'HISTOVATION' the Book moves forward

Exciting news - I am in the process of developing a title for an NYC based publisher for a book about 'obsolete' technologies that could have renewed relevance today: From Window Shutters for reducing energy costs to modern hang-dry clothing lines and lenses and fiberoptic for introducing day light into buildings there are numerous examples. Even technologies like electric trolleys and even bicycles are undergoing a renaissance in American cities in particular. What other older technologies might be reevaluated and redeployed in todays digital empire?
