The house of the Microsoft founder is evaluated to cost about $150 million. And it’s the true embodiment of the cutting edge technologies (which is not surprising). And this ‘smart’ home is fullly operated by Windows system. The guests of Gates are offer to take a personal device which reads the temperature, blood pressure and transfer the data to the main server, where it’s being analyzed. At the result the system send commands: to make lights darker or brighter in a particular room, fade the music, adjust the room temperature. There is a huge library with a clear dome instead of the ceilling. There is a private cinema, yacht piers. Periodically Bill Gates puts on charity auction a right to visit his house and have a dinner together. In 2008 this lot was sold for $16000 and a year after for $35000.
