How Modern Refrigeration Saved the World
History of refrigeration: how refrigeration saved the world
My Guest Will Pollack
Host: John Dungan
-Persian wind catcher as far back as 5th century but painting show evidence of wind catchers in egypt around 4000 BC
-Persians made Yakhchals to keep ice cold all year making the first known refrigerators
-mid 1700’s William Cullen (https://en.m.wikipedia.org/wiki/William_Cullen) (a Scottsman), Benjamin Franklin (https://en.m.wikipedia.org/wiki/Benjamin_Franklin)and John Hadley (https://en.m.wikipedia.org/wiki/John_Hadley_(chemist))discovered that evaporation took place under low pressure and could cause freezing temperatures.
-Englishman Michael Faraday (https://en.m.wikipedia.org/wiki/Michael_Faraday) in 1820 liquified ammonia by using low and high pressures.
-In 1834, almost 100 years after pressure difference could cause cooling effect the first vapor- compression, enclosed loop, refrigeration system was built by Jacob Perkins.
- Wikipedia “Like many of the medical experts during this time, John Gorrie (https://en.m.wikipedia.org/wiki/John_Gorrie) thought too much exposure to tropical heat led to mental and physical degeneration, as well as the spread of diseases such as malaria.[13] (https://en.m.wikipedia.org/wiki/Refrigeration#cite_note-13) He conceived the idea of using his refrigeration system to cool the air for comfort in homes and hospitals to prevent disease.”
- in 1851 James Harrison (https://en.m.wikipedia.org/wiki/James_Harrison_(engineer)) built the first successful mechanical ice-making machine. He then built through the 1850’s made a series of machines for breweries and meat packing facilities.
-Up to this point harvested Ice from new England area was shipped south to meet the needs of brewing and meat packing. But brewers started to notice tainted ice from pollution and sewage. To answer this problem modern refrigeration was implemented. This was at the same time germ theory was developing.
-towards the end of the 19th century it started to be more accessible and everyone was on the refrigeration invention kick. even Albert Einstein co-filed a patent in 1930 for a refrigerator.
-Study on cause of lessened mortality linked https://childrenshealthdefense.org/news/the-impact-of-vaccines-on-mortality-decline-since-1900-according-to-published-science/ (https://childrenshealthdefense.org/news/the-impact-of-vaccines-on-mortality-decline-since-1900-according-to-published-science/)to refrigeration and sanitation
-on October 19, 1970, Harvard’s Dr. Edward H. Kass (https://www.nytimes.com/1990/01/19/obituaries/edward-h-kass-72-researcher-on-toxic-shock.html) gave a speech “Infectious Disease and Social Change (http://vaccinesafetycommission.org/pdfs/Kass%201971.pdf)” attributing 74% reduction in mortality since 1900? he did say.
A follow up study by McKinlay and McKinlay in 1977 attributed the lessened mortality to “water treatment, food safety, organized solid waste disposal, and public education about hygienic practices.” Also, “improvements in crowding in US cities” played a major role. Clean water. Safe food. Nutrition. Plumbing. Hygiene.”
a big part of this is food safety which is keeping food cool enough and heating it up enough
