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

The tree house

Many architects 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 water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.

The Lizard house

Like a lizard (蜥蜴), changing color with the weather is the most important design 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

This design is perhaps as much about the future of food production as architecture (建筑风格). 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, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.

A 22-year-old British student has invented(发明) a mobile fridge, “Isobar”, which could save millions of lives in the world.

Will Broadway’s “Isobar” has been designed to k【1】 vaccines (疫苗) at the ideal temperature while they are being sent in developing countries. And Will doesn’t plan to make money from his creation. His p【2】 is to get vaccines to people who need them, which is why he won’t be trying to get a patent(专利). Will’s Isobar has w【3】 him the James Dyson Award that challenges young people to design something that solves a problem.

Present methods of transporting vaccines can l【4】to the vaccines freezing(冻住) before reaching their places in developing countries, b【5】 the Isobar keeps a temperature of 2 to 8 degrees for 30 days.

Will’s invention is expected to save the lives of 1.5 million people a【6】 the world. After finishing college education, he is making an effort to take the Isobar into production. “I will be hands-on, all the way through it, and m【7】 sure that it works, ” he says.

The product has been designed to transport vaccines, but already Will sees the possibility for other m【8】 uses in the developing world and beyond. “Blood donations, organ transplants(器官移植) —if they get trapped in t【9】, you still use cold-bags that really aren’t good enough for a long time, ” he says.

There is also a possible, non-medical use for the Isobar. “It would be a great thing to take on a five-day trip w【10】 you have no power,” he says. But he insists vaccine transportation is the primary function (功能) of his invention.
