But the most exciting item was a variant of a SURGE drive that could be used on large bodies. Like asteroids. Or Kuiper objects. Epsilon Eridani 2 needed about five or six hundred cubic kilometers of ice dropped on it, in order to connect the seas into oceans. I’d been mulling over how to get those Kuiper objects into the inner system. Hohmann orbits would take decades to centuries. That wasn’t necessarily a problem for me, but for humans needing a place to live, a little more alacrity might be in order.
