Miele's latest dryer utilizes heat gathered by rooftop solar-thermal collectors
At last year's IFA electronics trade show, Miele unveiled its SmartGrid-ready washer and dryer. Although they run off of regular mains power, these machines are also able to access the internet and determine when rates will be cheapest. Users indicate the time period in which the laundry must be washed or dried, the appliances choose the least expensive time within that period, then proceed to automatically start at that time. At IFA 2011, Miele has gone one better by unveiling what it describes as the world's first dryer to use the heat of the sun to get the wetness out of clothes.
