Twenty billion dollars to develop and demonstrate a reusable mass-driver system for deployment unmanned cargo to orbit? In the big scheme of things it's a drop in the bucket. But it would make a ton of other things much, much cheaper.

The only problem is that it doesn't sound as sexy as a "vision" of space exploration decades from now.

And with little sticking, IMO. At least in the positive sense.

Of the words that history may eventually use to describe the guy, "leadership" will likely not be one of them.
