One thought on “A Picture Of Progress”

  1. Dave says:

    J., I once read in an old library book about two gents in California in the 30’s who provided solar power for all the homes in their little valley with what looked like an old steam engine, a closed system actually with a liquid or gas that boils at a very low temp to create the steam. The liquid was heated by solar collectors. I have looked everywhere for any reference to this and have come up empty. This would look like progress to me if it were true. Ever heard of it?
