At first sight it’s a nondescript—if a little futuristic—cube, but appearances, as they say, can be deceptive. And so, this isn’t just any cube, it’s the world’s first personal air conditioner, and it’s called Evapolar. Measuring 17 cm on each side, it can be placed on a flat surface, cooling your immediate environment. It goes a step further to purify and humidify the space at the same time. Unlike traditional air conditioners that use mildly-toxic refrigerant gases (e.g., Freon) to create a strong flow of cold dry air, Evapolar employs just plain water and the ecologically sound, paper-thin evaporative materials, emulating a natural air cooling process. The unit features a detachable 750 ml water tank (which needs to be refilled every 6-8 hours), and it plugs into a regular power grid or power bank via USB, for convenient portability. It cools down a area of of 4 m² with a max temperature decrease of 15 °C. Oh, and lest we forget: unlike your regular AC, it consumes only 10W, so you can be smug in your environment-saving luxury. And it’s yours for $180.
