ooookay.....

given the suns temperatures I'm pretty certain there is absolutely zero way that anything could remain solid. Remember we are talking fusion temperatures here, the whole problem with fusion as an energy source is that you can't use a "solid" container because there isn't anything that stays solid at those temperatures, so you need a magnetic bottle, which a) leaks and b) requires more energy put in than you actually get out of the reaction.

So no I don't reckon that's possible.
