Solar Panels

I worry that the cost of solar panels going down is going to make this stuff even less likely, because it'll be easier and easier for more of us to put solar panels on our house. As battery technology gets better too, i wonder if we'll be less and less inclined to invest tons money and putting the stuff in space. But again, it would be super cool if i was wrong. It would be super cool. And i hope he's right. Who knows which technologyis going to win, but defferently, humanity is going to win, right?
