Silicon may be at the heart of most gadgets, but it’s not the only semiconductor around.

Gallium nitride has been getting a lot of attention recently for it’s electrical properties, which outperform silicon in a lot of areas.

Gallium nitride has the potential to revolution power systems, including solar, electric vehicles, and even phone chargers.

Beyond that, it’s finding uses in the mobile industry, and could even be used to build ultra fast processors.

But how feasible is any of that, and even if it’s possible, how long will it take? 

2020 is the year 5G will finally arrive for some, but will it live up to the hype?

Part of the problem is that 5G isn’t one thing, it’s a collection of different technologies, and various cell providers are focusing on different improvements that can radically change the experience of 5G.

Engadget has a first look at Samsung’s robot chef.

Normally when I miss breakfast, it’s by choice. Today, it was because I was in a rush to get to Samsung’s booth on the CES show floor and see if I could get any face time with the company’s cute new rolling robot. (That, uh, didn’t go so great.) The trip was still well worth it, though, because I got to eat a tofu salad partially made by a pair of robotic arms slung from the bottom of some kitchen cabinets.
