For the record Henry Ford's business model was based on a car being affordable to the masses and that was in the infancy of the automobile and hardly "generations ago".  What's also not mentioned is inconvenient truths such as the lifespan of solar panels or wind turbines.  Not exactly forever and in harsh environments (i.e arctic / desert / marine) even less.  Consider too how fuel cells were all the rage 10 years ago and by now should be powering everything from vacuum cleaners to aircraft.  Glad not to have bought stock in that industry.
