So I've already got these huge pumps that collect all of the air "pollution" from factories. They harvest all the gases and compact it into dirigible balloons.
The point of all this is to send CO2 and methane to other planets to begin creating a feasible atmosphere to begin to support low-energy plants, like bamboo.
How would I ship the gases to a nearby planet or system? Would this even work for creating an atmosphere?
EDIT:
My ideas for transportation are an ion particle accelerator like L3 makes. slow, but utterly efficient. I guess the biggest problem is it would be super expensive if I have to send small payloads but I can't quite figure out how to send larger amounts without creating multiple craft for each planetary mass. I need it to work in different situations
