Hydrogen Trawl

The hydrogen trawl is a standard piece of equipment found on most deep-spacefaring vessels.The trawl is essentially a muon field which forms a large net-like structure trailing after the ship, allowing for the capture of free hydrogen gas for use as fuel in the onboard hydrogen fusion reactor. This technique all but guarantees that the ship will never run out of fuel, but trawled hydrogen is typically impure and of lesser quality than the refined product offered by the hydrogen industry.
