Elon's Hyperloop idea is not in the same category as Tesla, SpaceX, and SolarCity. I think it is mostly his mind dealing with the problem of California wanting to spend an enormous amount of money on something that Elon sees as being outdated technology. Tesla, SpaceX, and SolarCity are about changing the world. I think that is why he is going to giving the idea to world and letting the world see what they can do with it. At some point he might put some money into the idea but, in my opinion, I don't see this as being a priority.
If it is successfully realized in California, it could potentially spread across the globe and turn into a revolution of public transportation.
