Km, thanks for the perovskite tip earlier, I read some more by Will Lockett, it looks like he might be at last coming around to solar, as a result of the new longevity research. Why not write some stories with more of your own thoughts? I for one would be interested to hear more, I suspect we might have similar views of things, but even if we don't, all views are valid. We are on a path of learning, I don't believe any one of us has it all sussed out yet, but I do believe between us all we will thrash it out. No problem can withstand the power of billions of brains and twice as many eyes, it seems to me... :)
