Black Swan Technology

A few hours later, I got a call from a gentleman who had seen that I had registered for the Utility Scale Solar show, and wanted my opinion on it.
Immediately, I placed a called to one of my most senior associates in solar technolgies, consulting physicist Bruce Allen, who spends a great deal of life studying stuff like this. He says that this idea, still obviously in the R&D stage, has potential, but that it’s at least a decade from commerical application.
Of course, that’s only one man’s opinion. I’m wondering if anyone else would like to share a viewpoint on this fascinating and important topic.

I’ve asked various people about the feasibility of installing solar panels on roofs of houses by the electric utilities. No one has answered me so far. It seems a waste of resources to use a lot of open land just for the installation of fields of solar panels. Surely there are a lot of houses and buildings in sunny places whose roofs could be available for this purpose.
