#13 refrigeration! Slow week out there or the answer was too easy. Thanks for responding - Elaine, Mike, Peyton, and Joani!
"No Escape Hatch!"
Secured hatches were all over the Boston Waterworks Museum. I especially liked this one because of the red against that light gray. The peeling paint around the hatch as well as that situation on the red cover was an added bonus. Trying to keep it simple, I simply filled the frame with it!
Greatest Inventions of All Time!
Recently I came across an article about the greatest inventions as determined by a large group of scientists, philosophers, educators, and other professions. Their task was to create a list of "the Greatest Inventions of All Time." Conveniently, the final list numbered fifty! so, I'm starting with #50 and working my way down to Numero Uno in December.
Fear not as I will offer you some hints as to what the invention was.
A major reason we live 40 years longer than we did in 1880!
Major human settlements could initially develop only where fresh surface water was plentiful, such as near rivers or natural springs. Throughout history people have devised systems to get water into their communities and households, and to dispose (and later also treat) wastewater. The focus of #12 at that time was on conveying this disposal to a natural body of water where it would be diluted and dissipated.
In ancient Rome this was quite extensive. These systems consisted of stone and wooden drains to collect and remove wastewater from populated areas. It is estimated that the first devices of ancient Rome were built between 800 and 735 BCE.
There is little record of other systems in most of Europe until the High Middle Ages. Unsanitary conditions and overcrowding were widespread throughout Europe and Asia at this time. This resulted in pandemics such as the Black Death (1347-1351), which killed tens of millions of people. Very high infant and child mortality prevailed in Europe throughout medieval times, due partly to deficiencies in setting up #12.
