"For those of us who live in the sweatier parts of the country, life without air conditioning can be difficult to imagine. Not even the opportunity to pop into a chilly movie on a sweltering day?

"When air-conditioning was first invented, hardly anyone wanted it"

But when air conditioning was first invented in the 1800s, hardly anyone actually wanted it. It took more than 100 years for AC to really catch on. This innovation took a long road, which Salvatore Basile explores in his new book, Cool: How Air Conditioning Changed Everything.

"I think there were many people who thought, 'God made bad weather so you should just put up with it.' And I think the idea of dealing with heat was to ignore it," Basile told me in a recent phone interview.

Eventually, air conditioning did win out and ended up changing a lot — from where people live in the United States to the architecture of our buildings to even the evolution of computers. The interview with Basile is below:

Susannah Locke: Many people know that Thomas Edison invented the lightbulb. But who invented air conditioning? This person never seemed to get that level of fame.

Salvatore Basile: The key person is John Gorrie, who in the 1840s put some ideas together. He was sort of an amateur tinkerer and developed the first refrigeration compressor. It was something driven by a steam engine. He could make cold air. He could also make ice.

""the machine pretty much fell into oblivion""

He was a doctor who worked in Florida, treated a lot of fever patients, and thought that if you could bring their temperature down, they might be cured. That is how he became interested in this machine. It worked in his hospital. But when he tried to patent it, he ran into opposition — this is sort of the legend — from the natural-ice trade at the time. Artificial ice would have ruined their business. He was never able to get his machine into production, and the machine pretty much fell into oblivion.

Then it was years later that Willis Carrier developed what we all know as the first real air-conditioning system. But it was a very expensive job no matter where it was done, so it was done exclusively in factories. Carrier tried for years to sell this to the home market. But unfortunately at the time when the technology was becoming small enough to be inserted in a house, the depression hit. And people who could not afford bread were not about to worry about their summertime comfort. And once the country recovered from the depression, we were in the middle of World War II. So it wasn't really until after the second World War that the United States consumers had a chance to look at air conditioning as a possible, real, viable alternative.

SL: There seemed to be a ton of resistance to the idea of air conditioning. People weren't even interested in the idea of getting cooler air. Why was that?

SB: The US is a puritan country. And because we're a puritan country, I found that there were people who would quote the book of Amos from the Bible as the reason — that the Lord was the being who created the wind. In other words, man was not to do this. So fans were inherently sinful. This, I think, carried on to the idea of any machine that would change the weather, even though heat was something that we'd been doing for millennia.

"PEOPLE OBJECTED TO IT FROM A MORAL STANDPOINT"

The idea of cooling your own air, I have a feeling, to many people that felt very self-indulgent at the time. I think they objected to that from a moral standpoint. So the idea that human comfort would be mixed up with morals, well that's sort of a bad place for the PR of air conditioning to exist. And when we got into the idea of having a machine that could actually cool the air (and the first examples of that were in the 19th century), there was one man who was ousted from his church because he had seen such a machine. And it was powered by a steam engine, and his church committee had accused him of lying because such a thing could not exist. It was against nature.

So transferring that into the modern time, I think there were many people who thought "God made bad weather so you should just put up with it." And I think the idea of dealing with heat was to ignore it. Indeed, in Victorian society, one must ignore hot weather because it did not exist. That was simply the given standard of behavior for the time. And so many people would ignore it and then keel over from heat stroke.

With that kind of mindset in the population, to offer them the chance to be cool did create a lot of opposition at first.

SL: For a long time, extreme cold was viewed as unhealthy, but extreme heat was viewed as an annoyance. What was medicine's view of why people felt bad in stuffy, crowded rooms?

SB: Doctors did not have a standardized way of dealing with heat exhaustion, heat stroke or even a standardized way of viewing it. In a confined space, which theaters were the worst because they had no windows, basically the idea was that something called crowd poison would spring up out of nowhere from the exhalations of people.

"SOME doctors recommended drinkING as little as possible ON A hot day"

And the medical establishment at the time was so divided and so opinionated and in many cases so unscientific that there were doctors who recommended you drink as little as possible in order to get through a hot day. If someone were to collapse on the street of heat exhaustion, I found that they might be injected with brandy or given a turpentine enema or rubbed all over with mustard. And it was only a few doctors who thought, "Cool the patient down," and very few thought to hydrate the person. And as far as the consequences, every day in the papers you would have a list of people who had died from the heat, and depending on the day it would be sometimes a very long list, unfortunately.

