Up vote for having watched Seba's latest series. I think I rewatched 6 times over the weekend (road trip in sunny Australia). Heh.

I suspect that this example was hyperbole on Seba's part, as the retail cost of structural plywood is still a hell of a lot cheaper than solar panels in AU, and I don't think they have the same structural qualities.

However, the point that they can be used as a substitute for exterior wall flashing, even if the primary purpose of producing electricity is significantly reduced by not being positioned for maximum efficiency, was not lost on me.

I wonder what purposes they'll serve at the end of the decade when they have reduced in cost by another 75%, and the 'possibility space' continues to open...
