The efficacy of bioethanol fuelFeatured science projectScience project video


The hypothesis that bioethanol has a lower energy density than gasoline, and therefore will cause a smaller increase in water temperature when burned, has been proven to be true.

The rising price of oil has increased the demand for biofuel as an alternative fuel. In 2008, about 1.8% of fuel used in transportation was sourced from biofuel. However, the increasing production of biofuel has raised concerns regarding the rising price of animal feed and livestock.

The experiment may be repeated by using different types of biofuel, such as biodiesel.
