Scientists believe that the smart home may be the home of the future. These homes may be of different shapes and sizes. They may also float on the water.

Scientists have designed the eco houseboat - a kind of house floating on the sea. But the houseboat is stable and doesn't rock heavily when there are big waves. It makes use of waves and solar energy to move it around and provide power. It also has solar panels on the top of the house to generate electricity. And it can recycle all kinds of household waste. 

A robot controls everything in the house and does the housework. In the kitchen, smart refrigerators and dishwashers can automatically work by themselves. A smart oven can cook your favourite dishes. All these things and other advances will make our life much better.
