Editing Compressed-air car (section)

==Emissions==
Compressed air cars are emission free. They also do not require a connection to the electric grid. A [[wind turbine]] or other [[renewable energy]] source can directly drive an [[air compressor]] or [[hydraulic pump]]. Compressed air cars do not rely on [[petrol stations]] or an [[electric grid]]. While centralized infrastructure might not be needed, it is an option. Tankage can be directly shipped, or a pipeline can be utilized.Compressed air is normally filtered to protect the compressor machinery. Therefore, discharge air has very little suspended dust. There may be some lubricants emitted by some systems, but further development might reduce this with oil free compressors and intercoolers