SL: One of the things that was making people so hot was that buildings weren't designed with ventilation — moving the air around — in mind. What were some of the terrible designs that made people swelter?

SB: Of course, part of the biggest problem was that glass in the 19th century was very expensive no matter how you got it. So windows were at a great premium. Because of that, many buildings ended up having very little in the way of openings to the outside air.

And, of course, with the stone and brick construction, buildings like that might be somewhat insulated from heat, but when they got hot they stayed hot longer.
""air conditioning was responsible for an entirely new type of architecture""

When skyscraper architecture began to exist, the theory was that space was not really rentable if it was more than 25 feet from an open window because there would be no way to get air into the building. In New York, if you look at many of the great towers, the Chrysler Building, the Empire State building, absolutely they had been built very carefully to makes sure that they would be very open to windows, if possible.

It was not until the advent of air conditioning that the actual climate inside could be changed. By the 1950s, buildings were being built that had no windows operating at all. In that sense, air conditioning was responsible for an entirely new type of architecture.

For that matter, computers would not really have existed without air conditioning because the thousands of tubes that computers used in the 1940s and 1950s. They had to be in refrigerated rooms, basically, in order to not burn up.

SL: Air conditioning is a huge energy consumer, and energy use is becoming more and more of an issue. What do you think is the way out?

SB: That is a problem. I have learned that there's research happening now for systems that will be entirely different from the current version of air conditioning that we all know and love. There are machines that will take the place of the compressor-driven air conditioner.

""energy efficiency - yes, that is a problem, however it is also a problem to die of heat exhaustion""

There is research being done on something called a DEVAP, which is pretty much a refinement of what used to be called the swamp cooler, the evaporative cooler. (Evaporative cooling is the old system where air would be blown through a moistened filter.) It is enabling air to be cooled without using refrigerants. Now, if this is able to come into the marketplace, you'll be looking at a machine that could cool air for possibly an energy savings of up to 90 percent. That is great. This would work in a very low humidity environment.

And then manufacturers of standard air conditioning as we all know it have been working for some years to make those machines much more energy efficient and with refrigerants that would be much more powerful. As far as the energy efficiency — yes, that is a problem by all means, however it is also a problem to die of heat exhaustion.

SL: At what temperature do you keep your air conditioner?

SB: I tend to keep mine at 73. I've tried 74, really I have. I'll try to do better in the future, I promise.

Given the data from Pecan Street, if we can get 25% of American homes to use these types of IP addressable Thermostats, we can greatly increase the amount of solar/wind that can be added to the grid without mandatory battery storage.

"Last October, Jon Wheatley, an Airbnb host who made $13,608 in yearly profit, wrote a piece on the website NeedWant explaining why the device can be helpful to those renting out their apartments or homes to strangers.

"Nest has a great 'auto away' feature that activates when nobody walks past it in a predetermined amount of time. This turns off all heating and cooling when nobody is in the unit and you and your guests don’t need to think or worry about it. The cost of a Nest probably pays for itself in a couple of months with this feature alone. This also lets you login to your Nest account and see if a guest has arrived safely or not without having to bother them," he wrote.

Others have piled on, calling the Nest a "must-have" for people listing their dwellings.

"A quick search of the site shows many Airbnb listings with Nests. As homes evolve to be aware of and responsive to us, they know we’re there. And anyone with access to their data streams knows we’re there too," wrote Forbes' Kashmir Hill, describing the allure of the device beyond energy.

Presumably Nest, sensitive to the speculation about privacy and its relationship with Google, is not going to pitch its devices as a way to monitor a home. But it's a nice perk for hosts.

In July, Nest bought the home video monitoring company Dropcam for $555 million. One could imagine Airbnb hosts using the cameras in select outside locations (doing so inside would be illegal without notification, not to mention creepy) to see when guests arrive and leave. It's important to note that Nest is not talking about Dropcam in this context, but it's possible to see how other products could fit into the picture.

Nest is also providing the Airbnb hosts with free access to MyEnergy, the energy monitoring service it acquired in May of last year to get deeper into home performance. Bringing thousands more customers onto the platform is a great way for Nest to gather more information on how people are using the devices and saving energy, while potentially pitching more services like residential demand response as the company expands utility partnerships.

Finally, Airbnb has clocked more than 10 million guests since it was founded. If Nest can get its sleek product in thousands of rental units where tens of thousands more people are likely to see it, that's an invaluable branding opportunity.

The alliance between Airbnb and Nest is certainly about making the "sharing economy" more efficient. But Nest has landed a very important deal that has much more value than helping people save a bit of money on their energy bills.
