell cell (MFC) which runs off of organic waste. It uses e.coli bacteria to generate hydrogen from carbohydrates. Waste products are not a concern here because the raw materials would have gone into the trash to begin with.

50 grams of sugar can light a 40 watt bulb for eight hours. With three children and four adults in our household, we generate enough carbo waste to light up the whole block.
