Question

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Engineers believe that they are all possible. The only thing for sure is that the houses will be greener than today.

The tree house

Many engineers in the world would like to build a "tree house." Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat (加熱)water, produce electricity for the lights, and even create fresh（新鮮的）air for the home.

The Lizard（蜥蜴）house

Like a lizard, changing color with the weather is the most important design（設(shè)計）of a lizard house. When it's in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.

Meals at home

It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.

Learning from the past

Looking to the future isn't the only way to be green. Sometimes, the old style of building can also help cut down energy use. For example, a chimney（煙囪）can be a useful air conditioner because it is easier for hot air to flow out through the chimney.
