Wooo, this is damn suprising me ! So, don't talk much, let's see read THIS !
1. The first air conditioner wasn't for people's comfort.
The first modern air conditioner was invented by Willis Carrier in 1902 for a publishing company in Brooklyn. The machine kept temperature and humidity low so that paper didn’t expand and contract. Carrier never intended for his invention to be used solely for comfort.
2. AC is why we enjoy summer blockbusters.
Theaters jumped on the AC bandwagon early, even in the midst of the Depression. They were among the first places where most people encountered artificially cooled air, and in the hot summer months, movie houses were often the coolest places in town. When the weather got stifling, people cooled off by flocking to see films. Expecting big movie-going crowds, the studios began releasing their best and most lavish productions in the summer, giving birth to the modern summer blockbuster.
3. Before AC, everyone got summer vacation.
Before AC, most industry traditionally slowed or stopped in the summer, when buildings were hot and workers were sluggish. Back then, many American workers got month-long August vacations similar to what workers still get in Europe, where AC isn’t as popular. Even the government tended to shut down during parts of the summer. Some historians blame the growth of federal bureaucracy on air-conditioning, since it enabled lawmakers to stay in session longer.
4. The development of effective temperature control and refrigeration has revolutionized almost every aspect of industry.
Without AC, the following things would be virtually impossible: the manufacture of computers and chipsets; data storage centers; the production, delivery, and storage of food; pharmaceutical manufacturing; and chemical manufacturing.
5. Climate control has completely changed the way we design and construct buildings and homes.
Gone are the cool brick structures with high ceilings, transoms, breezeways, strategically placed shrubbery, and sleeping porches, all of which were designed to keep inhabitants cool. Today’s glass skyscrapers and low-slung tract housing don’t have the same ventilating and heat-defeating features, so going without AC today feels more unbearable than it used to.
6. It's even helped us live longer.
AC allowed for exponential advances in medicine and human life expectancy. Air-conditioned hospitals helped defeat malaria, decrease infant mortality, inhibit bacteria, and advance developments in surgery.
7. It changed where Americans choose to live
Before AC, the Northeast was the economic powerhouse of the United States. Since 1960, 60 percent of all the economic growth in the country has taken place in the South, where AC made year-round factory work and apartment-living possible. Demographers agree that the population explosions in places like Arizona, Las Vegas, Florida, and Texas can be directly attributed to air-conditioning.
8. Air-conditioning conditions us to want more air-conditioning.
There’s scientific evidence showing that spending too much time in cool environments erodes humans’ natural tolerance for heat.
9. The amount of energy the United States uses every year to power our air conditioners is about the same amount of energy consumed by the entire continent of Africa.
Despite much technological advancement, air-conditioning units still consume massive amounts of energy; NPR notes that the Department of Defense spends $20 billion per year on air-conditioning in Iraq, more than the total yearly budget for NASA.
