It might seem like a space-age fantasy, but there will be a lot of a serious talk in Seattle this weekend about a “space elevator.”
You might think of it as a space railroad. In theory, the technology could make going into orbit as cheap and easy as buying a first-class airline ticket.
The idea calls for a cable that stretches from a spot on the equator out to an anchor orbiting thousands of miles in space. On that cable, a remote-controlled cabin or elevator zips up and down.
