"Once proven, solar sail technology could enable a host of versatile space missions, including flying an advanced space-weather warning system to more quickly and accurately alert satellite operators and utilities on Earth of geomagnetic storms caused by coronal mass ejections from the sun," NASA said in a release.

The revolutionary technology behind 3D-printed car parts, food and guns can also be used to print batteries smaller than a grain of sand. Scientists have used a 3D printer to make linthium-ion microbatteries that can fit into tiny devices that had previously stumped engineers looking to power them for longer periods. The batteries were constructed from interlaced stacks of tiny battery electrodes, which conduct electricity, that are each smaller than the width of a single human hair.

Well, it seems less threatening than the ED-209.

The Knightscope K5 Autonomous Data Machine is an mobile robotic security guard with a slew of built-in sensors designed to patrol and monitor an area. The egg-shaped rolling robot has GPS and laser scanning built-in and utilizes prediction algorithms and social analytics to identify and assess potential concerns. Data collected by the robot is also made public to help crowdsource those predictions. Knightscope's creators plan to charge an hourly fee to rent the robot that will likely significantly undercut the going price of their human counterparts.
