Maybe in Mexico. I have a home in Palm Springs, CA. It's easy to keep the interior at 74 degrees when it is 115 outside with a normal air conditioner. And it takes my car and SUV only a couple of minutes to go from blister your hands hot to cold enough to hang meat.
The key on the home is to not let the temperature rise significantly. I have low E windows and keep the shades partially drawn. I keep the thermostat constant so the system only has to hold the current temperature, not cool the house down during the heat of the day.
The only evaporative cooling you see anywhere is on golf carts, patios and other outdoor areas. Misting systems are common in these uses. As for swamp coolers, you only see them in warehouses, auto garages and other poorly insulated structures that are need to be open to the outside as a course of business.
