1 . Here’re some of the excellent inventions in 2023. Which one do you like most?

Whiter Paint

The paint on a white building reflects 80 to 90% of the sunlight that strikes it. The rest of the light warms the surrounding area, raising air-conditioning bills. But the Whiter Paint is made of chemicals that better reflect UV rays. It reflects up to 98% of the sunlight, which could reduce AC use by 40%. “The heat is reflected into deep space,” says Xiulin Ruan, who led the Purdue University team that created the paint.

Duolingo app

Now you can take music lessons on a smartphone, using this app, which uses an on-screen piano to teach basics such as harmony and beat. You learn by interacting with more than 200 popular pieces of music. Just match sounds to notes and play along. “You don’t need natural talent to learn music,” says Karen Chow, who’s a learning scientist at Duolingo.

Model A

Model A, developed by Alef Aeronautics, is a two-seat all-electric vehicle with a flight range of 110 miles. And it looks as if it were made to be parked in a garage. In July, 2023, the Federal Aviation Administration gave Ale f permission to take the vehicle on test flights. The company hopes to deliver the first Model A by 2026.

Moonwalkers

They’re actually battery-powered shoes with wheels. They let you walk normally—just faster and more easily. Moonwalkers, made by Shift Robotics, use AI to sense when you’re speeding up or slowing down, and adjust themselves accordingly. With it, you can walk at speeds up to seven miles per hour.
