The number one technological hurdle separating humanity from the Jetson Future we deserve is developing a reliable power supply. Even today, we're barely even able to keep out phones alive through the evening commute. But a radical departure in Lithium ion battery technology could help keep our power-hungry gadgets online for days, not hours. Read More >>

Powered skateboards have been around since the early 90's, but they've always seemed to require extra components — from handheld throttles to Microsoft Kinect-based sensor arrays — that could never quite capture the feel of a conventional deck. The ZBoard, with an electric drivetrain and weight-sensor control system, could be the first to actually pull it off. Read More >>
