Gasoline also comes from corn or anything else that can be distilled to ethanol. For greater calorific efficiency we should be looking to biodiesel as the environmental side effects are as minimal, you get more miles per gallon (km per liter), and the production of biodiesel via algae can happen efficiently in places not currently used for livestock grazing or growing crops.
