A lot of hype on this engine.
Yes, there have been a few posts here (by me) about it. The claims are pretty extraordinary though. The current crop of ion engines are already 10 times more efficient than chemical rockets. The claims for this one would mean we have a real deep space tool. Of course, they've got to scale this thing up and eventually get in space. I guess we'll know in ten years time if it meets all the hype.
