Mist Creates an Oasis in the City
Against the Heat Island Effect
Bettertopia resident and her daughter
Mom, come this way! It’s nice. Let’s wait here for our bus. Wow, it’s hot again today. It feels like the temperature just keeps rising every year. Don’t you feel that way? The whole world has been suffering from extreme weather. What is happening to our planet? By the way, do you know anything about this comfortable space, Mom? This is called Green Air-Conditioner by Panasonic. They say it’s a new Urban Oasis. It’s an air conditioning system for outdoor public spaces, like this bus stop, parks, and leisure facilities.
You might think it’s a complete waste of energy to even try to air condition outdoor spaces, but it’s reducing waste by using an air curtain that controls air flow in the space to keep the cool air in a certain area. The droplets of water in the mist coming from here are only 10 microns in diameter. It’s made of water, but they are ultra small particles, so the mist doesn’t even feel wet. Even so, it can absorb heat from the air and from your skin as it evaporates.
What? It reminds you of the traditional Japanese summer ritual to spray water outside? Good point, Mom. The Japanese custom to spray water on the ground while the sun is not high up must be an old wisdom to keep cool in the hot summer. This Green Air-Conditioner has the same idea to utilize the effects of evaporating heat. That’s a real example of Cool Japan, which is a campaign that Japan has been doing to promote tourism. Oh, our bus is coming. I don’t want to leave this oasis but we really should go now.
