My guess? It's a variation on a displacement engine/neural interface device that lets John use Moya as a displacement engine when creating wormholes. I think (pure speculation) that use of this device is harmful to him and that's what he and Aeryn are discussing when she says, "You do what you HAVE to do." And I also think this may be what he uses to destroy that dreadnought in the picture above.
I agree. It MUST be a displacement engine to convert Moya into a wormhole-starter. And I believe it's harmful for John, however, here's an added twist, he uses it, gets injured, Aeryn becomes emotional, but then Einstein comes to the rescue. He (Einstein) either retains or removes the wormhole tech from Crichton (as gratitude for not letting it fall to any alien beings), and at the same time, saving his life. Now that's the other angle.
