Question

A great invention! 英语作文

Answer 1

I have a good idea. Maybe it could help the people who need water. It’s a machine which produces water from air. So I call it “AW Machine”. It’s my first invention.There is little water in desert, so people can’t live in there for a long time. If people have this machine, they could produce water by themselves. I put a huge folding photovoltaic cell on it, it can provide plenty power for my AW Machine.There is a refrigerator on it top. The wet air enters the refrigerator from air intakes. The vapor in the wet air will be condensed and flow to a container bottom. The machine also can boil the water, so you could drink the water confidently.This is my invention. Do you like it?
