I took my statement from what was said by the scientists, not for myself. The oil companies would not be interested in nuclear energy, so I am somewhat confused on why you even bring that up. It's not a cover-up, it's just that they're more interested in continuing their currently less-than-environmentally-safe projects than spending a lot of cash setting up a new one. Don't jump to conclusions like that, as you don't really know anything about the subject.
When I said it didn't "wobble", it's of course a matter of definition. Technically, there is no way for you to prove that it does so as mostly everything in astrophysics is theory. For all you know, the universe could have made a tiny little wobbly bit around the sun and given it the illusion of wobbling. The point is, the sun does not "wobble" to the extent that "wobbling" is an appropriate word. Of course it moves, but "wobble" seems inappropriate. "Area of expertise", well, then you should add "astrophysicist" to your occupation, because I was unaware you had a degree in this (since you're an expert, you must have some kind of degree, that is my logic.
I think you are taking things out of context. The sun is not a means for extracting energy, the solar-panels are. They break easily. They are expensive to replace. They have to be replaced something like what, every two years? Three years? Four years? It doesn't really matter. The point is, that in the future, this technology will become lighter and easier to use - and at that point, it will be a likely candidate for backup power in space.
The problem on Earth with solar-power is our pesky atmosphere. It filters out a lot of the energy we could otherwise have gained from the sun. That, and the fact that the solar-panels we're making is currently too expensive to use on a massive scale, and hardly efficient enough to be a good alternative to say, water-power.
