A waterless washing machine that removes stains from garments in a few minutes has been developed at the National University of Singapore, the facility said on Wednesday. The appliance uses negative ions, compressed air and deodorants to clean clothes. Industrial design students Wendy Chua, 21, and Gabriel Tan, 23, said they were inspired by the technology in air purifiers, which uses negative ions to clump dirt and bacteria, making it easier for the particles to be sucked out. The ions are a natural cleaning agent. More info here.
