Since I travel constantly for work, swapping my bulky MacBook Pro for a half-the-weight MacBook Air changed my life. Ultra-thin laptops like the Air—not to mention phones, tablets and iPods—come equipped with solid-state, or flash, memory, which writes data on tiny transistors rather than bulky spinning disks like conventional hard drives.
It’s rare that the first people who get to use a ground-breaking technology are third-world students and home tinkerers. But a new type of LCD, which requires less power than conventional displays and is viewable even in bright sunlight, was originally developed by the company Pixel Qi for the One Laptop Per Child project and is now available as a DIY replacement screen for netbook computers.
Like its more popular cousin the iPhone, the AppleTV is a beacon of simplicity in a category—set-top boxes that download and stream video from a computer or other device to your TV—crowded with wonky and complex options. Also like the iPhone, the AppleTV has its needless limitations: It plays video only in iTunes formats or from YouTube. No home movies or video (legally) downloaded from other sites are playable unless they’ve been specially converted.

Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
