**__ Is there a way to use energy from food to power a car? __**
====A system similar to the digestive system in mamals for example. If you consider how much work the human body does (breathing, pumping blood, muscles etc.) with what looks like a very small amount of food for extended periods (many days if need be); this is a very efficient system. Couldn't we replicate this to power our cars with, say, grass? Like a cow. ==== ====We could just use the grass cuttings after we cut our lawns and just "feed" our cars whose "digestive system" could then use the carbohydrates in the grass to produce energy which could then be converted to mechanical energy and drive us around town. ====

Consequences of using fuels energy to power a car.
====First of all most of the energy we use in our vehicles comes from oil. The trouble with fuels is that we are using them much more quickly than we are creating them. Another problem is that burning fossil fuels such as food creates a gas called carbon dioxide that is building up in Earth's atmosphere and causing a problem known as global warming (climate change) which is about the increase of the temperature of the earth. ==== ====One sollution is biodiesel. Biodiesel is made from plants such as sugar. In a sugarcanes you can use the sugar to make biological etanol that can be used to power cars. From 1000 sugarcanes you can make 100 liters of bio-etanol which is equivalent to 66 liters of gasoline. ====

Ammonia
Ammonia can be used as fuel. A small machine can be set up to create the fuel and it is used where it is made. Benefits of ammonia include, no more need for oil wars, zero emissions, and distributed production reducing transport and related pollution.

Ammonia is a compound of hydrogen and nitrogen (NH3). It is a colourless gas, that smells of pungent. It is used in fertilizers, and food.
