Chocolate-based fuel and plant fiber car - A new wave of eco-friendly innovation


A team of scientists in Britain have harnessed the unlikely fuel source of waste caramel and nougat from chocolate manufacturer Cadbury Schweppes. As part of the experiment, Escherichia coli bacteria were fed the sweet left-overs from the factory. The bacteria then belched out hydrogen gas after a process of sugar fermentation and conversion of formic acid. This surprising source of hydrogen was subsequently used to power a small fan via fuel cell technology. As a highly efficient source of energy, fuel cells have a zero emission rate when used with hydrogen. Continue »
