The AI (人工智能) has changed our lives. There are four useful AI inventions here.

Jiuge

The AI can remember 300,000 Chinese poems clearly. What’s more, it can write a poem in a very short time. In a CCTV show, Jiuge beat three great poem fans from a famous college.

Forpheus

The ping-pong robot can play in an easy way with a beginner and a difficult way with a better player. What’s more, it not only encourages players with words like “Good job!”, but also gives some good advice to improve their skills.

Self-driving AI

It can drive the car more safely than humans. It doesn’t drink wine and never feels tired. It can do what we humans do. For example, if a car with this AI has passed a bus, it will flash (闪) two white lights side to side to show thanks to the bus.

Facial Recognition (人脸识别)

It is used a lot in the world such as ACS. ACS won’t let a stranger in without the house owner’s permission (允许). Paying by facial recognition is common now. The police in Hangzhou even caught a criminal (罪犯) at a concert with its help.

Alfredo Moser is a Brazilian worker who is skilled at repairing machines. His wife says her husband has always been handy at home and made tables and chairs. Alfredo has invented a way of lighting his house during the day without electricity.

He has been using plastic bottles filled up with water and a little bleach(漂白剂) to provide dark rooms with light for many years. And the idea has now spread across the world. It is predicted that his lighting system, which works using refraction(折射) of the sunlight, will be fitted in over a million homes by the end of this year.

Alfredo used normal plastic drinks bottles that are often thrown away. The secret of the water in the bottles is the bleach added to water, which stops it turning green in the sunlight. Mr. Moser drills a hole in a roof tile and then pushes the bottle in from below, keeping the bottle in place with polyester resin (聚酯树脂). Depending on the strength of sunlight, the light fills his home, and the bottles are just like electric bulbs of between 40 and 60 watts.

Alfredo came up with the idea for his “Moser light’’ during one of the blackouts in Brazil in 2002. He said only factories had power in his home city, in southern Brazil during the energy shortage.

The local supermarket and his neighbors’ houses are using Moser lights. He earned a few dollars, but his invention has not made him a rich man. Now a great number of people admire what he is doing!
