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.
