Outdoor drying (sometimes called air-drying) with a clothes line or rotary dryer has several big advantages: it's free, it uses no energy (so it's environmentally friendly), it generally leaves your clothes smelling fresh, and it means you don't make your home damp and cold by drying things inside. The drawbacks include the time taken to dry things (which can range from a few hours to a day or more), the chance of rain making your clothes wetter than they were when you hung them out, the risk of theft, and the possibility of air pollution making your clothes dirty again.Producing steam from water requires a huge amount of energy, known as the latent heat of vaporization (you can read more about this in our article on states of matter).
