Could tear-off screens catch on?

This week's Question: While LG and Samsung have worked to develop screens that roll and bend, a new patent from Google describes a screen that can be torn like a piece of paper. Images in the filing show an advertisement with coupons that can be pulled off and used in-store, as well as a drawing of a robot that has been ripped in half. Additionally, the detached portions are shown being reattached. Disposable displays will likely not emerge as a viable technology until manufacturing costs drop significantly. Engineers, however, have also been working on ways to make digital pixels appear on regular paper. What do you think? Could tear-off screens catch on?

Could a solar-powered airplane be commercially viable?

This week's Question: Solar Impulse 2, a solar-powered airplane, completed a risky, 62-hour flight across a wide expanse of the Pacific Ocean. According to pilot and Swiss engineer Andre Borschberg, the plane now has the ability, in theory, to fly for an unlimited period, with only the human factor limiting how long the plane could potentially stay on the air. What do you think? Could a solar-powered airplane be commercially viable?

Device Allows Paralyzed Man to Perform Complex Movements

Six years ago, he was paralyzed in a diving accident. Today, he participates in clinical sessions during which he can grasp and swipe a credit card or play a guitar video game with his own fingers and hand. These complex functional movements are driven by his own thoughts and a prototype medical system.
