In the interim, prior to 25 - 30 years, it seems to me that there is a good chance we might see distributed AC spread across the landscape as small substations spring up at local "filling" stations - which use to dispense gas but will soon "fill" the high efficiency batteries of electric cars. I'm thinking of something similar to the internet where small distributed sub-generation stations constantly replenish the electrical grid. Computers will constantly monitor the grid making sure power is evenly distributed among all the "cells". In my view, the beauty of such an interim solution would be that jihadists and other idiots will be deprived the satisfaction of blowing up power plants and as such deprive hundreds and thousands of businesses and home owners of AC. If one or two sub stations are taken out nearby substations ought to be able to take up the slack easily. Eventually, however, most devices and appliances will be manufactured with their own CF generators. No more plug'n'play! Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
