There would be no more awesome way to travel (except, maybe flying) than getting from A to B via a BOOM tube. Another Jack Kirby concept, BOOM tubes open up a stable wormhole from one place to another and allow people to walk through. BOOM-ing is the only way to reach the New God homeworlds of New Genesis and Apokolips, as well. According to New Gods Issue 1 (1971) a BOOM tube stems from the waves of the mind - which makes sense, as they both appear and disappear into thin air, once all parties have exited the tube safely. They are usually controlled by Mother Boxes (more on those later). There appears to be no carbon emission to worry about (unless you count the residual Kirby crackle, of course) and no mess either. Plus, as a storytelling device, it enables characters to travel from place to place with only minimal interruption to the narrative. In more recent DC comic books, Justice League member Cyborg discovered that he could replicate the BOOM tube technology and now The League use it to get from place to place on Earth. It would certainly cut down the cost of this years holiday!
