Chinese technology brand Lenovo has revealed a prototype of what it's calling the "world's first ultraslim solar-powered PC", which looks like a regular laptop but runs on energy from the sun.

But the new concepts are all about adding more displays. There's the Magic Bay Dual Display Concept, which adds two 13.3-inch 2.8K 120-Hz LCD screens flanking around your ThinkBook's primary screen.

That’s the promise of Lenovo’s latest concept laptop, a Yoga model featuring a photovoltaic solar panel on the rear of the screen, converting light into charge for the laptop’s battery.
