Biofuels
jet engines require air, compression, and combustion to make it work
source:(http://en.wikipedia.org/wiki/Biofuel)we use biofuels because they do not make as much pollution as normal fuels.
The pistons of a bus move to make the wheels move.
One common aspect of biofuels is that they are derived from renewable biological materials, such as plants, agricultural residues, and waste. This allows them to be produced sustainably, reducing reliance on fossil fuels and lowering greenhouse gas emissions. Additionally, biofuels can be used in existing internal combustion engines and infrastructure, making them a practical alternative energy source.
In order to grow the crops required to produce biofuels more forests need to be knocked down to make the necessary fields.
The same way fossil fuels power work. They are just produced in a different way.
SG Biofuels was created in 2007.
by mechanical force Presumably with renewable resources, such as biofuels, wood etc. Obviously it depends on the type of engine.
Biofuels produce energy by converting organic materials, such as plant matter or animal waste, into usable fuel through processes like fermentation or transesterification. When burned, these biofuels release stored chemical energy in the form of heat, which can be used to generate electricity or power engines. The combustion of biofuels results in lower net carbon emissions compared to fossil fuels, as the carbon dioxide released during combustion is offset by the carbon dioxide absorbed by the plants during their growth.
Yes, soybean oil is the main source of biodiesel.
