We Predict Solar Future by Andy Lee Graham World Traveler
Your thoughts and knowledge about solar agree with what I have read and assimilated over the years. I took classes in solar "science" and installations in the mid 80's when the industry was just starting. Installations were more a hobby for the well to do for the next 2 decades. Free or cheap energy IS the next revolution. It would also enable the desalination of water before clean water becomes the next oil.
We could also speculate about Nikola Tesla having been "on to it" (albeit a different source of free energy) before his death and the subsequent confiscation of all his work by the government.
