Kenya Hara’s zero-energy humidifier consists of water resistant paper which make droplets evaporating from the paper. A coating of hydrophobic aerosol makes the droplets bead up into balls. The surface of the coating is similar to the surface of the lotus leaf, which has a specific texture that causes the water into round droplets. These drops evaporate more quickly than spread water, therefor making the humidifier effective without heating. The coating is developed by NTT Advanced Technology Corporation.
